Name: SANsymphony
Type: Software-only (SDS)
Development Start: 1998
First Product Release: 1999
NEW
DataCore was founded in 1998 and began to ship its first software-defined storage (SDS) platform, SANsymphony (SSY), in 1999. DataCore launched a separate entry-level storage virtualization solution, SANmelody (v1.4), in 2004. This platform was also the foundation for DataCores HCI solution. In 2014 DataCore formally announced Hyperconverged Virtual SAN as a separate product. In May 2018 integral changes to the software licensing model enabled consolidation because the core software is the same and since then cumulatively called DataCore SANsymphony.
One year later, in 2019, DataCore expanded its software-defined storage portfolio with a solution especially for the need of file virtualization. The additional SDS offering is called DataCore vFilO and operates as scale-out global file system across distributed sites spanning on-premises and cloud-based NFS and SMB shares.
Recently, at the beginning of 2021, DataCore acquired Caringo and integrated its know how and software-defined object storage offerings into the DataCore portfolio. The newest member of the DataCore SDS portfolio is called DataCore Swarm and together with its complementary offering SwarmFS and DataCore FileFly it enables customers to build on-premises object storage solutions that radically simplify the ability to manage, store, and protect data while allowing multi-protocol (S3/HTTP, API, NFS/SMB) access to any application, device, or end-user.
DataCore Software specializes in the high-tech fields of software solutions for block, file, and object storage. DataCore has by far the longest track-record when it comes to software-defined storage, when comparing to the other SDS/HCI vendors on the WhatMatrix.
In April 2021 the company had an install base of more than 10,000 customers worldwide and there were about 250 employees working for DataCore.

Name: Acuity (AC)
Type: Hardware+Software (HCI)
Development Start: 2016
First Product Release: 2017
Pivot3 was founded in 2002 and began to ship its first hyper-converged storage (HCI) platform, Serverless Computing, in 2008. The first Pivot3 appliances were primarily positioned for storing video surveilance data.
Early 2016 Pivot3 acquired external storage system company NexGen Storage and with it its mature N5 operating system that leveraged strong storage QoS capabilities. Pivot3 succesfully combined the N5 OS with its own vSTAC (Virtual Storage and Compute) OS, into a new software stack called Acuity. The Acuity platform was launched in April 2017, although the technology features and software were available in 2016 as part of the Pivot3 SLX product. In July 2018 Pivot3 also switched to the Acuity codebase for its video surveillance appliances.
Pivot3 pursues a vision to radically simplify the datacenter by collapsing storage, compute and network resources onto a powerful, easy to deploy solution that reduces cost, risk and complexity. Pivot3 has by far the longest track-record when it comes to hyper-converged infrastructure, when comparing to the other SDS/HCI vendors in the WhatMatrix.
In July 2018 the company had an install base of more than 2,600 customers worldwide and there were more than 300 employees working for Pivot3.

Name: HPE SimpliVity 380
Type: Hardware+Software (HCI)
Development Start: 2009
First Product Release: 2013
SimpliVity was founded late 2009 and began to ship its first Hyper Converged Infrastructure (HCI) solution, OmniStack (OmniStack), in 2013. The core of the SimpliVity solution is the OmniStack OS combined with OmniStack Accellerator PCIe card. In January 2017 SimpliVity was acquired by HPE. In the second quarter of 2017 HPE introduced SimpliVity on HPE ProLiant server hardware and the platform was rebranded to HPE SimpliVity 380. In July 2018 HPE extended the HPE SimpliVity product family with the HPE SimpliVity 2600 featuring software-only deduplication and compression. In June 2019 HPE once again extended the SimpliVity product family with the HPE SimpliVity 325, a 1U server model featuring a single AMD EPYC CPU and all-flash storage.
In January 2018 HPE SimpliVity had a customer install base of approximately 2,000 customers worldwide. The number of employees working in the HPE SimpliVity division is unknown at this time.

Overall Design Complexity
Details
|
Medium
DataCore SANsymphony is able to meet many different use-cases because of its flexible technical architecture, however this also means there are a lot of design choices that need to be made. DataCore SANsymphony seeks to provide important capabilities either natively or tightly integrated, and this keeps the design process relatively simple. However, because many features in SANsymphony are optional and thus can be turned on/off, in effect each one needs to be taken into consideration when preparing a detailed design.

Low
Pivot3 Acuity was developed with simplicity in mind, both from a design and a deployment perspective. Pivot3 Acuitys uniform platform architecture is meant to be applicable to a wide variety of use-cases and seeks to provide important capabilities natively. Many advanced capabilities like deduplication and compression are always turned on. This minimizes the amount of design choices as well as the number of deployment steps.

Single-Layer
Dual-Layer
Single-Layer = servers function as compute nodes as well as storage nodes.
Dual-Layer = servers function only as storage nodes; compute runs on different nodes.
Single-Layer:
- SANsymphony is implemented as virtual machine (VM) or in case of Hyper-V as service layer on Hyper-V parent OS, managing internal and/or external storage devices and providing virtual disks back to the hypervisor cluster it is implemented in. DataCore calls this a hyper-converged deployment.
Dual-Layer:
- SANsymphony is implemented as bare metal nodes, managing external storage (SAN/NAS approach) and providing virtual disks to external hosts which can be either bare metal OS systems and/or hypervisors. DataCore calls this a traditional deployment.
- SANsymphony is implemented as bare metal nodes, managing internal storage devices (server-SAN approach) and providing virtual disks to external hosts which can be either bare metal OS systems and/or hypervisors. DataCore calls this a converged deployment.
Mixed:
- SANsymphony is implemented in any combination of the above 3 deployments within a single management entity (Server Group) acting as a unified storage grid. DataCore calls this a hybrid-converged deployment.
|
Single-Layer (primary)
Dual-Layer (secondary)
Single-Layer: Pivot3 Acuity is meant to be used as a storage platform as well as a compute platform at the same time. This effectively means that applications, hypervisor and storage software are all running on top of the same server hardware (=single infrastructure layer).
Pivot3 Acuity can also serve in a dual-layer model by providing storage to non-Acuity hypervisor hosts (Please view the compute-only scale-out option for more information).

Single-Layer
Single-Layer: HPE SimpliVity 380 is meant to be used as a storage platform as well as a compute platform at the same time. This effectively means that applications, hypervisor and storage software are all running on top of the same server hardware (=single infrastructure layer).
Although HPE SimpliVity 380 can serve in a dual-layer model by providing storage to non-HPE SimpliVity 380 hypervisor hosts, this would negate many of the platforms benefits as well as the financial business case. (Please view the compute-only scale-out option for more information).

Virtual Storage Controller
Kernel (Optional for Hyper-V)
The SANsymphony Controller is deployed as a pre-configured Virtual Machine on top of each server that acts as a part of the SANsymphony storage solution and commits its internal storage and/or externally connected storage to the shared resource pool. The Virtual Storage Controller (VSC) can be configured direct access to the physical disks, so the hypervisor is not impeding the I/O flow.
In Microsoft Hyper-V environments the SANsymphony software can also be installed in the Windows Server Root Partition. DataCore does not recommend installing SANsymphony in a Hyper-V guest VM as it introduces virtualization layer overhead and obstructs DataCore Software from directly accessing CPU, RAM and storage. This means that installing SANsymphony in the Windows Server Root Partition is the preferred deployment option. More information about the Windows Server Root Partition can be found here: https://docs.microsoft.com/en-us/windows-server/administration/performance-tuning/role/hyper-v-server/architecture
The DataCore software can be installed on Microsoft Windows Server 2019 or lower (all versions down to Microsoft Windows Server 2012/R2).
Kernel Integrated, Virtual Controller and VIB are each distributed architectures, having one active component per virtualization host that work together as a group. All three architectures are capable of delivering a complete set of storage services and good performance. Kernel Integrated solutions reside within the protected lower layer, VIBs reside just above the protected kernel layer, and Virtual Controller solutions reside in the upper user layer. This makes Virtual Controller solutions somewhat more prone to external actions (eg. most VSCs do not like snapshots). On the other hand Kernel Integrated solutions are less flexible because a new version requires the upgrade of the entire hypervisor platform. VIBs have the middle-ground, as they provide more flexibility than kernel integrated solutions and remain relatively shielded from the user level.

