Overview of iSCSI gateway service
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
Manages iSCSI initiator access control using discovery domains and a discovery domain set
Session management, such as session tracking and performance monitoring
Session authentication using CHAP
NOTE
The FC4-16IP iSCSI gateway service is not compatible with other iSCSI gateway platforms, including
Brocade iSCSI Gateway or the Brocade Multiprotocol Router.
