2 SCSI is a key technology for storage
SCSI is a serial communications technology designed to transfer large amounts of data between a
variety of hardware systems over long distances. It is a key technology for applications that require
shared, high bandwidth access to storage.
SCSI provides a logical point-to point serial channel for the transfer of data between a buffer at a source
device and a buffer at a destination device. It moves buffer contents from one port to another, without
regard to the format or meaning of the data so different upper level protocols are able to run over SCSI
hardware.
The SCSI architecture is structured as a hierarchical set of protocol layers. Defined within these layers
are rules for signal interfaces, serial encoding and decoding, error control, frame format and
communications protocols.
ATTO Express PCI SCSI host adapters carry SCSI protocol over SCSI.

3.1 Determining cabling and termination
Cables and devices must be chosen to maximize performance and minimize the electrical noise from the
high-speed data transfers available with the SCSI protocol. Cabling and termination methods become
important considerations for proper performance. SCSI cables and devices are subject to specific length
and number limitations to deal with electrical problems that arise at increased operating speeds.
ATTO ExpressPCI Ultra3 SCSI host adapters will
operate with both Low Voltage Differential and
Single-Ended devices.
When connected to Ultra 3 devices, the ATTO
ExpressPCI Ultra3 SCSI host adapters will
negotiate to Ultra 3 transfer rates of 160 MB/sec.
per channel.
When connected to Single-Ended devices, the
ATTO ExpressPCI Ultra3 SCSI host adapters will
negotiate to Ultra3 transfer rates of 40 MB/sec.
per channel.
Cable types
Single-ended and differential SCSI host adapters
use the same cables. Use high quality cables rated
for the type of SCSI transfers required: wellinsulated SCSI cables ensure error free
communications. Try to keep cable lengths as
short as possible to ensure higher signal quality
and performance.
Examples
The SCSI specification limits total bus cable
length for Single-Ended SCSI in a non-UltraSCSI
environment to 3 meters (combined length of both
internal and external cable lengths).
In an UltraSCSI workgroup environment with a 7drive tower, you are limited to 1.5 meters between
the host and the tower, including the cabling for
the tower. If the 7-drive tower requires 1 meter of
cabling to connect all of its drives, the distance
from the tower to the host must be .5 meters.
UltraSCSI is very sensitive to SCSI bus noise,
cable distances and the number of devices
connected on the SCSI bus. Carefully connect
your devices when working with UltraSCSI.
Ultra3SCSI and Ultra2 SCSI are less sensitive to
bus noise and offer you the ability to connect a full
load of devices up to 12 meters.