Virtual Storage Controller
The Pivot 3 Virtual Storage Controller is deployed as a pre-configured Virtual Machine on top of each server that acts as a part of the Pivot3 Acuity storage solution and commits its internal storage to the shared resource pool. The Virtual Storage Controller (VSC) can be configured direct access to the physical disks, so the hypervisor is not impeding the I/O flow. Pivot3 leverages its patented MPIO driver and VMwares DirectPath I/O framework to maximize storage performance.
MPIO Driver: Pivot3 has a patented MPIO driver in Acuity that allows an application server to see and, more importantly, read and write down every path available to the data. This improves both performance and storage resiliency.
DirectPath I/O (VMDirectPath) is a VMware framework that allows Acuity to directly communicate with the
underlying storage controllers, NVMe devices and disks for optimal performance benefit. Pivot3’s patented implementation against this framework allows for improved overall I/O performance for the
application layer and VMs.

iSCSI
FC
The SANsymphony software-only solution supports both iSCSI and FC protocols to present storage to hypervisor environments.
DataCore SANsymphony supports:
- iSCSI (Switched and point-to-point)
- Fibre Channel (Switched and point-to-point)
- Fibre Channel over Ethernet (FCoE)
- Switched, where host uses Converged Network Adapter (CNA), and switch outputs Fibre Channel
|
iSCSI
The Pivot3 Acuity platform supports the industry-standard iSCSI protocol to present storage to both hypervisor and non-hypervisor environments.
The iSCSI protocol can also be leveraged to present storage directly to VMs, which is often referred to as 'in-guest iSCSI'.
|
NFS
SMB
NFS is used as the storage protocol in vSphere environments.
SMB3 is used as the storage protocol in Hyper-V environments.
In virtualized environments In-Guest iSCSI support is still a hard requirements if one of the following scenarios is pursued:
- Microsoft Failover Clustering (MSFC) in a VMware vSphere environment
- A supported MS Exchange 2013 Environment in a VMware vSphere environment
Microsoft explicitely does not support NFS in both scenarios.

Any operating system currently not qualified for support can always be individually qualified with a specific SANsymphony version and will get full support after passing the self-qualification process.
SANsymphony provides virtual disks (block storage LUNs) to all of the popular host operating systems that use standard disk drives with 512 byte or 4K byte sectors. These hosts can access the SANsymphony virtual disks via SAN protocols including iSCSI, Fibre Channel (FC) and Fibre Channel over Ethernet (FCoE).
Mainframe operating systems such as IBM z/OS, z/TPF, z/VSE or z/VM are not supported.
SANsymphony itself runs on Microsoft Windows Server 2012/R2 or higher.

Because Pivot3 leverages the industry-standard iSCSI protocol, it enables hosts and physical workloads that reside outside of a Pivot3 cluster to access Pivot3 volumes by providing highly available block storage as iSCSI LUNs. The physical workloads can be stand-alone servers, Windows Failover Clusters (including MSSQL) or Oracle RAC. Also hypervisor workloads are supported to run on these separate hosts, such as Hyper-V and KVM.
Pivot3 quality engineering teams have so far qualified Acuity with external hosts running VMware ESX 6.x, Windows Server 2012/2016 and various flavors of Linux.

Docker Volume plugin (certified)
The DataCore SDS Docker Volume plugin (DVP) enables Docker Containers to use storage persistently, in other words enables SANsymphony data volumes to persist beyond the lifetime of both a container or a container host. DataCore leverages SANsymphony iSCSI and FC to provide storage to containers. This effectively means that the hypervisor layer is bypassed.
The Docker SDS Volume plugin (DVP) is officially 'Docker Certified' and can be downloaded from the Docker Hub. The plugin is installed inside the Docker host, which can be either a VM or a Bare Metal Host connect to a SANsymphony storage cluster.
For more information please go to: https://hub.docker.com/plugins/datacore-sds-volume-plugin
The Kubernetes CSI plugin can be downloaded from GitHub. The plugin is automatically deployed as several pods within the Kubernetes system.
For more information please go to: https://github.com/DataCoreSoftware/csi-plugin
Both plugins are supported with SANsymphony 10 PSP7 U2 and later.

Docker Volume Plugin (certified) + VMware VIB
vSphere Docker Volume Service (vDVS) can be used with VMware vSAN, as well as VMFS datastores and NFS datastores served by VMware vSphere-compatible storage systems.
The vSphere Docker Volume Service (vDVS) installation has two parts:
1. Installation of the vSphere Installation Bundle (VIB) on ESXi.
2. Installation of Docker plugin on the virtualized hosts (VMs) where you plan to run containers with storage needs.
The vSphere Docker Volume Service (vDVS) is officially 'Docker Certified' and can be downloaded from the online Docker Store.

7 models
HPE SimpliVity 380 hardware:
Gen10 (4000 and 6000)
Gen10 G
Gen10 H
The Gen10-6000 is best for high performance, IO intensive mixed workloads, whereas the Gen10-4000 is best for typical workloads (heavy reads/lower ratio of writes) at lower cost than the Gen10-6000. The difference between 4000/6000 is the SSD-type that is inserted in the server hardware.
HPE SimpliVity 380 Gen10 series offer 7 workload models:
Extra Small All SSD (SMB remote offices)
Small All SSD (Small Business and remote offices)
Medium All SDD (Mid-Size Enterprise Data Centers)
Large All SSD (Large Enterprise Data Centers)
Extra Large All SSD (Data-intensive Enterprise Data Centers)
G (Software-optimized for flexibility)
H (Storage optimized for backup and recovery)
Notes:
- The Extra Large workload model is only available for the Gen10-4000.
- Currently only the Extra Large workload model of the Gen10-4000 is not supported for Microsoft Hyper-V environments.
HPE SimpliVity 380 Gen 9 server hardware reached End-of-Life (EOL) status on December 31st 2018. This means that end users cannot acquire Gen 9 hardware any longer.

1, 2 or 4 nodes per chassis
Note: Because SANsymphony is mostly hardware agnostic, customers can opt for multiple server densities.
Note: In most cases 1U or 2U building blocks are used.
Also Super Micro offers 2U chassis that can house 4 compute nodes.
Denser nodes provide a smaller datacenter footprint where space is a concern. However, keep in mind that the footprint for other datacenter resources such as power and heat and cooling is not necessarily reduced in the same way and that the concentration of nodes can potentially pose other challenges.

Yes
DataCore does not explicitly recommend using different hardware platforms, but as long as the hardware specs are somehow comparable, there is no reason to insist on one or the other hardware vendor. This is proven in practice, meaning that some customers run their productive DataCore environment on comparable servers of different vendors.

A Pivot3 Acuity 'cluster' is called a Pivot3 virtual Performance Group (vPG). vPGs can only consist of like platforms (Hybrid nodes vs. All-flash nodes).
However, Pivot3 Acuity Hybrid (2x00) and All-flash (6x00) nodes can co-exist within the same Pivot3 Domain (aka 'Federation'). All nodes in the Domain can be managed via a single pane of glass.

For mixing HPE SimpliVity 380 nodes in a cluster, HPE recommends following these general guidelines:
- Only models of equal socket count are supported.
- All hosts should contain equal amounts of CPU & Memory.
- As a best practice, it’s recommended to use the same CPU model within a single cluster.
- Mixing server generations (Gen 9 and Gen 10) is allowed.
- Mixing Gen10 servers with legacy OmniCube/OmniStack platforms within the same cluster is allowed.
Heterogenous Federation Support: Although HPE SimpliVity 380 nodes cannot be mixed with HPE SimpliVity 2600 nodes or legacy SimpliVity nodes within the same cluster, they can coexist with such clusters within the same Federation.
HPE OmniStack 3.7.9 introduces support for using different versions of the OmniStack software within a federation. Some clusters can have hosts using HPE OmniStack 3.7.9 and other clusters can have hosts all using HPE OmniStack 3.7.8 and above. The hosts in each datacenter and cluster must use the same version of the software.

