i-10k rpm server hdd

I-10K RPM server hard drive ikhona lelimali esikhundleni somkhiqizo we-enterprise, onikeza imiphumela emikhulu kanye nezinhlanhla zokusebenza kakhulu kuzindlela zokusebenza zezinhlanhla. Zisebenzisa ku-10,000 rotations per minute, le ndrives zenza uhlelo olungilelo phakathi kwezindlela ezilandelako zokufinyelela kwe-SSDs kanye nezinsekelelo eziphakeme zezindlela eziyisisekelo. Le nqamleza yokuvula kwezindlela ifinyelela kudatha kakhulu, ngemibala yedatha enkulu ngemibala engu-3 milliseconds, lokhu kuyindlela engcono kwezokwenza izicelo ezininzi kanye nezinhlanhla. Le ndrives zenziwe ngemikhiqizo yesikhundla se-enterprise, inemathivhamu engenhla efenkula imisebenzi yokufaka kanye nokususa kudatha kanye nokuphila kwayo. Zingaba nezinkumbulo eziphezulu, ngamathuba aphezulu kuno-256MB, okuhle kakhulu kubangelisa ukwazi ukubamba izicelo eziningi ngokuvamile. Le 10K RPM drives inemisebenzi yokulungisa amaphoyinti amakhulu kanye nezinhlelo zokulandela kudatha ngemisebenzi ye-S.M.A.R.T., onikeza imininingwane yekhwalithi yedatha ngokuvamile. Ukuhlanganiswa kwabo kuyinhloko inkulu nezinhlelo zokulondoloza kwezindlela zokuvula, okunikeza ukusebenza okuphakeme kuzindlela zokusebenza ezikhundleni. Le ndrives kuyindlela engcono kwezokwenza izisekelo ezingcono kudinga ukusebenza okuphakeme kanye nezinhlanhla zokugcinwa kudatha, lokhu kuyindlela engcono kuzikhundla zokugcinwa kwezinhlanhla, izinhlelo zokusebenza zase-cloud, kanye nezinhlelo zokusebenza ezikhundleni.

Imidrifi yesikhombisi ye-10K RPM ibonisa amanye amaphesenti atsha okuthiwa yinto yokukhetha ngokweqile kuzindleko zokugcinwa kwamanje. Okokuqala, izinikeza ukusebenza okuphezulu kunoma imidrifi e-7,200 RPM, ekunikeza izigaba zokufinyelela kudatha ngokushesha nezinselelo eziningi zokuhambisa, okuyindlela esenza ngayo kuzindleko zokusebenza kudinga ukuphendula ngokushesha. Le ndrifi ziyahlakanipha emasimweni wokusebenza okuvumelana, engenzi kahle ukubophelela noma ukufinyelela kudatha ngendlela engenabangela noma ngendlela ethulwane. Ngokulinganisa nokhaliphi, le ndrifi zenkumbela indawo ephakathi phakathi kwe-SSD ezinzima fanta ne-HDD ezinkulungelo, ekunikeza ubuningi obungcono phakathi kwezimali nezisebenzi ezisenza ngazo ukuba yinto engeke ithinte kuzindleko zokukhula. Ukuhlolwa kwabo okungu-grade yentloko kunezinhlelo ezifortele ukuthola kakhulu, akukhojwayele ukuphumula kwezimali nezinselelo ezinhle zokushintshela amaphoyinti, okwenza ukuba abilite baphezulu kanye nobude obude phakathi kwezikhweba (MTBF). Ukunakekela kwezimali yindlela elandelwayo, njengoba le ndrifi ngamanye amaxesha ikhishwa ngokuncane kwezimali kunaleli ezinezulu e-15K RPM kodwa inikeza ukusebenza okuphezulu. Ukuhlolwa okuphezulu kanye nokuthuthukiswa okuphezulu kwezinfurmwa kungenxa yokunikeza ukusebenza okuphezulu noma xa kusebenzelwa ngokugcwele, okwenza yinto enkulu kuzindleko zokusebenza ngokweqile nezinhlelo zedatha. Ngokwengeziweyo, ukuthi uyavumelana nezinselelo zokugcinwa kwamanje nezezimali kungenxa yokwenza ukuthi kube lula ukulayisha ku-infrastucture esivele ikhona, okwenza ukuba kuncane izindleko kanye nokucingatha.

