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 5 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.

vi Preface

•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.

Preface vii
Copyright © 2003-2008 by LSI Corporation. All rights reserved.
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 MegaRAID 320 series of
PCI-to-SCSI Storage Adapters with RAID control capabilities. It consists
of the following sections.
•Section 1.1, “Overview”
•Section 1.2, “Features”
•Section 1.3, “Hardware”
1.1 Overview
The MegaRAID 320 Storage Adapters are high-performance intelligent
PCI-to-SCSI host adapters with 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. There are two versions of the MegaRAID 320-1 Storage
Adapter. The following are descriptions of the adapters:
•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.

1-2 Overview
Copyright © 2003-2008 by LSI Corporation. All rights reserved.
•The MegaRAID 320-2 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.
•The MegaRAID 320-2E (Express) Storage Adapter has one 80332
processor that controls two SCSI channels. The Storage Adapter has
two UHDCI 68-pin external SCSI connectors and two HDCI 68-pin
internal SCSI connectors. Note that the MegaRAID 320-2E is a
PCI-Express controller.
•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.
PCI, PCI-X, and PCI-Express are I/O architectures designed to increase
data transfers without slowing down the central processing unit (CPU).
You can install the MegaRAID 320 PCI and PCI-X Storage Adapters in
PCI-X computer systems with a standard bracket type. With these
adapters in your system, you can connect SCSI devices over a SCSI bus.
PCI-Express goes beyond the PCI specification in that it is intended as
a unifying I/O architecture for various systems: desktops, workstations,
mobile, server, communications, and embedded devices.
Note: For Ultra320 SCSI performance, you must connect only
LVD devices to the bus. Do not connect a high voltage
differential (HVD) device to the controller. Do not mix SE
with LVD devices, or the bus speed will be limited to the
slower SE (Ultra SCSI) SCSI data transfer rates.

1.1.1 Operating System Support
The MegaRAID 320 Storage Adapters support major operating systems,
such as 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.
Note: The MegaRAID 320 Storage Adapters do not support the
Windows NT®operating system.
The MegaRAID 320 Storage Adapters use Fusion-MPT™ architecture for
all major operating systems for thinner drivers and better performance.
Refer to the MegaRAID Device Driver Installation User’s Guide for driver
installation instructions.
1.1.2 Technical Support

controller or obtaining a driver for an operating system other than the
ones already listed in Section 1.1.1, “Operating System Support,” contact
