SCSI Addresses
The SCSI ID assigned to a hard drive is determined by its position in the drive
cage. The SAF-TE chassis management processor is assigned SCSI ID 5. The

NOTE
Do not use hard drives that are not specifically certified by
Hewlett-Packard for use in the HP Rack Storage/12.
The hard drives are multimode disk drives, which allow the integration of the
differential drivers and receivers into SCSI drive controllers. The hard drive
technology provides increased signal quality, and ensures the same data integrity
as the previous high voltage differential designs at a reduced cost.
The HP Rack Storage/12 hot-swap hard drives come in two heights: the 1-inch
low-profile drive and the 1.6-inch half-height drive.
