The following figure shows an iSCSI gateway that has three iSCSI VTs and two iSCSI initiators.

CONTROLLING ACCESS TO THE ISCSI VT
You can limit access to iSCSI VTs using a discovery domain (DD), a group of the iSCSI initiators and
iSCSI VTs. The iSCSI initiators can access only the iSCSI VTs that are in the same discovery domain.
Discovery domains are grouped together in a discovery domain set (DDSet). The active discovery
domain set enforces the fabric-wide iSCSI VT access. Only the DDs in the active DDSet are
enforced. You can create multiple discovery domain sets but only one set can be active at a time.
It is also possible to present a single iSCSI portal IP address to the iSCSI initiator when the default
iSCSI port configuration is in effect, and connection redirection is disabled on the blade.
