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.

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
