Step 8 - Connecting the Ethernet Cables
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.
Things to Know – Connecting Ethernet Cables
ATTENTION 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.
„
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 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.
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.
