SCSI 320-0X ZCR Controller

Quick Installation Guide

This document describes how to install the MegaRAID SCSI
320-0X ZCR (zero-channel RAID) controller. The MegaRAID
SCSI 320-0X ZCR Controller can be installed in a special
PCI-X expansion slot in a computer with a mainboard that
has the LSI Logic 53C1020 or 53C1030 SCSI chip.

The zero-channel adapter converts a mainboard’s onboard
SCSI controller into a powerful PCI-X SCSI RAID solution
and is targeted for one-unit and two-unit server
environments.

Step 2 Prepare the Computer

Perform the following steps to install the MegaRAID SCSI
320-0X ZCR Controller:

Step 1 Unpack the MegaRAID SCSI 320-0X ZCR

your system configuration to ensure no loss of
data.

Controller

Unpack the MegaRAID SCSI 320-0X ZCR
Controller in a static-free environment. Remove
the MegaRAID SCSI320-0X ZCR Controller from
the antistatic bag and inspect it for damage.

If the MegaRAID SCSI 320-0X ZCR Controller
appears to be damaged, or if the MegaRAID

Step 3 Review the MegaRAID Controller Jumpers and

Connectors

Figure 1 shows the location of the jumpers and

connectors on the MegaRAID SCSI 320-0X ZCR
Controller. The jumpers are set at the factory and
you usually do not need to change them.

Step 4 Install the MegaRAID SCSI 320-0X ZCR

Controller on the Mainboard

Insert the MegaRAID SCSI 320-0X ZCR
Controller in a PCI-X ZCR slot on the mainboard,
as shown in Figure 2. Press down gently but
firmly to ensure the card is properly seated in the
slot. Secure the MegaRAID SCSI 320-0X ZCR
Controller to the computer chassis with the
bracket screw.

Step 7 Power-Up the Computer

Replace the computer cover and reconnect the
power cord(s). Turn on power to the computer.
During boot, a MegaRAID BIOS message similar
to the following displays:

LSI MEGARAID BIOS VERSION xxxx [date]
Copyright(c) 2005, LSI Logic Corp.
HA-1 (Bus x Dev y) LSI MegaRAID SCSI 320­0x PCI-X
Standard FW xxxx DRAM=xxx MB(SDRAM)

The firmware takes several seconds to initialize.
During this time the adapter scans the SCSI
bus(es).

Step 8 Run the MegaRAID BIOS Configuration Utility

When the message “Press <Ctrl><M>” appears
on the screen, press <Ctrl> <M> immediately to
run the MegaRAID BIOS Configuration Utility.

Note: Refer to the MegaRAID Configuration Software

User’s Guide on the MegaRAID Universal

Software Suite CD for detailed steps on
configuring physical arrays and logical drives.

Step 9 Install the Operating System Driver

The MegaRAID SCSI 320-0X ZCR Controller can
operate under MS-DOS or any DOS-compatible
operating system using the standard AT BIOS
INT 13h Hard Disk Drive interface. To operate
with other operating systems, you must install
software drivers.

The MegaRAID Universal Software Suite CD
includes drivers for the supported operating
systems. You can view the supported operating
systems and download the latest drivers for RAID
adapters on the LSI Logic web site at http://www
.lsilogic.com/downloads/selectDownload.do.

Access the download center and follow the steps
to download the driver.

Refer to the MegaRAID Device Driver Installation
User’s Guide on the MegaRAID Universal
Software Suite CD for details on installing the
driver. Be sure to use the latest Service Packs
provided by the operating system manufacturer
and review the readme file that accompanies the
driver.

SUPPORTED RAID LEVELS

The MegaRAID SCSI 320-0X ZCR Controller supports disk
arrays using the following RAID levels:

• RAID 0 (Data Striping): Data is striped across all disks
in the array, enabling fast data throughput. There is no
data redundancy. All data is lost if any disk fails. (1–30
disk drives)

• RAID 1 (Disk Mirroring): Data is written simultaneously
to two disks, providing complete data redundancy if one
disk fails. The array capacity is equal to the size of the
smaller of the two hard drives. (2 disk drives)

• RAID 5 (Disk Striping with Distributed Parity): Data is
striped across all disks in the array. Part of the capacity
of each disk stores parity information that reconstructs
data if a disk fails. Provides good data throughput for
applications with high read request rates. (3–30 disk
drives)

• RAID 10 (RAID 1 and RAID 0 in Spanned Arrays): Uses
mirrored pairs of disks to provide complete data
redundancy. Provides high data throughput rates. (4–16
disk drives; eight spans times two hard drives in each
array)

• RAID 50 (RAID 5 and RAID 0 in Spanned Arrays): Uses
both parity and disk striping across multiple disks to
provide complete data redundancy. Provides high data
throughput rates. (6–30 disk drives)
