QXS-312 and QXS-324 iSCSI Considerations

When installing a QXS-312 or QXS-324 iSCSI RAID chassis, use at least three ports per server—two for
the storage LAN, and one of more for the public LAN(s)—to ensure that the storage network is isolated from
the other networks. The storage LAN is the network connecting the servers—via switch attach—to the
RAID chassis.

IP address scheme for the controller pair — two iSCSI ports per controller
