RAID 10 Lus Txhais thiab Cov Kev Ntsuam Xyuas Kev Xyaum Kom Ua Rau Koj Lub Mac
Txhais
RAID 10 yog ib qho RAID uas tau tsim los ntawm kev sib koom ua ke RAID 1 thiab RAID 0. Cov kev sib txuas ua ke yog hu ua ib lub iav ntawm tsom iav. Hauv kev kho no, cov ntaub ntawv yog txu ntau npaum li nws yog nyob rau hauv RAID 0 array. Qhov txawv yog hais tias txhua tus tswv cuab ntawm cov kab txaij muaj nws cov ntaub ntawv iav. Qhov no ua kom pom tau tias yog muaj tsav tsheb hauv RAID 10 array tsis tiav, cov ntaub ntawv tsis poob.
Ib txoj kev xav txog RAID 10 array yog ib qho RAID 0 nrog rau cov thaub qab hauv online ntawm txhua lub caij RAID npaj mus, yuav tsum tau tsav.
RAID 10 yuav tsum muaj tsawg kawg ntawm plaub drives thiab tuaj yeem ua rau ob leeg khub; koj tuaj yeem muaj RAID 10 array nrog 4, 6, 8, 10, lossis ntau dua. RAID 10 yuav tsum muaj kev sib npaug sib npaug.
RAID 10 kev pab cuam los ntawm kev nyeem ntawv ceev ceev. Sau ntawv mus rau array yuav qeeb me ntsis vim hais tias ntau qhov chaw sau ntawv nyob rau hauv cov tswv cuab ntawm array yuav tsum tau pom. Txawm nrog sau qeeb qeeb, RAID 10 tsis raug kev txom nyem los ntawm kev qis qis heev pom hauv kev nyeem ntawv thiab sau ntawm RAID qib uas siv parity, xws li RAID 3 los yog RAID 5.
Koj tsis tau txais qhov kev nyeem ntawv / kev sau ntawv random rau dawb, tab sis. RAID 10 yuav tsum tau tsav ntau dua; plaub yam tsawg kawg nkaus thiab peb rau RAID 3 thiab RAID 5. Ntxiv mus, RAID 3 thiab RAID 5 tuaj yeem txhab ib zaug ib zaug, hos RAID 10 yuav tsum muaj ob lub ploj.
RAID 10 yog kev xaiv zoo rau kev khaws cov ntaub ntawv, suav nrog kev ua haujlwm ua tsav pib, thiab khaws cia rau cov ntaub ntawv loj, xws li multimedia.
Tus RAID 10 array qhov luaj li cas yuav muab xam los ntawm kev muab tus tsav tsheb sib npaug loj loj los ntawm ib nrab ntawm cov naj npawb ntawm cov xov tooj:
S = d * (1/2 n)
"S" yog qhov loj ntawm RAID 10 array, "d" yog qhov loj me me ntawm cov tsav me tshaj plaws, thiab "n" yog tus naj npawb ntawm cov khoom nyob hauv cov khoom.
RAID 10 thiab koj lub Mac
RAID 10 yog ib qib RAID uas muaj nyob hauv Disk Utility mus txog OS X Yosemite.
Nrog rau kev tso tawm ntawm OS X El Capitan, Kua tshem kev them nyiaj yug rau txhua theem RAID hauv Disk Utility, tiam sis koj tseem tsim thiab tswj RAID arrays hauv El Capitan thiab tom qab siv Terminal thiab appleRAID hais kom ua.
Tsim lub RAID 10 array hauv Disk Utility kom koj yuav tsum xub tsim ob tog ntawm RAID 1 (Daim iav) cov arrays , thiab tom qab ntawd siv lawv li ob qho tagnrho mus rau hauv RAID 0 (Striped) array .
Ib qho teeb meem nrog RAID 10 thiab Mac uas feem ntau tsis saib xyuas yog qhov nyiaj bandwidth uas yuav tsum tau los txhawb qhov software raws li RAID uas siv los ntawm OS X. Tshaj ntawd cov nyiaj siv ntawm OS X tswj cov RAID array, kuj tseem xav tau qhov tsawg kawg nkaus ntawm plaub qib high-kev ua tau I / O raws mus cuag lub drives rau koj Mac.
Ntau txoj hauv kev los ua qhov kev sib txuas yog siv USB 3 , Thunderbolt , los yog thaum xyoo 2012 thiab Mac Advance dhau los, kev tsav tsheb sab hauv. Qhov teeb meem yog hais tias nyob rau hauv cov ntaub ntawv ntawm USB 3, feem ntau Macs tsis muaj plaub ywj siab USB ports; Xwb, lawv yog feem ntau txuas rau ib los yog ob tug USB 3 controllers, yog li yuam ntau USB chaw nres nkoj sib qhia cov kev pab muaj los ntawm ib tug ntiv tes nti. Qhov no tuaj yeem txo qhov kev ua tau zoo ntawm software-raws li RAID 10 ntawm Macs feem ntau.
Thaum nws muaj ntau ntau txoj kev muaj bandwidth muaj, Thunderbolt tseem muaj qhov teeb meem ntawm ntau npaum li cas Thunderbolt ports ntawm koj Mac yog tswj ntawm nws tus kheej.
Nyob rau hauv cov ntaub ntawv ntawm lub 2013 Mac Pro, muaj rau Thunderbolt ports, tab sis tsuas yog peb Thunderbolt controllers, txhua tus maub los tuav cov ntaub ntawv dhau los rau Thunderbolt cov chaw nres nkoj. MacBook Airs, MacBook Pros, Mac minis, thiab iMacs tag nrho muaj ib zaug xwb Thunderbolt maub los faib nrog ob Thunderbolt cov chaw nres nkoj. Qhov kos yog lub me MacBook Cua, uas muaj ib zaug xwb Thunderbolt chaw nres nkoj.
Ib txoj kev uas kov yeej cov kev txwv ntawm bandwidth los ntawm kev sib koom siv USB los yog Thunderbolt controllers yog siv ib tug khub ntawm RAID 1 (Mirrored) sab nraud, thiab siv Disk Utility rau lub iav tsom iav, tsim ib RAID 10 array uas tsuas yuav tsum muaj ob qhov ntawm USB ports lossis ib qho Thunderbolt chaw nres nkoj (vim yog qhov ntau dua bandwidth).
