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: NetApp HCI
Type: Hardware+Software (HCI)
Development Start: 2016
First Product Release: 2017
SolidFire, founded at the end of 2009, released its first Software Defined Storage (SDS) solution in november 2012. In february 2016 NetApp officially completed its acquisition of SolidFire, thus gaining acces to the SDS/HCI market.
NetApp HCIs (NetApp HCI) worldwide customer install base is unknown at this time. The number of employees working in the NetApp HCI division is also unknown at this time.

Name: HPE SimpliVity 2600
Type: Hardware+Software (HCI)
Development Start: 2009
First Product Release: 2018
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 HPE SimpliVity 2600 featuring software-only deduplication and compression.
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.

Software Pricing Model
Details
|
Capacity based (per TB)
NEW
DataCore SANsymphony is licensed in three different editions: Enterprise, Standard, and Business.
All editions are licensed per capacity (in 1 TB steps). Except for the Business edition which has a fixed price per TB, the more capacity that is used by an end-user in each class, the lower the price per TB.
Each edition includes a defined feature set.
Enterprise (EN) includes all available features plus expanded Parallel I/O.
Standard (ST) includes all Enterprise (EN) features, except FC connections, Encryption, Inline Deduplication & Compression and Shared Multi-Port Array (SMPA) support with regular Parallel I/O.
Business (BZ) as entry-offering includes all essential Enterprise (EN) features, except Asynchronous Replication & Site Recovery, Encryption, Deduplication & Compression, Random Write Accelerator (RWA) and Continuous Data Protection (CDP) with limited Parallel I/O.
Customers can choose between a perpetual licensing model or a term-based licensing model. Any initial license purchase for perpetual licensing includes Premier Support for either 1, 3 or 5 years. Alternatively, term-based licensing is available for either 1, 3 or 5 years, always including Premier Support as well, plus enhanced DataCore Insight Services (predictive analytics with actionable insights). In most regions, BZ is available as term license only.
Capacity can be expanded in 1 TB steps. There exists a 10 TB minimum per installation for Business (BZ). Moreover, BZ is limited to 2 instances and a total capacity of 38 TB per installation, but one customer can have multiple BZ installations.
Cost neutral upgrades are available when upgrading from Business/Standard (BZ/ST) to Enterprise (EN).
|
Per Node
Capacity based (per TB)
NetApp HCI software licensing is separate from hardware pricing. The decoupling provides a choice between per node and capacity pricing. The capacity pricing model allows usage of the licensed storage capacity across an entire enterprise (multiple sites, multiple solutions). Currently 25TB and 100TB packs exist.
There are no separate software editions with regards to NetApp HCI. Each node comes equiped with an all-inclusive feature set. This means that without exception all storage software capabilities are available for use.
NetApp HCI can be connected to NetApp Cloud Central to enable additional features and services such as Kubernetes-as-a-Service with NetApp Kubernetes Service and fileservices-as-a-Service with NetApp Cloud Volumes. Some cloud services come with an additional charge.
The NetApp HCI solution comes with a 90-day trial license for VMware, which allows the NetApp Deployment Engine (NDE) to install and configure the VMware software. VMware software licenses must be purchased separately.\
|
Per Node (all-inclusive)
Add-ons: RapidDR (per VM)
There is no separate software licensing for most platform integrated features. By default all software functionality is available regardless of the hardware model purchased.
The HPE SimpliVity 2600 per node software license is tied to the selected CPU and storage configuration.

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
NetApp HCI was developed with simplicity in mind, both from a design and a deployment perspective. NetApp HCIs uniform platform architecture is meant to be applicable to a wide variety of use-cases and seeks to provide important capabilities natively. There are only a handful of storage building blocks to choose from, and 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.

Deployment Architecture
Details
|
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.
|
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.
Dual-Layer: NetApp HCI is implemented exclusively in a dual-layer architecture consisting of compute-only nodes in one layer and storage-only nodes in a separate layer. This design choice was intentional as to allow for maximum flexibility and performance predictability.
|
Single-Layer
Single-Layer: HPE SimpliVity 2600 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 2600 can serve in a dual-layer model by providing storage to non-HPE SimpliVity 2600 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).

Hypervisor Deployment
Details

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.
|
None
Because of the design choice to keep compute and storage fully separated, the storage is served from the storage node cluster to the compute node cluster through the iSCSI storage protocol. In effect no solution components, eg. virtual storage controllers, need to be deployed on top of the compute nodes.

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
NetApp HCI only supports the iSCSI protocol in order to present storage to hypervisor hosts, bare-metal hosts and VMs.
|
NFS
NFS is used as the storage protocol in vSphere 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.

