Figure 7: An example of Ethernet connections using interface pairs
51 Interface pair from data ports eth3aHost/server
2 6Switch 1/subnet 1 Interface pair from data ports eth3b
73 Data interface pair 1Switch 2/subnet 2
4 8Array Data interface pair 2
An interface pair is the combination of the same data port on both controllers. In the preceding diagram:
• Data ports eth3a form one interface pair (green)
• Data ports eth3b form another interface pair (blue)
Make sure that each interface pair connects to the SAME network or subnet. In this example, the red interface pair connects
to subnet 1 and the blue connects to subnet 2.
Fibre Channel Interface Pairs
A Fibre Channel interface pair refers to a set of two Fibre Channel data connections, one from each controller, to the Fibre
Channel switch. The cables for an interface pair connect to the same data port on each controller. See Interface Numbering
on page 17.
