1 SCSI is a key technology for storage
Ultra320 SCSI represents the seventh generation of SCSI technology, an I/O interface that increases
performance while maintaining backward compatibility and legacy support.
From its roots in 5 MB/sec. transfer rates, SCSI
has evolved as the leading interface for disk drive
connections in high performance servers. It
features maximum data transfer rates of 320
MB/second, full backward compatibility with
older versions of SCSI protocols and additional
features to improve performance and reliability.
Ultra320 is a powerful storage technology. All
forms of digital content, from e-mail, video, film,
and audio, to streaming video, and imaging, are
driving the unprecedented growth in storage that
pushes the I/O bandwidth, requiring more
advanced interfaces to handle data transfer.
SCSI advantages
• Backward compatible with older versions of
SCSI. Newer adapters will negotiate to the
lower speeds of legacy devices.
• Minimal investment to upgrade technology.
Older equipment may still be used with newer
equipment. Upgrade does not require
replacement of infrastructure.
Exhibit 1-1 How SCSI has evolved.

Asynchronous
Information
Protection
AIP: although most Ultra320traffic is sent synchronously and protected by CRC, some
information is still sent asynchronously. AIP implements CRC-level error checking on
asynchronous traffic ensuring end-to-end data integrity.
bit Smallest unit of data a computer can process: a single binary digit with a value of either 0 or 1
byte an ordered set of 8 bits
CRC Cyclic Redundancy Checking, an error-correcting code which calculates a numeric value for
received and transmitted data. If no error has occurred during transmission, the CRC for both
received and transmitted data should be the same.
destination address A value in the frame header of each frame which identifies the port in the node where the
frame is being sent
domain validation Before sending data, domain validation verifies that the physical connection is capable of
handling the negotiated transfer speed. If the system determines that Ultra320speeds are not
feasible, a slower speed is enforced.

SCSI is a key technology for storage
double transition
clocking
Increases the data line frequency to equal that of the request signal, allowing sampling on
both the leading and trailing edges of the request signal. Clocking can be set to ensure
compatibility with legacy devices.
flow control The target indicates to the initiator when the last packet of a data stream will be transferred so
that the initiator can flush FIFOs and terminate pre-fetch sooner than previously possible.
Basically, the target warns the initiator that the transfer is almost complete so that it can
prepare for the next transfer while the target completes the current transfer.
host A processor, usually a CPU and memory, which communicates with devices over an interface
HVD High voltage differential: uses two wires, transmitting a signal on one and its inverse on the
other. At the receiving end, the difference between the two signals is measured and
interpreted. Noise on the bus will affect both the signal and its inverse equally, so the
difference between the two lines will remain the same and the noise cannot be misread as a
signal.
initiator device A component which originates a command
LED Light-emitting diode: a type of diode that emits light when current passes through it. Visible
LEDs are used as indicator lights on all sorts of electronic devices.
LVD Low voltage differential. SCSI signalling method that combines the benefits of HVD and
single-ended technologies, allowing longer cabling configurations while consuming less
power than HVD technology.
originator An initiating device; a component which originates a command
packetization Creates information units (IUs) from commands, data, status information, etc. which are
passed as synchronous transfers. Maximizes bus use, minimizes command overhead and
allows multiple commands to be transferred in a single connection
pre-compensation Although SCSI transfer speeds have changed dramatically over the past several generations,
cable specifications have remained constant. Higher speed and frequency signals have a
greater potential for reflection and distortion over distance. Pre-compensation techniques
slightly modify the SCSI signal to reduce the chance of these types of problems.
Quick Arbitration
Select (QAS)
Arbitration
The process of devices negotiating for control of the bus with built-in “quiet times” so that fast
and legacy devices have an opportunity to take control of the bus. A fair, but somewhat
inefficient process, QAS speeds up the arbitration process by eliminating the bus free phase.
When combined with packetization, reduces command overhead and maximizes bus use.
read and write data
streaming
Minimizes data transfer overhead by allowing a target to send one data stream (LQ) packet
followed by multiple data packets. Minimizes overhead of data transfers because the target
can send one data stream packet followed by multiple data packets
receiver The ultimate destination of data transmission; a terminal device
SCSI Small Computer Systems Interface: a processor-independent standard for system-level
interface between a computer and intelligent devices including hard disks, floppy disks, CD-
ROM, printers, scanners, etc.
single-ended An electrical signal protocol that transmits information through changes in voltage. Single-
ended SCSI uses standard TTL signal and ground pairs to transmit information over the SCSI
bus.
training pattern SCSI is a parallel bus technology that is dependent on signals being transmitted on parallel
wires simultaneously. At higher speeds, minute differences in wire lengths and transmission
characteristics could cause problems. Training pattern testing measures these minute
differences and compensates for them.
Vpath™ Technology The ATTO ExpressPCI UL4S with Vpath Technology offers data transfer rates of 320
MB/sec. With one external connector and one internal connector, Vpath Technology allows
both faster and slower devices to run without impacting the speed of faster devices.

