ESXi can access a designated NFS volume located on a NAS server, mount the volume, and use it for its storage needs. You can use NFS volumes to store and boot virtual machines in the same way that you use VMFS datastores.

ESXi supports the following shared storage capabilities on NFS volumes:

vMotion

VMware DRS and VMware HA

ISO images, which are presented as CD-ROMs to virtual machines

Virtual machine snapshots

When you work with NFS storage, the following considerations apply:

The maximum size of NFS datastores depends on the support that an NFS server provides. ESXi does not impose any limits on the NFS datastore size.

If you use non-ASCII characters to name datastores and virtual machines, make sure that the underlying NFS server offers internationalization support. If the server does not support international characters, use only ASCII characters, otherwise unpredictable failures might occur.
