Guidelines for Making Changes to Current Installation

Drive Considerations

If you will be installing or replacing drives in your Compaq server, keep in
mind that:
Drives may be Fast-SCSI-2, Fast-Wide SCSI-2, Wide-Ultra SCSI, or a mixture
of the three in servers and storage systems supporting hot-pluggable drives.
Drives should not contain termination. Compaq servers and internal
cabling provide the required termination of the SCSI bus.
Compaq hard drives supported by the SMART-2DH Controller
include:
1.05-GB Fast-SCSI-2
2.1-GB Fast-SCSI-2
2.1-GB Fast-Wide SCSI-2
2.1-GB Wide-Ultra SCSI
4.3-GB Fast-SCSI-2
4.3-GB Fast-Wide SCSI-2
4.3-GB Wide-Ultra SCSI
9.1-GB Wide-Ultra SCSI
9.1-GB Fast-SCSI-2
18.2-GB Wide-Ultra SCSI 3
Drives should be of the same capacity to provide the greatest storage space
efficiency when grouped together into the same drive array.
Except on hot-plug drives in ProLiant servers and storage systems, you must
manually set the SCSI ID on each drive to a unique value in the range of 0 to
6 for each SCSI bus. Consult the documentation that came with the drive for
instructions on setting the SCSI ID.

Determining the Maximum Storage

Maximum storage capacity factors of a server include:
subtract any option slots used for other purposes
available internal drive bays
availability of external connectors for SCSI Bus 1 (requires connector
panel location or vacant option slot)