Storage-only
Storage+Compute: In a single-layer deployment existing SANsymphony clusters can be expanded by adding additional nodes running SANsymphony, which adds additional compute and storage resources to the shared pool. In a dual-layer deployment both the storage-only SANsymphony clusters and the compute clusters can be expanded simultaneously.
Compute-only: Because SANsymphony leverages virtual block volumes (LUNs), storage can be presented to hypervisor hosts not participating in the SANsymphony cluster. This is also beneficial to migrations, since it allows for online storage vMotions between SANsymphony and non-SANsymphony storage platforms.
Storage-only: In a dual-layer or mixed deployment both the storage-only SANsymphony clusters and the compute clusters can be expanded independent from each other.

This is also beneficial to migrations, since it allows for online storage vMotions between Pivot3 Acuity and non-Pivot3 Acuity storage platforms.
Storage-only: With the release of Acuity 10.6.1 Pivot3 introduces Storage appliances next to its HCI appliances. The Storage appliances have minimal CPU and Memory resources on board and only take part in the storage cluster so they can contribute to the shared storage pool of the HCI appliances. They do not take part in the hypervisor (compute) cluster, so no VMware vSphere licenses are required.

At maximum a Pivot3 Acuity X3 All-Flash vPG (aka 'cluster' ) consists of 8 X3-6x00 nodes. The maximum configuration consists of 2 Flash Accelerator nodes + 6 non-accelerator nodes.
A Pivot3 Acuity vPG (aka 'cluster' ) always needs to include 2 Flash Accelerator nodes, because the NMVe PCIe cards are used as write-buffer and all writes have to be mirrored between these two nodes to protect the incoming data streams.
A Pivot3 Domain can include multiple vPGs and therefore can have an unlimited number of nodes. All vPGs can be managed as one pool of resources from a single management pane. VMs can have data stored on multiple clusters and vMotion between any cluster works seamlessly.

Up to 32 storage nodes are supported within a single Federation. Multiple Federations can be used in either single-site or multi-site deployments, allowing for a scalable as well as a flexible solution. Data protection can be configured to run in between federations.
Cluster scale enhancements (16 nodes instead of 8 nodes within a single cluster) apply to new as well as existing SimpliVity clusters that run OmniStack 3.7.7.
HPE SimpliVity supports up to 96 nodes within a single Federation. For specific use-cases a Request for Product Qualification (RPQ) process can be initiated to authorize more than 96 storage nodes within a single Federation. The largest known HPE SimpliVity 380 field deployment counts approximately 70 nodes within a single Federation.
HPE SimpliVity 380 also supports adding compute nodes to a storage node cluster in vSphere environments.

Small-scale (ROBO)
Details
|
2 Node minimum
DataCore prevents split-brain scenarios by always having an active-active configuration of SANsymphony with a primary and an alternate path.
In the case SANsymphony servers are fully operating but do not see each other, the application host will still be able to read and write data via the primary path (no switch to secondary). The mirroring is interrupted because of the lost connection and the administrator is informed accordingly. All writes are stored on the locally available storage (primary path) and all changes are tracked. As soon as the connection between the SANsymphony servers is restored, the mirror will recover automatically based on these tracked changes.
Dual updates due to misconfiguration are detected automatically and data corruption is prevented by freezing the vDisk and waiting for user input to solve the conflict. Conflict solutions could be to declare one side of the mirror to be the new active data set and discarding all tracked changes at the other side, or splitting the mirror and merge the two data sets into a 3rd vDisk manually.
|
3 Node minimum (data center)
1 Node minimum (ROBO)
Pivot3 Acuity supports a minimum of 3 X-series nodes when local High Availability (HA) is required. The minimum base configuration consists of 2 Flash Accelerator nodes + 1 non-accelerator node. Two Accelerator nodes are required, because the NMVe PCIe cards are used as write-buffer and all writes are mirrored between these two nodes.
Pivot3 Acuity also supports 1-node configurations when local HA is not required, eg. in ROBO deployments.
|
1 Node minimum (2 Nodes for local HA)
HPE SimpliVity 380 supports single-node configurations in a site, which can bring huge cost savings. In single-node deployments HPE SimpliVity 380s advanced backup features can be leveraged for data protection. HPE SimpliVity 380 also supports 2-node configurations without sacrificing any of the data reduction and data protection capabilities. The HPE SimpliVity 380 XS-model is ideal for ROBO deployments.
All the remote sites can be centrally managed from a single dasboard at the central site.

Partial
DataCores core approach is to provide storage resources to the applications without having to worry about data locality. But if data locality is explicitly requested, the solution can partially be designed that way by configuring the first instance of all data to be stored on locally available storage (primary path) and the mirrored instance to be stored on the alternate path (secondary path). Furthermore every hypervisor host can have a local preferred path, indicated by the ALUA path preference.
By default data does not automatically follow the VM when the VM is moved to another node. However, virtual disks can be relocated on the fly to other DataCore node without losing I/O access, but this relocation takes some time due to data copy operations required. This kind of relocation usually is done manually, but we allow automation of such tasks and can integrate with VM orchestration using PowerShell for example.
Whether data locality is a good or a bad thing has turned into a philosophical debate. Its true that data locality can prevent a lot of network traffic between nodes, because the data is physically located at the same node where the VM resides. However, in dynamic environments where VMs move to different hosts on a frequent basis, data locality in most cases requires a lot of data to be copied between nodes in order to maintain the physical VM-data relationship. The SDS/HCI vendors today that choose not to use data locality, advocate that the additional network latency is negligible.
|
None
Pivot3 Acuity enables every drive in every node throughout the vPG (virtual performance group or cluster) to contribute to the storage performance and capacity of every volume presented by Acuity. After a VM is moved to another Acuity X5 node, data remains in place and does not follow the VM because data is wide-striped and available across all nodes.

Full
When a VM is created, it is optimally placed on the best 2 nodes available. When data is written, it is deduplicated and compressed on arrival, and then stored on the local node as well as a dedicated partner node. To keep the performance optimal through the VMs lifecycle, OmniStack automatically creates VMware vSphere DRS affinity rules and policies. This is called Intelligent Workload Optimization. VMware DRS is made aware of where the data of an individual VM is. In effect, the VM follows the data rather than having the data follow the VM, as this prevents heavy moves of data to the VM. When a HPE SimpliVity 380 node is added to the federation, the DRS rules related to OmniStack are automatically re-evaluated.
Currently HPE SimpliVity 380s DRS/Dynamic Optimization features are not available for Hyper-V environments.

Read/Write Cache
DataCore SANsymphony accelerates reads and writes by leveraging the powerful processors and large DRAM memory inside current generation x86-64bit servers on which it runs. Up to 8 Terabytes of cache memory may be configured on each DataCore node, enabling it to perform at solid state disk speeds without the expense. SANsymphony uses a common cache pool to store reads and writes in.
SANsymphony read caching essentially recognizes I/O patterns to anticipate which blocks to read next into RAM from the physical back-end disks. That way the next request can be served from memory.
When hosts write to a virtual disk, the data first goes into DRAM memory and is later destaged to disk, often grouped with other writes to minimize delays when storing the data to the persistent disk layer. Written data stays in cache for re-reads.
The cache is cleaned on a first-in-first-out (FiFo) basis. Segment overwrites are performed on the oldest data first for both read- and write cache segment requests.
SANsymphony prevents the write cache data from flooding the entire cache. In case the write data amount runs above a certain percentage watermark of the entire cache amount, then the write cache will temporarily be switched to write-through mode in order to regain balance. This is performed fully automatically and is self-adjusting, per virtual disk as well as on a global level.
|
Read Cache and Write Buffer
DRAM is used by Acuitys Dynamic Data Path Engine to provide read-ahead cache acceleration. Data is copied
from NVMe PCIe flash or disk (HDD or SSD) into DRAM to provide faster access to the data.
GlobalCache: Pivot3 Acuity also uses the DRAM inside each node as a high performance cache to provide an initial landing point for data as it is passed from the NVMe PCIe flash tier to the erasure coded persistent storage tier (HDD or SSD).

