Introduction
The Compaq RA4000 supports these Compaq hot-pluggable drives:
n 1.6-inch Fast SCSI-2
n 1.6-inch Fast-Wide SCSI-2
n 1.6-inch Wide-Ultra SCSI-3
n 1-inch Fast SCSI-2
n 1-inch Fast-Wide SCSI-2

The RA4000 accepts both 1-inch and 1.6-inch standard height drives. The
drives must be mounted on Compaq hot-pluggable drive trays. SCSI IDs are
assigned automatically according to the drive location, allowing 1-inch and
1.6-inch drives to be intermixed easily.
The maximum number of drives that can be installed in the Compaq RA4000
is shown in the table below.
Both the 1-inch and 6-inch hard drives can be intermixed when installed in the
Compaq RA4000. To optimize capacity when intermixing drives, refer to the shadow
markings on the faceplate for appropriate 1-inch and 6-inch drive positions.
1-inch 12
1.6-inch 8
