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 cable connections degrades the

controller performance.

Configuring SCSI Devices

When configuring devices for Adaptec 2000S, 2005S, 2100S, 2110S,

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.

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.

Wide devices allow data to be transferred at twice the rate of

Narrow devices. The Wide bus is backward compatible with

Narrow devices, allowing both types of SCSI devices to be used with

the same controller. The Narrow interface is still used with some

SCSI devices, such as tape and CD drives.
