Overview of iSCSI gateway service

FIGURE 5 iSCSI VT advanced LUN mapping

Identifying iSCSI components

See Figure 2 for a basic implementation with an IP network. The Brocade iSCSI gateway service

supports IQN only to identify the iSCSI components, such as the iSCSI initiator and iSCSI VT. Every

iSCSI initiator and iSCSI VT on the same network and SAN must have a unique IQN.

The format of an IQN is as follows:

type.date.naming authority:<user_defined>

A Brocade-created IQN includes “2002-12.com.brocade” and the device WWN as shown in the

following example:

Type Date Auth User defined

+--++-------+ +------+ +---- -----------------+

iqn.2002-12.com.brocade:10:00:00:05:1e:aa:bb:cc

A Microsoft-created IQN includes “microsoft” and the system name:

iqn.2003-11.com.microsoft:win2k-sn-192168101

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