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:

Preface vii
Copyright © 2004 by LSI Logic Corporation. All rights reserved.
•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 documenation 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.
When Working Inside Your Computer
Notice:Do not attempt to service the computer system yourself, except
as explained in this guide and elsewhere in LSI Logic documen-
tation. 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 any telephone or telecommunications lines from the computer.
Doing so reduces the potential for personal injury or shock.

viii Preface

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 LSI Logic MegaRAID 320-0X
controller, which is a zero-channel (ZCR) RAID PCI-X to SCSI storage adapter.
It consists of the following sections. RAID is an acronym for Redundant Array
of Independent Disks.
•Section 1.1, “Overview,” page 1-1
•Section 1.2, “Features,” page 1-3
•Section 1.3, “Hardware,” page 1-4
1.1 Overview
The LSI Logic MegaRAID 320-0X storage adapter is a low-profile, high-
performance zero-channel, intelligent PCI-X to SCSI host adapter with RAID
(Redundant Array of Independent Disks) control capabilities. The
MegaRAID 320-0X storage adapter 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
MegaRAID 320-0X storage adapter offers a cost-effective way to implement
RAID in a server.
MegaRAID SCSI 320-0X can be installed in a special PCI-X expansion slot in
a computer with a motherboard that has the LSI Logic 53C1020 or 53C1030
SCSI chip. The zero-channel adapter converts a motherboard’s own on-board
SCSI controller into a powerful PCI-X SCSI RAID solution and is targeted for
1U and 2U server environments.
The MegaRAID SCSI 320-0X is part of the LSI Logic Intel 80321-based
MegaRAID controller family and is an entry-level to mid-range RAID controller
solution.

1-2 Overview
Copyright © 2003 by LSI Logic Corporation. All rights reserved.
The MegaRAID 320-0X storage adapter 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. With this adapter in your PCI or PCI-X 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 to the SCSI bus because the chip on the storage
adapter must be reset to return to LVD or SE mode once the HVD device is
removed.
1.1.1 Operating System Support
The MegaRAID 320-0X storage adapter supports major operating systems,
including Windows (2000, Server 2003, and XP), Red Hat Linux, SuSe Linux,
Novell NetWare, SCO OpenServer, and UnixWare. Other software support
ensures data integrity by intelligently testing the network before completing
negotiation. Refer to the MegaRAID 320 Device Driver Installation User’s
Guide for more information.
The MegaRAID 320-0X storage adapter uses Fusion-MPT™ architecture for all
major operating systems for thinner drivers and better performance.

•128 MB cache memory
•PCI-X host interface
•Support for RAID levels 0, 1, 5, 10, and 50
•Advanced array configuration and management utilities
•64 Kbyte x 8 NVRAM for storing RAID system configuration information;
the MegaRAID 320 firmware is stored in flash ROM for easy upgrade.
•Battery backup for the onboard cache SDRAM using a daughter card with
battery
•Onboard tone generator to indicate events and errors
1.2.1 Drive Migration
Drive migration is the transfer of a set of hard drives in an existing configuration
from one controller to another. The drives must remain on the same channel and
be reinstalled in the same order as in the original configuration.
