I-RAID 10 Inkcazo kunye neengqwalasela zokuphunyezwa kwi-Mac yakho
Inkcazo
I-RAID 10 yinkqubo ye-RAID edibeneyo eyenziwe ngokudibanisa i-RAID 1 ne-RAID 0. Udibaniso luyaziwa njengomdlalo wezibuko. Kulo lungiselelo, idatha imida kakhulu njengoko kuluhlu lwe- RAID 0 . Ukwahlukana kukuba ilungu ngalinye leteti ezimiselweyo lidibene neenkcukacha zalo. Oku kuqinisekisa ukuba ukuba nayiphi na idrayivu enye kwindawo ye-RAID 10 ihluleka, idatha ayilahlekanga.
Enye indlela yokucinga ngohlobo lwe-RAID 10 lufana ne-RAID 0 ene-intanethi ye-intanethi nganye ye-RAID ekulungele ukuhamba, xa kufuneka i-drive iphumelele.
I-RAID 10 idinga ubuncinci bemoto emine kwaye inokwandiswa ngamabini; ungaba ne-RAID 10 kunye ne-4, 6, 8, 10, okanye ngaphezulu. I-RAID 10 kufuneka ibhalwe ngamatshini afanayo.
I-RAID 10 inzuzo ekusebenzeni ngokukhawuleza kokufunda. Ukubhalwa kwinqanaba kungancinci ngoba iindawo ezininzi ezibhala indawo kwindawo yamalungu kufuneka zifunyenwe. Nangona kubhala ukubhala, i-RAID 10 ayihlupheki kwizantya eziphantsi kakhulu ezibonwe ekufundeni okungahleliwe kwaye zibhala ngamazinga e-RAID asebenzisa ubunye, njengo-RAID 3 okanye RAID 5.
Awufumani ukusebenza okungahleliwe / ukubhala ngokukhululeka, nangona kunjalo. I-RAID 10 idinga ukuqhuba ngaphezulu; ezine kunye ubuncinane kunye nomithathu kwi-RAID 3 kunye ne-RAID 5. Ukongeza, i-RAID 3 ne-RAID 5 inokwandiswa idiski enye ngexesha, ngelixa i-RAID 10 idinga iidiski ezimbini.
I-RAID 10 yinto efanelekileyo yokugcina idatha ngokubanzi, kuquka ukukhonza njengomqhubi wokuqalisa, kunye nokugcinwa kweefayile ezinkulu, ezifana ne-multimedia.
Ubungakanani bobubanzi be-RAID 10 bungabalwa ngokuphindaphinda ubungakanani besitoreji esisodwa kwisigxina kwinani lokuqhuba kwi-array:
S = d * (1/2 n)
"S" ubukhulu be-RAID 10, "d" bubungakanani bokugcina besithuthi esincinane kunazo zonke, kwaye "n" yile nombolo yokuqhuba kwi-array.
RAID 10 kunye ne-Mac yakho
I-RAID 10 yinqanaba le-RAID elixhaswayo elifumaneka kwi-Disk Utility ukuya kwi-OS X Yosemite.
Ngokukhutshwa kwe-OS X El Capitan, i-Apple isuswe inkxaso ngokuthe ngqo kumanqanaba onke we-RAID ukusuka kwi-Disk Utility, kodwa usenokudala nokulawula i-RAID kwi-El Capitan kwaye kamva usebenzisa i-Terminal kunye nomyalelo we-appleRAID.
Ukudala uluhlu lwe-RAID 10 kwi-Disk Utility kufuna ukuba uqale wenze ezimbini ezimbini ze-RAID 1 (i-Mirror) , uze usebenzise njengoko imiqulu emibili ifakwe kwi- RAID 0 (Striped) .
Umcimbi owodwa nge-RAID 10 kunye ne-Mac edlalwa yinto efunekayo ukuxhasa inkqubo ye-RAID esekelwe yi-OS X. Ngaphandle kwexesha eliphezulu lokuba ne-OS X ilawulwe i-RAID, kukho isidingo sokuncinci ezine ezineendlela eziphezulu zokusebenza ze-I / O ukuxhuma ii-drive kwi-Mac yakho.
Izindlela eziqhelekileyo zokwenza uxhumano lusebenzise i- USB 3 , i- Thunderbolt , okanye kwimeko ka-2012 nangaphambili kwe-Mac Pros, ii-bay drive. Umba kukuba kwimeko ye-USB 3, amaninzi ama-Mac akanayo iirekhodi ezine ezizimeleyo ze-USB; Kunoko, bahlala bexhunyiwe kumlawuli omnye we-USB okanye ababini, ngoko ke baqamba amaninzi amachwephethi e-USB ukuba babelane ngezixhobo ezikhoyo kwi-chip controller. Oku kunokunciphisa ukusebenza okungenzeka kwe-software-based RAID 10 kuma-Macs amaninzi.
Ngelixa kunesiphelo esiphezulu se-bandwidth ekhoyo, i-Thunderbolt isenokukwazi ukuba neengxaki zingaphi ii-Thunderbolt ezichwebeni kwi-Mac yakho zilawulwa ngokuzimela.
Kwimeko ye-2013 Mac Pro, kukho iinqwelatho ezithandathu ze-Thunderbolt, kodwa kuphela abalawuli abathathu beThunderbolt, umlawuli ngamnye olawula ukuhamba kwedatha kwiichweba ezimbini zeThunderbolt. I-MacBook Airs, i-MacBook Pros, i-Mac minis, kunye neMacs zonke ziphethe umlawuli omnye weThunderbolt ezabelwana kunye namachweba amabini eThunderbolt. I-exception yeyona micimbi encinci iMacBook Air, ene-Port yeTynderbolt enye.
Enye indlela yokulwa nokunciphisa ububanzi bebhanti ebangelwa ngabalawuli ababiweyo be-USB okanye i-Thunderbolt ukusebenzisa i-RAID 1 esebenzayo kwi-hardware-based (i-Mirrored) yangaphandle, kwaye usebenzisa i-Disk Utility ukuhlula isibini sezibuko, ukudala uluhlu lwe-RAID olulodwa kuphela ifuna izibuko ezimbini ezizimeleyo ze-USB okanye ichweba elilodwa leThunderbolt (ngenxa ye-bandwidth ephezulu ekhoyo).
Kwaziwa njenge
RAID 1 + 0, RAID 1 & 0
