Blade overview
The B-series iSCSI Director Blade provides IP hosts access to Fibre Channel storage devices. The IP
host sends SCSI commands encapsulated in iSCSI PDUs to a blade port over TCP/IP. The PDUs are
routed from the IP network to the Fibre Channel network and then forwarded to the target.
Figure 142 shows a sample configuration in which a B-series iSCSI Director Blade bridges an IP
network and Fibre Channel network.

.
The incoming iSCSI initiators on an iSCSI port are mapped as a single iSCSI virtual initiator. The
virtual initiator is presented to Fibre Channel targets as an N_Port Fibre Channel initiator device with
a WWN.
By default, the blade uses basic LUN mapping to map Fibre Channel targets to iSCSI virtual targets.
This creates one iSCSI virtual target per Fibre Channel target and allows 1-to-1 mapping. The iSCSI
initiators are then allowed to access the iSCSI virtual targets.
