Chapter 1: Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the E7520 Lindenhurst chipset,

The X6DH8-G2+/X6DHE-G2+ motherboard provides the performance and feature

set required for dual processor-based servers, with confi guration options optimized

for communications, presentation, storage, computation or database applications.

The Intel E7520 Lindenhurst chipset consists of the following components: the

Lindenhurst Memory Controller Hub (MCH), the 82801ER I/O Controller Hub 5-R

(ICH5-R), and the Intel PCI-X Hub.

The E7520 Lindenhurst MCH supports single or dual Xeon processors with Front

Side Bus speeds of up to 800 MHz. Its memory controller provides direct connec-

tion to two channels of registered DDRII- 400 with a marched system bus address

and data bandwidths of up to 6.4GB/s. The Lindenhurst also supports the new

PCI Express high speed serial I/O interface for superior I/O bandwidth. The MCH

provides three confi gurable x8 PCI Express interfaces which may alternatively be

confi gured as two independent x4 PCI Express interfaces. These interfaces support

connection of the MCH to a variety of other bridges that are compliant with the PCI

Express Interface Specifi cation, Rev. 1.0a. The MCH interfaces with the 82801ER

I/O Controller Hub 5-R (ICH5R) via a dedicated Hub Interface supporting a peak

bandwidth of 266 MB/s using a x4 base clock of 66 MHz. The PXH provide con-

nection between a PCI Express interface and two independent PCI bus interfaces

that can be confi gured for standard PCI 2.2 protocol, as well as the enhanced high-

frequency PCI-X protocol. The PXH can be confi gured to support for 32- or 64-bit

PCI devices running at 33 MHz, 66 MHz, 100 MHz, and 133 MHz.

The ICH5R I/O Controller Hub provides legacy support similar to that of previous

ICH-family devices, but with extensions in RAID 0,1 support, Serial ATA Technology,

and an integrated ASF Controller. In addition, the ICH5R also provides various inte-

grated functions, including a two-channel Ultra ATA/100 bus master IDE controller,

USB 2.0 host controllers, an integrated 10/100 LAN controller, an LPC fi rmware hub

(FWH) and Super IO interface, a System Management Interface, a power manage-

ment interface, integrated IOxAPIC and 8259 interrupt controllers.

X6DH8-G2+/X6DHE-G2+ User's Manual

1-3 Special Features

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when AC

power is lost and then restored to the system. You can choose for the system to

remain powered off (in which case you must hit the power switch to turn it back on)

or for it to automatically return to a power- on state. See the Power Lost Control

setting in the Advanced BIOS Setup section (Peripheral Device Confi guration) to

change this setting. The default setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X6DH8-G2+/

X6DHE-G2+. All have an onboard System Hardware Monitor chip that supports

PC health monitoring.

Onboard Voltage Monitors for the CPU Cores, +3.3V, +5V, +12V,

-12V and +3.3V Standby

An onboard voltage monitor will scan these voltages continuously. Once a voltage

becomes unstable, a warning is given or an error message is sent to the screen.

Users can adjust the voltage thresholds to defi ne the sensitivity of the voltage

monitor.

Fan Status Monitor via BIOS and SDIII

The PC health monitor can check the RPM status of the cooling fans. The onboard

CPU and chassis fans are controlled by Thermal Management via BIOS and Supero

Doctor III.

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will turn

on the thermal control fan whenever the CPU temperature exceeds a user-defi ned

threshold. The overheat circuitry runs independently from the CPU. It can continue

to monitor for overheat conditions even when the CPU is in sleep mode. Once it

detects that the CPU temperature is too high, it will automatically turn on the ther-

mal control fan to prevent any overheat damage to the CPU. The onboard chassis

thermal circuitry can monitor the overall system temperature and alert users when

the chassis temperature is too high.

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It continues to operate when

the system enters Standby mode. When in sleep mode, the CPU will not run at

full power, thereby generating less heat.

Chapter 1: Introduction

CPU Overheat LED and Fan Fail Control

This feature is available when the user enables the CPU overheat/Fan Fail warn-

ing function in the BIOS. This allows the user to defi ne an overheat temperature.

When this temperature is exceeded, both the overheat fan and the warning LED

are triggered.

