NFS datastores use the PowerStore File System, a 64-bit file system architecture, which includes several advantages and a maximum size of 256 TB. Other features include file system shrink, extend, replication, snapshots, and more.
Before using NFS datastores, create an NFS-enabled NAS server. You must create a file system associated with this NAS server and an NFS export. VMware ESXi hosts require read/write and root access to the NFS export. In vSphere, administrators must create an NFS datastore that uses the PowerStore file system.
With the introduction of PowerStoreOS 3.0, a new VMware type file system is supported on PowerStore. This file system is designed for VMware NFS datastore use cases and contains several enhancements for VMware environments. For more information about VMware Filesystems on PowerStore, see the document Dell PowerStore: File Capabilities.