DRAM (mirrored)
If caching is turned on (default=on), any write will only be acknowledged back to the host after it has been succesfully stored in DRAM memory of two separate physical SANsymphony nodes. Based on de-staging algorithms each of the nodes eventually copies the written data that is kept in DRAM to the persistent disk layer. Because DRAM outperforms both flash and spinning disks the applications experience much faster write behavior.
Per default, the limit of dirty-write-data allowed per Virtual Disk is 128MB. This limit could be adjusted, but there has never been a reason to do so in the real world. Individual Virtual Disks can be configured to act in write-through mode, which means that the dirty-write-data limit is set to 0MB so effectively the data is directly written to the persistent disk layer.
DataCore recommends that all servers running SANsymphony software are UPS protected to avoid data loss through unplanned power outages. Whenever a power loss is detected, the UPS automatically signals this to the SANsymphony node and write behavior is switched from write-back to write-through mode for all Virtual Disks. As soon as the UPS signals that power has been restored, the write behavior is switched to write-back again.
|
NVMe PCIe (mirrored)
NVMe PCIe serves as a very performant storage medium for a read/write mirrored journal that is split between two accelerator nodes.
When an application sends a write request, it is mirrored between the NVMe PCIe flash cards on two Acuity X3/X5 Accelerator nodes for high availability and redundancy. Once both copies are stored, the receiving node acknowledges the write completion to the host. Once the write is acknowledged, the system will copy the data from NVMe PCIe flash to disk (HDD or SSD). Reads, writes, and modifies of the original copy occur in NVMe PCIe flash. At this point, the copy on disk is only used in the event that a rebuild on the NMVe PCIe flash tier is required. Lastly, if the data that is stored in NVMe PCIe flash is not being accessed frequently, the Acuity X5 node will evict it to make room for more active data based on the QoS priorities and targets. The decision to evict data is made in real-time based on access patterns, current performance levels and data-reduction ratios.
NVMe flash is able to deliver 2x the performance of 12Gbps SAS and up to 6x the performance of 6Gbps SATA.
Pivot3 Acuitys platform architecture requires two Flash Accelerator nodes to be part of any virtual Performance Group (vPG aka 'cluster'), regardless if SSD or HHD is placed underneath.
NVMe = Non-volatile memory express
PCIe = Peripheral Component Interconnect Express

2-way and 3-way Mirroring (RAID-1) + opt. Hardware RAID
DataCore SANsymphony software primarily uses mirroring techniques (RAID-1) to protect data within the cluster. This effectively means the SANsymphony storage platform can withstand a failure of any two disks or any two nodes within the storage cluster. Optionally, hardware RAID can be implemented to enhance the robustness of individual nodes.
SANsymphony supports Dynamic Data Resilience. Data redundancy (none, 2-way or 3-way) can be added or removed on-the-fly at the vdisk level.
A 2-way mirror acts as active-active, where both copies are accessible to the host and written to. Updating of the mirror is synchronous and bi-directional.
A 3-way mirror acts as active-active-backup, where the active copies are accessible to the host and written to, and the backup copy is inaccessible to the host (paths not presented) and written to. Updating of the mirrors active copies is synchronous and bi-directional. Updating of the mirrors backup copy is synchronous and unidirectional (receive only).
In a 3-way mirror the backup copy should be independent of existing storage resources that are used for the active copies. Because of the synchronous updating all mirror copies should be equal in storage performance.
When in a 3-way mirror an active copy fails, the backup copy is promoted to active state. When the failed mirror copy is repaired, it automatically assumes a backup state. Roles can be changed manually on-the-fly by the end-user.
DataCore SANsymphony 10.0 PSP9 U1 introduced System Managed Mirroring (SMM). A multi-copy virtual disk is created from a storage source (disk pool or pass-through disk) from two or three DataCore Servers in the same server group. Data is synchronously mirrored between the servers to maintain redundancy and high availability of the data. System Managed Mirroring (SMM) addresses the complexity of managing multiple mirror paths for numerous virtual disks. This feature also addresses the 256 LUN limitation by allowing thousands of LUNs to be handled per network adapter. The software transports data in a round robin mode through available mirror ports to maximize throughput and can dynamically reroute mirror traffic in the event of lost ports or lost connections. Mirror paths are automatically and silently managed by the software.
The System Managed Mirroring (SMM) feature is disabled by default. This feature may be enabled or disabled for the server group.
With SANsymphony 10.0 PSP10 adds seamless transition when converting Mirrored Virtual Disks (MVD) to System Managed Mirroring (SMM). Seamless transition converts and replaces mirror paths on virtual disks in a manner in which there are no momentary breaks in mirror paths.

Erasure Coding (EC1/EC3/EC5)
Global Virtual Sparing
The Pivot3 Acuity platform leverages patented Erasure Coding technology. Pivot3 Acuity Erasure Coding requires at least 3 nodes in a vPG. Pivot3 Acuity Erasure Coding is configured on a per volume basis, so EC levels can be mixed within the same vPG.
Configurable Erasure Coding levels:
EC1: Protects against 1 disk failure event OR 1 node failure event.
EC3: Protects against 3 simultaneous disk failure events OR 1 drive failure event + 1 node failure event.
EC5: Protects against 5 simultaneous disk failure events OR 2 drive failure events + 1 node failure event.
The Pivot3 Acuity platform also leverages a patented Global Virtual Sparing methodology. Whenever a volume is created, it is known what the required capacity for sparing is. Therefore, a small percentage of every drive is reserved for this capacity, meaning that a virtual spare spanning the entirety of the cluster, is created for each volume.
Global Virtual Sparing has two major advantages:
- The overall net capacity is significantly improved, since there is no longer the requirement for a single drive per node to be reserved for sparing. Also, as the system scales, the percentage required for sparing on each
drive decreases and more capacity is made available for application data.
- Since every drive has a small amount of sparing reservation, the performance impact of the failure and the
subsequent data migration or rebuild is distributed across all of the other drives in the vPG. This significantly improves rebuild times and reduces the performance impact on the system during failure conditions.

1 Replica (2N)
+ Hardware RAID (5, 6 or 60)
HPE SimpliVity 380 uses replicas to protect data within the cluster. In addition, hardware RAID is implemented to enhance the robustness of individual nodes.
Replicas+Hardware RAID: Before any write is acknowledged to the host, it is synchronously replicated on a designated partner node. This means that with 2N one instance of data that is written is stored on the local node and another instance of that data is stored on the designated partner node in the cluster. When a physical disk fails, hardware RAID maintains data availability.
Only when more than 2 disks fail within the same node, data has to be read from the partner node instead. Given the high level of redundancy within and across nodes, the desire to reduce unnecessary I/O, and the fact that most node outages are easily recoverable, node level redundancy is re-established based on a user initiated action.
The hardware RAID level that is applied depends on drive count in an individual node:
2 drives = RAID1
4-5 drives = RAID5
8-12 drives = RAID6
14-20 drives = RAID60 (2 per RAID6 set)

Not relevant (usually 1-node appliances)
Manual configuration (optional)
Manual designation per Virtual Disk is required to accomplish this. The end-user is able to define which node is paired to which node for that particular Virtual Disk. However, block failure protection is in most cases irrelevant as 1-node appliances are used as building blocks.
SANsymphony works on an N+1 redundancy design allowing any node to acquire any other node as a redundancy peer per virtual device. Peers are replacable/interchangable on a per Virtual Disk level.

Data Corruption Detection
Details
|
N/A (hardware dependent)
SANsymphony fully relies on the hardware layer to protect data integrity. This means that the SANsymphony software itself does not perform Read integrity checks and/or Disk scrubbing to verify and maintain data integrity.
|
Metadata verification (software)
Predictive drive analysis (software)
Disk scrubbing (software)
The Pivot3 Acuity platform utilizes the following mechanisms to prevent data corruption:
- Metadata verification via checksums. Metadata is replicated across nodes. Metadata is also replicated within the node.
- Metadata validation on load. Self-check and version control.
- Predictive drive failure analysis.
- Background disk scrub with error recovery from EC.
- Write-error will fail drive.
Pivot3 Acuity has a built-in predictive drive analysis function to monitor a number of aspects around drive performance within the virtual Performance Group (vPG). By proactively monitoring disk health for CRC errors, drive seek times, IO response times and a host of Smart Drive Functions, it is possible to predict, and therefore proactively, fail a drive within the vPG.
|
Read integrity checks (CLI)
Disk scrubbing (software)
While writing data, checksums are created and stored as part of the inline deduplication process. When one of the underlying layers detects data corruption, a checksum comparison is performed and when required, another copy of the data is used to repair the corrupted copy in order to stay compliant with the configured protection level.
Read integrity checks can be enabled through the CLI.
Disk Scrubbing, termed 'RAID Patrol' by HPE SimpliVity 380, is a background process that is used to perform checksum comparisons of all data stored within the solution. This way stale data is also verified for corruption.

