The server supports single- or dual-channel hard drive configurations. The single-channel configuration (simplex) supports up to six hard drives on one channel. The dual-channel configuration (duplex) supports two hard drives on one channel (SCSI IDs 0 and 1) and up to four hard drives on the other channel (SCSI IDs 2 through 5).
The SCSI IDs for both simplex and duplex configurations are illustrated. Always populate hard drive bays starting with the lowest SCSI ID.
