Array weerar - xalinta dhibaatooyinka la akhrin / xawaaraha qortaa iyo isku halaynta of nidaamka

Weerar isugu soo diyaariyeen - waa dhowr drives labada madax banaan, kuwaas oo isku xidhan by channels ka hawlgala xawaare ku filan sare. Nidaamka qaadataa ururka this hal a disk soo diyaariyeen. Maareynta qaybinta akhriska iyo qorista habka loo sameeyaa by dirato.

Weerar isugu soo diyaariyeen waxaa loo isticmaalaa si loo kordhiyo xawaaraha lagu qoro ama isku halaynta of kaydinta disk ah. Xalka of arrimahan si weyn u marin kara tayada guud ee nidaamka oo dhan.

Markii hore, abuurka ah ee weerar-soo diyaariyeen ku lug dhaafka saxannada jaban. initiative Tani waxay si cad ka muuqata horyaalka (gaabiyay waxay ka dhigan tahay waxa soo socda: "Array siyaado ah saxannada jaban"). Laakiin markaas, technology this cadeeyay inuu yahay tayo leh oo lagu kalsoonaan karo, loo bedelay. weerar isugu soo diyaariyeen Modern loo abuuray, sida caadiga ah, ku salaysan qalabka si caddaalad ah u qaali ah. Tani, markeeda, waxaa mar kale ka muuqataa in horyaalka (hadda taagan tahay "Array siyaado ah saxannada Independent").

horumarinta bulshada macluumaad ah si xoog leh u saameeyay shuruudaha la hormarsataan in hardware ah, oo ay ku jirto dukaamada xogta. Sidaa darteed, inta weerar-soo diyaariyeen waxaa la abuuray, waxaa jiray podtehnology kala duwan, kaas oo lagu soosaaray si wax looga qabto hawlaha compartmentalized gaar ah.

All noocyo kala duwan oo ka mid ah dhibaatooyinka xalin by kombiyuutarada u baahan tahay kala duwan sida ugu badan ee xal technology. Arrays Noocyada weerar:

• Weerar-0. In hirgelinta fudud u baahan tahay laba drives. Info socda unit duubo jirsado labada drives. Reading ku jira geedi socod dambe. Tani waxay si weyn u dadajiyaa ilaa rikoorka, laakiin ma bixiso halaynta ku filan, maxaa yeelay, qalad ah oo ku saabsan mid ka mid ah cajaladood oo ay keenaysaa in khasaaraha of data soo diyaariyeen oo dhan.
• Weerar-1. In hirgelinta fudud u baahan tahay laba drives. macluumaadka lagu siiyey on cajaladood oo lagu duubay iyaga oo ku saabsan si buuxda. Tani waxay yaraysa habka wax lagu qoro, laakiin ay sabab u tahay shaqo buuxda siisaa heer sare ah isku halaynta. Faa'iidada ugu weyn ee horumarinta this - helitaanka sare oo u qoran si degdeg ah (maxaa yeelay, waxaa suurtagal ah in laga bilaabo laba drives isku mar ka akhriso).
• Weerar-5. soo diyaariyeen A eed-dulqaad. In hirgelinta fudud, waa in aad haysataa saddex saxannada. duubo Macluumaad kasta oo dhacaa jabiyay durdur xogta galay blocks, kuwaasoo mid walba uu waxa lagu qoray dalbatay ah. Haddii ay dhacdo in khasaaraha xogta ku saabsan mid ka mid ah cajaladood oo ah, aad u celinaynaa karaa iyadoo la isticmaalayo checksums diiwaan geliyay kale ah. Recovery u baahan qoondaynta awoodda weyn, sidaas darteed inta badan fulinta waxa la adeegsadaa on hardware server.

Weerar isugu soo diyaariyeen xaqiijinta shanaad waa kuwa ugu badan. Tan waxa u sabab ay isku halaynta iyo xawaaraha sare ee processing macluumaadka, tan iyo hal isugu diyaariyeen a waa la samayn karaa mar geedi socodka dhowr madax banaan qoro iyo macluumaad akhriska.
