The following figure shows storage array management connections from the
controller tray or controller-drive tray to the Ethernet. In this topology, you must
install a network interface card (NIC) in the storage management station in which the
client software resides. For dual controllers, you must install two NICs in the storage
management station.
NOTE For more information about NICs, see
Figure 1 Network Out-of-Band Ethernet Topology
NOTE In limited situations where the storage management station is connected
directly to the controller tray or the controller-drive tray, you must use an Ethernet
crossover cable to connect the storage management station to the Ethernet port. An
Ethernet crossover cable is a special cable that reverses the pin contacts between the
two ends of the cable.