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS

environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notify the user of certain system events. For example, if the system is running

low on virtual memory and there is insuffi cient hard drive space for saving the

data, you can be alerted of the potential problem. You can also confi gure Supero

Doctor to provide you with warnings when the system temperature goes beyond

a pre-defi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -

cation defi nes a fl exible and abstract hardware interface that provides a standard

way to integrate power management features throughout a PC system, including its

hardware, operating system and application software. This enables the system to

automatically turn on and off peripherals such as CD-ROMs, network cards, hard

disk drives and printers. This also includes consumer devices connected to the PC

such as VCRs, TVs, telephones and stereos.

In addition to enabling operating system-directed power management, ACPI

provides a generic system event mechanism for Plug and Play and an operating

system-independent interface for confi guration control. ACPI leverages the Plug

and Play BIOS data structures while providing a processor architecture-independent

implementation that is compatible with Windows 2000, Windows XP and Windows

Server 2003.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will wake-up and the LED will automatically stop blinking and remain on.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button to make the system enter a SoftOff state. The monitor will be

suspended and the hard drive will spin down. Pressing the power button again

will cause the whole system to wake-up. During the SoftOff state, the ATX power

supply provides power to keep the required circuitry in the system alive. In case

the system malfunctions and you want to turn off the power, just press and hold

1-11

X6DH8-G2+/X6DHE-G2+ User's Manual

the power button for 4 seconds. This option can be set in the Power section of

the BIOS Setup routine.

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem ringing

when the system is in the SoftOff state. Note that external modem ring-on can only

be used with an ATX 2.01 (or above) compliant power supply.

Wake-On-LAN (WOL)

Wake-On-LAN is defi ned as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and asset

tracking can occur after hours and on weekends so that daily LAN traffi c is kept to

a minimum and users are not interrupted. The motherboard has a 3-pin header

(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. In addition, an onboard LAN controller can also support WOL

without any connection to the WOL header. The 3-pin WOL header is to be used

with a LAN add-on card only.

Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.

1-6 Power Supply

As with all computer products, a stable power source is necessary for proper and

reliable operation. It is even more important for processors that have high CPU

clock rates.

The SUPER X6DH8-G2+/X6DHE-G2+ accommodates ATX 24-pin power supplies.

Although most power supplies generally meet the specifi cations required by the

CPU, some are inadequate. You should use one that will supply at least 400W of

power. Your power supply must supply 1.5A for the Ethernet ports. The +12V, 4-pin

power connector (J32) is required to provide adequate power supply to the system.

Additionally, you should also use the onboard 12V 8-pin power connector (J1D1)

to support Intel Xeon CPUs. Failure to provide this extra power will result in CPU

instability. See Section 2-5 for details on connecting the power supply.

It is strongly recommended that you use a high quality power supply that meets ATX

power supply Specifi cation 2.02 or above. It must also be SSI compliant (info at

http://www.ssiforum.org/). Additionally, in areas where noisy power transmission is

present, you may choose to install a line fi lter to shield the computer from noise. It

is recommended that you also install a power surge protector to help avoid problems

caused by power surges.

Chapter 1: Introduction

1-7 Super I/O

The disk drive adapter functions of the Super I/O chip include a fl oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock genera-

tor, drive interface control logic and interrupt and DMA logic. The wide range of

functions integrated onto the Super I/O greatly reduces the number of components

required for interfacing with fl oppy disk drives. The Super I/O supports 360 K, 720

K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s

or 1 Mb/s.It also provides two high-speed, 16550 compatible serial communication

ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable

baud rate generator, complete modem control capability and a processor interrupt

system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps

as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which

support higher speed modems.

The Super I/O supports one PC-compatible printer port (SPP), Bi-directional Printer

Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).

The Super I/O provides functions that comply with ACPI (Advanced Confi guration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through an SMI or SCI function pin. It also features auto power management

to reduce power consumption.

2-1 Static-Sensitive Devices

Electrostatic-Discharge (ESD) can damage electronic com ponents. To prevent dam-

age to your system board, it is important to handle it very carefully. The following

measures are generally suffi cient to protect your equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the board from the antistatic

bag.

• Handle the board by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the motherboard and peripherals back into their antistatic bags when not in

use.

• For grounding purposes, make sure your computer chassis provides excellent

conductivity between the power supply, the case, the mounting fasteners and

the motherboard.

