Network File System (NFS) ESXi includes NFS Clients for NFS v3 and NFS v4.1 Use only one NFS version to access a datastore No upgrade from NFS v3 to NFS v4.1 – migration only NFS datastores can be mounted read-only Supports vMotion, HA, DRS, and FT (FT not supported on NFS v4.1) Virtual disks created on NFS datastores as thin-provisioned by default unless hardware acceleration supporting Reserve Space operation is used. (NFS v4.1 does not support hardware acceleration) How presentation will benefit audience: Adult learners are more interested in a subject if they know how or why it is important to them.
