SAS Backplane Boards
There are two SAS backplane board options, one supporting up to five 3.5-inch drives, and the other
supporting up to eight 2.5-inch drives. For the 2.5-inch option only, an additional board, the peripheral
interposer board, provides some of the connectors (see "Peripheral Interposer Board Connectors"
on page 17).
