Filling empty drive bays

Empty drive bays in the server must be filled by empty drive carriers or empty drive trays, as appropriate. With the bezel removed, install the appropriate carrier, then replace the bezel by snapping it into place on the front of the server. Empty drive carriers for unused drive bays are included with your server.

Configuring your onboard RAID solutions

Your server comes equipped with an onboard, chipset SCSI RAID solution, which supports RAID levels 0 (striping) and 1 (mirroring). The onboard RAID solutions can be enabled in the BIOS (page 154) and configured by launching the appropriate RAID BIOS console during the boot process.
