10 Connecting the ethernet cables
Use this chapter if you are using out-of-band management for your storage array. If you use in-
band management, you can ignore this chapter. To continue, see Connecting the power cords,
page 54.
10.1 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. The
SMagent must be installed for this method to work correctly.
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. This is the
recommended management method.
10.2 Things to know – connecting Ethernet cables
This topic concerns Ethernet management connections, not the Ethernet iSCSI connections
that might be used through a host interface card connection.
Notice!
Risk of security breach
Connect the Ethernet ports on the controller-drive 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.
Observe the following:
– Ethernet port 2 on each controller is reserved for access by Technical Support.
– Because the controllers support the Auto-MDIX feature, you do not need an Ethernet
crossover cable.
10.3 Procedure – connecting Ethernet cables
To connect Ethernet cables for out-of-band management:
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.
