External SCSI Expansion

External SCSI devices, such as tabletop or rackmounted storage devices, can be connected
to the system using EISA- or PCI-based SCSI adapters. Use the following rules to
determine if a particular device can be used:
•
The device must be supported by the Windows NT. Consult the software product
description for the device or contact the hardware vendor.
•
A maximum of seven devices can be attached on any one SCSI controller.
•
Each device on the bus must have a unique SCSI ID. You may need to change a
device's default SCSI ID in order to make it unique. For information about setting a
device's ID, refer to the guide for that device.
•
The entire SCSI bus length, from terminator to terminator, must not exceed 6 meters
for fast double-ended SCSI, or 3 meters for fast single-ended SCSI.
•
Ensure that the SCSI bus is properly terminated and that no devices in the middle of
the bus are terminated.
•
For best performance, wide devices should be operated in wide SCSI mode.
