SAS Server HDD: Xidhmaha Khazanka ee Dakhliyadda ee Computing Iyo Data Centers

Qabyada SAS server HDD waxay leeyihiin jilood qalabka badan oo la xidhaa in la ilaa cimriyadii muhimma. Qabyida waxay leeyihiin koobiyar codsi ee caasiga ah (ECC) oo sax ugu dagaal ama wargelin karta xalalka xogta waqtigan, sidii xogta loo helay ama lacagga lagu bilaabo. Aljebirta waxay leeyihiin algorismood caasiga ah oo doorsooma joogto iyo awoodda qabyida, ogaanshada arrinkuna waxaa ka hor inta ay xogta u degganaan karto. Qabyidaas waxay dhammaan kartaa nidaamka adeegsiga ee hardware, abuuriya saaxiib labaad oo xogta muhimma. Tallaabada gudaha laba-wayn oo kale wuxuu siinayaa awood la iibsanayo, iyadoo la isku halgeliyo xogta ay ku jiraan haddii mid ka midka soo socodka way ciqaataa.

Qudhuhu in la xidhibayaa ee SAS server HDD-oyinka waxa lagu soo saaray si ay u fuliso hawlaha qumeeynta ee dakhliyada. Xawaadaha isdhaafidda ee dhammaan 15,000 RPM iyo algorismoodka cache ee kor u qaadaya waxaa leedahay jiritaanka arrabta iyo kaalinta hooseysa. Nidaamka SAS wuxuu ogolaanshahay in la isticmaalayo geesle aan oo kala duwan, sidoo kale midkaba ogolaanshahay in la beddelo arrabta iyo maareynta kor u qaadaya ee sharciga badnaa ee shaqooyinka. Dhaqaalkuna heli karaa geeslan oo walba la xiriira foomka iyagoo muuqda ah, taasoo gaar ah ee awoodlaha virtualized iyo banciyada arrabta ee ugu badnaya geeslan. Qaabka la taliyay waxa caddaanaysaa heerarka in ay ku darayso qodobka arrabtada iyagoo laakiin wax kasta oo la xidhibayaa heerarka caadiya ee arrabtada.

SAS server HDD-oyinka waxaa saddexmaya komponentiyada ee dakhliyadda oo aasaasiya loo design garay in la iska leeyahay amshaqada joogta ah ee ku jirta server-ka xadgudbiyaha. Wixii mekanka leh waxaa ka mid yaryarida nidaamka nijaasnimada oo ay ugu caddeeyaan sababta sababto ah ee ka soo jawaabto qalabka. Dhaqaan-kan waxaa lagu sameeyay iftiimada caawinaad si ay u helayaan inay daqan tahay ciduna iyo kala duwanaanshaha shidda ee ka soo jeedda data center-ka ee dakhliyadda. Muddada celceliska u dhaxaysa falshada (MTBF) wuxuu ka waynaa qiimaha dhaqaan ee consumer-grade, oo aan u bixin doono arrintiisa iyo kordhinta faa'iidooyinka. Dhaqaankan waxaa leh tajirro qorsheeda ee xaaladda arrintiisa oo kale ee arrintiisa, taasoo kesiibsan arrin cabsiye iyo kordhinta mowduumaha falshada.
