Adaptec RAID Installation Guide
ATA cables
ATA RAID controllers use ATA/100 cables. The cables supplied
with your controller kit have a blue connector at one end and a
black connector at the other end. Plug the blue connector into the
controller and the black connector into the hard drive.
Caution:
Reversing the connection degrades the controller
performance.
configuring SCSI devices
When configuring devices for Adaptec 2100S, 3200S, 3210S,
3400S, and 3410S controllers, you may need to
■
Decide how to position drives on the SCSI bus.
■
Select cables.
■
Enable or disable SCSI termination.
■
Set the SCSI IDs.
Note:
SCSI drives should, in general, not be reformatted.
However, if your SCSI drive was formatted to a sector
size other than 512 bytes, you must reformat the drive
before you can use it in a RAID. Refer to the
Adaptec
Storage Management Software User’s Guide
for details.
In general, RAID drives should be as alike as possible in terms of
capacity and performance.
narrow and wide SCSI devices
You can attach either Narrow (8-bit) or Wide (16-bit) SCSI
devices to your Adaptec SCSI controller. If you use Narrow and
Wide devices on the same Wide cable, put one of the Wide devices
at the end of the cable. This ensures that the 16-bit signals are
correctly terminated.