Local + Remote
SANsymphony snapshots are always created on one side only. However, SANsymphony allows you to create a snapshot for the data on each side by configuring two snapshot schedules, one for the local volume and one for the remote volume. Both snapshot entities are independent and can be deleted independently allowing different retention times if needed.
There is also the capability to pair the snapshot feature along with asynchronous replication which provides you with the ability to have a third site long distance remote copy in place with its own retention time.

Per VM (Vvols) or Volume
With SANsymphony the rough hierarchy is: physical disk(s) or LUNs -> Disk Pool -> Virtual Disk (=logical volume).
Although DataCore SANsymphony uses block-storage, the platform is capable of attaining per VM-granularity if desired.
In Microsoft Hyper-V environments, when a VM with vdisks is created through SCVMM, DataCore can be instructed to automatically carve out a Virtual Disk (=storage volume) for every individual vdisk. This way there is a 1-to-1 alignment from end-to-end and snapshots can be created on the VM-level. The per-VM functionality is realized by installing the DataCore Storage Management Provider in SCVMM.
Because of the per-host storage limitations in VMware vSphere environments, VVols is leveraged to provide per VM-granularity. DataCore SANsymphony Provider v2.01 is certified for VMware ESXi 6.5 U2/U3, ESXi 6.7 GA/U1/U2/U3 and ESXi 7.0 GA/U1.

Built-in (native)
DataCore SANsymphony incorporates Continuous Data Protection (CDP) and leverages this as an advanced backup mechanism. As the term implies, CDP continuously logs and timestamps I/Os to designated virtual disks, allowing end-users to restore the environment to an arbitrary point-in-time within that log.
Similar to snapshot requests, one can generate a CDP Rollback Marker by scripting a call to a PowerShell cmdlet when an application has been quiesced and the caches have been flushed to storage. Several of these markers may be present throughout the 14-day rolling log. When rolling back a virtual disk image, one simply selects an application-consistent or crash-consistent restore point from just before the incident occurred.
|
Built-in (native)
By combining Pivot3 Acuitys native snapshot feature with its native remote replication mechanism, backup copies can be created on remote Pivot Acuity vPGs (clusters).
A snapshot is not a backup:
1. For a data copy to be considered a backup, it must at the very least reside on a different physical platform (=controller+disks) to avoid dependencies. If the source fails or gets corrupted, a backup copy should still be accessible for recovery purposes.
2. To avoid further dependencies, a backup copy should reside in a different physical datacenter - away from the source. If the primary datacenter becomes unavailable for whatever reason, a backup copy should still be accessible for recovery purposes.
When considering the above prerequisites, a backup copy can be created by combining snapshot functionality with remote replication functionality to create independent point-in-time data copies on other SDS/HCI clusters or within the public cloud. In ideal situations, the retention policies can be set independently for local and remote point-in-time data copies, so an organization can differentiate between how long the separate backup copies need to be retained.
Apart from the native features, Pivot3 Acuity can be used in conjuntion with external data protection solutions like VMwares free-of-charge vSphere Data Protection (VDP) backup software, as well as any hypervisor compatible 3rd party backup application. VDP is part of the vSphere license and requires the deployment of virtual backup appliances on top of vSphere.
No specific integration exists between Pivot3 Acuity and VMware VDP.

Pivot3 Acuity supports remote replication of storage snapshots to another Acuity vPG (cluster) within the same datacenter or in a remote datacenter.
Pivot3 Acuity supports remote replication of storage snapshots to a Pivot3 Acuity appliance hosted on Amazon Web Services (AWS). Pivot3 Cloud Edition is an Amazon EC2 instance that uses Amazon S3 storage for storing incoming data from on-premises Pivot3 Acuity deployments. It can serve as an off-site repository for short-term and long-term backups, as well as hosting a DR copy. Pivot3 Cloud Edition is deployed as an Amazon Machine Image (AMI) so there is no manual installation involved.
All Pivot3 AWS appliances are currently deployed as t2.2xlarge (8 vCPUs; 32GB RAM) EC2 instances with EBS st1 (2/4/8/16TB HDD) for data storage and EBS gp2 (200GB SSD) for journal space.
Pivot3 AWS cloud appliances can be managed from the vCenter Plugin.

By default CDP creates crash consistent restore points. Similar to snapshot requests, one can generate a CDP Rollback Marker by scripting a call to a PowerShell cmdlet when an application has been quiesced and the caches have been flushed to storage.
Several CDP Rollback Markers may be present throughout the 14-day rolling log. When rolling back a virtual disk image, one simply selects an application-consistent, filesystem-consistent or crash-consistent restore point from (just) before the incident occurred.
In a VMware vSphere environment, the DataCore VMware vCenter plug-in can be used to create snapshot schedules for datastores and select the VMs that you want to enable VSS filesystem/application consistency for.
|
File System Consistent (Windows); Application Consistent (MS Apps on Windows)
Pivot3 Acuity provides the option to enable Microsoft VSS integration when configuring a backup policy. This ensures application-consistent backups are created for MS Exchange and MS SQL database environments.
Pivot3 Acuity also integrates with VMware vCenter to create software snapshots of VMs before taking hardware snapshots of volumes in order to maintain data consistency.

vSphere: File System Consistent (Windows), Application Consistent (MS Apps on Windows)
Hyper-V: File System Consistent (Windows)
HPE SimpliVity 380 provides the option to enable Microsoft VSS integration when configuring a backup policy or when initiating manual backups using the CLI backup command. This ensures application-consistent backups are created for MS Exchange and MS SQL database environments.
In OmniStack 3.6.1 support was added for VSS on virtual machines running SQL Server 2012/2016 on the Windows Server 2012 R2 operating system.
HPE SimpliVity 380 also still provides the option to create crash-consistent backups by setting consistency to 'none'.

Remote Replication Type
Details
|
Built-in (native)
DataCore SANsymphonys remote replication function, Asynchronous Replication, is called upon when secondary copies will be housed beyond the reach of Synchronous Mirroring, as in distant Disaster Recovery (DR) sites. It relies on a basic IP connection between locations and works in both directions. That is, each site can act as the disaster recovery facility for the other. The software operates near-synchronously, meaning that it does not hold up the application waiting on confirmation from the remote end that the update has been stored remotely.
|
Built-in (native)
Pivot3 Acuity is capable of protecting individual volumes and groups of volumes by using a-synchronous remote replication techniques.
Once protection has been set up for a volume, Pivot3 Acuity periodically takes a replication snapshot of storage volume on the local cluster and replicates (copies) the snapshot to the paired remote cluster. In the event of a disaster at the local cluster, the most recently replicated snapshot of each protected volume is recovered at the remote cluster.
Optionally Pivot3 Acuity can quiesce the virtual machines through VMware vCenter integration before taking the replication snapshot.

On-premises deployments of DataCore SANsymphony can use Microsoft Azure cloud as an added replication location to safeguard highly available systems. For example, on-premises stretched clusters can replicate a third copy of the data to MS Azure to protect against data loss in the event of a major regional disaster. Critical data is continuously replicated asynchronously within the hybrid cloud configuration.
To allow quick and easy deployment a ready-to-go DataCore Cloud Replication instance can be acquired through the Azure Marketplace.
MS Azure can serve only as a data repository. This means that VMs cannot be restored and run in an Azure environment in case of a disaster recovery scenario.

SANsymphony Asynchronous Replication is not checkpoint-based but instead replicates continuously. This way data loss is kept to a minimum (seconds to minutes). End-users can inject custom consistency checkpoints based on CDP technology which has no minimum time slot/frequency.
|
15 minutes (Asynchronous)
The minimum frequency per replication task is 15 minutes.
|
GUI: 10 minutes (Asynchronous)
CLI: 1 minute (Asynchronous)
Continuous (Stretched Cluster)
Although setting the remote replication frequency below 10 minutes is possible through the Command Line Interface (CLI), it should not be used for a large number of protected VMs as this could severely impact performance.