• Use only the correct type of onboard CMOS battery. Do not install the onboard

upside down battery to avoid possible explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When

unpacking the board, make sure the person handling it is static protected.

Power Fault

Connect a cable from your power sup-

ply to the Power Fault header (JP12)

to provide warning of power supply

failure. This warning signal is passed

through the PWR_LED pin to indicate

an occurrence of power failure on the

chassis. You need to use this header

(JP12) with the Alarm Reset header

(JP14) together for it to work prop-

erly. See the table on the right for pin

defi nitions.

Alarm Reset (JP14)

The system will notify you in the

event of a power supply failure. Use

this feature to clear alarm when

Supermicro's redundant power supply

units are installed in the chassis. If

you only have a single power supply

installed, you should leave the pins

open (the default setting) to prevent

false alarms. See the table on the right

Explanation of
Jumpers

To modify the operation of the

motherboard, jumpers can be used

to choose between optional settings.

Jumpers create shorts between two

pins to change the function of the

connector. Pin 1 is identifi ed with

a square solder pad on the printed

circuit board. See the motherboard

layout pages for jumper locations.

Note: On two pin jumpers, "Closed"

means the jumper is on and "Open"

means the jumper is off the pins.

Chapter 2: Installation

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact

pads to prevent the accidental clearing of CMOS. To clear CMOS, use a metal

object such as a small screwdriver to touch both pads at the same time to short

the connection. Always remove the AC power cord from the system before clear-

ing CMOS. Note: For an ATX power supply, you must completely shut down the

system, remove the AC power cord and then short JBT1 to clear CMOS. Do not

use the PW_ON connector to clear CMOS.

Watch Dog

JWD controls Watch Dog, a system

monitor that takes action when a soft-

ware application hangs. Close pins

1-2 to reset the system if a program

freezes. Close pins 2-3 to generate a

non-maskable interrupt for the program

that hangs. (This requires software

implementation). Watch Dog must also

be enabled in the BIOS.

GLAN LEDs

There are two GLAN ports on the moth-

erboard. Each Gigabit Ethernet LAN port

has two LEDs. The yellow LED indicates

activity, while the power LED may be green,

amber or off to indicate the speed of the

connection. See the table at right for the

status associated with the second LED.

SCSI Channel Activity LED
Indicators (X6DH8-G2+ only)

Two LEDs (DA1, DA2) to indicate SCSI

activity are located near the SCSI controller

(AIC-7902) chip. DA1 indicates the activity

status of SCSI Channel A, and DA2 DA1

indicates the activity status of SCSI Channel

B. See the table at right for the functions

associated with each LED.

Note the following when connecting the fl oppy and hard disk drive cables:

• The fl oppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single fl oppy disk drive ribbon cable has 34 wires and two connectors to provide

for two fl oppy disk drives. The connector with twisted wires always connects to

drive A, and the connector that does not have twisted wires always connects to

drive B.

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all

of the procedures below and still need assistance, refer to the ‘Technical Support

Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.

Note: Always disconnect the power cord before adding, changing or installing

any hardware components.

Before Power On

1. Make sure no short circuits exist between the motherboard and chassis.

2. Disconnect all ribbon/wire cables from the motherboard, including those for the

keyboard and mouse.

3. Remove all add-on cards.

4. Install one CPU (making sure it is fully seated) and connect the chassis speaker

and the power LED to the motherboard. (Check all jumper settings as well.)

5. Use only the correct type of CMOS onboard battery as recommended by the

Manufacturer. Do not install the onboard battery upside down to avoid pos-

sible explosion.

No Power

1. Make sure no short circuits exist between the motherboard and the chassis.

2. Verify that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

4. Turn the power switch on and off to test the system.

5. The battery on your motherboard may be old. Check to verify that it still supplies

~3VDC. If it does not, replace it with a new one.

No Video

1. If the power is on but you have no video, remove all the add-on cards and cables.

(Note: By default, the onboard speaker is enabled.)

2. Remove the memory and turn on the system.

3. Use the speaker to determine if any beep codes exist. (Refer to the Appendix for

details on beep codes.) If you've got a no-memory beep code, you will need

to replace the memory modules with new and correct ones, for your system

memory is either bad or incompatible. If you do not have a no-memory beep

code, please call the technical support.