Built-in (native)
NetApp provides its own software plugins for container support (both Docker and Kubernetes) through its Trident open-source project.
More information can be found here: https://netapp-trident.readthedocs.io
NetApp also developed its own container platform software called 'NetApp Kubernetes Service'. NKS provides on-premises Kubernetes-as-a-Service (KaaS) in order to enable end-users to quickly adopt container services.
NetApp Kubernetes Service (NKS) is not a hard requirement for running Docker containers and Kubernetes on top of NetApp HCI, however it does make it easier to use and consume.
NKS system size requirements for NetApp HCI environments:
- 2x4 systems are not supported for production use. However, these can be used for demo work.
- 3x4 systems are the minimum production system size supported by NetApp.
- 4x4 systems are the recommended minimum size.

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.

HPE positions HPE Simplivity 2600 as a VDI Optimized Hyperconverged Solution. The platform is also beneficial for compute-intensive workload
use cases in high density environments.
The Gen10 6000-series is best for high performance, IO intensive mixed workloads, whereas the gen10 4000-series is best for typical workloads (heavy reads/lower ratio of writes) at lower cost than the 6000-series. The difference between 4000/6000 is the SSD-type that is inserted in the server hardware.
There are no HPE SimpliVity 2600 Hybrid (SSD+HDD) models to choose from.

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.
|
Yes
Compute and storage nodes can be mixed and matched as long as best practices are adhered to.
NetApp HCI allows any storage node type to be mixed within a single cluster, however one important rule is mandatory: no one storage node can be more than one-third of the total cluster capacity for high-availabity and self-healing purposes.
|
Partial
For mixing HPE SimpliVity 2600 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.
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 suppor 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.

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.

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.
|
4 Node minimum (2 storage + 2 compute)
Minimum configuration is 1 chassis with 4 nodes, consisting of 2 storage nodes and 2 compute nodes.
When leveraging a 2-node or 3-node storage cluster, 2 NetApp Witness nodes are deployed as virtual machines for arbitration purposes.

2 Node minimum
HPE SimpliVity 2600 supports 2-node configurations without sacrificing any of the data reduction and data protection capabilities. The HPE SimpliVity 2600 is ideal for ROBO deployments.

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.

None
NetApp HCI is based on a shared nothing storage architecture. NetApp HCI enables every drive in every storage node throughout the cluster to contribute to the storage performance and capacity of every volume presented by the Element software storage layer. When a VM is moved to another compute node, data remains in place and does not follow the VM because data is stored and available across all nodes residing in the cluster.
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 require 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.

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 2600 node is added to the federation, the DRS rules related to OmniStack are automatically re-evaluated.

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.

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.
|
NVRAM (mirrored)
NVRAM serves as a very performant storage medium for a read/write mirrored journal that is split between two NetApp HCI storage nodes.
When an application sends a write request, it is mirrored between the NVRAM on two NetApp HCI storage nodes for high availability and redundancy. Once both copies are stored, the primary node acknowledges the write completion to the host. Once the write is acknowledged, the system will copy the data from NVRAM to the persistent storage layer (SSD).

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.

1 Replica (2N)
NEW
NetApp HCI Double Helix data protection is a RAID-less data protection solution designed to maintain both data availability and performance regardless of failure condition. Helix data protection is a distributed replication algorithm that spreads at least two redundant copies of data across all drives in the system. This approach allows the system to absorb multiple failures across all levels of the storage solution while maintaining data redundancy and QoS settings.
If a drive should go down, NetApp HCI automatically rebuilds redundant data across all remaining drives in the cluster in minutes to maintain high availability with minimal impact to performance due to the platforms architecture. The more nodes in the cluster, the faster the activity occurs and the lower the overall impact. No matter where the failure occurs (drive, node, backplane, network or software failure), the recovery process is the same.

HPE SimpliVity 2600 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.

Block Failure Protection
Details
|
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.
|
Protection Domains
Block failure protection can be achieved by assigning chassis to different Protection Domains (aka Zones).
Protection Domains: Protection domains at the chassis level allow scaling of NetApp HCI clusters in such a way that
the failure of an entire chassis can be sustained even if there is more than one storage node in the chassis. The minimum allowed configuration is 3 chassis with 2 storage nodes each. The system automatically lays out data correctly when the configuration is compatible with Protection domains.
Beginning with Element OS 12.0, protection domain layouts can be customized to cover zones of storage nodes within a rack, or between multiple racks. This enables more flexibility in data resiliency and improves storage availability, especially in large scale installations.

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.
|
Read integrity checks
During writing of the data checksums are created and stored. When read again or accessed during system operations, the checksum is validated. If an issue is detected, the system automatically accesses the secondary copy and repairs the invalid copy.
|
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 2600, 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.

Snapshot Granularity
Details
|
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)
With regard to NetApp HCI volume back-ups can be created in two data formats:
- Native: a compressed format readable only by NetApp HCI storage systems.
- Uncompressed: an uncompressed format compatible with other systems.
|
Built-in (native)
HPE SimpliVity 2600 provides native backup capabilities. Its backup feature supports remote-replication, is deduplication aware and data is compressed over the wire.
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.