Remote Replication Granularity
Details
|
VM or Volume
With SANsymphony the rough hierarchy is: physical disk(s) or LUNs -> Disk Pool -> Virtual Disk (=logical volume).
Although DataCore SANsymphony uses block-storage, the platform is capable of attaining per VM-granularity if desired.
In Microsoft Hyper-V environments, when a VM with vdisks is created through SCVMM, DataCore can be instructed to automatically carve out a Virtual Disk (=storage volume) for every individual vdisk. This way there is a 1-to-1 alignment from end-to-end and snapshots can be created on the VM-level. The per-VM functionality is realized by installing the DataCore Storage Management Provider in SCVMM.
Because of the per-host storage limitations in VMware vSphere environments, VVols is leveraged to provide per VM-granularity. DataCore SANsymphony Provider v2.01 is VMware certified for ESXi 6.5 U2/U3, ESXi 6.7 GA/U1/U2/U3 and ESXi 7.0 GA/U1.
|
Volume
Up to five protection policies can be assigned to a single volume. A single protection policy can have up to 3 Tasks.
The idea of multiple Tasks is similar to setting up backup retention policies using a grandfather-father-son approach, each with different snapshotting frequencies and number recovery points that need to be retained.

2+sites = two or more active sites, 0/1 or more tie-breakers
Theoretically up to 64 sites are supported.
SANsymphony does not require a quorum or tie-breaker in stretched cluster configurations, but can be used as an optional component. The Virtual Disk Witness can provide a tie-breaker role if for instance redundant inter site paths are not implemented. The tie-breaker node (server or device) must be other than the two nodes presenting a virtual disk. Access to the Virtual Disk Witness is leading for storage node behavior.
There are 3 ways to configure the stretched cluster without any tie-breakers:
1. Default: in a split-brain scenario both sides stay active allowing upper infrastructure layers (OS/database/application) to make a decision (eg. clustering principles). In any case SANsymphony prevents a merge when there is a risk to data integrity, and the end-user has to make the choice on how to proceed next (which side is true)
2. Select one side to go inaccessible
3. Select both sides to go inaccessible.
|
N/A
At this time Pivot3 does not support Acuity X5 clusters that are stretched across data centers.
|
3-sites: two active sites + tie-breaker in 3rd site (optional)
HPE SimpliVity calls the tie-breaker 'arbiter'. The use of the arbiter automates failover decisions in order to avoid split-brain scenarios like network partitions and remote site failures. The arbiter can be either on-premises or hosted as a cloud instance, and is recommended but not a hard requirement. The arbiter is a small Windows service, so it can run about anywhere, as long as it has network access to both active sites. A single arbiter may be shared by multiple clusters in the federation. Installing an additional arbiter for every 4,000 virtual machines helps ensure best performance and distributes workloads.
In VMware vSphere environments the arbiter is a hard requirement for 2-node clusters and stretched cluster configurations. Furthermore, HPE recommends using the arbiter in non-stretched cluster configurations with 4 HPE OmniStack hosts.
Currently for Microsoft Hyper-V environments (2-node clusters) the arbiter is a hard requirement.
The HPE OmniStack 3.7.9 version of Arbiter introduced support for clusters with hosts that use HPE OmniStack 3.7.8 and other clusters with hosts that use HPE OmniStack 3.7.9. The federation can contain a mix of clusters with those two versions. However, all the hosts within the same cluster must use the same version.

Replicas: 1N-2N at each active site
DataCore SANsymphony provides enhanced stretched cluster availability by offering local fault protection with In Pool Mirroring. With In Pool Mirroring you can choose to mirror the data inside the local Disk Pool as well as mirror the data across sites to a remote Disk Pool. In the remote Disk Pool data is then also mirrored. All mirroring happens synchronously.
1N-2N: With SANsymphony Stretched Clustering, there can be either 1 instance of the data at each site (no In Pool Mirroring) or 2 instances of the data a each site (In Pool RAID-1 Mirroring).

SANsymphony provides integrated and individually selectable inline deduplication and compression. In addition, SANsymphony is able to leverage post-processing deduplication and compression options available in Windows 2016/2019 as an alternative approach.
|
Software
Pivot3 Acuity includes data reduction technology, an inline pattern recognition engine that compresses and deduplicates incoming data. Acuity software recognizes common patterns in the data stream and immediately strips them at an individual block level.
|
Hardware (PCIe)
HPE SimpliVity 380 has its deduplication- and compression engine embedded into a PCIe card, consisting of FPGA, NVRAM and DRAM, thus all deduplication/compression is hardware accelerated and fully offloaded from the hypervisor host.

Dedup/Compr. Process
Details
|
Deduplication: Inline (post-ack)
Compression: Inline (post-ack)
Deduplication/Compression: Post-Processing (post process)
NEW
Deduplication can be performed in 4 ways:
1. Immediately when the write is processed (inline) and before the write is ackowledged back to the originator of the write (pre-ack).
2. Immediately when the write is processed (inline) and in parallel to the write being acknowledged back to the originator of the write (on-ack).
3. A short time after the write is processed (inline) so after the write is acknowleged back to the originator of the write - eg. when flushing the write buffer to persistent storage (post-ack)
4. After the write has been committed to the persistent storage layer (post-process).
The first and second methods, when properly integrated into the solution, are most likely to offer both performance and capacity benefits. The third and fourth methods are primarily used for capacity benefits only.
DataCore SANSymphony 10 PSP12 and above leverage both inline deduplication and compression, as well as post process deduplication and compression techniques.
With inline deduplication incoming writes first hit the memory cache of the primary host and are replicated to the cache of a secondary host in an un-deduplicated state. After the blocks have been written to both memory caches, the primary host acknowledges the writes back to the originator. Each host then destages the written blocks to the persistent storage layer. During destaging, written blocks are deduplicates and/or compressed.
Windows Server 2019 deduplication is performed outside of IO path (post-processing) and is multi-threaded to speed up processing and keep performance impact minimal.

4. After the write has been committed to the persistent storage layer (post-process).
The first and second methods, when properly integrated into the solution, are most likely to offer both performance and capacity benefits. The third and fourth methods are primarily used for capacity benefits only.
In the case of Pivot3 the inline on-ack method has both performance and capacity benefits by reducing write amplification by coalescing written data before destaging and by accelerating reads.
Pivot3 uses IO pattern matching as its method of deduplication and compression. This process is inline and happens on IO block acknowledgment; it is performed entirely in memory. As soon as the data is ingested into memory and determined to be a duplicate or compressible, the system adds a metadata pointer to the reference in memory and acknowledges to the host immediately, so processes can continue.
Pivot3 deduplication ans compression is a feature present in both All-flash and Hybrid systems.

Dedup/Compr. Type
Details
|
Optional
NEW
By default, deduplication and compression are turned off. For both inline and post-process, deduplication and compression can be enabled.
For inline deduplication and compression the feature can be turned on per node. The entire node represents a global deduplication domain. Deduplication and compression work across pools and across vDisks. Individual pools can be selected to participate in capacity optimization. Either deduplication or compression or both can be selected per individual vDisk. Pools can host both capacity optimized and non-capacity optimized vDisks at the same time. The optional capacity optimization settings can be added/changed/removed during operation for each vDisk.
For post-processing the feature can be enabled per pool. All vDisks in that pool would be deduplicated and compressed. Each pool is an independent deduplication domain. This means only data in the pool is capacity optimized, but not across pools. Additionally, for post-processing capacity optimization can be scheduled so admins can decide when deduplication should run.
With SANsymphony the rough hierarchy is: physical disk(s) or LUNs -> Disk Pool -> Virtual Disk (=logical volume).

