Figure 53. iSCSI Target Access
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.
