ESXi supports VMkernel-based NFS mounts for storing virtual disks on NFS datastores.

In addition to storing virtual disks on NFS datastores, you can also use NFS Datastores as a central repository for ISO images and virtual machine templates. For more information about creating NFS datastores, see vSphere Storage.

ESXi supports NFS version 3 over Layer 2 and Layer 3 Network switches. Host servers and NFS storage arrays must be on different subnets and the network switch must handle the routing information.