Pool (post-processing deduplication domain)
Node (inline deduplication domain)
NEW
With SANsymphony the rough hierarchy is: physical disk(s) or LUNs -> Disk Pool -> Virtual Disk (=logical volume).
For inline deduplication and compression raw physical disks are added to a capacity optimization pool. The entire node represents a global deduplication domain. Deduplication and compression work across pools and across vDisks. Individual pools can be selected to participate in capacity optimization.
The post-processing capability provided through Windows Server 2016/2019 is highly scalable and can be used with volumes up to 64 TB and files up to 1 TB in size. Data deduplication identifies repeated patterns across files on that volume.
|
Storage Cluster (vPG)
Pivot3 Acuity inline deduplication works globally, which means that deduplication happens across all nodes in a vPG (=storage cluster).
A vPG should not be confused with a vSphere cluster. For example: an 8-node vPG can be split into two 4-node vSphere clusters; two 8-node vPGs can be combined to form a 16-node vSphere cluster.
|
Federation
HPE SimpliVity 380 inline deduplication works globally, which means that deduplication happens across the entire data set within a federation (a single federation consists of on or multiple clusters). The data set includes primary data as well as backup copies.
HPE SimpliVity 380 inline deduplication also works across sites. This means that SimplVity OmniStack will talk to the other site and only send changed blocks.
As HPE SimpliVity 380 inline deduplication and compression that is performed by the hardware accelerator card provides essential value and does not incur any performance penalty, it cannot be turned off.

Dedup/Compr. Granularity
Details
|
4-128 KB variable block size (inline)
32-128 KB variable block size (post-processing)
NEW
With inline deduplication and compression, the data is organized in 128 KB segments. Depending on the optimization setting, a write into such a segment first gets compressed (when compression is selected) and then a hash is generated. If the hash is unique, the 128 KB segment is written back and the hash is added to the deduplication hash-table. If the hash is not unique, the segment is referenced in the deduplication hash table and discarded. The smallest chunk in the segment can be 4 KB.
For post-processing the system leverages deduplication in Windows Server 2016/2019, files within a deduplication-enabled volume are segmented into small variable-sized chunks (32–128 KB), duplicate chunks are identified, and only a single copy of each chunk is physically stored.
|
256 KB - 1.5 MB variable block size
Pivot3 Acuity deduplication uses 256K - 1.5MB variable block segments.

|
N/A
At this time Pivot3 does no guarantee a minimum savings. Pivot3 states that reduction rates will vary per workload and use case.
|
90% (10:1) capacity savings across storage and backup combined
Capacity space savings are due to deduplication+compression and include both storage and backups.
90% savings is the equivalent of 10:1 efficiency in the Datacenter panel in the HPE SimpliVity tab within the vSphere Client. Efficiency is calculated across all HPE SimpliVity systems in a VMware Datacenter. It’s the ratio of storage capacity that would have been used on a comparable traditional storage solution to the physical storage that is actually used in the HPE SimpliVity hyperconverged infrastructure. ‘Comparable traditional solutions’ are storage systems that provide VM-level synchronous replication for storage and backup and do not include any deduplication or compression capability.
The savings/efficiency are based on the assumption that you configure a backup policy to take at least one HPE SimpliVity backup per day of every virtual machine on every HPE SimpliVity system in a given VMware Datacenter with those backups retained for 30 days. If backups are performed more frequently and/or retained for a longer period, you will enjoy even greater efficiency. The data change rate is assumed to be up to 5% per day with up to 30% growth rate of the data over a duration of 30 contiguous days.

Full (optional)
Data rebalancing needs to be initiated manually by the end-user. It depends on the specific use case and end-user environment if this makes sense. When end-users want to isolate new workloads and corresponding data on new nodes, data rebalancing is not used.
|
Full
Data is automatically redistributed evenly across all Pivot3 Acuity nodes in the virtual Performance Group (vPG aka 'cluster') when a node is added.
When a node is removed from a Pivot3 Acuity vPG (aka 'cluster'), the Erasure Code calculations are redone in CPU and the data is redistributed as a background process (throttled to minimise impact on performance). Because of the data protections distributed nature, it avoids the pain associated with rebuilding traditional RAID groups.
There is no user-intervention required for any the redistribution activities.
|
Partial
Data that is already present before adding a node is not rebalanced across all nodes within a Federation. This is in accordance with HPE SimpliVity 380s data locality strategy. However, data is automatically rebalanced across all nodes before removing/evicting a node from a Federation.
Data can be rebalanced at any time, but currently requires a HPE SimpliVity 380 Support engagement. Some customers have regular, support-initiated cadences for rebalancing.

IOPs and/or MBps Limits
QoS is a means to ensure specific performance levels for applications and workloads. There are two ways to accomplish this:
1. Ability to set limitations to avoid unwanted behavior from non-critical clients/hosts.
2. Ability to set guarantees to ensure service levels for mission-critical clients/hosts.
SANsymphony currently supports only the first method. Although SANsymphony does not provide support for the second method, the platform does offer some options for optimizing performance for selected workloads.
For streaming applications which burst data, it’s best to regulate the data transfer rate (MBps) to minimize their impact. For transaction-oriented applications (OLTP), limiting the IOPs makes most sense. Both parameters may be used simultaneously.
DataCore SANsymphony ensures that high-priority workloads competing for access to storage can meet their service level agreements (SLAs) with predictable I/O performance. QoS Controls regulate the resources consumed by workloads of lower priority. Without QoS Controls, I/O traffic generated by less important applications could monopolize I/O ports and bandwidth, adversely affecting the response and throughput experienced by more critical applications. To minimize contention in multi-tenant environments, the data transfer rate (MBps) and IOPs for less important applications are capped to limits set by the system administrator. QoS Controls enable IT organizations to efficiently manage their shared storage infrastructure using a private cloud model.
More information can be found here: https://docs.datacore.com/SSV-WebHelp/quality_of_service.htm
In order to achieve consistent performance for a workload, a separate Pool can be created where selected vDisks are placed. Alternatively 'Performance Classes' can be assigned to differentiate between data placement of multiple workloads.

The pre-defined service levels govern how the QoS engine treats the targets in order to maintain Mission Critical performance, then Business Critical performance and then Non-critical performance.
The pre-defined service levels also govern how the read-warm cache is getting populated:
Policy 1 – Mission Critical – 1 hit per 1MB Region
Policy 2 – Business Critical – 4 hits per 1MB Region
Policy 3 – Business Critical – 16 hits per 1MB Region
Policy 4 – Non-Critical – read-warm disabled
Policy 5 – Non-Critical – read-warm disabled
The pre-defined service levels also govern how read-ahead is used:
Policy 1 – Mission Critical – enabled
Policy 2 – Business Critical – enabled
Policy 3 – Business Critical – enabled
Policy 4 – Non-Critical – read-ahead disabled
Policy 5 – Non-Critical – read-ahead disabled

N/A
Quality-of-Service (QoS) is a means to ensure specific performance levels for applications and workloads. There are two ways to accomplish this:
1. Ability to set limitations to avoid unwanted behavior from non-critical VMs.
2. Ability to set guarantees to ensure service levels for mission-critical VMs.
HPE SimpliVity 380 currently does not offer any QoS mechanisms.

Virtual Disk Groups and/or Host Groups
SANsymphony QoS parameters can be set for individual hosts or groups of hosts as well as for groups of Virtual Disks for fine grained control.
In a VMware VVols (=Virtual Volumes) environment a vDisk corresponds 1-to-1 to a virtual disk (.vmdk). Thus virtual disks can be placed in a Disk Group and a QoS Limit can then be assigned it. DataCore SANsymphony Provider v2.01 has VVols certification for VMware ESXi 6.5 U2/U3, ESXi 6.7 GA/U1/U2/U3 and ESXi 7.0 GA/U1.
In Microsoft Hyper-V environments, when a VM with vdisks is created through SCVMM, DataCore can be instructed to automatically carve out a Virtual Disk (=storage volume) for every individual vdisk. This way there is a 1-to-1 alignment from end-to-end and QoS Limits can be applied on the virtual disk level. The 1-to-1 allignment is realized by installing the DataCore Storage Management Provider in SCVMM.

Per volume
Because Pivot3 Acuity presents block-based storage volumes, QoS Policies can be applied to VMware datastores and in-guest iSCSI disks.