Please refer to the documentation you received
Termination
The SCSI bus is a chain of SCSI devices. The
devices at both ends of any SCSI chain must be
terminated for the SCSI bus to function correctly.
A SCSI device chain can be configured in three
different ways: internal, external and an
internal/external SCSI device chain.
The ATTO ExpressPCI SCSI adapter is a SCSI
device and may require termination depending
upon the configuration. Be sure to use the correct
terminator. Single-Ended, Low Voltage
Differential and Differential SCSI busses use
different types of terminators that should not be
mixed.
Single-Ended and LVD signaling The
ExpressPCI Ultra3 SCSI host adapter supports
two types of SCSI signaling: Low Voltage
Differential (LVD) and Single-Ended. Ultra2 and
Ultra3 SCSI require LVD signaling for optimal
performance. UltraSCSI and slower devices use
Single-Ended signaling. Devices on the same
SCSI bus must use the same signaling, either LVD
or Single-Ended.
SCSI terminators used with Ultra3
SCSI host adapters must match the SCSI bus
signal. When using only LVD devices an LVD
terminator should be used. A Single-Ended
terminator with LVD devices usually works, but
all devices will be limited to Ultra SCSI speeds,
instead of Ultra2 or Ultra3 speeds. Single-Ended
devices require a Single-Ended terminator. If you
use an LVD terminator with Single-Ended
devices, the system may hang or devices will not
be seen on the SCSI bus. Some termination
manufacturers provide terminators which
automatically sense Single-Ended or LVD
termination.
Internal and external termination External
terminators should be attached to the last external
device in the SCSI chain. Be careful not to provide
any other termination on the external SCSI chain.
(Extra termination will cause a loss in signal
quality.) The last device on an internal SCSI chain
should also be terminated. Many Single-Ended
Ultra SCSI and earlier devices provide a jumper
setting for applying termination, in which case the
last device on the internal cable should have a
Terminators
8
jumper placed over the pins designated for
supplying termination. Check with your drive
manufacturer if you are not sure which pins to
use.
LVD Ultra2 and Ultra3 SCSI devices are not
capable of supplying their own termination.
Instead, termination must be supplied by an
outside source, usually an internal ribbon cable
which has a SCSI terminator attached to the end.
Connect the non-terminated end of the cable to
the host adapter card and the internal drives to the
subsequent connectors. The terminator should be
at the opposite end of the cable from the host
adapter card.
Mixing Wide and Narrow devices Wide (16-bit)
and Narrow (8-bit) devices can be connected
together on the same connector of the host adapter
card, but Wide devices must be attached first in
the chain, followed by Narrow devices. The cable
or adapter used to convert from a wide (68-pin)
connector to a narrow (50-pin) connector must
provide partial termination to allow the upper 8bits (or byte) of the Wide SCSI bus to be properly
terminated. A Narrow terminator should then be
used on the last Narrow device to terminate the
rest of the SCSI bus. A SCSI bus without partial
termination between the Wide and Narrow
devices may appear to work correctly, but
occasional I/O errors will occur without proper
termination.
Using internal and external connectors on
UL3D/UL3D-66 The UL3D/UL3D-66 has two
connector and an external connector. Devices can
be attached to both connectors on the same bus.
However, the host adapter card will run with
Single-Ended signaling at UltraSCSI speeds if
Single-Ended and LVD devices are on the same
bus, even if using different connectors.
Automatic termination: when both internal and
external connectors are used, the host adapter card
detects the presence of devices and turns off
termination. If devices are removed from one
connector of the card, the host adapter will
automatically detect the change and enable its
own termination.
Software controlled termination: You may have
to override the host adapter’s automatic
termination if only narrow devices are attached to
one connector and wide devices are attached to
the other connector on the same bus. The host
adapter must supply partial termination to the
upper 8-bits (byte), but it will not do so
automatically. Please refer to your ExpressPCI
Utilities manual to set the host adapter’s
termination to Upper Byte.
Termination power: host adapters supply
termination power to the bus at all times and many
SCSI devices are also able to supply termination
power. SCSI signal quality, particularly with long
or marginal quality cables, may be improved if the
device supplies the termination power. Contact
your device manufacturer for more information
on your device’s ability to supply termination
power.

4 Maximizing Performance with ExpressPCI HBA
If you are getting less performance than you expect, there are several things you can do such as making
sure you are using the latest ATTO driver, setting the registry entry for large block transfers, using ATTO
ExpressRAID for setting up RAID groups, increasing transfer size, and analyzing your system’s I/Os.
While the factory settings on your ExpressPCI
host adapter should provide excellent
performance for a wide range of applications, you
may improve performance by modifying some of
the system factors which affect your ExpressPCI
host adapter.
For example, the ATTO driver can transfer well
over a megabyte with one SCSI command.
NOTE You must use an ATTO driver when using ATTO
ExpressRAID software.
Use the latest ATTO driver
Determine which drive is currently in use, then
install the latest ATTO driver found at
www.attotech.com.

driver or disable it using the Devices applet.
If the system has a built in Symbios or LSI
adapter, do not disable the driver for that
adapter.

