2 SCSI is a key technology for storage
SCSI is a serial communications technology des igned to transfer large amounts of dat a between a
variety of hardware systems over long distances. It is a key technology for applications that require
shared, high bandwidth access to stor age.
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
The SCSI architecture is structured as a
hierarchic al set of proto col layers. Def ined within
these layers are rules for signal interfaces, serial
encoding and decoding, error control, frame
format and communications protocols.

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 tra ns fers 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 spee ds .
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: we llinsulated SCSI cables ensure error free
communications. Try to keep cable lengths as
short as possible to ensure higher signal quality
and performanc e .

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.

Please refer to the documentation you received
with your SCSI devices to determine if your
device is Wide or Narrow.
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 dependi ng
upon the configuration. Be sure to use the correct
terminator. Single-Ended, Low Voltage
Differential and Differential SCSI buses use
different types of terminators that should not be
mixed.

attached a narrow (8 bit) device to the int ern al
WIDE (16 bit) connector and a WIDE (16 bit)
device to the external por t. You must manually
terminate the adapter using ATTO ExpressPCI
Utilities program with the termination option set
to Upper.
The ATTO ExpressPCI SCSI adapter only

To set up cabling and termination:
1 Determine whether your ATTO Express PCI
adapter is a single channel or dual channel
model. One external connector indicates a
single channel host adapter; two extern al
connectors indicate a dual channel host
adapter.
2 Determine if SCSI devices will be installed
internally or externally.
Total bus cable length,

any other termination on the external SCSI chain.
The last device on an internal SCSI chain should
also be terminated. This can be done in several
ways. Many Single-Ended Ultra SCSI and earlier
devices provide a jumper setting for applying
termination: place a jumper over the pins
designated for termination on the last device on
the internal cable. Check with y our drive
manufacturer if you are not sure which pins to
use.
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, followed by narrow devices.
To terminate the SCSI bus, the cable or adapter
used to convert from a wide (68-pin) connector to
a narrow (50-pin) connector provides partial
termination, allowing upper 8-bits (or byte) of the
wide SCSI bus to be pro perly terminated. A
narrow terminator should 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 at first
appear to work correctly , but occasional I/O errors
will occur without pro per termination.
NOTE
If you use both internal and e xternal connectors
and mix Single-Ended and L VD devices on the same bus,
even if using different connectors, the host adapter ca rd
will operate with Single-Ended signaling at UltraSCSI
speeds.
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 adapte r w ill
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 att ached to
the other connector on the same bus. The host
adapter must supply parti al 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.
9 ATTO Technology ExpressPCI Ultra/WIDE SCSI Host Adapters Installation and Operation Manual
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 pow er. Contact
your device manufacturer for more information
on your device’s ability to supply termination
power.

sure you are using the latest ATT O driver , setting the registry entry for large block transfers, using ATTO
ExpressRAID for setting up RAI D 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 A TT O
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.
Windows NT

4Examine the Driver tab for your SCSI
adapter. If the driver is not express.sys,
install the express.sys driver.
5 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.
Windows 2000 and XP

2Examine the Driver tab for your SCSI
adapter. If the driver is not express.sys,
install the express.sys driver.
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 corr ectly 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 edit or. 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 wi th Ex p ress R AID are
recognizable by DOS an d Windows
❖
You can stripe removable-media drives with
ExpressRAID.
If you have purchas ed the striping option,
additional informatio n about ExpressRAID is
15 ATTO Technology ExpressPCI Ultra/WIDE SCSI Host Adapters Installation and Operation Manual
available in the file
Stripe.txt
on the CD whic h has
been included with your ATTO ExpressPCI
adapters.
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 driv es.
Analyze your I/Os
For large sequential data transfers, use Direct I/O
by selecting
and
FILE_FLAG_NO_BUFFERING
CreateFile
your
FILE_FLAG_WRITE_THROUGH
flags with
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 us e ov e r-lapped I/O using the
FILE_FLAG_OVERLAPPED
CreateFile
call. Overlapped I/O allows the
option with the
application to send many commands to the device
at once.
The ATTO Disk Benchmark program, inclu ded
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 Dire ct I/O a nd s et th e 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 removi ng the sy stem 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 amoun t 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 m os t common problems you might encoun ter. If you need
additional assistance, please refer to the ATTO Technology web site (www.attotech.com) or contact an
ATTO Technology authorized representative.
9
Check 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.
9
Check that your SCSI devices are plugged
into an AC outlet and are turned on before you add
power to your computer.
9
Verity that all devices and busses are properly
terminated. See Chapter 3.1 for more
information.
9
Verify that all devices attached to the ATTO
ExpressPCI SCSI adapter have unique SCSI I Ds.
ATTO ExpressPCI SCSI adapters have a default
SCSI ID of 7.
9
If 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.
9
If 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.
9
PC users should make sure that SCSI adapter
firmware and Windows drivers are at the same
revision level. Unless indicated otherw ise, the
latest drivers and firmware can be downl oaded
from the ATTO Technology website
