PowerScale OneFS Supportability and Compatibility Guide

File system protocols

The tables in this section list the file system protocols that are compatible with OneFS.

NFS

OneFS supports the Network File System (NFS) and Server Message Block (SMB) file system protocols. For information about how to configure NFS and SMB for OneFS, see the OneFS Administration Guide on the OneFS Info Hub for your OneFS version.

NOTE:Where provided, an exact OneFS version number indicates the minimum version of OneFS that is required.

NFS is a client and server application that lets users view and optionally store and update files on a network as if the files were saved in a local file directory. The NFS protocol is independent of the system, operating system, network architecture, and transport protocol.
