Safety Instructions

Use the following safety guidelines to help protect your computer system from potential
damage and to ensure your own personal safety.

When Using Your Computer System

As you use your computer system, observe the following safety guidelines:

CAUTION:

Do not operate your computer system with any cover(s) (such as computer
covers, bezels, filler brackets, and front-panel inserts) removed:

• To help avoid damaging your computer, be sure the voltage selection switch on the power
supply is set to match the alternating current (AC) power available at your location:

– 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far

Eastern countries such as Japan, South Korea, and Taiwan

– 230 V/50 Hz in most of Europe, the Middle East, and the Far East. Also be sure your

monitor and attached peripherals are electrically rated to operate with the AC power
available in your location.

• To help avoid possible damage to the server board, wait five seconds after turning off the
system before removing a component from the server board or disconnecting a peripheral
device from the computer.

• To help prevent electric shock, plug the computer and peripheral power cables into
properly grounded power sources. These cables are equipped with 3-prong plugs to
ensure proper grounding. Do not use adapter plugs or remove the grounding prong from
a cable. If you must use an extension cable, use a 3-wire cable with properly grounded
plugs.

• To help protect your computer system from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply.

• Be sure nothing rests on your computer system’s cables and that the cables are not located
where they can be stepped on or tripped over.

• Do not spill food or liquids on your computer. If the computer gets wet, consult the
documentation that came with it.

• Do not push any objects into the openings of your computer. Doing so can cause fire or
electric shock by shorting out interior components.

• Keep your computer away from radiators and heat sources. Also, do not block cooling
vents. Avoid placing loose papers underneath your computer; do not place your computer
in a closed-in wall unit or on a rug.

9

When Working Inside Your Computer

Notice: Do not attempt to service the computer system yourself, except as explained in

this guide and elsewhere in Intel documentation. Always follow installation and
service instructions closely.

1. Turn off your computer and any peripherals.

2. Disconnect your computer and peripherals from their power sources. Also disconnect an y
telephone or telecommunications lines from the computer.

Doing so reduces the potential for personal injury or shock.

Also note these safety guidelines:

• When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the
cable itself. Some cables have a connector with locking tabs; if you are disconnecting this
type of cable, press in on the locking tabs before disconnect the cable. As you pull
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also,
before you connect a cable, make sure both connectors are correctly oriented and aligned.

• Handle components and cards with care. Don’t touch the components or contacts on a
card. Hold a card by its edges or by its metal mounting bracket. Hold a component such
as a microprocessor chip by its edges, not by its pins.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your computer. To prevent static
damage, discharge static electricity from your body before you touch any of your computer’s
electronic components, such as the microprocessor. You can do so by touching an unpainted
metal surface, such as the metal around the card-slot openings at the back of the computer.

As you continue to work inside the computer, periodically touch an unpainted metal surface
to remove any static charge your body may have accumulated. In addition to the preceding
precautions, you can also take the following steps to prevent damage from electrostatic
discharge (ESD):

• When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the
component in your computer. Just before unwrapping the antistatic packaging, be sure to
discharge static electricity from your body.

• When transporting a sensitive component, first place it in an antistatic container or
packaging.

• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads
and workbench pads.

Chapter 1
Overview

This section provides a general overview of the Intel® RAID Controller SRCZCRX . It
consists of the following sections.

• Section 1.1, “Overview,” page 15

• Section 1.2, “Features,” page 16

• Section 1.3, “Hardware,” page 16

1.1 Overview

The Intel RAID Controller SRCZRCX is a high-performance intelligent Peripheral
Component Interconnect to MROMB-based host adapter with Redundant Array of
Independent Disks (RAID) control capabilities. The SRCZRCX controller provides
reliability, high performance, and fault-tolerant disk subsystem management. It is an ideal
RAID solution for the internal storage of workgroup, departmental, and enterprise systems.
The SRCZRCX controller offers a cost-effective way to implement RAID in a server.

For optimum Ultra320 SCSI performance off of the server board, you must connect only LVD
devices to the bus. Do not mix SE with LVD devices, or the bus speed will be limited to the
slower SE (Ultra SCSI) SCSI data transfer rates.

The Intel RAID Controller SRCZRCX supports major operating systems, such as Microsoft*
Windows* XP, Microsoft* Windows* 2000, Microsoft* Windows Server* 2003, Novell*
NetWare*, Red Hat* Linux*, and SuSE* Linux*.

Note:

The operating systems supported by this controller may not be supported by
your server board. Please refer to the tested OS list for your server board at

http://support.intel.com/support/motherboards/server/. See also the tested

7) Set the Target IDs.
Set target identifiers (TIDs) on the SCSI devices. Each device in a channel must have a

unique TID. Provide unique TIDs for non-disk devices (CD-ROM or tapes), regardless
of the channel where they are connected. The Intel RAID Controller SRCZCRX
automatically occupies TID 7, which is the highest priority. The arbitration priority for a
SCSI device depends on its TID.

8) Power On Host System
Replace the computer cover, and reconnect the AC power cords. Turn power on to the

host computer. Ensure that the SCSI devices are powered up at the same time as, or
before, the host computer. If the computer is powered up before a SCSI device, the de vice
might not be recognized.

During boot, a BIOS message appears.
The firmware takes several seconds to initialize. During this time, the SRCZCRX

controller scans the SCSI channel(s).

