Introduction

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.
Glossary
Some terms used in the SCSI industry are defined below. More information is available through the
ATTO Technology website (www.attotech.com), and the SCSI Consortium
(www.iol.unh.edu/consortium).
Term Definition
ANSI American National Standards Institute
auto negotiation hardware senses and automatically responds depending on configuration
BER Bit Error Rate: a measure of transmission accuracy; the ratio of bits received in
error to bits sent
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 Check: 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.
host a processor, usually a CPU and memory, which communicates with devices over
an interface
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.
originator an initiating device; a component which originates a command
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.

3 Installing the ExpressPCI SCSI Host Adapter
You will need a basic understanding of SCSI before installing the ATTO ExpressPCI host adapter. Please
refer to Chapter 2 for a list of SCSI-related web sites. For more detailed explanations of cabling,
connectors and termination, see Chapter 3.1.
WAR N ING
before changing or installing hardware.
WAR N ING
components that are sensitive to electrostatic discharge
(ESD). ESD can cause damage to the ExpressPCI host
adapter. Please follow standard methods to avoid ESD.
Remember to back up your system data
ATTO ExpressPCI host adapters contain
System requirements
The ATTO Express PCI host adapter package
contains the host adapter, the ATTO ExpressPCI
Utilities CD and a warranty and registration card.
If any of these items are missing, contact your
ATTO authorized sales representative.
To successfully install and use your ATTO
ExpressPCI SCSI adapter you need:
❖
A computer with an available PCI slot.
❖
SCSI devices
❖
Cable(s) and terminator(s).
Installation
1 Plan your SCSI device connections (see
Chapter 3.1).
2 Shut down the system and all peripherals
before installing the adapter. After turning
off the computer, leave the power cable
plugged into a grounded outlet to discharge
static electricity.
3 Open the computer case.
Install the ATTO ExpressPCI host adapter in
4
any open PCI expansion slot. If you have
questions about how to install an expansion
card in your system, consult your
computer’s documentation.
NOTE
64/32-bit Mode: The jumpers J1 and J2, when
installed vertically, ensure ATTO ExpressPCI 64-bit cards
work correctly in 32-bit mode in all 32-bit PCI slots. These
jumpers do not force the ExpressPCI card to operate in
32-bit mode. If placed in a 64-bit mode, the ExpressPCI
card will still function in a 64-bit slot. However, removing
jumpers may cause the ExpressPCI card to function
incorrectly in some 32-bit PCI slots.
Exhibit 3-1 Consequences of enabling and disabling
jumpers J1 and J2 with an ExpressPCI 64-bit card.
ExpressPCI
64-bit card
32-bit PCI slot Correct 32-bit
64-bit PCI slot Correct 64-bit
5 Replace the computer cover.
6 Connect SCSI devices by inserting a SCSI
cable to the connector on the ATTO
ExpressPCI host adapter. Refer to
Exhibit 3.1-2 when selecting cables.
7 Power up your computer.
8 Set SCSI device termination. (see
Chapter 3.1)
9 Set SCSI IDs. Adapter default is 7.
Each device on the SCSI bus requires a unique
SCSI ID. If installing a single device, make sure you
do not assign it the same SCSI ID as your ATTO
ExpressPCI SCSI adapter. Do not change the
adapter ID if possible. For more information and
ease in changing the ID, consult the ExpressPCI
Utilities Installation and Operation Manual.
10 ATTO ExpressPCI host adapters come
preconfigured to operate properly in a
variety of common system setups. However,
some systems or setups may benefit by
tuning the adapter for optimal performance.
Use the ATTO ExpressPCI Utilities to
change host adapter settings. Refer to
Chapter 3.2 for more information.
11 If necessary, install drivers for your
operating system from the ATTO
ExpressPCI Utilities CD. Refer to
Chapter 3.2 for more information.
