Summary ofRAIDConfigurations
RAIDArrays
ThissectiondescribesthefollowingtypesofRAIDarrays thatNVIDIARAID
supports:
RAID0
RAID0defines adisk stripingschemethatimprovesthe diskreadandwrite

RAID1
RAID1defines techniques formirroring data.
RAID0+1
RAID0+1 combines thetechniques usedinRAID0and RAID1arrays.
Spanning(JBOD)
JBOD provides amethod forcombining drives ofdifferentsizes intoonelarge
disk.
RAID5

NVIDIARAIDoffersthefollowing additionalfeatures:
Free Diskand DedicatedSpare Disk
AFreeDiskor DedicatedDisk canbeautomaticallyusedincaseone drive ofafault-
tolerantarrayfails.NVIDIARAIDdefines afault-tolerantarrayas eitherRAID1or
RAID0+1. Afreediskcanbeusedbyanyavailablefault-tolerantarray,whilea
dedicateddiskcanbeusedonlybythe arraytowhichitisassigned.
RAIDAcross PATAand SATA
NVIDIARAIDcan spanacrossbothParallelATAas well as SerialATA controllers.
RAIDoperations can beperformed onParallel ATAharddrives,SerialATAhard
drives,orbothParalleland Serial ATAharddrives.
BootableRAID
NVIDIARAIDcanbe configured inawaytomakeit bootable. Forexample, twohard
drives canbeconfiguredasabootablemirroredRAIDarray.
RAIDonMultipleDiskControllers
UnlikeotherRAIDsolutions thatlimitstheusertoadedicated RAIDcontroller,
NVIDIARAIDsoftwarecanuseadriveon oneRAIDcontroller and another driveon
asecond RAIDcontroller.
Morphing
Morphing istheabilitytoconvert fromoneRAIDmodetoanotherRAIDmode.This
allowstheuser toupgradetheircurrent diskorarrayfor betterperformance,higher
security,andincreasedcapacity.Moreimportantly,thisisaccomplishedwithout
having togo through multiplesteps.Themorphing featuregives theuseran
upgradeableoptiontomanage storageeasily.
HotPlug Array
Hotplug,withrespect toRAID, isthe abilitytoaddadisk toasystemsafelyand
withoutcausingproblemsfortheRAIDsoftware. Forexample,whenadrive ina
mirroredarrayfails, auser canlaunch the HotPlug ArrayWizardwhichinstructsthe

BasicConfigurationInstructions
Thefollowing arethebasicstepsfor configuring NVIDIARAID:
Non-BootableRAIDArray
1.ChoosetheharddisksthataretobeRAIDenabledinthesystemBIOS.
2.Specifythe RAIDlevel,eitherMirroring(RAID1),Striping(RAID0),Stripe Mirroring
(RAID0+1), Spanning (JBOD), orRAID5and createthedesiredRAIDarray.
3.Install theoperating systemon one harddisk,thenrebootthecomputer.
4.Run theWindowsnForceSetup application and installtheRAIDdriver.
5.Initialize theNVRAIDArray.
BootableRAIDArray
1.ChoosetheharddisksthataretobeRAIDenabledinthesystemBIOS.
2.Specifythe RAIDlevel, eitherMirroring (RAID1), Striping(RAID0),MirroredStrip-
ing (RAID0+1), Spanning (JBOD),or RAID5andcreatethedesiredRAIDarray.
3.BootfromtheWindowsCD,thenpress F6 whentheWindowsSetup appears.
