I-RAID 10 Incazelo nokucatshangelwa kokuyisebenzisa kuMac wakho
Incazelo
I-RAID 10 iyisistimu ye-RAID eyakhiwe ngokuhlanganisa i-RAID 1 ne-RAID 0. Inhlanganisela yaziwa njengembono yezibuko. Kulo lungiselelo, idatha idutshulwa kakhulu kunombandela we- RAID 0 . Umehluko wukuthi ilungu ngalinye lesethi yemigqa linemininingwane yalo ekhonjisiwe. Lokhu kuqinisekisa ukuthi uma noma yikuphi ukushayela okukodwa ku-RAID 10 kuhluleka, idatha ayilahlekile.
Enye indlela yokucabanga ngohlobo lwe-RAID 10 njenge-RAID 0 ene-inthanethi yokulondoloza isici ngasinye se-RAID esilungele ukuhamba, uma i-drive ihluleka.
I-RAID 10 idinga ubuncane bama-drives amane futhi ingahanjiswa ngamabili; ungaba nohlu lwe-RAID 10 ngezingu-4, 6, 8, 10, noma ngaphezulu. I-RAID 10 kufanele ikhiqizwe ngokushayela okulinganayo.
Izinzuzo ezingu-RAID ezingu-10 kusukela ekusebenzeni okusheshayo okufundwayo. Ukubhalela ohlwini kungancipha kancane ngoba eziningi zokubhala izindawo kumalungu alandelayo kufanele zitholakale. Ngisho nokubhala kubambezela kancane, i-RAID 10 ayihlupheki ngokusheshiswa okuphansi kakhulu okubonwa ekufundeni okungahleliwe futhi kubhala ngamazinga we-RAID asebenzisa ubunye, njengo-RAID 3 noma RAID 5.
Awutholi ukusebenza okungahleliwe kokufunda / ukubhala mahhala, noma kunjalo. I-RAID 10 idinga ukushayela okwengeziwe; ezine njengenani eliphansi kanye no-3 nge-RAID 3 ne-RAID 5. Ngaphezu kwalokho, i-RAID 3 ne-RAID 5 inganwetshwa i-disk eyodwa ngesikhathi, kuyilapho i-RAID 10 idinga ama-diski amabili.
I-RAID 10 iyisinqumo esihle sokugcinwa kwedatha jikelele, kufaka phakathi ukukhonza njengomshayeli wokuqalisa, futhi njengesitoreji samafayela amakhulu, njenge-multimedia.
Usayizi we-RAID we-RAID 10 ungabalwa ngokuphindaphinda usayizi wesitoreji esisodwa wedeski ngesigamu inani lezinkomba ezihambweni:
S = d * (1/2 n)
"S" ubukhulu be-RAID 10, "d" yayizilinganiso yesitoreji yedrayivu encane kunazo zonke, futhi "n" iyinombolo yokushayela emgqeni.
I-RAID 10 ne-Mac yakho
I-RAID 10 iyinqanaba le-RAID elisekelwayo elitholakala ku-Disk Utility kuze kufike ku-OS X Yosemite.
Ngokukhululwa kwe-OS X El Capitan, i-Apple isuse ukusekelwa okuqondile kuwo wonke amazinga we-RAID avela ngaphakathi kweDisk Utility, kodwa usengakwazi ukudala uphinde uphathe izakhiwo ze-RAID ku-El Capitan futhi kamuva usebenzisa i-Terminal nomyalo we-appleRAID.
Ukudala uhlu lwe-RAID 10 ku-Disk Utility kudinga ukuthi uqale udale amabilidi amabili we-RAID 1 (Mirror) , bese uwasebenzisa njengoba imiqulu emibili ihlanganiswa ibe yi- RAID 0 (Striped) .
Inkinga eyodwa nge-RAID 10 kanye ne-Mac okuvame ukushiywa indiva inani le-bandwidth edingekayo ukusekela uhlelo lwe-RAID olusekelwe kwesofthiwe olusetshenziswa yi-OS X. Ngaphandle kwesihloko sokuba ne-OS X iphathe uhlu lwe-RAID, kunesidingo sokungenani yezine iziteshi ze-I / O ezinezinga eliphezulu zokuxhuma amashayela ku-Mac yakho.
Izindlela ezivamile zokwenza uxhumano zizosebenzisa i-USB 3 , i- Thunderbolt , noma kwenzeka ngo-2012 nangaphambili kwe-Mac Pros, ama-drive drive wangaphakathi. Inkinga iwukuthi esimweni se-USB 3, ama-Mac amaningi awanayo amachweba amane a-USB azimele; Kunalokho, bavame ukuxhumeka ku-one or two controllers USB, ngaleyo ndlela baphoqelela amathrekhi amaningi we-USB ukuze babelane ngezinsiza ezitholakalayo kusuka ku-chip controller. Lokhu kunganciphisa ukusebenza okusemandleni kwe-software-based RAID 10 kuma-Macs amaningi.
Ngenkathi ine-bandwidth enkulu kakhulu etholakalayo, i-Thunderbolt isengaba nenkinga yokuthi zingaki izikebhe ze-Thunderbolt ku-Mac yakho ezilawulwa ngokuzimela.
Endabeni ka-2013 Mac Pro, kunezingxenyana eziyisithupha ze-Thunderbolt, kodwa kuphela abalawuli beThunderbolt abathathu kuphela, isilawuli ngasinye sithatha ukudluliswa kwedatha kwamathuluzi amabili e-Thunderbolt. I-MacBook Airs, i-MacBook Pros, i-Mac minis, ne-iMacs bonke banomlawuli oyedwa we-Thunderbolt owabelane namachweba amabili we-Thunderbolt. Okuhlukile yi-MacBook Air encane, enechweba elilodwa le-Thunderbolt.
Enye indlela yokunqoba ukulinganiselwa komkhawulokudonsa obangelwa abalawuli be-USB noma i-Thunderbolt abahlanganyele ukusebenzisa i-RAID 1 (Mirredred) yokufaka yangaphandle, futhi sebenzisa iDisk Utility ukuhlubula izibuko, ukudala uhlu lwe-RAID olulodwa kuphela idinga amabhulokhi amabili e-USB ahlukene noma ichweba elilodwa le-Thunderbolt (ngenxa ye-bandwidth ephakeme etholakalayo).
Obeye aziwe njengo
I-RAID 1 + 0, RAID 1 & 0
