EFORE YOU START
Thank you for choosing our product. Before you start installing the
motherboard, please make sure you follow the instructions below:
Prepare a dry and stable working environment with
sufficient lighting.
Always disconnect the computer from power outlet
before operation.
Before you take the motherboard out from anti-static
bag, ground yourself properly by touching any safely
grounded appliance, or use grounded wrist strap to
remove the static charge.
Avoid touching the components on motherboard or the
rear side of the board unless necessary. Hold the board
on the edge, do not try to bend or flex the board.
Do not leave any unfastened small parts inside the
case after installation. Loose parts will cause short
circuits which may damage the equipment.
Keep the computer from dangerous area, such as heat
source, humid air and water.

CHAPTER 4: RAID FUNCTIONS
NF720D A2G+
4.1 O
Supports Windows XP Home/Professional Edition, and Windows Vista.
PERATING SYSTEM
4.2 RAID ARRAYS
RAID supports the following types of RAID arrays:
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for
many applications.
RAID 1: RAID 1 defines techniques for mirroring data.
RAID 0+1: RAID 0+1 combines the techniques used in R AID 0 and RAID 1.
RAID 5: RAID 5 provides fault to lerance and better utilizat ion of disk capacity.
4.3 HOW RAIDWORKS
RAID 0:
The controller “stripes” data across multip le drives in a RAID 0 array system. It breaks
up a large file into smaller b locks and performs disk reads and writes across multiple
drives in parallel. The size of each block is determined by the stripe size parameter,
which you set during the creation of the RAID set based on the system environment.
This technique reduces overall disk access time and offers high bandwidth.
Features and Benefits
- Drives: Minimum 2, and maximum is up to 6 or 8. Depending on the
platform.
- Uses: Intended for non-critical data requiring high data throughput, or any
environment that does not require fault tolerance.
- Benefits: provides increased data throughput, especially for large files.
No capacity loss penalty for parity.
- Drawbacks: Does not deliver any fault tolerance. If any drive in the array
fails, all data is lost.
- Fault Tolerance: No.
Block 1
Block 3
Block 5
Block 2
Block 4
Block 6
19
Page 22
Motherboard Manual
RAID 1:
Every read and write is actually carr ied out in paralle l across 2 disk drives in a RAID 1
array system. The mirrored (backup) copy of the data can reside on the same disk or on
a second redundant drive in the array. RAID 1 provides a hot-standby copy of data if
the active volume or drive is corrupted or becomes unavailable because of a hardware
failure.
RAID techniques can be applied for high-ava ilability solutions, or as a form of
automatic backup that eliminates tedious manual backups to more expensive and less
reliable media.
Features and Benefits
- Drives: Minimum 2, and maximum is 2.
- Uses: RAID 1 is ideal for small databases or any other application that
requires fault tolerance and minimal capacity.
- Benefits: Provides 100% data redundancy. Should one drive fail, the
controller switches to the other drive.
- Drawbacks: Requires 2 drives for the storage space of one drive.
Performance is impaired during drive rebuilds.
- Fault Tolerance: Yes.

Page 23
NF720D A2G+
RAID 0+1:
RAID 0 drives can be mirrored usin g RAID 1 techniques. Resulting in a RAID 0+1
solution for improved performance plus resiliency.
Features and Benefits
- Drives: Minimum 4, and maximum is 6 or 8, depending on the platform.
- Benefits: Optimizes for both fault tolerance and performance, allowing for
automatic redundancy. May be simultaneously used with other RAID
levels in an array, and allows for spare disks.
- Drawbacks: Requires twice the available disk space for data redundancy,
the same as RAID level 1.
- Fault Tolerance: Yes .

Motherboard Manual
RAID 5:
RAID 5 stripes both data and parity information across three or more drives. It writes
data and parity blocks across all the drives in the array. Fault tolerance is maintained
by ensuring that the parity informat ion for any given block of data is placed on a
different drive from those used to store the data itself.
Features and Benefits
- Drives: Mini mu m 3.
- Uses: RAID 5 is recommended for transaction processing and general
purpose service.
- Benefits: An ideal combination of good performance, good fault tolerance,
and high capacity and storage efficiency.
- Drawbacks: Individual block data transfer rate same as a single disk.
Write performance can be CPU intensive.
- Fault Tolerance: Yes .

Troubleshooting POST BIOS Beep Codes
Number of Beeps Troubleshooting Action
1, 3 Reseat the memory, or replace with known good modules.
Fatal error indicating a serious problem with the system.
Consult your system manufacturer. Before declaring the
motherboard beyond all hope, eliminate the possibility of
interference by a malfunctioning add-in card. Remove all
expansion cards except the video adapter.

z If beep codes are generated when all other expansion
cards are absent, consult your system manufacturer’s
technical support.
z If beep codes are not generated when all other expansion
cards are absent, one of the add-in cards is causing the
malfunction. Insert the cards back into the system one at a
time until the problem happens again. This will reveal the
malfunctioning card.
If the system video adapter is an add-in card, replace or
reseat the
video adapter. If the video adapter is an integrated part of the
system board, the board may be faulty.

5.5 TROUBLESHOOTING
Probable Solution
1. No power to the system at all
Power light don’t illuminate, fan
inside power supply does not turn
on.
2. Indicator light on keyboard does
not turn on.
System inoperative. Keyboard lights
are on, power indicator lights are lit,
and hard drive is spinning.
System does not boot from hard disk
drive, can be booted from optical drive.
System only boots from optical drive.
Hard disk can be read and applications
can be used but booting from hard disk
is impossible.
Screen message says “Invalid
Configuration” or “CMOS Failure.”
Cannot boot system after installing
second hard drive.
1. Make sure power cable is
securely plugged in.
2. Replace cable.
3. Contact technical support.
Using even pressure on both ends of
the DIMM, press down firmly until the
module snaps into place.
1. Check cable running from disk to
disk controller board. Make sure
both ends are securely plugged
in; check the drive type in the
standard CMOS setup.
2. Backing up the hard drive is
extremely important. All hard
disks are capable of breaking
down at any time.
1. Back up data and applications
files.
2. Reformat the hard drive.
Re-install applications and data
using backup disks.
Review system’s equipment. Make sure
correct information is in setup.
1. Set master/slave jumpers
correctly.
2. Run SETUP program and select
correct drive types. Call the drive
manufacturers for compatibility
with other drives.
