Installing System Components
The system board holds the system's control circuitry and other electronic
components. The processors and memory modules are installed on the system
board, and on the optional processor expansion module (PEM).
The hard-drive bays provide space for up to eight optional 2.5-inch hard
drives or five optional 3.5-inch SAS hard drives. The hard drives connect to a
SAS controller card or an optional battery-cached SAS RAID controller card
through a SAS backplane. A removable drive carrier supports an optional
optical drive.
