Post Installation Tasks 45
• For redundancy in a dual controller (duplex) configuration, ensure each
host network interface is configured to connect to both storage array
controllers.
• For optimal load balancing, ensure each host network interface that is used
for iSCSI traffic is configured to connect to each storage array controller.
• It is recommended that each host network interface only establishes one
iSCSI session per storage array controller.
NOTE: The utility tries to follow the guidelines for the host connectivity whenever
possible based on the available host network interfaces and their connectivity with
the iSCSI host ports of the storage array.
