Managing the iSCSI Target Gateway Chapter 13 The chapter provides information about iSCSI management in Fabric Manager and contains the following sections: • "About the iSCSI Target Gateway" on page 13-1 • "Viewing iSCSI Information" on page 13-2 • "Setting Up iSCSI Target Gateway Services" on page 13-7 About the iSCSI Target Gateway The Brocade iSCSI Target Gateway service provides the ability to leverage your shared Fibre Channel SAN resources with IP-based servers by using iSCSI links between your IP and FC SANs. After you configure the iSCSI Gateway, you can share resources such as data backup, data migration, security, and storage asset utilization across both your IP and FC SANs. As shown in Figure 13-1, the IP-based server can access the shared storage resource on the Fibre Channel SAN using iSCSI links. The iSCSI Target Gateway is supported only on the SilkWorm 48000 director with SilkWorm 48000 CP blades running Fabric OS 5.2.0 or higher, and configured with an FC4-16IP blade. The FC4-16IP port blade works as an iSCSI Target Gateway. Although iSCSI service is fabric wide, you can manage the iSCSI Target Gateway through any iSCSIcapable switch in a fabric. Any applied iSCSI Target Gateway change is propagated and enforced to the whole fabric. For additional information about iSCSI Target Gateway, see the iSCSI Gateway Service Administrator's Guide.

Managing the iSCSI Target Gateway

The chapter provides information about iSCSI management in Fabric Manager and contains the

following sections:

•

“About the iSCSI Target Gateway” on page 13-1

•

“Viewing iSCSI Information” on page 13-2

•

“Setting Up iSCSI Target Gateway Services” on page 13-7

About the iSCSI Target Gateway

The Brocade iSCSI Target Gateway service provides the ability to leverage your shared Fibre Channel

SAN resources with IP-based servers by using iSCSI links between your IP and FC SANs. After you

configure the iSCSI Gateway, you can share resources such as data backup, data migration, security, and

storage asset utilization across both your IP and FC SANs.

As shown in

Figure 13-1

, the IP-based server can access the shared storage resource on the Fibre

Channel SAN using iSCSI links.

The iSCSI Target Gateway is supported only on the SilkWorm 48000 director with SilkWorm 48000 CP

blades running Fabric OS 5.2.0 or higher, and configured with an FC4-16IP blade. The FC4-16IP port

blade works as an iSCSI Target Gateway.

Although iSCSI service is fabric wide, you can manage the iSCSI Target Gateway through any iSCSI-

capable switch in a fabric. Any applied iSCSI Target Gateway change is propagated and enforced to the

whole fabric.

For additional information about iSCSI Target Gateway, see the

iSCSI Gateway Service Administrator’s
