14 iSCSI gateway service
iSCSI gateway service overview
This chapter describes the HP StorageWorks B-Series iSCSI Director Blade gateway service. The iSCSI
gateway service is supported only on the HP StorageWorks 4/256 SAN Director running Fabric OS 5.2.0
or later with one or more iSCSI-enabled HP StorageWorks B-Series iSCSI Director Blade.
The HP StorageWorks B-Series iSCSI Director Blade 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
Figure 32
.
Figure 32
iSCSI gateway network
The iSCSI gateway network provides the following services to the iSCSI initiators:
•
Access to the fabric using virtual FC devices (iSCSI virtual initiator)
•
Support for target registration to an iSCSI Name Server (iSNS) for discovery
•
iSCSI initiator access control management using discovery domains and a discovery domain set
•
Session management, such as session tracking and performance monitoring
•
Session authentication using CHAP
NOTE:
The HP StorageWorks B-Series iSCSI Director Blade gateway service is not compatible with other
iSCSI gateway platforms, including Brocade iSCSI Gateway or the Brocade Multiprotocol Router.
iSCSI session translation
The iSCSI gateway enables applications on an IP network to use an iSCSI initiator to connect to FC targets.
The iSCSI gateway translates iSCSI protocol to Fibre Channel Protocol (FCP), bridging the IP network and
FC SAN.
Figure 33
shows a basic implementation.
Figure 33
iSCSI gateway service basic implementation
The HP StorageWorks B-Series iSCSI Director Blade acts as an iSCSI gateway between FC-attached targets
and iSCSI initiators. On the iSCSI initiator, iSCSI is mapped between the SCSI driver and the TCP/IP stack.
