SnapDrive is supported on vFiler units when using the iSCSI protocol.
If a storage system uses the optional MultiStore feature of Data ONTAP software to create virtual storage systems (vFiler units), SnapDrive can create, connect to, and manage LUNs on the vFiler units in the same way it does on the physical storage system. You accomplish this by providing the name for the vFiler unit rather than the name of the physical storage system to create a connection. It is transparent to the host whether the attached storage system is a physical storage system or a virtual vFiler unit.
