umehluli wehDD yekhombisi

Ispeedi ye-HDD yomncedisi iyisikwele esibalulekileyo kwiindawo zokugcinwa data, ikhetha ukuthini incazelo ingatholakala nokuthunyelwa ngaphandle kweenkqubo zokugcinwa ze-ndaba. Iindlela zaseva zamanziya asebenza ngemizuzwana okuphela kwiinkcukacha ezilandelanayo kwi-7,200 ukuya kwi-15,000 RPM, neempidhi eziphezulu zinika amandla ekufinyeleleni kwaye ukuthunyelwa kwe data ngokushesha. Ezi ndlela zibandakanya iitechonoloji ezininzi njenge-Tech ye-Dynamic Fly Height, enguqulela indawo yekhowudi yokufaka/ukucoca ngokuzenzekelayo ukuze ibe ngokuchanekileyo kunye nobulungiswa. Iindlela zaseva zanezicathami ezijikelezileyo, ngokuvumelana ne-128MB ukuya kwi-256MB, ezingenza impumelelo ekufinyeleleni kwe data ngokugcinwa kwezinto ezitholwa ngokuninzi. Imfanelo yee-HDD zaseva iqhiswa ngokusebenza kwezinye iziqingatha, kuxhomekeke kwiimpidhi zokufaka/ukucoca eziphezulu unguvu lokuwa kwi-250MB/s, kunye netime yokuvinjelwa apho kuyafika kwi-4ms. Iindlela zeendaba zaseva zinzignwa xa zisebenza ngokupheleleyo kuzimvelo eziphambene, nge-Rating ye-MTBF (Umbala wamaxesha phakathi kwii-failure) up to 2.5 million hours. Ezi ndlela zazithuba ukusebenzisa iimali zokulungisa amadloko kunye neenkcukacha zokugcinwa datha kunye nokukhusela iindlela ezipotiyelweyo. Iindlela zokusebenza kwee-HDD zaseva zizo zihlala ngokwanelekileyo kwiindlela ezidinga ukusebenza ngokutabile, njengoko kubalo le database, ukwinilela kweefayili, kunye neenkcukacha zokubeka khona.

Isantya se-HDD server ikunika amaphetho amaningi kuzo zindlela zokusebenza ezinhle. Okokuqala, izivivinyo eziphakeme zokugujula zenze ukuba ukufinyelela ne ukuthwala datha kube lula futhi kwehlise ukucima kwemishenini esenza ngokukhawuleza. Lokhu kwenza ukuba isantya sokuphendula kube lula xa kubekwa imibiko yedatha noma ukuhlela amafayela, okuwenza ukuba isantya sakudala sibe njengoba kudingeka. Izinkomba eziphezulu ezifakwe ku-HDD yamaseva zenze ukuba ukuthwala datha kube lula ngokwehlisa inani lezikhathi elidinga ukufinyelela fisikaly ekasi disk. Lezi diski ziphawula ukuba uyisusa kakhulu xa sebenza ngqo, lokhu kwenza wokuba yisimoto esenzakalelayo lapho kumele kube khona ukungena komsebenzi. Izindawo zokulungisa amaphoyinti okungenzeka akunciphisa amadatywayo aqedwa, futhi izinkomba zokulandela ukuthi kutheni zenze ukuba kube lula ukwenza amathuluzi aphambene nemingcele emisha. Ukuhlelwa kwemali kunye nelindlela zokunikeza amakhilobhayit ama-khombisa amancane ngokulinganisa nezinto ezinjenge-Solid State. Izenzo eziphezulu ze-engine ziyenza ukuba usebenze ngemva elaphayo, lokhu kwenza ukuba ikhishwa ngokushesha kwezimali ngokudala. Ngaphezu kwalokho, i-HDD yamaseva zinezinhlanhla zokuhlangana nezinhlanhla zezokusebenza zomthombo, lokhu kwenza ukuba iyihlakaniphiwe kakhulu endaweni etholakele. Teknoloji yawo enembile nekutsi inkimbini yasemadolobheni yenze ukuba ukulungiswa nokubuyiselwa kwezinto kube lula. Ukuxhumano phakathi kwebangela, ukususa nokuhlelwa kwemali kwenza ukuba isantya se-HDD server ikhethekile kuzo zonke izinhloso ezingaba yililo lenkantolo noma ukuvulwa kwazo.

Ukulethwa phambili nokungenisa ukubamba

Isisindo se-Server HDD sikhokhisela ukulethwa okuphambili ngokushintshelana kwalo nelektronicsi. I-RPM ephambili yokugujula, i-15,000 RPM ikhomba ukufinyelela kudatha ngokushesha, ake imicuveliso yamanje amathulwa datha iyahlula ukubamba. Lezi zinhlayiya zikwazi ukufinyelela kudatha okuhlanganisa izivatho nezibophezo ezinkimbini, lokhu kuyindlela engcono lapho kusebenziswa amadatha amakhulu noma kudinga ukubamba okuthuluthuku. Ukusebenza kwe-Dynamic Fly Height ikantola ukuthakazelwa okungcono kwamagqabi, okwenza kube nemiphumela nezobukhona. Imicuveliso ye-firmware edvansile iyahlela ukuchonga ukuba amadatha ambalwa atholakale ngokucacile.

Ukuqonda Okuyinhloso

Izinto zokubambezelwa kwezinhla yezivivinyo zisungulwe ngokuhulumeniwe kuzindlela zokusebenza kwemiphakathi. Lezi zinhla zenquma izikhombisa ezingu- error detection ne-correction, ekhuselela ubumfihlakuse kwezethi lapho kusebenza ngokushesha. Isakhiwo samagetsi esibonakalayo senquma imoto enhanced nezinqawomthetho zokubeka i-head okuphepha ukuthi zilinde isebenza ngokuphepha. Iziphumo zokulandela ukuqala kuzo ukuvikela imehlo yesimo se-health ne-analysise yokubhekisekileyo ye-failure, okuvumela abasebenzisi base IT ukuthatha isenzo sokulinda ngaphambi. Imisebenzi yokuqinisekisa ne-yokuvala iyaziwa ukuthi lezi zinhla ziyafinyelela izimo zokubambezelwa zemiphakathi.

Ukugcinwa Kwenzeka Ngokuhlelwa Kwegogolo

Ispeedi yasekhweletu yasekweletu yekhweletu inikeza ukuphakama okuningi kwemisebenzi nokunciphisa izindleko. Ukuxhumiwa kwekhiye kaphakathi nokusebenza okubalulekile kukhuphela izindleko ngakhiye ngokulinganisa kuzindleko zokugcinwa ezifanayo. Ubude bokusebenza obuphakeme, okulinganiswa ngokuba kusebenza ngokuphelele ngeminyaka engaphansi, kunciphisa ubukhali bokubuyisa futhi kubukeke izindleko zokulungiswa. Iziphathi zokuncipha izindleko zokusebenzela kunciphisa izindleko zokulayisha ngaphandle kokungcola imisebenzi, kakhulu kunciphisa izindleko zokusebenza. Inkxenye enkulu yesikolethi yasekhweletu iyakunika amathuluzi amaningi ezindleko ngokulinganisa nezinye iindleko zokubuyisa futhi zokulungiswa.