Imidrifi yesikhombisi ye-10K RPM yenziwe ngemikhiqizo nezinhlelo zokuhlanganisa ezinikeza ukusebenza okuphakade nokulondoloza kakhulu kumaphindwa amakhishini. Le ndrifi zinezinhlelo ezingaphezu kwesibonelo sokuhlolwa nokulungisa iziphoso, ekuvikelwa intshisekelo yedatha lapho kubalulekile ukufunda nokubhala. Isakhiwo somkhumbi sijwayelekile sinezinhlelo zokuvikela izimpukane ezinhle zomotola nezicathami ezidingekile ukwenza ukunciphisa izivikelelo, noma lapho kuzimelwe kakhulu. Imigudu emijwayelekile yokushintsha yefirmware iyahlola futhi ikhombisa imisebenzi yesikhombisi, iyashintshe izisindo ngokushesha ukuze ithinte isebenza esiyane. Le ndrifi nezinhlelo zokuvikela impumelelo yokulahla amandla aphathiwe ukungena edatheni lapho kungeke kube nemvume, ukunikeza ukuthi idatha ebalulekile iyakuhlala iphephile. Ubunzwa bawo bubhekene nezinto ezinhloso elithile zokusebenza ezisetshenziswa kumasevisi aphindwa amakhishini asemathini, lapho kungenxa yezimo zokusebenza nezimpukane kungaba kukhona isixhobo esikhulu.

Ukusebenza okuhlelwe ngokuphephile kwezindawo zokusebenzisa amaphoyili

Le ndawo zokugcina amaphoyili zinhlelwe ngokuphephile kwezindawo zokusebenzisa amaphoyili, nezifunda ezinhle zokuxazulula izinkomba fakwe ngemibono ye-Sophisticated caching algorithms and command queuing capabilities esenza ukusebenza ngokuphephile kuzindawo zokusebenzisa abasebenzisi abaningi. Isantya se-RPM se-10,000 spindle speed siza kufinyelela ngokushesha kudatha, ngenkathi yindlela enye edala ukunciphisa isikhathi ekudinga sokwenzelwa kwezindawo zokugcina amaphoyili. I-Cache buffers eziphakamile, ngokuvumelana no-256MB noma ngaphezulu, siza ukugcina ukusebenza ngokuphephile ngokuthi kubekwe kudatha ohlangene nawo khona fikizwe ukuxazulula imithwalo yokufaka nokususa. Le ndawo zokugcina amaphoyili zenziwe ngemibono engenhle yesoftware esenza amagama okwenza nokuhlukanisa izinkomba ukuze kuncipise ukuguqula kwebhedi fikizwe ukuba kube phephile ukusebenza. Lokhu kungenxa yokuhlelwa kungcono kakhulu kuzindlela zokusebenzisa i-database, izindawo zokusebenzisa i-virtual, noma izinto eziningi ezingenxa yokuthi kudinga ukugcinwa kwezinto ngendlela ethandwayo fikizwe ukusebenza ngokuphephile.

Isisombululo esineyimali elincane kwezindawo zokugcina amaphoyili

izidrivu zokugcinwa zasekela ze-10K RPM zibonisa indlela yokugcinwa engcono ngemali kuzindlela zokusebenza kwamakhaya, zineqondo elungile phakathi kwezinto eziphumelelayo, amandla okugcina nokhawula ngokwelinye le-Gigabyte. Lezi zidrivu zinikeza izinto ezinhloso yeklasi yesekela nezintobeko eziphumelelayo kancane kuphela yemali esebenziswa kuzo izidrivu ezingapheliwe (solid-state), lokhu kuyindlela enemali encane ukusebenzisa kuzo ukugcinwa kwamanani amakhulu. Iindleko zazo zokudla komoya ngaphantsi kokudla kwe-15K RPM zidrivu kubangela ubuncinciso bendleko yemisebenzi ngemva kwesikhathi, futhi besebenza ngendlela engcono yokusebenza kuzo zokwenza iziasiphamandla eziphumelelayo. Ubude bokusebenza kubo nobungovuno obuphumelelayo bazo bengcina amadlivu alindelwe futhi abambe indleko yokubuya futhi abambe isikhathi esingakanani sokulala kwesistimu, lokhu kubangela ubuncinciso bendleko yokuqeda konke. Ukutholakala kubo nokwengeza kuzo izinhlanganisela zasekela zokugcinwa zezinhlangano eziphelele kuzo zenza kube lula ukufaka phakathi kwabo kuzo zokusebenza ngaphandle kokudinga izindlekephelo noma izilungiselelo.
