ukwesekwa kwe RAID ye-server HDD

Ukusekwa kweHDD yomncedisiyo yindlela encinane yesicelo samathuba apho kuhlanganiswa izinhdd ezingxenye ngokulandelana nevelo elilodwa ukuze kube nemibalula ematheni nokuphepha kwedatha. Le ndlela enhle ukusebenza kwezinhloso ezahlukene, kusuka ekuchazeni kumboniso ukuya kweqile ukunqamulela ngepari, ukuqiniseka ukuthi ikhona idatha fakwe kabusha nokuthola/beka amaspeedi ngemiphumela. Le teknoloji inemigomo yokuphatha i-controllers eyenzelwe ukuphatha ukwahlukaniswa kwedatha phakathi kwezinye i-drives, ngokuzenzakalelayo ukwenza umhlaba wokulungisa nokubuyisa imiphumela. Ukusekwa kweHDD yomncedisiyo kusebenza ngemigomo ye-hardware esebentayo noma izincazo zesoftware, ukunikeza ukuguqulwa kwebandla olufanele kuzo zonke izimo zomncedisiyo. Le ndlela iyagcina ukulondoloza ubomi bendawo, iyasebenza ngemiphumela yokubangela kabusha lapho kudingeka, iyakhumbula intetho yedatha ngemigomo engcono yokuhlola amaphoyinti. Le ndawo isetshenziswa kakhulu kumaqhakaza apho kuthiwani ukutholakala kwedatha nokusebenza kwesicelo siyinkimbinkimbi. Le teknoloji nakusekwa ukuthi isekwa, ikuvumela ukuthi i-drive ibutshelwe ngaphandle kokuthintana nomoya, kunye nenkqubo yabuciko yokuthuthukisa ukuxhumana nendawo.

Ukusekwa kweHDD RAID kuseva ikhona lezinhlekelelo eziningi ezingcono ezingcono esenza kube yimali yezindaba zasevisi nezinhlelo zokusebenza. Okokuqala, kungenzeka ukuvikela amadatha ngokukhona kwegqanti, esenza ukuqinisekisa ukusebenza kwevisi noma lapho iHDD evela. Inhlelo ikhona ukuthuthukiswa kokuwala nokubhala amadatha ngokwesithile ngokuhlela amadatha kuzinye izinhlelo, ngokusebenza kakhulu ukuthothelwa kwekhasimende. Ukunciphisa izindleko ikhona ngokuthuthukiswa koku sebenzisa izicathami nekhono lokusebenzisa izinhlelo zeHDD ezijwayelekile futhi zilinde isebenza sasevisi. Inhlelo ikhona ukuthuthukiswa kweyona, esenza amakhiwa ukuthola amadatha ngaphansi kwekhasimende noma ukuthola ukusebenza noma ukuthola ukuvikela. Ukusekwa kwekhiya yindlela enye yokuthola ukuthuthukiswa, nezinhlelo zokuphatha kanye nezinhlelo zokulandela ukuthola ukuthola ukusebenza kwekhiya. Ukusekwa kwekhiya kanye nekhono lokuguqula iHDD esenza kube yimali yekhasimende yekhasimende. Ngaphezulu, ukuthuthukiswa kweRAID ikhona ukuthuthukiswa kwekhasimende, ukuthuthukiswa kweyona nekukhona kwegqanti, esenza amakhiwa ukuthi ayilinde izidingo zabo. Inhlelo ikhona ukusekwa kokuqinisekisa amadatha ngenyakaza futhi kuthole ukuthi amadatha ayilinde isebenza. Kumaqo ehandlela amadatha ephatheni, ukusekwa kwemvume ikhona ukuthuthukiswa kweyona ngaphandle kokudinga ukusebenzisa izinhlaka eziningi. Ukusekwa kwekhiya kanye nekhono lokuthatha amadatha ngenyakaza kumele kuthole ukusebenza kwekhasimende futhi kuthole isikhathi sokuthola amadatha.

Ukugcina Wezulu Nokubonakala Okuphambene

Uhlelo lokusekela i-HDD RAID lweseva lusebenzisa izindlela eziyinkimbinkimbi zokuvikela idatha ngokusebenzisa izingqimba eziningi zokuphindaphinda. Isebenzisa ama-algorithms athuthukile ukusabalalisa idatha kuma-drive ngamaphethini aqinisekisa amakhono okubuyisela emuva ngisho nasezimweni eziningi zokwehluleka kwe-drive. Uhlelo luqhubeka luhlola ukuvumelana kwezinto, lubone futhi lungise izinkinga ezingase zibe khona ngaphambi kokuba zithinte ubuqotho bedatha. Le ndlela yokuvikela idatha ihlanganisa ukutholakala kwamaphutha ngesikhathi sangempela nokulungiswa kwawo, ukwakhiwa kabusha kwe-drive okuzenzakalelayo, kanye nokusabalalisa kabusha idatha ngokuhlakanipha lapho kwenzeka ukwehluleka. Lobu buchwepheshe buhlanganisa izinqubo zokuhlola eziphambili nokuqinisekisa ukuvimbela ukonakala kwedatha ethule, okuqinisekisa amazinga aphezulu kakhulu okuthembeka kwedatha.

Ukudizayna Okuthuthake Isisebenzi

Ukucwangcwa kwezinhloso zokusebenza ze-server HDD RAID ukwesekwa yindlela yokwenza ngokuholela kakhulu kuzindleke zokusebenza. Unezimigca evelayo zokugcina okuphathelene nokubaluleka nokulayisha, kubusa ukungabi nangcono ukukhiye kwedatha. Isisitemu inemigca emikhulu ye-scheduling ye-I/O eyiphiqela imisebenzi esenza ngaphandle kokulandelana ne-engagement yezinhloso. Iziphumo ezinhle zokulinganisa kanye nezilayisho zenkulungelo kungenxa yokuthi kungenhla ukusebenza ngokuvamile kuzindleke ezahlukene. Ukucwangcwa kunemigca elula yokufunda-kuqala okuphawula futhi kubeke datha ngaphambi kokuba kuthathwe basebenzisa izindikimba, lokhu kungenhla ukuphendula kwezinhloso.

Ukuphathwa Okumiselwe Nezibophelo

Ukusekwa kweHDD kwiRAID kwiiseva ikunikeza imininingwano yokuphatha okubhekelela kakhulu elweni lokusebenzela kwezinhlangano. Lo mbhalansi uphakathi kwezivumelwano ezifanelekileyo ukuseta nokuhlinza, kube lapho abasebenzisi bakwenzela ukuphatha izinkomba eziphezulu zokugcinwa. Iyasekela ukulandelela kwesayizi futhu kwezinto zeRAID ngenxa yokuqhutshiswa kweRAID ngaphandle kokudinga ukuthi isisitemi sikhude. Isicathami sokuphatha sinemibono encane encane nezinsiza zokuhlinza okunikeza amanqaku ohlelweni wokusebenza kwesicathami sokugcinwa. Izici ezijwayelekileyo zokuzothekisa ukwenza izindaba ezijwayelekileyo njengekuqala kwekhilomitha, ukuvula futhu, nokulandelana kwesayizi, kulula ukuphathwa futhu kuyahlisa impilo yokwenza amaphutha.