3-1

X6DH8-G2+/X6DHE-G2+ User's Manual

NOTE

If you are a system integrator, VAR or OEM, a POST diagnostics

card is recommended. For I/O port 80h codes, refer to App. B.

Memory Errors

1. Make sure the DIMM modules are properly and fully installed.

2. Determine if different speeds of DIMMs have been installed and verify that the

BIOS setup is confi gured for the fastest speed of RAM used. It is recom-

mended to use the same RAM speed for all DIMMs in the system.

3. Make sure you are using the correct type of Registered ECC DDR2-400 (PC3200)

SDRAM (recommended by the manufacturer.)

4. Check for bad DIMM modules or slots by swapping a single module between

two slots and noting the results.

5. Make sure all memory modules are fully seated in their slots. As an interleaved

memory scheme is used, you must install two modules at a time, beginning

with Bank 1, then Bank 2, and so on (see Section 2-3).

6. Check the position of the 115V/230V switch on the power supply.

Losing the System’s Setup Confi guration

1. Ensure that you are using a high quality power supply. A poor quality power

supply may cause the system to lose the CMOS setup information. Refer to

Section 1-6 for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still supplies

~3VDC. If it does not, replace it with a new one.

3. If the above steps do not fi x the Setup Confi guration problem, contact your

vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note

that as a motherboard manufacturer, Super Micro does not sell directly to end-us-

ers, so it is best to fi rst check with your distributor or reseller for troubleshooting

services. They should know of any possible problem(s) with the specifi c system

confi guration that was sold to you.

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X6DH8-G2+/

X6DHE-G2+. The Phoenix ROM BIOS is stored in a fl ash chip and can be easily

upgraded using a fl oppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been added or

deleted and might not yet be recorded in this manual. Please refer to the Manual

Download area of the Supermicro web site <http://www.supermicro.com> for any

changes to the BIOS that may not be refl ected in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and

PS/2® compatible computers. The Phoenix BIOS stores the system parameters,

type of disk drives, video displays, etc. in the CMOS. The CMOS memory requires

very little electrical power. When the computer is turned off, a backup battery pro-

vides power to the CMOS Logic, enabling it to retain system parameters. Each time

the computer is powered on, the computer is confi gured with the values stored in

the CMOS Logic by the system BIOS, which gains control at boot-up.

How To Change the Confi guration Data

The CMOS information that determines the system parameters may be changed by

entering the BIOS Setup utility. This Setup utility can be accessed by pressing the

<Delete> key at the appropriate time during system boot. (See below.)

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory test. As

the memory is being tested, press the <Delete> key to enter the main menu of the

BIOS Setup utility. From the main menu, you can access the other setup screens,

such as the Security and Power menus. Beginning with Section 4-3, detailed de-

scriptions are given for each parameter setting in the Setup utility.

Warning: Do not shut down or reset the system while updating BIOS

to prevent possible boot failure.

CPU Temperature Threshold

Fan Speed Control Modes

This feature allows the user to decide how the system controls the speeds of the

onboard fans. The CPU temperature and the fan speed are correlative. When the

CPU on-die temperature increases, the fan speed will also increase, and vice versa.

If the option is set to “3-pin fan”, the fan speed is controlled by voltage. If the option

is set to “4-pin”, the fan speed will be controlled by Pulse Width Modulation (PWM).

Select “3-pin” if your chassis came with 3-pin fan headers. Select “4-pin” if your

chassis came with 4-pin fan headers. Select “Workstation” if your system is used as

a Workstation. Select “Server” if your system is used as a Server. Select “Disable”

to disable the fan speed control function to allow the onboard fans to run at the

full speed (12V) at all the time. The Options are: 1. Disable, 2. 3-pin (Server), 3.

3-pin (Workstation), 4. 4-pin (Server), and 5. 4-pin (Workstation).

Fan 1-FAN6/Fan 7 (CPU Fan1)/Fan 8 (CPU Fan2): If the feature of Auto Fan

Control is enabled, the BIOS will automatically display the status of the fans

indicated in this item.

