Identities - SANRAD V-Switch User Manual

Once a volume has a LUN and is attached to a target, it is accessible to iSCSI
initiators. Each initiator can access, read and write into the volume.

Identities

To allow selective iSCSI initiator access to iSCSI target volumes, the V-
Switch uses identities to define pools of initiators. An identity is a user-
defined list of iSCSI initiators. An identity can contain from one to multiple
initiators, with each initiator having a unique WWUI.
In Figure 54, there are four iSCSI initiators in Identity A: WWUI 1, 2,5 and
8.