ATTO Technology Inc. ExpressPCI Host Adapter Installation and Operation Manual
3 Hardware installation
Install the ATTO ExpressPCI Ultra320 Host Adapter and attach your SCSI devices to it using the
instructions below. To get the best performance from your ATTO Express Ultra320 host adapters, use
Ultra 320 SCSI devices.
CAUTIONCAUTION
Remember to back up your system data
before changing or installing hardware.
System requirements
The ATTO ExpressPCI host adapter package
contains the host adapter, the ATTO ExpressPCI
CD and a warranty and registration card. If any
items are missing, contact your ATTO authorized
sales representative.
To install and use the ATTO ExpressPCI UL4D
and UL4S SCSI adapters you need:
• A computer with an available 64-bit PCI-X
expansion slot (preferred) or a standard 32- or
64-bit PCI expansion slot.
• The complete ATTO ExpressPCI SCSI host
adapter package.
To install and use the ATTO ExpressPCI UL5D
and ExpressPCI UL5D LP you will need
• A computer with an available x4 PCIe expansion
slot or larger, such as x8 or x16.
• The complete ATTO ExpressPCI SCSI host
adapter package.
CAUTIONCAUTION
ATTO ExpressPCI host adapters contain
components that are sensitive to
electrostatic discharge (ESD). ESD can
cause damage to the ExpressPCI host
adapter. Please follow standard methods
to avoid ESD.
Installation
Remember to back up your system data before
changing or installing hardware.
1 Plan your SCSI device connections.
If connecting both internal and external devices
to the ATTO ExpressPCI SCSI adapter, be sure
to have the appropriate cables to connect
devices.
2 Set SCSI device termination. Devices at both
ends of the SCSI bus must be terminated.
Devices in the middle of the bus, including the
ATTO ExpressPCI adapter, must have
termination removed or disabled. ATTO
ExpressPCI SCSI adapters select the proper
termination if left in auto termination mode.
3 Set SCSI IDs. Each device on the SCSI bus
requires a unique SCSI ID, one different from
the host adapter ID. The default setting for the
ATTO ExpressPCI adapter is 7.
If you need to change this setting, refer to the
ATTO Utilities Installation and Operation
manual. Also refer to your SCSI device
documentation to determine the current SCSI
ID and how to change it. Wide (16-bit) SCSI
devices can be assigned IDs 0 to 7 and 8 to 15,
while Narrow (8-bit) devices can only be
assigned IDs ranging from 0 to 7.
4 Review system documentation to select an
appropriate slot to install your adapter. The
combined power consumption of the expansion
slots must not exceed the limits for your
system. If you have more than one expansion
card installed, ensure power consumption is
within the limits outlined for your system.
5 Power down the computer and unplug the
computer from all power sources.
6 Open the case.
7Install the adapter in any open PCI expansion
slot. Consult your computer’s documentation if
you have questions about how to install an
expansion card in your system.
8 Connect SCSI devices by inserting a SCSI
cable to the connector on the ATTO
ExpressPCI host adapter until you hear a click.
Refer to Chapter 3.1 when selecting cables.
9 Close the computer case and power it up.
ATTO ExpressPCI host adapters come
preconfigured to operate properly in a variety of
common system setups. However, some systems
may benefit by tuning the adapter for optimal
performance. Refer to the
ATTO Utilities
Installation and Operation
manual for more
information on changing host adapter settings .