Per VM/Virtual Disk/Volume
With SANsymphony the rough hierarchy is: physical disk(s) or LUNs -> Disk Pool -> Virtual Disk (=logical volume).
In SANsymphony 'Flash Pinning' can be achieved using one of the following methods:
Method #1: Create a flash-only pool and migrate the individual vDisks that require flash pinning to the flash-only pool. When using a VVOL configuration in a VMware environment, each vDisk represents a virtual disk (.vmdk). This method guarantees all application data will be stored in flash.
Method #2: Create auto-tiering pools with at least 1 flash tier. Assign the Performance Class “Critical” to the vDisks that require flash pinning and place them in the auto-tiering pool. This will effectively and intelligently put as much of the data that resides in the vDisk in the flash tier as long that the flash tier has enough space available. Therefore this method is on a best-effort basis and dependent on correct sizing of the flash tier(s).
Methods #1 and #2 can be uses side-by-side in the same DataCore environment.

Not relevant (All-Flash only)
The HPE SimpliVity 380 platform is not available as a hybrid (flash+magnetic) configuration and as such has no need for a ' Flash Pinning' feature.

Built-in (native)
Pivot3 Acuity 10.6 introduced native data encryption capabilities for storage volumes, however encryption keys need to be generated by 3rd party security tools (currently only HyTrust KeyControl is supported).
With Acuity data encryption volumes can be encrypted on creation through policy configuration. Pivot3 designed its data encryption algorithms to leverage Intel Xeon CPUs AES New Instructions (AES NI) to ensure minimal performance impact and low overhead. However, as encrypting a volume does cause a small degradation in performance, Pivot3 recommends encrypting only those volumes that contain sensitive information.
Data encryption can also be established using 3rd party security software.

Using DataCores native management console, Virtual Disk Templates can be leveraged to populate storage policies. Available configuration items: Storage profile, Virtual disk size, Sector size, Reserved space, Write-trough enabled/disabled, Storage sources, Preferred snapshot pool, Accelerator enabled/disabled, CDP enabled/disabled.
Virtual Disk Templates integrate with System Center Virtual Machine Manager (SCVMM), VMware Virtual Volumes (VVol) and OpenStack. Virtual Disk Templates are also fully supported by the REST-API allowing any third-party integration.
Using Virtual Volumes (VVols) defined through DataCore’s VASA provider, VMware administrators can self-provision datastores for virtual machines (VMs) directly from their familiar hypervisor interface. This is possible even for devices in the DataCore pool that don’t natively support VVols and never will, as SANsymphony can be used as a storage-virtualization layer for these devices/solutions. DataCore SANsymphony Provider v2.01 has VVols certification for VMware ESXi 6.5 U2/U3, ESXi 6.7 GA/U1/U2/U3 and ESXi 7.0 GA/U1.

The DataCore SANsymphony GUI offers delegated administration to secondary users through fine-grained Role-based Access Control (RBAC). The administrator is able to define Virtual Disk ownership as well as privileges associated with that particular ownership. Owners must have Virtual Disk privileges in an assigned role in order to perform operations on the virtual disk. Access can be very refined. For example, one owner may have the privilege to create a snapshot of a virtual disk, but not have the ability to serve or unserve the same virtual disk. Privilege sets define the operations that can be performed. For instance, in order for an owner to perform snapshot, rollback, or replication operations, they would require those privilege sets in an assigned role.

N/A
Pivot3 Acuity does not provide any end-user self service capabilities of its own.
A self service portal enables end-users to access a portal where they can provision and manage VMs from templates, eliminating administrator requests or activity.
Self-Service functionality can be enabled by leveraging for instance VMware vRealize Automation (vRA). This requires a separate VMware license.

Unified
All storage related features and functionality are built into the DataCore SANsymphony platform. The consolidation means, that only one product needs to be installed and upgraded and minimal dependencies exist with other software.
Integration with 3rd party systems (e.g. OpenStack, vSphere, System Center) are delivered seperately but are free-of-charge.
|
Partially Distributed
For a number of features and functions the Pivot3 Acuity platform relies on other components that need to be installed and upgraded next to the core vSphere platform. Examples are backup/restore and remote replication software. As a result some dependencies exist with other software.

SW Upgrade Execution
Details
|
Rolling Upgrade (1-by-1)
Each SANsymphony update is packaged in an installation Wizard which contains a fully guided upgrade process. The upgrade process checks all system requirements and performs a system health before starting the upgrade process and before moving from one node to the next.
The user can also decide to upgrade a SANsymphony cluster manually and follow all steps that are outlined in the Release Notes.
|
Rolling Upgrade (1-by-1)
Pivot3 provides GUI-based non-disruptive rolling upgrades of the Acuity platform as well as the underlying server firmware.
The upgrade only gets committed once all nodes within the vPG (aka cluster) are at the same state and the update is stable.
|
Rolling Upgrade (1-by-1)
OmniStack upgrades are initiated against the Federation and are completed in an automated, rolling fashion. OmniStack Accelerator Card upgrades are included in the OmniStack upgrade process. Reboots of a host are only required if there is an associated OmniStack Accelerator Card firmware update. The updating of the firmware only happens occasionally.
HPE SimpliVity 380 provides a Fast Upgrade Manager that manages the entire upgrade process, from detection to execution.
HPE SimpliVity 380 OmniStack 3.7.7 provides Upgrade Manager support for simulteaneously upgrading hosts in a cluster when the hosts do not have powered-on guest VMs, accelerating the upgrade process.
HPE SimpliVity 380 OmniStack 3.7.9 provides Upgrade Manager support for upgrading HPE OmniStack software at the cluster level. This feature only works when upgrading from HPE OmniStack 3.7.8 to HPE OmniStack 3.7.9.

Hardware dependent
Some server hardware vendors offer rolling upgrade options with their base software or with a premium software suite. With some other server vendors, BIOS and Baseboard Management Controller (BMC) updated have to be performed manually and 1-by-1.
DataCore provides integrated firmware-control for FC-cards. This means the driver automatically loads the required firmware on demand.

Rolling Upgrade (1-by-1)
In HPE SimpliVity OmniStack 3.7.10 the Upgrade Manager allows upgrading host firmware (SVT Service Pack for Proliant) on supported platforms.
Previously, server firmware and drivers had to be updated by rebooting the server from an ISO that automatically installed the Service Pack for Proliant (SPP). Because this is an offline procedure, it was required to migrate VMs and put the node in maintenance mode first.
Upgrade Manager now allows you to generate firmware upgrade reports
for individual hosts or clusters. These reports show version (previous and
current) and state information for the individual firmware components.

Predictive Analytics
Details
|
Partial
Capacity Management: DataCore SANsymphony Analysis and Reporting supports depletion monitoring of the capacity, complements pool space threshold warnings by regularly evaluating the rate of capacity consumption and estimating when space will be depleted. The regularly updated projections give you a chance to add more storage to the pool before you run out of storage. It also helps you do a better job of capacity planning with fewer surprises. To help allocate costs, especially in private cloud and hosted cloud services, SANsymphony generates reports quantifying the storage resources consumed by specific hosts or groups of hosts. The reports tally several parameters.
Health Monitoring: A combination of system health checks and access to device S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) alerts help to isolate performance and disk problems before they become serious.
DataCore Insight Services (DIS) offers additional capabilites including log-analytics for predictive failure analysis and actionable insights - including hardware.
DIS also provides predictive capacity trend analysis in order to pro-actively warn about licensing limitations being reached within x days and/or disk pools running out of capacity.

Pivot3 Acuity includes predictive analytics specific to the following areas:
- Proactive supportability: sensor data from multiple components (flash, disk, node, etc) within the system is analysed for predictive failures and self-healing of the system. For instance, if a drive is failing (not yet failed), system will automatically spare it out and phone home order a new one. Also, we analyse and predict when flash wear-out may occur and display/alarm this information to the customer and phone home.
- Capacity and Performance Planning: complete suite of metrics and dashboards available to the customer for capacity (current and predictive future) and performance to aid with expansion planning. All these metrics are included in a daily phone-home package sent to Pivot3 support cloud.
- Realtime IO Path/Data Placement manipulation: every IO is tracked and analysed in order to meet the SLAs defined by the customer via the built-in policy engine. Data placement in the system (RAM, NVMe, SSD, HDD) is governed by policy. The system uses predictive analytics and automation to make sure right IO path queueing and data placement is in effect to meet SLAs. Policy changes can be automated via built-in scheduler and CLI/APIs.
