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:

Preface vii
Copyright © 2003 by LSI Logic Corporation. All rights reserved.
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 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 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 any 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):

Preface ix

•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
series of PCI-to-SCSI storage adapters with RAID control capabilities. It
consists of the following sections.
•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 storage adapters are high-performance
intelligent Peripheral Component Interconnect to Small Computer
System Interface (PCI-to-SCSI) host adapters with Redundant Array of
Independent Disks (RAID) control capabilities. MegaRAID 320 storage
adapters provide reliability, high performance, and fault-tolerant disk
subsystem management. They are an ideal RAID solution for the internal
storage of workgroup, departmental, and enterprise systems.
MegaRAID 320 storage adapters offer a cost-effective way to implement
RAID in a server.
MegaRAID 320 storage adapters are available with one, two, or four
SCSI channels.
•The MegaRAID 320-1 storage adapter (single-channel) has one
LSI53C1020 controller chip that controls one SCSI channel. The
storage adapter has one very high-density cable interconnect
(VHDCI) 68-pin external SCSI connector and one high-density cable
interconnect (HDCI) 68-pin internal SCSI connector.
•The MegaRAID 320-2 storage adapter (dual-channel) has one
LSI53C1030 controller chip that controls two SCSI channels. The

1-2 Overview

storage adapter has two VHDCI 68-pin external SCSI connectors
and two HDCI 68-pin internal SCSI connectors.
•The MegaRAID 320-2X storage adapter (dual-channel) has one
LSI53C1030 controller chip that controls two SCSI channels. The
storage adapter has two VHDCI 68-pin external SCSI connectors
and two HDCI 68-pin internal SCSI connectors. Note that the
MegaRAID 320-2X is a PCI-X controller.
•The MegaRAID 320-4X storage adapter (quad-channel) has two
LSI53C1030 controller chips that control the four SCSI channels. The
storage adapter has four VHDCI 68-pin external SCSI connectors
and two HDCI 68-pin internal SCSI connectors. Note that the
MegaRAID 320-4X is a PCI-X controller.
The MegaRAID 320 storage adapters support 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 MegaRAID 320 storage adapters in PCI-X computer
systems with a standard bracket type. With these adapters 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.
The MegaRAID 320 storage adapters support major operating systems,
such as Windows (NT 4.0, 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.
Note: The MegaRAID 320-1 and 320-2 adapters support
Windows NT 4.0, but MegaRAID 320-2X and 320-4X do
not. Refer to the MegaRAID Device Driver Installation
User’s Guide for driver installation instructions.
The MegaRAID 320 storage adapters use Fusion-MPT™ architecture for
all major operating systems for thinner drivers and better performance.