ATTO Technology Inc. ExpressPCI Host Adapter Installation and Operation Manual
3.1 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.
Exhibit 3.1-1 The following table lists the maximum number of devices you may connect at specific cable distances
using differential and single-ended SCSI in various SCSI environments.
Setting up cables and termination
Use high quality Ultra 320-rated, well-insulated
SCSI cables to ensure error free communications.
Exhibit 3.1-2 Several internal and external cable
connectors.
The ExpressPCI Ultra320 SCSI Host Adapter
supports two types of SCSI signaling: Low
Voltage Differential (LVD) and Single-Ended.
Devices on the same SCSI bus must use the same
signaling, either LVD or Single-Ended.
To set up cabling and termination:
1 Determine whether you are using a single
channel or dual channel host adapter model.
One external connector indicates a single
channel host adapter; two external connectors
indicate a dual channel host adapter.
2 Determine if SCSI devices are going to be
installed internally or externally.
• Total bus cable length varies by host adapter
and type of attached devices. Refer to
Exhibit 3.1-1 for details on maximum cable
length.
• If you combine Wide 16-bit and Narrow 8-
bit devices on the same connector, connect
the Wide devices first (closest to the
connector).
• Refer to the documentation for your SCSI
devices to determine if they are Wide or
Narrow, UltraWIDE SCSI, Ultra2 SCSI,
Ultra160 or Ultra 320.

Cabling and termination
• Use an LVD terminator if you are only using LVD
devices.
Although you can use a Single-Ended
terminator, all devices will be limited to Ultra
SCSI 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 may not be seen on the SCSI bus.
Some termination manufacturers provide
automatically sensing terminators.
• External terminators should be attached to the
last external device in the SCSI chain.
Don’t use any other termination on the
external SCSI chain.
The last device on an internal SCSI chain
should also be terminated in one of 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 your drive
manufacturer if you are not sure which pins
to use.
• LVD Ultra2 and Ultra160 SCSI devices cannot
supply their own termination.
Use an internal ribbon cable which has a
SCSI terminator attached to the end of it,
connect the unterminated 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.
• 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
properly 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 occur without proper termination.
• If you use both internal and external connectors
and mix Single-Ended and LVD devices on the
same bus, even if using different connectors, the
host adapter card 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 adapter automatically
detects the change, and enables 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 not
automatically.
Please refer to your ATTOI Utilities manual
for instructions on setting 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.

v ATTO Technology, Inc. ExpressPCI Host Adapter Installation and Operation Manual
Appendix C Safety, warranty, contacts
All ATTO host adapter products have been tested to meet applicable safety standards when operated in
proper electrical and thermal environments.
Safety
Please review the specifications for your specific host adapter before installing and operating it in any
computer system to ensure compatibility.
Installation
Before installing an ATTO host adapter product into your computer system, unplug the computer from
its electrical power source and allow adequate time for electrical discharge and the internal components
to cool down before removing the computer system cover. This will decrease the risk of personal injury
from electrical shock or touching the hot surface of an electrical component.
Once an ATTO host adapter is installed in a computer system, the computer cover must be reinstalled
properly before turning the computer system back on.
Operation
ATTO host adapters require adequate cooling to function properly. If you have any questions as to the
airflow provided by your computer system, please refer to your computer system manual or contact your
computer system manufacturer.
To facilitate proper air circulation, ATTO host adapters should never be operated in a computer system
without the cover installed or with an inoperable fan as this may cause safety or thermal problems which
could damage the ATTO host adapter and void the warranty.
