B-series MP Router and iSCSI
The B-series MP Router offers Fibre Channel routing, FCIP SAN extension functionality, and
iSCSI-to-Fibre Channel bridging capability.
Hardware support
This section describes the hardware devices supported by the B-series MP Router for iSCSI.
Fibre Channel switches
The MP Router iSCSI mode supports any B-series switch in an MP Router backbone fabric.
The MP Router backbone fabric consists of at least one MP Router and includes all other routers
and B-series switches connected to the MP Router through E_Ports. iSCSI initiators connected to
the MP Router's iSCSI ports can only access storage connected to the MP Router backbone fabric
(“iSCSI storage device connectivity for the MP Router” (page 116)).
Edge fabrics consist of all Fibre Channel switches and their attached storage connected to the MP
Router through EX_Ports. Edge fabrics are not accessible to iSCSI initiators connected to the MP
Router's iSCSI ports (“Fibre Channel routing storage device connectivity for the MP Router”
(page 117)).
Storage systems
MP Router iSCSI devices must connect directly to the backbone fabric of the router. The supported
arrays are as follows:
• XP storage systems
Software support
MP Router iSCSI supports single-path devices only. Multipath software is not supported.