The BIOS Configuration utility prompt times out after several seconds. The second portion
of the BIOS message displays the Intel RAID Controller SRCZCRX number, firmware
version, and cache SDRAM size. The numbering of the controllers follows the PCI slot
scanning order used by the host motherboard.

Chapter 3
Intel RAID Controller SRCZCRX Technical
Reference

This chapter describes the characteristics of the Intel RAID Controller SRCZCRX. This
chapter contains the following sections:

• Section 3.1, “Overview,” page 23

• Section 3.2, “Intel RAID Controller SRCZCRX Characteristics,” page 24

• Section 3.3, “Technical Specifications,” page 25

3.1 Overview

PCI-X is a high-speed standard local bus for interfacing I/O components to the processor and
memory subsystems in a server. The component height on the top and bottom of the
SRCZCRX controller follow the PCI Local Bus Specification, Revision 2.2, and PCI-X
Addendum to the PCI Local Bus Specification, Revision 1.0a. The Intel RAID Controller
SRCZCRX is used in PCI-X and PCI computer systems with PCI standard and low-profile
bracket types.

The Intel RAID Controller SRCZCRX installs into an MROMB-enabled PCI-X slot on the
server board. The server board must include an onboard SCSI controller that supports this
RAID solution.

Glossary of Terms and Abbreviations

Active
Termination

The electrical connection required at each end of the SCSI bus, composed of active voltage
regulation and a set of termination resistors. Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, and
Ultra320 SCSI require active termination.

BIOS Basic Input/Output System. Software that provides basic read/write capability. Usually kept

as firmware (ROM based). The system BIOS on the mainboard of a computer is used to boot
and control the system. The SCSI BIOS on your host adapter acts as an extension of the
system BIOS.

Configuration Refers to the way a computer is setup; the combined hardware components (computer,

monitor, keyboard, and peripheral devices) that make up a computer system; or the software
settings that allow the hardware components to communicate with each other.

Device Driver A program that allows a microprocessor (through the operating system) to direct the operation

of a peripheral device.

Differential
SCSI

A hardware configuration for connecting SCSI devices. It uses a pair of lines for each signal
transfer (as opposed to Single-Ended SCSI which references each SCSI signal to a common
ground).

Domain
Validation

EEPROM Electronically Erasable Programmable Read Only Memory.

Domain Validation is a software procedure in which a host queries a device to determine its
ability to communicate at the negotiated Ultra320 data rate.

External SCSI
Device

Fusion-MPT
Architecture

A SCSI device installed outside the computer cabinet. These devices are connected together
using specific types of shielded cables.

Fusion-MPT (Message Passing Technology) architecture consists of several main elements:
Fusion-MPT firmware, the Fibre Channel and SCSI hardware, and the operating system level
drivers that support these architectures. Fusion-MPT architecture offers a single binary,
operating system driver that supports both Fibre Channel and SCSI devices now.

Host The computer system in which a storage adapter is installed. It uses the storage adapter to

transfer information to and from devices attached to the SCSI bus.

synonymous with RAM).

NVRAM NonVolatile Random Access Memory.

28

PCI and PCI-X Peripheral Component Interconnect. A high performance local bus specification that allows

connection of devices directly to computer memory. The PCI Local Bus allows transparent
upgrades from 32-bit data path at 33 MHz to 64-bit data path at 33 MHz, and from 32-bit
data path at 66 MHz to 64-bit data path at 66 MHz.

Peripheral
Devices

A piece of hardware (such as a video monitor, disk drive, printer, or
CD-ROM) used with a computer and under the computer’s control. SCSI peripherals are
controlled through a SCSI SRCU42X controller (host adapter).

SCSI Bus A storage adapter (host adapter) and one or more SCSI peripherals connected by cables in a

linear configuration. The adapter may exist anywhere on the bus, allowing connection of both
internal and external SCSI devices. A system may have more than one SCSI bus by using a
multi-channel adapter or by using multiple adapters.

SCSI Device Any device tha t conforms to the SCSI standard and is attached to the SCSI bus by a SCSI

cable. This includes SCSI storage adapters (host adapters) and SCSI peripherals.

SCSI ID A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI bus has eight

available SCSI IDs numbered 0 through 7 (or 0 through 15 for Wide SCSI). The storage
adapter (host adapter) usually gets the highest ID (7 or 15) giving it priority to control the bus.

Single-Ended
SCSI

A hardware specification for connecting SCSI devices. It references each SCSI signal to a
common ground. This is the most common method (as opposed to differential SCSI, which
uses a separate ground for each signal).

TolerANT A technology developed and used by Intel to improve data integrity, data transfer rates, and

noise immunity through the use of active negation and input signal filtering.

Ultra SCSI A standard for SCSI data transfers. It allows a transfer rate of up to

20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit SCSI bus.

Ultra2 SCSI A standard for SCSI data transfers. It allows a transfer rate of up to

40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a
16-bit SCSI bus.

Ultra160 SCSI A standard for SCSI data transfers. It allows a transfer rate of up to 160 Mbytes/s over a 16-

bit SCSI bus.

Ultra320 SCSI A standard for SCSI data transfers. It allows a transfer rate of up to 320 Mbytes/s over a 16-

bit SCSI bus.

VHDCI Very High-Density Cable Interconnect. This cable is used to connect external connectors to

your storage adapter.