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.

A GUI-based configuration utility is provided to add, modify, and remove cluster information used by the NetApp HCI VSS hardware provider.
Utilizing VSS Snapshot capabilities with the NetApp HCI VSS hardware provider makes sure that Snapshot copies are application consistent with business applications that use NetApp HCI volumes on a system. A coordinated effort between VSS components provides this functionality.

HPE SimpliVity 2600 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 2600 also still provides the option to create crash-consistent backups by setting consistency to 'none'.

Restore Granularity

|
Entire 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.
When configuring the virtual environment as described above, effectively VM-restores are possible.
For file-level restores a Virtual Disk snapshot needs to be mounted so the file can be read from the mount. Many simultaneous rollback points for the same Virtual Disk can coexist at the same time, allowing end-users to compare data states. Mounting and changing rollback points does not alter the original Virtual Disk.

Entire Volume
Administrators are enabled to perform VM and single file restores by mounting a volume snapshot created by NetApp HCI.

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)
NetApp HCI supports replication to another NetApp HCI via Element Real-Time Replication or to an ONTAP AFF/FAS cluster via SnapMirror. The SnapMirror feature also allows replication to systems running ONTAP Select or Cloud Volumes ONTAP.

To remote sites
To MS Azure Cloud
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.

Continuous (near-synchronous)
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.
|
Continuous (Synchronous, Asynchronous)
NetApp HCI Real-Time Asynchronous Replication is not checkpoint-based but instead replicates continuously. This way data loss is kept to a minimum (seconds to minutes). The actual RPO is dependent on line latency that exists between the source and the destination site.
ONTAP SnapMirror is snapshot-based and has a minimum replication interval of 15 minutes.

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 NetApp does not support NetApp HCI 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).

Software
NetApp HCI includes data reduction technology, that compresses and deduplicates all incoming data cluster-wide across all volumes.
Compression is completely inline, with no performance impact. During a write, a block is compressed, and during the recycling process blocks are recompressed to provide even greater efficiency.
An internal garbage collection process cleans up blocks that are no longer referenced by any metadata, including Snapshot copies.

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.

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.
NetApp HCI leverages global inline deduplication and global inline as well as post compression techniques. Incoming writes are broken into 4K blocks, assigned a hash (BlockID), compressed and then written to the NVRAM of two storage nodes in order to protect the data. When the internal Block Service identifies that the BlockID already exists, which means that the data has already been committed to the persistent flash layer, it does not destage the data twice. When destaging unique compressed 4K blocks from NVRAM to the persistent flash layer, blocks going to the same SSD are consolidated into 1MB chunks.

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).

Always-on
NetApp HCIs data deduplication and compression features are always on and cannot be disabled as it is an integral component of the platform architecture providing both performance and efficiency. The fact that the storage subsystem has been completely separated from the compute subsystem in NetApp, deduplication and compression does not substract from compute resources. It also provides end-user simplicity.

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
NetApp HCI inline deduplication works globally, which means that deduplication happens across all nodes within a storage cluster.
|
Federation
HPE SimpliVity 2600 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 2600 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 2600 inline deduplication and compression that is performed by the software provides essential value and does not incur any significant 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.

HPE SimpliVity deduplication uses 4KB - 8KB variable block segments.

N/A
Microsoft provides the Deduplication Evaluation Tool (DDPEVAL) to assess the data in a particular volume and predict the dedup ratio.
|
Workload/Data Type dependent
NetApp uses pre-defined reduction ratios per workload for NetApp HCI based on testing. A capacity guarantee is provided to customers as part of the purchase. In exceptional scenarios a higher ratio may be agreed upon between NetApp and the individual customer organization.
|
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
NetApp HCI automatically rebalances data across nodes when a node is either added or removed. There is no user-intervention required for these 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 2600s 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 2600 Support engagement. Some customers have regular, support-initiated cadences for rebalancing.

DataCore SANsymphonys Auto-Tiering is a real-time intelligent mechanism that continuously positions data on the appropriate class of storage based on how frequently the data is accessed. Auto-Tiering leverages any combination of Flash and traditional disk technologies, whether it is internal or array based, with up to 15 different storage tiers that can be defined.
As more advanced storage technologies become available, existing tiers can be modified as necessary and additional tiers can be added to further diversify the tiering architecture.

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.

IOPs Limits (maximums)
IOPs Guarantees (minimums)
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.
NetApp HCI supports both methods through pre-defined performance policies per volume. These policies can be changed at any point in time and on-the-fly.
NetApp HCI provides the following three-dimensional QoS settings for every individual volume/Vvol:
- Minimum IOPS: The minimum number of IOPS guaranteed for the volume.
- Maximum IOPS: The maximum number of IOPS allowed for the volume.
- Burst IOPS: The maximum number of IOPS allowed over a short period of time for the volume.
The IOPS values entered are normalized to a 4K IO size. The configuration screen shows the calculation for 8K, 16K and 256K IO sizes, as well as MBps for Maximum Bandwidth.

