9 Connecting the Ethernet Cables
9.1 Key Terms
in-band management
A method to manage a storage array in which a storage management station sends commands
to the storage array through the host input/output (I/O) connection to the controller.
out-of-band management
A method to manage a storage array in which a storage management station sends commands
to the storage array through the Ethernet connections on the controller.
9.2 Things to Know – Connecting Ethernet Cables
– These Ethernet connections are intended for out-of-band management and have nothing
to do with the iSCSI host interface cards (HICs), whether 1Gb/s or 10Gb/s.
Ethernet port 2 on each controller is reserved for access by your Customer and Technical
Support representative.
In limited situations in which the storage management station is connected directly to
the controller tray, you must use an Ethernet crossover cable. An Ethernet crossover
cable is a special cable that reverses the pin contacts between the two ends of the cable.
9.3 Procedure – Connecting Ethernet Cables
Perform these steps to connect Ethernet cables for out-of-band management. If you use only
in-band management, skip these steps.
1. Connect one end of an Ethernet cable into the Ethernet port 1 on controller A.
2. Connect the other end to the applicable network connection.
3. Repeat step 1 through step 2 for controller B.
NOTICE!
Risk of security breach
Connect the Ethernet ports on the controller tray to a private network segment behind a
firewall. If the Ethernet connection is not protected by a firewall, your storage array might be
at risk of being accessed from outside of your network.
