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 system board, wait five seconds after turning off the system before removing a component from the system 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.

Page 10

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 SRCU42E . It consists of the following sections.

• Section 1.1, “Overview,” page 15

• Section 1.2, “Features,” page 16

• Section 1.3, “Hardware,” page 17

1.1 Overview

The Intel® RAID Controller SRCU42E is a high-performance intelligent PCI Express* host adapter with Redundant Array of Independent Disks (RAID) control capabilities. The RAID Controller SRCU42E provides reliability , high performance, and fa ult-tolerant disk subsystem management. It is an ideal RAID solution for the internal storage of workgroup, departmental, and enterprise systems. The RAID controller offers a cost-effective way to implement RAID in a server.

The RAID Controller SRCU42E (dual-channel) is a PCI Express* controller that has one LSI* 53C1030 controller chip that controls two SCSI channels. The RAID controller has two VHDCI 68-pin external SCSI connectors and two HDCI 68-pin internal SCSI connectors.

The RAID Controller SRCU42E supports a low voltage differential (LVD) or a single-ended (SE) SCSI bus. With LVD, you can use cables up to 12 meters long. Throughput on each SCSI channel can be as high as 320 Mbytes/s.

You can install the Intel a standard bracket type. With this RAID controller in your PCI-Express system, you can connect SCSI devices over a SCSI bus.

For Ultra320 SCSI performance, 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. Do not connect a high voltage differential (HVD) device.

The Intel Windows* XP, Microsoft* Windows* 2000, Microsoft* Windows Server* 2003, Novell* NetWare*, Red Hat* Linux*, and SuSE* Linux*.

RAID Controller SRCU42E supports major operating systems, such as Microsoft*

1.3.2 Configuration on Disk

Configuration on Disk saves configuration information both in NVRAM on the Intel® RAID Controller SRCU42E and on the disk drives attached to the RAID Controller SRCU42 E. If the RAID Controller SRCU42E is replaced, the new RAID Controller SRCU42E detects the actual RAID configuration from the configuration information on the drives. This maintains the integrity of the data on each drive, even if the drives have changed their target ID.

Note:

1.3.3 Drive Roaming

The RAID Controller SRCU42E supports drive roaming across channels on the same RAID Controller SRCU42E. Drive roaming lets an Intel Raid RAID Controller SRCU42E detect the actual RAID configuration, maintaining the integrity of the data on each disk drive, even if the disk drives have changed channels and/or target ID.

Note:

Configuration on Disk does not work if you change both the RAID Controller

SRCU42E and the SCSI connectors to different connectors on the new RAID

controller. It works only if you make one change at a time.

The RAID Controller SRCU42E does not support drive roaming across

channels when cluster mode is enabled.

6) 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 SRCU42E automatically occupies TID 7, which is the highest priority. The arbitration priority for a SCSI device depends on its TID.

7) Connect SCSI devices to the Intel® RAID Controller SRCU42E. Use SCSI cables to connect SCSI devices to the RAID Controller SRCU42E. To connec t the SCSI devices:

a. Disable termination on any SCSI device that does not sit at the end of the SCSI bus. b. Configure all SCSI devices to supply TERMPWR. c. Connect cables to the SCSI devices. The maximum cable length for Fast SCSI (10

Mbytes/s) devices or SE is 3 meters; it is 1.5 meters for Ultra SCSI devices; it is 12 meters for LVD devices. You can connect up to 15 Ultra SCSI devices to each SCSI channel.

System throughput problems can occur if SCSI cables are not the correct type. To minimize the potential for problems:

– Use cables no longer than 12 meters for Ultra160 and Ultra320 devices. – For SE SCSI devices, use the shortest SCSI cables (no longer than 3 meters

for Fast SCSI, no longer than 1.5 meters for an 8-drive Ultra SCSI system,

and no longer than 3 meters for a 6-drive Ultra SCSI system). – Use active termination. – Avoid clustering the cable nodes. – The cable stub length must be no greater than 0.1 meter (4 inch es.) – Use high impedance cables. – Route SCSI cables carefully.

8) Set SCSI Termination The SCSI bus is an electrical transmission line and must be terminated properly to

minimize reflections and losses. Set termination at each end of the SCSI cable(s). For a disk array, set SCSI bus termination so that removing or adding a SCSI device does

not disturb termination. An easy way to do this is to connect the RAID Controller SRCU42E to one end of the SCSI cable and to connect an external terminator module at the other end of the cable. You can then connect SCSI disk drives to the connectors between the two ends of the cable. If necessary, disable termination on the SCSI devices. (This is not necessary for Ultra320 and Ultra160 SCSI drives.)

Set the termination so that SCSI termination and TermPWR are intact when any disk drive is removed from a SCSI channel, as shown in Figure 2.3.

9) 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 RAID Controller

SRCU42E 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 SRCU42E number, firmware version, and cache SDRAM size. The numbering of the controllers follows the PCI slot scanning order used by the host system board.

Chapter A 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 controller 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 the RAID controller is installed. It uses the RAID controller

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

Host Adapter Board (HAB)

Internal SCSI Device

Main Memory The part of a computer’s memory which is directly accessible by the CPU (usually

A circuit board or integrated circuit that provides a device connection to the computer system.

A SCSI device installed inside the computer cabinet. These devices are connected together using an unshielded ribbon cable.

synonymous with RAM).

NVRAM NonVolatile Random Access Memory.

Page 33

PCI Express* 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 RAID controller (host controller).

SCSI Bus A RAID controller (host controller) and one or more SCSI peripherals connected by cables

in a linear configuration. The controller 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 controller or by using multiple controllers.

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

cable. This includes SCSI RAID controllers (host controllers) 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 RAID controller (host controller) 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 RAID controller.
