The RAID chassis can use port 0 of each controller as one failover pair, and port 1 of each controller as a
second failover pair. Port 0 of each controller must be in the same subnet, and port 1 of each controller must
be in second subnet.
For example (with a netmask of 255.255.255.0):
l
Controller A port 0: 10.10.10.100
l
Controller A port 1: 10.11.10.120
l
Controller B port 0: 10.10.10.110
l
Controller B port 1: 10.11.10.130
In addition to setting the port-specific options described above, you can view settings using the GUI.

If using the V3 disk management utility, in the System topic, select Action > Set Up Host Ports.
o
The Host Ports Settings panel opens, allowing you to access host connection settings.
l
If using V2 disk management utility, in the Configuration View panel, right-click the system and select
Configuration > System Settings > Host Interfaces.
o
The Configure Host Interface panel opens, allowing you to access host connection settings.

iSCSI Considerations
When installing a QXS-4 or QXS-6 Series 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
The RAID chassis can use port 2 of each controller as one failover pair, and port 3 of each controller as a
second failover pair for the iSCSI traffic. Port 2 of each controller must be in the same subnet, and port 3 of
each controller must be in second subnet.
For example (with a netmask of 255.255.255.0):
l
Controller A port 2: 10.10.10.100
l
Controller A port 3: 10.11.10.120
l
Controller B port 2: 10.10.10.110
l
Controller B port 3: 10.11.10.130
