Nutanix calls its native fileserving feature Acropolis File Services (AFS). Today AFS is a 3rd generation solution.
With Acropolis File Services (AFS) Nutanix offers a software-defined scale-out file serving solution for Windows environments with a single namespace. The solution is highly available, scalable, and supports Active Directory and LDAP integration, Windows previous versions, user and share quotas, as well as Access Based Enumeration (ABS). AFS can be used to host home directories, department shares and user profiles.
AFS 3.0 supports a maximum size of 40TB for a general file share and a maximum size of 200TB per FSVM for a home share. AFS 3.0 support a maximum of 4,000 connections per FSVM (12 vCPU; 96GB RAM).
AFS 3.0 supports SMB 2.0/2.1/3.0 as well as NFS v4 protocols to provide file shares/exports for Windows, Apple Mac, Linux and UNIX clients. AFS 3.0 can be leveraged in ESXi and AHV environments only (so no support for Hyper-V).
AFS 3.0 provides SMB 3.0 basic protocol support, so without specific SMB 3.0 features. AFS 3.0 does not support NFS v3 file protocol.
NFS v4 exports can be either distributed or non-distributed. A distributed export ("sharded") means the data is spread across all Nutanix Fle Services VMs (FSVMs) to help improve performance and resiliency. A non-distributed export ("non-sharded") means all data is contained in a single FSVM.
AFS 3.0 introduces an API that allows third-party developers to implement backup server change file tracking. This means that the API allows the backup application to record and collect information about any changes to the files in each snapshot sent to the backup server, thus providing a log of all file changes across snapshots.
AFS 3.0 introduces an API that allows third-party developers to implement file activity monitoring in their applications. Thsi means that the API allows an application to collect information about every action on each file in a file server and thus supports audit logging (eg. to a syslog server) and Global Name Space.
AFS 3.0.1 introduces integration with Peer Software. Refer to the Peer Software knowledge base for system requirements and configuration.
Nutanix Acropolis File Services (AFS) is included in the Ultimate edition, but requires a separate license (AFS Standalone License) for Starter and Pro editions.
AOS 5.2 for AHV on IBM Power Systems does not yet offer AFS support.
