Upgrading Your Server 9-7

SCSI ID / SAS Port

The hard disk drive bay may contain up to six hard disk drives. The SCSI IDs or SAS port numbers are factory-assigned to hard disk drives as shown below.

SCSI ID 0

SAS Port 0

SCSI ID 1

SAS Port 1

SCSI ID 3

SAS Port 3

SCSI ID2

SCSI ID 5

SCSI ID 4

SAS Port 2

SAS Port 5

SAS Port 4

 

The hard disk drive bays are connected to the SCSI connector on the mother board when the server is shipped. To use the hard disk drives in a disk array configuration, run the SCSI BIOS utility (see Chapter 4). If you have an optional RAID controller, install it to your server and reconnect the cable from the connector on the mother board to the RAID controller connector. For the cable reconnection, see "Disk Array Controller".

A dummy block is installed in the hard disk drive bays except the one with SCSI ID0 or SAS Port 0 defined. The purpose of a dummy block is to increase the cooling effect in the server. Install a dummy block in slots not containing a hard disk drive.
