1. IntroductionofRAID

Thismotherboardadoptsa chipsetthatsupportsRAID.

Theterm“RAID”standsfor“RedundantArrayofInde-

pendentDisks”,whichisamethodofcombiningtwoor

moreharddiskdrivesintoonelogicalunit.Foroptimal

performance,pleaseinstallidenticaldrivesofthesame

modelandcapacitywhencreatingaRAIDset.Thefol-

lowingarecommonexamplesofRAID.Pleasereferto

theusermanualforthetypesofRAIDyourmotherboard

supports,andnoticethatotherrequirementssuchasa

RAIDsupportingdiskdriveandoperatingsystemare

alsocrucialforcreatingaRAIDvolume.

RAID 0 (Data Striping)

RAID0iscalleddatastripingthatoptimizes

twoidenticalharddiskdrivestoreadand

writedatainparallel,interleavedstacks.

Itwillimprovedataaccessandstorage

sinceitwilldoublethedatatransferrateof

asinglediskalonewhilethetwoharddisks

performthesameworkasasingledrive,

butatasustaineddatatransferrateandit

hasnofaulttolerance.

RAID 1 (Data Mirroring)

RAID1iscalleddatamirroringthatcopies

andmaintainsanidenticalimageofdata

fromonedrivetoaseconddrive.Itpro-

videsdataprotectionandincreasesfault

tolerancetotheentiresystemsincethe

diskarraymanagementsoftwarewilldirect

allapplicationstothesurvivingdriveasit

containsacompletecopyofthedatainthe

otherdriveifonedrivefails.

RAID 10

RAID10isastripedcongurationwithRAID1seg-

mentswhosesegmentsareRAID1arrays.Thiscon-

gurationhasthesamefaulttoleranceasRAID1,and

hasthesameoverheadforfault-toleranceasmirroring

alone.RAID10achieveshighinput/outputratesby

stripingRAID1segments.Insomeinstances,aRAID

10congurationcansustainmultiplesimultaneousdrive

failure.Aminimumoffourharddiskdrivesisrequired

forthissetup.

RAID 5

RAID5stripesbothdataandparityinformationacross

threeormoreharddiskdrives.Amongtheadvantages

ofRAID5congurationincludebetterHDDperfor-

mance,faulttolerance,andhigherstoragecapacity.

TheRAID5congurationisbestsuitedfortransaction

processing,relationaldatabaseapplications,enterprise

resourceplanning,andotherbusinesssystems.Use

aminimumofthreeidenticalharddiskdrivesforthis

setup.

RAID Conguration Precautions

1. Pleaseusetwonewdrivesifyouarecreating

aRAID0(striping)arrayforperformance.Itis

recommendedtousetwoSATAdrivesofthe

samesize.Ifyouusetwodrivesofdifferent

sizes,thesmallercapacityharddiskwillbethe

basestoragesizeforeachdrive.Forexample,

ifoneharddiskhasan80GBstoragecapa-

cityandtheotherharddiskhas60GB,the

maximumstoragecapacityforthe80GB-drive

becomes60GB,andthetotalstoragecapacity

forthisRAID0setis120GB.

2. Youmayusetwonewdrives,oruseanexi-

stingdriveandanewdrivetocreateaRAID1

(mirroring)arrayfordataprotection(thenew

drivemustbeofthesamesizeorlargerthan

theexistingdrive).Ifyouusetwodrivesofdiffe-

rentsizes,thesmallercapacityharddiskwill

bethebasestoragesize.Forexample,ifone

harddiskhasan80GBstoragecapacityand

theotherharddiskhas60GB,themaximum

storagecapacityfortheRAID1setis60GB.

3. Pleaseverifythestatusofyourharddisksbe-

foreyousetupyournewRAIDarray.

4. Pleasebackupyourdatarstbeforeyoucre-Pleasebackupyourdatarstbeforeyoucre-

ateRAIDfunctions.Intheprocessyoucreate

RAID,thesystemwillaskifyouwantto“Clear

DiskData”ornot.Itisrecommendedtoselect

“Yes”,andthenyourfuturedatabuildingwill

operateunderacleanenvironment.

2.1 Install the hard disk drives

Connecttwoormorenewharddiskdrivesofthesame

modelandcapacitytoyoursystem.

 BeforecreatingaRAIDarray,pleasechecktheusermanualfor

informationof:

 1.WhatlevelsofRAIDdoesyourmotherboardsupport

 2.WhichSATAportssupportRAID

 3.Otherrelatedrequirements

2.2 Set up UEFI

 StorageConguration.Set“SATAModeSelection”to

[RAID].

2.3 Congure Intel RAID BIOS

Rebootyourcomputer.Press<Ctrl+I>toentertheRAID

BIOSwhenyouseetheRAIDsoftwarestatusscreen.

 SelecttheoptionCreate RAID Volumeandpress

<Enter>.

 IntheCreateVolumeMenu,pleaseinsertaunique

nameforyourRAIDvolume.

 SelectyourdesiredRAIDLevel.

 IfyouselectedRAID0(Stripe),youarerequired

to select the stripe size for your RAID 0 array.The

availablevaluesrangefrom8KBto128KB.Thedefault

selection is 128 KB. The strip value should be chosen

basedontheplanneddriveusage.

•8/16KB-lowdiskusage

•64KB-typicaldiskusage

•128KB-performancediskusage

 Aftersettingstripsize,setthediskCapacity.

 Press <Enter> and then Press <Y> to continue when

theutilitypromptsaconrmationmessage.

 Aftertheconfiguration,youwillseethedetailed

informationabouttheRAIDarraythatyousetup.

 Pleasenotethatyou areonlyallowedto createoneRAID

partition at a timeunder BIOS RAID.If you want tocreate

anextraRAIDpartition, pleaseusetheRAIDutility under

WindowstocongureRAIDafteryouinstalltheOS.

 IfyouwanttodeleteaRAIDvolume,pleaseselectthe

option Delete RAID Volume, press <Enter>, and then

followtheinstructionsonthescreen.

3. Installing Windows® 8 / 8 64-bit / 7 / 7 64-bit

/ VistaTM / VistaTM 64-bit / XP / XP 64-bit on a

HDD in RAID mode

 AftertheUEFIandRAIDBIOSsetupyoumaystart

installingWindows® 8 / 8 64-bit / 7 / 7 64-bit / VistaTM /

VistaTM 64-bit / XP / XP 64-bit OSasusual.