Voltage Monitoring

This feature displays the voltage status of the following items:

Note: In the Windows OS environment, the Supero Doctor III settings take pre-

cedence over the BIOS settings. When fi rst installed, Supero Doctor III adopts

the temperature threshold settings previously set in the BIOS. Any subsequent

changes to these thresholds must be made within Supero Doctor, since the SD

III settings override the BIOS settings. For the Windows OS to adopt the BIOS

temperature threshold settings, please change the SDIII settings to be the same

as those set in the BIOS.

additional word-bitmap (xxxx) indicating the address line or bits that have failed. For

example, “2C 0002” means address line 1 (bit one set) has failed. “2E 1020" means

data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also

sends the bitmap to the port-80 LED display. It fi rst displays the checkpoint code,

followed by a delay, the high-order byte, another delay, and then the loworder byte of

the error. It repeats this sequence continuously.

Installing Software Drivers and the Windows

Operating System

After all the hardware has been installed, you must fi rst confi gure the Adaptec

Embedded Serial ATA RAID Driver before you install the Windows operating system.

The necessary drivers are all included on the Supermicro bootable CDs that came

packaged with your motherboard. (The following section provides information on

Adaptec's SATA RAID Driver based on the Intel ICH5R Controller. For detailed
information on Adaptec's SCSI SATA HostRAID Utility, please refer to the CDs
included in the shipping package)

C-1 Introduction to the Adaptec Embedded Serial ATA RAID
Controller Driver

Serial ATA (SATA)

Serial ATA(SATA) is a physical storage interface. It uses a single cable with a

minimum of four wires to create a point-to-point connection between devices. It

is a serial link which supports SATA Transfer rates from 150MBps. Because the

serial cables used in SATA are thinner than the traditional cables used in Paral-

lel ATA(PATA), SATA systems have better airfl ow and can be installed in smaller

chassis than Parallel ATA. In addition, the cables used in PATA can only extend

to 40cm long, while Serial ATA cables can extend up to one meter. Overall, Serial

ATA provides better functionality than Parallel ATA.

Introduction to the Intel ICH5R I/O Controller Hub

Located in the South Bridge of the Intel E7520 (Lindenhurst) Chipset, the ICH5R

I/O Controller Hub provides the I/O subsystem with access to the rest of the sys-

tem. It supports 2-channel Ultra ATA/100 Bus Master IDE controller (PATA) and

two Serial ATA (SATA) Host Controllers, which support up to two Serial ATA ports

and up to two RAID drives. The ICH5R I/O Controller Hub supports the following

Parallel ATA (PATA) and Serial (SATA) device confi gurations:

ATA Operate Mode

You can select from the following two modes: Combined Mode and Enhanced

Mode.

Combined Mode:

In this mode, system BIOS assigns the traditional IRQ 14 and IRQ 15 for the use

of HDD. Up to 4 ATA devices are supported by this mode.

C-1

X6DH8-G2+/X6DHE-G2+ User's Manual

Within the Combined Mode, the following three modes are supported:

Non-Combined Mode: Parallel ATA only:with the maximum of 4 devices sup-

ported;

Non-Combined Mode: Serial ATA only:with the maximum of 2 devices supported;

Combined Mode: SATA devices and PATA: with the support of 2 devices each

(total: 4 devices maximum). (For IDE/SATA confi gurations, please refer to the table

below.)

Primary Master(=PM) Yes Yes No No No No
Primary Slave(=PS) Yes No Yes No No No
Secondary Master(=SM)

Yes No No Yes No No
Secondary Slave(=SS) Yes No No No Yes No
SATA Port0 No SM SM PM PM PM
SATA Port1 No SS SS PS PS PS
*Note: (No=Not Present, Yes=Present) Also, if Logical Primary is
selected, the IDE channels are no longer available.

Enhanced Mode:

In this mode, system BIOS will automatically search for all available IRQs for the

use of HDD. For newer Operating Systems that support the Enhanced Mode, such

as Windows XP, Windows 2000, and Windows 2003, you can set SATA and PATA

to the Enhanced Mode. (The newer Operating Systems can accommodate both

Enhanced Mode and Combined Mode and support up to 6 ATA devices.)

(Please refer to the "Advanced Chipset Control" under the "Advanced" Setup in the

BIOS for the selection of Combined Mode or Enhanced Mode.)

The Adaptec Embedded Serial ATA with HostRAID Controller
Driver

Adaptec's Embedded Serial ATA RAID with HostRAID controller adds RAID func-

tionality to the Serial ATA I/O controller by supporting RAID 0 (Striping) or RAID

1 (Mirroring) to enhance the industry's pioneer PCI-to-e host controller products.

