Connecting Controller Enclosures to Expansion
Enclosures
A controller enclosure uses Controller A and Controller B expansion ports to connect
to FC-AL ports at the back of an expansion enclosure (
FIGURE 3-5
).

Controller Enclosure and Expansion Enclosure Ports
The controller enclosures and the expansion enclosures connect with a pair of Active
Copper cables. These copper cables have transceiver electronics built into their
connector ends. They plug directly into the SFP ports of the controllers and expansion
enclosures.
Note – This section contains instructions for connecting controller enclosures and
expansion enclosures. These instructions apply to one controller enclosure or to two
controller enclosures. If you are using two controller enclosures, follow the same
instructions to connect expansion enclosures to
each controller enclosure.
Caution – One array can contain Fibre Channel disk drives in the controller
enclosure and expansion enclosures, and the other array can contain SATA disk
drives in the expansion enclosures only. However, you cannot mix EU F (Fibre
Channel) and EU S (SATA) expansion enclosures attached to a controller enclosure.
Note – A maximum of seven EU F or eight EU S expansion enclosures can be
attached to a controller enclosure.