3
Either remove the previously-installed
driver or disable it using the Devices applet.
If the system has a built in Symbios or LSI
adapter, do not disable the driver for that
adapter.
Set registry for large block transfers
If your application requires large block transfers,
set the registry entry correctly for the
MaximumSGList keyword. Several files supplied
with the device driver download package can set
this value to any one of the following sizes: 64Kb,
128KB, 256Kb, 512KB, 1MB and NT default
(64KB). The files are ASCII text files and can be
viewed with any suitable editor. The files also
explain the registry setting and how to change the
setting.
The ExpressPCI adapter can have a maximum
transfer size from 64KB to 1MB. If the registry
value is set to a number higher than 0xff, the
driver will reduce the setting to 0xff. The driver
installation process will set the default value to
0xff.
Set up RAID groups with ATTO
ExpressRAID
Instead of using the RAID functionality built into
Windows OS, use the ATTO ExpressRAID
software for the most efficient performance.
ATTO ExpressRAID requires one less level of
driver through which commands must pass and
fewer commands are required to pass through the
driver hierarchy.
Other advantages of ATTO ExpressRAID
striping:
❖ You can boot your system off striped drives
❖ Stripe sets created with ExpressRAID are
recognizable by DOS and Windows
❖ You can stripe removable-media drives with
ExpressRAID.
If you have purchased the striping option,

15 TTO Technology ExpressPCI Ultra3 SCSI Host Adapters Installation and Operation Manual
Increase transfer size
If you are writing to an application that uses a lot
of sequential disk I/O to a contiguous area on
disk, you should use as large a transfer size as
possible to reduce overhead on the system, on the
SCSI bus and within disk drives.
Analyze your I/Os
For large sequential data transfers, use Direct I/O
by selecting FILE_FLAG_WRITE_THROUGH
and FILE_FLAG_NO_BUFFERING flags with
your CreateFile call to avoid the overhead of
copying data from one area of memory to another,
to reduce the number of SCSI commands which
must be executed and to leave system pages
available for other data.
If your application requires a small number of
I/Os and the transfers are rather small, however,
you may get better performance by letting the
system cache your data in the system pages.
You might want to use over-lapped I/O using the
FILE_FLAG_OVERLAPPED option with the
CreateFile call. Overlapped I/O allows the
application to send many commands to the device
at once.
The ATTO Disk Benchmark program, included
with the ExpressPCI Utilities on the CD shipped
with your ExpressPCI adapter, shows the effect of
using the above I/O modes.
❖ If you turn off Direct I/O and set the file size
to a value significantly less than the amount
of memory in your computer, you will get
some artificially high transfer rates because
very little I/O is actually being performed by
the SCSI device: all the activity is involved in
transferring data between the application and
the system pages.
❖ As you increase the file size to a value more
than the amount of memory in your computer,
you will see marked performance
degradation.
❖ If you turn on Direct I/O, you can see the
effect of removing the system pages from the
overhead picture.
❖ If you use overlapped I/O, you will see
performance improvements in the low to
medium transfer sizes.
❖ However, depending on the amount of
memory in your computer, you may not be
able to use queue depths greater than 4 or 5.

5 Troubleshooting
This chapter contains solutions for the most common problems you might encounter. If you need
additional assistance, please refer to the ATTO Technology web site (www.attotech.com) or contact an
ATTO Technology authorized representative.
9Check each cable connection on every device.
Verify all cables are in proper working condition.
Loose or broken cables are often the cause of
errors or problems.
9If the same device shows up at several
different SCSI IDs, either its SCSI ID is set the
same as the ATTO ExpressPCI SCSI ID, or the
cable is defective.
9Check that your SCSI devices are plugged
into an AC outlet and are turned on before you add
power to your computer.
9If a device doesn’t appear and cables and
termination are set properly, try lengthening the
SCSI Reset Delay using the ExpressPCI Utilities
found on the CD that came with your host adapter.
9Verity that all devices and busses are properly
terminated. See Chapter 3.1 for more
information.
9Verify that all devices attached to the ATTO
ExpressPCI SCSI adapter have unique SCSI IDs.
ATTO ExpressPCI SCSI adapters have a default
SCSI ID of 7.
9PC users should make sure that SCSI adapter
firmware and Windows drivers are at the same
revision level. Unless indicated otherwise, the
latest drivers and firmware can be downloaded
from the ATTO Technology website