RAID striping (RAID 0) can greatly improve hard disk I/O performance because

of its capability in striping data across multiple drives. RAID mirroring (RAID 1)

allows the data to be simultaneously written to two drives, so critical data is al-

ways available even if a single hard disk fails. Due to the built-in functionality, the

X6DH8-G2+/X6DHE-G2+ is specially designed to keep pace with the increasing

performance demands of computer systems by improving disk I/O throughput and

providing data accessibility regardless of a single disk failure. By incorporating the

Adaptec Embedded Serial ATA into the motherboard design, Supermicro's X6DH8-

G2+/X6DHE-G2+ offers the user with the benefi ts of SATARAID without the high

costs associated with hardware RAID applications.

(Note: For Adaptec's RAID Driver Installation Instructions, please refer to the

Adaptec RAID Controller User's Guide: "Emb_SA_RAID_UG.pdf" in the CD that

came with this motherboard. You can also download a copy of Adaptec's User's

Guide from our web site at www.supermicro.com.)

Using the Adaptec RAID Confi guration Utility (ARC)

The Adaptec RAID Confi guration Utility is an embedded BIOS Utility, including:

Array Confi guration Utility: Use this utility when you want to create, confi gure and

manage arrays.

Disk Utilities: Use this option to format or verify disks.

To run the Adaptec RAID Confi guration Utility, you will need to enable the RAID

function in the system BIOS (refer to Chapter 4 for System BIOS Confi gurations),

Assigning Array Properties

Once you've create a new array, you are ready to assign the properties to the

array.

Caution: Once the array is created and its properties are assigned,

you cannot change the array properties using the ACU. You will need to use the

Adaptec Storage Manager - Browser Edition. (Refer to Adaptec's User's Guide in

the enclosed CD.)

To assign properties to the new array:

1. In the Array Properties menu (as shown in the following screen), select an array

type and press Enter.

Note: only the available array types: RAID 0, and RAID1, are displayed on the

screen. (RAID 0 or RAID 1 requires two drives.)

C-8

Appendix C: Software Installation Instructions

2. Under the item "Arrays Label", type in an label and press Enter. (Note: The label

shall not be more than 15 characters.)

3. For RAID 0, select the desired stripe size. (Note: Available stripe sizes are 16,

32, and 64 KC-default. It is recommended that you do not change the default set-

ting.)

4. The item: "Create RAID via" allows you to select between the different creating

methods for RAID 0 and RAID 1.

The following table gives examples of when each is appropriate.

Raid Level Create Via When Appropriate

RAID 0 No Init Creating a RAID 0 on new drives
RAID 0 Migrate

(*Note)

RAID 1 Build1 Any time you wish to create a RAID 1, but especially if

RAID 1 Clear Creating a RAID 1 on new drives, or when you want to

RAID 1 Quick

RAID 1 Init

Creating a RAID 0 from one new drive and
one drive with data you wish to preserve

you have data on one drive that you wish to preserve

ensure that the array contains no data after creation.
Fastest way to create a RAID 1.
Appropriate when using new drives

Note: If you select Migrate for RAID 0, or Build for RAID 1, you will be asked to
select the source drive. The contents of the source drive will be preserved. However,
the data on the new drive will be lost.

C-9

X6DH8-G2+/X6DHE-G2+ User's Manual

5. When you are fi nished, press Done (as the screen shown below).

Notes:

1. Before adding a new drive to an array, back up any data contained on the new

drive. Otherwise, all data will be lost.

2. If you stop the Build or Clear process on a RAID 1 from ACU, you can restart

it by pressing Ctrl+R.

3. A RAID 1 created using the Quick Init option may return some data mis-com-

pares if you later run a consistency check. This is normal and is not a cause for

concern.

4. The ACU allows you to use drives of different sizes in a

RAID . However, during a build operation, only the smaller drive can be selected

as the source or fi rst drive.

5. When migrating from single volume to RAID 0, migrating from a larger drive to

a smaller drive is allowed. However, the destination drive must be at least half the

capacity of the source drive.

6. Adaptec does not recommend that you migrate or build an array on Windows

dynamic disks (volumes), as it will result in data loss.

Warning: Do not interrupt the creation of a RAID 0 using the Migrate option. If you

do, you will not be able to restart, or to recover the data that was on the source

drive.
