Isns For Linux Installation And Setup; Setting Up Isns - Novell LINUX ENTERPRISE SERVER 10 - INSTALLATION AND ADMINISTRATION 08-05-2008 Installation Manual

Suppose you have a company that has 100 iSCSI initiators and 100 iSCSI targets. De-
pending on your configuration, all iSCSI initiators could potentially try to discover and
connect to any of the 100 iSCSI targets. This could create a discovery and connection
nightmare. By grouping initiators and targets into discovery domains, you can prevent
iSCSI initiators in one department from discovering the iSCSI targets in another depart-
ment. The result is that the iSCSI initiators in a specific department only discover those
iSCSI targets that are part of the department's Discovery Domain.
