Yintoni uMlawuli we-RAID: Ukuqonda uLawulo loGcino

I-RAID 0: Ukuqhawula

I-RAID 1: Isipili

Indima kunye nokusebenza kwabalawuli be-RAID

Abalawuli be-RAID bangundoqo kwi ukulawula iinkqubo zokugcina. Baphatha ukuseta i-RAID, beqinisekisa ukuba yonke into ihamba kakuhle.Oku kubandakanya imisebenzi yolawulo logqogqo, ulawulo logqogqo, uqwalaselo lohlaselo, kunye nokuseta uhlaselo.

Embindini womsebenzi wabo ukulawula uluhlu lwediski. Basasaza idatha kuzo zonke iidrives ukuze basebenze ngcono kwayeukhuseleko. Ngamanqanaba e-RAID afana ne-RAID 0, i-RAID 1, kunye ne-RAID 5, igcina idatha ikhuselekile kwaye ikhulise ukugcinwa.

Abalawuli be-RAID balawula ukuhanjiswa kwedatha, ukubethelwa, kunye nesipili.

Bajonga impilo eqhubayo, balawule iidrive ezisecaleni, kwaye balungise ezo zingaphumelelanga.

Bakwasebenzisa i-caching ukukhawulezisa ufikelelo lwedatha, benze iisistim zikhawuleze.

Abalawuli be-RAID nabo babalulekile ukuseta nokulawula ugcino. Banikezela ngezixhobo ezilula ukusebenzisa izixhobo ze-IT ukuseka amanqanaba e-RAID kunye nokujonga impilo yokugcina.

"Abalawuli be-RAID ngamagorha angaziwayo kwiinkqubo zanamhlanje zokugcina, ukuqinisekisa ukhuseleko lwedatha, ukusebenza, kunye nokwandiswa."

Ngokudibanisa imisebenzi yokulawula uhlaselo kunye nolawulo lokugqogqa, aba balawuli banceda amashishini enze izisombululo ezinamandla, zokugcina ngokukhawuleza.

Iindidi zabalawuli be-RAID

I-RAID (i-Redundant Array of Independent Disks) abalawuli zingundoqo zokugcina idatha kunye nokuphindaphinda. Balawula iinkqubo ze-RAID, ukuqinisekisa ukhuseleko lwedatha kunye nokusebenza okungcono. Kukho iindidi ezimbini eziphambili: abalawuli be-RAID ye-hardware kunye nabalawuli be-RAID be-software.

Abalawuli be-RAID ye-Hardware

Abalawuli be-RAID be-Hardware zixhobo ezikhethekileyo ezilawula imisebenzi ye-RAID. Zikwi-motherboard okanye njengekhadi le-RAID. Olu seto lwenza imisebenzi ye-RAID isebenze ngaphandle kokucothisa ikhompyuter.

Izibonelelo zabalawuli be-RAID ye-hardware ziquka:

Ukuphuculwa kokuthembeka kunye nokukhuselwa kwedatha

Faster RAID uluhlu lwakhiwe ngokutsha

Ukuhambelana noluhlu olubanzi lweenkqubo zokusebenza

Ukukwazi ukusingatha ulungelelwaniso oluntsonkothileyo lweRAID (umz., iRAID 5, RAID 6)

Abalawuli beRAID yeSoftware

Abalawuli be-RAID beSoftware balawulwa ngenkqubo yokusebenza. Basebenzisa i-CPU yekhompyuter kwimisebenzi ye-RAID. Oku kunokucothisa inkqubo, ngakumbi kwimisebenzi enzima.

Izibonelelo zabalawuli be-RAID besoftware ziquka:

I-1.Ixabiso eliphantsi xa kuthelekiswa nabalawuli be-RAID ye-hardware

2. Ukulula kokuphunyezwa kunye nokulawula

3.Ukuhambelana noluhlu olubanzi lwee-hardware zoqwalaselo

Ukukhetha phakathi kwehardware kunye nesoftware yeRAID controller kuxhomekeke kwiimfuno zesistim yakho. Qwalasela ukusebenza, ukungafuneki kwedatha, kunye nohlahlo lwabiwo-mali. Ukwazi amandla kunye nobuthathaka bohlobo ngalunye kunceda ukwenza ukhetho olufanelekileyo kwiimfuno zakho.

Izibonelelo kunye neengxaki zabalawuli be-RAID

Abalawuli be-RAID banezibonelelo ezininzi ezenza zidume ukugcina nokulawula idatha. Enye into enkulu kukuphucula ukusebenza kohlaselo. Ukuseta iRAID kunokwenza ufikelelo lwedatha ngokukhawuleza ngokusasaza kwiidiski ezininzi. Oku kuhle kwimisebenzi efuna ukufikelela ngokukhawuleza kwedatha.

Enye inzuzo ephambili kukwandiswa kwedatha kunye nokhuseleko. Iinkqubo zeRAID zikhusela idatha ngokuyijonga okanye ukuyikrola kwiidiski. Oku kuthetha ukuba idatha ihlala ikhuselekile nokuba idiski iyasilela. Yinto enkulu kunye namashishini angakwaziyo ukulahlekelwa yidatha.

Kodwa, abalawuli be-RAID nabo banezinye iimeko ezisezantsi. Omnye umba ophambili kukunyuka kweendleko zehardware kunye nesoftware efunekayo. Ukuseta kunye nokulawula iinkqubo ze-RAID kunokuba nzima. Oku kunokufuna izakhono ezizodwa okanye uncedo lwe-IT.

Ukukhetha ukusebenzisa umlawuli we-RAID kufuneka kube sisigqibo esicingayo. Kubalulekile ukuvayisha iinzuzo ngokuthelekisa nezinto ezingahambi kakuhle. Oku kuya kunceda ukuqinisekisa ukuba iyahlangabezana neemfuno zombutho wakho.
