Each controller has 4 SAS ports (laid out as 2 pairs). Standard Data Domain systems,
and systems with the licensed HA feature only use ports 0 and 2 on each controller.
Ports 1 and 3 typically have a plastic plug blocking the unused ports to make inserting
a cable into the correct ports easier.
Please refer to Installing the Shelves on page 17 chapter for details about cabling.
The Cabling shelves on page 24 section provides the needed details.
