4.1.1 RAIDdenitions
Volumeprovidestheabilitytolink-togetherstoragefromoneorseveraldisks,regardless
ofthesizeofthespaceonthosedisks.Thiscongurationisusefulinscavengingspaceon
disksunusedbyotherdisksinthearray.Thiscongurationdoesnotprovideperformance
benetsordataredundancy,diskfailurewillresultindataloss.
RAIDABLEarrays(alsoknownasRAIDReady)areaspecialtypeofVolume(JBOD)that
allowstheusertoaddmorestoragespaceorcreatearedundantarrayafterasystemis
installed.RAIDABLEarraysarecreatedusingOptionROM,UEFI,orrcadm.
TheabilitytocreateRAIDABLEarraysmayvarypersystem.
RAID0(Datastriping)optimizestwoidenticalharddiskdrivestoreadandwritedatain
parallel,interleavedstacks.Twoharddisksperformthesameworkasasingledrivebutata
sustaineddatatransferrate,doublethatofasinglediskalone,thusimprovingdataaccess
andstorage.Useoftwonewidenticalharddiskdrivesisrequiredforthissetup.
RAID1(Datamirroring)copiesandmaintainsanidenticalimageofdatafromonedriveto
aseconddrive.Ifonedrivefails,thediskarraymanagementsoftwaredirectsallapplications
tothesurvivingdriveasitcontainsacompletecopyofthedataintheotherdrive.ThisRAID
congurationprovidesdataprotectionandincreasesfaulttolerancetotheentiresystem.Use
twonewdrivesoruseanexistingdriveandanewdriveforthissetup.Thenewdrivemustbe
ofthesamesizeorlargerthantheexistingdrive.
RAID 10isdatastripinganddatamirroringcombinedwithoutparity(redundancydata)having