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
Per vdisk (Vvols)
Because NetApp HCI presents block-based storage volumes, QoS Policies can be applied to VMware datastores, Raw Device Mappings (RDMs). This also extends to individual vdisks when Vvols is leveraged.

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.

Hardware: In SANsymphony deployments the encryption data service capabilities can be offloaded to hardware-based SED offerings available in server- and storage solutions.
Software: SANsymphony provides software-based data-at-rest encryption that is XTS-AES 256bit compliant.
|
Hardware: Self-encrypting drives (SEDs)
Software: Element OS encryption
NEW
Hardware-based encryption: NetApp HCI allows encryption of all data stored within the cluster. Self-encrypting drives are available on H410S/H610S storage nodes, with FIPS-certified drives in H610S-2F storage nodes.
All drives in NetApp HCI storage nodes leverage AES 256-bit encryption at the drive level. Each drive has its own encryption key, which is created when the drive is first initialized. When you enable the encryption feature, a cluster-wide password is created, and chunks of the password are then distributed to all nodes in the cluster. No single node stores the entire password. The password is then used to password-protect all access to the drives and must then be supplied for every read and write operation to the drive.
Enabling the encryption-at-rest feature does not affect performance or efficiency on the cluster. Additionally, if an encryption-enabled drive or node is removed from the cluster with the API or web UI, Encryption-at-Rest will be disabled on the drives.
Software-based encryption: Element 12.2 introduces software encryption at rest, which can be enabled when creating a new storage cluster (and is enabled by default when creating a SolidFire Enterprise SDS storage cluster). The encryption feature encrypts all data stored on the SSDs in the storage nodes and causes only a very small (~2%) performance impact on client IO.

NetApp ONTAP Select is an optional service provided with NetApp HCI. Deploying a single/dual node cluster of ONTAP Select within the NetApp HCI environment allows provisioning of file shares (SMB and NFS) via the ONTAP Select user interface on top of the NetApp HCI block storage. The ideal use cases are home directories and departmental file shares.
ONTAP Select is installed as part of a post NetApp Deployment Engine (NDE), customer-driven workflow.
NetApp HCI v1.8 allows the automatic configuration of NetApp ONTAP Select 9.7 file services as part of the NetApp HCI deployment process streamlined by NetApp Deployment Engine (NDE). NDE v1.8 deploys a single-node NetApp ONTAP Select cluster. A second node can be added afterwards to form an HA-pair with the first node.
NetApp ONTAP Select nodes are VMware virtual machines deployed on top of the NetApp HCI Compute node cluster. The NetApp ONTAP Select clusters initial licensing supports 2-8TB of raw storage capacity. ONTAP Select datastores are mapped to VMware virtual disks (VMDKs) that reside on the NetApp HCI storage cluster.
NetApp ONTAP Select requires a separate license (Standard or Premium).

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.
Using Classifications and StoragePools defined through DataCore’s Storage Management Provider, Hyper-V administrators can self-provision virtual disks and pass-through LUNS for virtual machines (VMs) directly from their familiar SCVMM interface.

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.

The NetApp HCI platform 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 VMware vRealize Orchestration (vRO). This requires a separate VMware license. NetApp HCI officially supports vRealize Orchestration (vRO) through a plug-in.

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)
NEW
NetApp HCI clustered architecture allows nondisruptive storage software upgrades (Element OS) on a rolling node-by-node basis. Upgrades can be performed during production hours with little to no workload impact.
Element OS 12.2 introduces maintenance mode, which enables taking a storage node offline for
maintenance such as software upgrades or host repairs, while preventing a full sync of all data. If one or more nodes need maintenance, I/O impact can be minimized to the rest of the storage cluster by enabling maintenance mode for those nodes before beginning.
Software upgrades on compute nodes are orchestrated by VMware Update Manager (VUM). This procedure covers driver upgrades.
|
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 provided 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.

FW Upgrade Execution
Details
|
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.
|
Manual (written procedure)
NetApp HCI provides the option to update firmware, including BIOS and BMC, on compute nodes by booting into a firmware update boot media (USB drive, virutal media via BMC). Today, this process is manual and performed on one compute node at a time. NetApp Support can assist administators with performing this task.
On storage nodes, firmware is updated in conjuction with an update of the Element OS software.
|
Rolling Upgrade (1-by-1)
In HPE SimpliVity OmniStack 4.0.0 the Upgrade Manager allows upgrading host firmware (SVT Service Pack for Proliant) on HPE SimpliVity 2600 Gen10.
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.

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.
