Using Ultra320/160 Hard Disk Drives; Using Scsi Devices - IBM Adaptec Ultra320 SCSI User Manual

Using Ultra320/160 Hard Disk Drives

We recommend keeping your LVD (Ultra 320, Ultra160 and
Ultra2) SCSI devices separate from your non-LVD SCSI devices.
If you combine LVD and non-LVD SCSI devices on the same
SCSI channel, the data transfer rate of the LVD SCSI devices will
drop down to non-LVD SCSI performance levels of up to
40 MB/sec.

Internal LVD SCSI devices come from the factory with
termination disabled and cannot be changed. Proper
termination is provided by the terminator at the end of the
internal LVD SCSI cable.

Using SCSI Devices

If you connect SCSI devices (such as scanners, tape drives, zip
drives, etc.) to your Adaptec SCSI Card 29320ALP, you must install
the device manufacturer's proprietary software drivers. See your
device's documentation for details.
