iSCSI gateway service overview

This chapter describes the FC4-16IP blade iSCSI gateway service. The iSCSI gateway service is

supported only on the Brocade 48000 director running Fabric OS v6.1.0 or later with one or more

iSCSI-enabled FC4-16IP blades.

The FC4-16IP iSCSI gateway service is an intermediate device in the network, allowing iSCSI

initiators in an IP SAN to access and utilize storage in a Fibre Channel (FC) SAN as shown in the

figure below.

It provides the following services to the iSCSI initiators:

• Access to the fabric using virtual FC devices (iSCSI virtual initiator)

• Supports target registration to an iSCSI Name Server (iSNS) for discovery
