Overview

Ultra160 SCSI on the Adaptec SCSI Card 39160

The Adaptec SCSI Card 39160 enables you to connect up to 30 SCSI
devices—such as very large arrays of high-performance HDDs,
external storage subsystems, clustered configurations, Ultra160 hard
disk drives, scanners, and CD-ROM drives—to any Intel-based com­puter with 64- or 32-bit PCI expansion slots. Ultra160 is a new gener­ation of SCSI tec hnology that increases SCSI performance from
80 MBytes/sec to 160 MBytes/sec. In addition to providing much
greater performance, Ultra160 SCSI enables a maximum allowable
cable length of 12 meters for optimal connectivity and flexibility.

The Adaptec SCSI Card 39160 has two independent SCSI channels,
each with a maximum throughput of 160 MBytes/sec.

Understanding SCSI

SCSI (pronounced “scuzzy”) stands for Small Computer Systems
Interface. SCSI is an industry standard computer interface for con­necting SCSI devices (such as a hard disk drive, CD-ROM drive, or
scanner) to a common SCSI bus.

A SCSI bus is an electrical pathway that consists of a SCSI adapter
card (such as the Adaptec SCSI Card 39160) installed in a computer
and one or more SCSI devices. SCSI cables are used to connect the
devices to the SCSI adapter card. The Adaptec SCSI Card 39160 has
two independent SCSI buses (channels).

For the SCSI bus to function properly, a unique SCSI ID must be
assigned to the SCSI card and each SCSI device connected to it, and
the SCSI bus must be properly terminated.

2

Overview

SCSI IDs

Each device attached to the Adaptec SCSI Card 39160, as well as the
Adaptec SCSI Card 39160 itself, must be assigned a un ique SCSI ID
number from 0 to 15 for each of the two SCSI buses. A SCSI ID
uniquely identifies each SCSI device on the SCSI bus and determines
priority when two or more devices are trying to use the SCSI bus at
the same time.

Refer to the device’s documentation to set the SCSI ID. Here are
some general guidelines for SCSI IDs:

■

For internal SCSI devices, the SCSI ID usually is set by config­uring a jumper on the device.

■

For external SCSI devices, the SCSI ID usually is set with a
switch on the back of the device.

■

SCSI ID numbers do not need to be sequential, as long as the
Adaptec SCSI Card 39160 and each device has a different num­ber. For example, on each of the two SCSI buses you can have
an internal SCSI device with ID 0, and an external SCSI device
with ID 6.

■

SCSI ID 7 has the highest priority on the SCSI bus. The priority
of the remaining IDs, in descending order, is 6 to 0, then 15 to 8.

■

On both SCSI buses (channels ) th e Adaptec SCSI Card 39160 is
preset to SCSI ID 7 and should not be changed. This gives the
card the highest priority on the SCSI bus.

■

Most internal SCSI hard disk drives come from the factory pre­set to SCSI ID 0.

■

If you have 8-bit (or Narrow) SCSI devices, the y must use SCSI
IDs 0, 1, 2, 3, 4, 5, or 6. SCSI ID 0 is recommended for the first
SCSI hard disk drive.

■

If you are booting your computer from a SCSI hard disk drive
connected to the Adaptec SCSI Card 39160, the Boot SCSI ID
setting in the SCSI

Select

utility must correspond to the SCSI ID
of the device from which you are booting. By default, the Boot
SCSI ID is set to 0. We recommend that you do not change this
setting.

■

In Windows® 95/98, you can use the Device Manager to deter­mine which SCSI ID is assigned to each installed SCSI device.

Adaptec SCSI Card 39160 User’s Reference

Terminating the SCSI Bus

To ensure reliable communication on the SCSI bus, the ends of the
SCSI bus must be properly terminated. This is accomplished when
the device at the end of each cable, or the end o f the cable itself, has a
terminator installed (or enabled). Terminators must be removed, or
termination must be disabled, on devices between the ends of each
cable.

Since the method for terminating a SCSI device can vary widely,
refer to the device’s documentation for instructions on how to
enable or disable termination. Here are some general guidelines for
termination:

■

Internal Ultra160 and Ultra2 SCSI devices come from the fac­tory with termination disabled and cannot be changed. Proper
termination for these internal devices is provided by the built­in terminator at the end of the 68-pin internal LVD SCSI cable.

■

Termination on Wide SCSI, Narrow SCSI, and Ultra SCSI
devices usually is controlled by manually setting a jumper or a
switch on the device, or by physically removing or installing
one or more resistor modules on the device.

■

Termination on most external SCSI devices is controlled by
installing or removing a SCSI terminator. However, termina­tion on some external SCSI devices is enabled or disabled by
setting a switch on the back of the SCSI device.

■

By default, termination on the Adaptec SCSI Card 39160 itself
is set to

Automatic

(the preferr ed m ethod). We recommend that

you do not change this default setting.

Using the Adaptec SCSI Card 39160 and SCSI Devices

Combining SCSI and Non-SCSI Devices

You can install the Adaptec SCSI Card 39160 in a computer that
already has a non-SCSI controller, such as an EIDE controller. How­ever, you cannot cross-connect the disk drives and other devices:
SCSI devices must be connected to the Adaptec SCSI Card 39160,
EIDE devices must be connected to the EIDE controller, and so on.

When you install the Adaptec SCSI Card 39160 and SCSI disk drives
in a computer that boots from a non-SCSI disk drive, the computer
will continue to boot from the non-SCSI disk drive unless you
change the computer’s CMOS configuration. You do not need to
change the configuration if you just want to use the SCSI drives for
additional file storage space.

If your computer’s motherboard BIOS supports the BIOS Boot Spec­ification (BBS) feature, you can select a dif fer en t boot device without
much difficulty. (To determine if the motherboard BIOS supports
BBS, read the computer documentation or contact your mother­board manufacturer.)

Installing Multiple SCSI Cards

■

You can install multiple SCSI cards in your computer; you are
limited only by the available system resources (for example,
IRQ settings, I/O port addresses, BIOS addresses, and so
forth).

■

Each SCSI card you install forms a separate SCSI bus with a
different set of SCSI devices. SCSI IDs can be reused as long as
the ID is assigned to a device on a different SCSI card (for
example, each SCSI card can have a device with SCSI ID 2).

■

If you have two or more SCSI cards and your computer boots
from a SCSI disk drive, leave the host adapter BIOS enabled on
the SCSI card to which the boot disk drive is connected. Use

Select

Connecting SCSI Devices

Connecting SCSI Devices

Here are some examples of how you can connect internal and exter­nal SCSI devices to the Adaptec SCSI Card 39160. To achieve maxi­mum performance, attach the first device to the end connector of the
cable (furthest from the SCSI card); attach other devices to the con­nectors that are closer to the SCSI card.

The first example shows Ultra160 and Ultra2 SCSI devices con­nected to internal and external SCSI connectors of both SCSI
channels. Note the built-in terminators at the end of the internal
LVD SCSI cables. The last external SCSI device on each SCSI channel
must be terminated with an LVD/SE terminator plug to ensure that
all devices will operate at their maximum speed.
