Izisombululo Zokugcinwa Kwedatha Efanayo Kwedatha Centers
Nedlulelwe ngokusebenza kwe-edatha, ubukhona bendawo yokugcina edatha kakhulu yindlela yedatha ephumelelayo. Server Izinga le-HDD lasebenza ngokubaluleka kakhulu ukuthuthwa kwezinye, ukuphumelela kwe-edatha, nokusebenza okuphakade. Ngenkikizo yedatha ehlukahluka fanye nezidingo eziphakathi kwezinhlelo zokusebenza, ukukhetha isisombululo semoto esemthetho sibe yindlela ebaluleke kakhulu noma yini.
Izikhishwa zedatha zihamba ngezwa yonke, zisebenzisa amathuluzi athathu kakhulu kanye nokwesha imisebenzi engapheliwe yezinkampani ezifuthiwe. Ukuqinisekile kwezinyathelo zedatha kuhlanganisa kakhulu nokusebenza kwezinhlelo, ukufinyelelwa kudatha, nokuholela kwezisebenzi. Izinga eziphambene nezinyathelo zedatha zibe nazo izitechnoloji ezithile fanye ukwesela ukuthi zifake amathuba athi aqedwa.
Izitechnoloji Zokugcina Zokwenyama
Izimpawu Zokuthembeka Eziphimile
Izinga eziphambene nezinyathelo zedatha zibe nazo izitechnoloji eziningi fanye ukwesela ukuthi datha ingatheni kanye nokudala. Lezi zitechnoloji kufaka phakathi ukuphela kwevibrations, izimathiko zokulungisa amaphoyinti, kanye nezinkomba zokusebenza ngokuthi zihlanjwe. Izinyathelo zidliwa ngokuphelele ukuqinisekisa ukuthi zisebenza ngokuphelele kumaqondo athi amaningi, ukuthi zingatheni ukuthi kuzozokhona ukusebenza ngokuphelele.
Ukulandela ubumnje, ukuphela kwezindleko, nokumelelo wezindleko zokugcina amandla kuzo zonke i-drives zokusebenza. Le teknolojiya ifanisa ukusebenza kubo ukuze kuthathelwe isiphazamiso sedatha futhi sikhugule isebenza ngokuphelele noma ngishumi elikhulu.
Imithombo Yokuthuthukisa Isikhathi
Izimali ezincane zokwenza izinto zikhuthaza ukuthuthukisa isebenza se-disk. Le zinto zilandela ukuphatha kahle kwe-caching, ukuthola okucacileyo datha, nokumelelo wezindleko zokugcina amandla. Lezinto zenza ukuthola datha ngokushesha futhi kuthuthukise ukusebenza, okudingekayo kumasevisi we-data center.
Ukuthinywa kwe-teknolojia yedisk enemelwe ngendlela yokusebenza kwe-Helium yabhayibhela isebenza se-HDD. Le teknolojia yekhalesi ukuthibele kahle kwezindleko futhi yenziwa disk ene amandla aphezulu nasezindleko zokuthembeka.
Ama-leader kumathketi nezinto zazo ezintsha
Izisolutions zase Seagate
I-Seagate isenza ngokuba yindlela encinyaniselwano kwi-HDD technology yoserver, inikeza inkqubo yobukhulu beqinisekiso lokusebenza. I-Exos series yabo inquma ngokuphelele kwezinhloko nezinhlelo zokuhlanjwa, okwenza yinto ephathelene kakhulu yezindawo zokugcinwa kwedatha. Ukuxhumana ne-HAMR (Heat-Assisted Magnetic Recording) technology kwenza umda wokugcinwa ngokwengeza kakhulu ukuhlanjwe kakhulu.
Ukugcina kwezimali nezindleko zokusebenza kwezikhala zabo kwenza amadivayisi aphumelela ngokukhulu ngaphandle kokwenza impact kumsuka. I-PowerBalance technology yabo isetshenziswa ukulayisha ukusetshenziswa kwamandla ngaphandle kokulahla kokuqina, kuxhomele kulo mlando obaluleke kakhulu yezindawo zokugcinwa kwedatha zamanje.
Imidwebo yeWestern Digital Data Center
Imisholo yaseMpumelelo yeWestern Digital ibonisa ukuphakama okuphezulu phakathi kwezixakiso nezindawo zokusebenza. I-Ultrastar series yabo isebenzisa imitekeli edlulelweyo felokhwe ngemikhawulo yeHelioSeal neOptiNAND ukulethwa kwezindlela zokugcina izinto nezixakiso eziphambene. Ukusebenzwa kwezinhlelo zokulayishwa ezinhle kumele kuthuthukisa ukusebenza okuphakade noma ngishelwe kuzindlela zokusebenza ezinhle.
Ukuthemba kweqembu kwenkululeko kubonakala kakhulu ngokuthi wadale imitekeli yokubhalwa ngokusebenzisa amandla nezinhlelo zokulungisa amaphoyinti amanqantela. Lezi zici zenza ukuba isikhathi eside sokusebenza kwekhathini kanye nokuthuthukwa kwezindlela zokubuyela izindleko ngabasebenziseli izinkampani zedatha.
Izindleko nezixakiso ezingathathelwe
Ukuthuthukwa kwezindleko zokugcina izinto
Ukuthuthukiswa kwezinhlobo zasekhaya zamadiski akhona kubangela ukuthuthukiswa kwezinhlobo zokugcina. Izinhlobo ezenzekelwe kuzona manje zinikeza amatholakaleli angaphezulu kwe-20TB, nezindlela ezithi kuzobekwa kwezinye ezizayo kuzo. Le siqinisekisa ukuthi amadatha kakhulu angagcina ngokungcono noma kube yimaliphi isikhundla esifanayo.
Ukusebenzisa izitechnolojhi zokubhalwa ngokuthuthukile zilungiselelwe ukuba yindlela yokufikelela kule meko. Abasebenzisa izitechnolojhi zokubhalwa ngokuthuthukile bahlala bainvista emareshini nasezimalweni ukuthuthukisa kakhulu ukugcina nokusebenza.
Ukulungiselela kwezisebenzo
Izinhlobo ezahlukene zasekhaya zamadiski zinikeza amadiski angokwezisebenzo ezinhlobo ezithile. Nakho ukungaba noma ukufinyelela ngokulandelana ngezinhlobo zedatha noma ukugcina ngokulandelana ngezinye izinto, ukukhetha izinto ezifanele kakhulu ziyindlela yokuthi isithemu sisebenze ngendlela engcono.
Ukuzwa imithwalo yokusebenza nokuthobela kuyakunceda ukukhetha iteknoloji yemvelo enemihla. Lokhu kufaka phakathi izidingo zokwenza IOPS, imithwalo yokufinyelela, nokudinga esikhundleni.
Imihla Emandla Nezinhlobo Zokuxhuma
Izinhlobo Zokugcina Ezintsha
Isithakazelo seHDD server sikhululekile ngokungena kwezitekni ezintsha. Ababhuyezi bavutha izindlela zokubhalwa ezingenelona, kanye neHAMR neMAMR, ukuze afinyelele kwezinkinga eziphezulu. Lezi ziboniso zayakuvumela amadivayi okudlula kwezinkinga eziphambene noma kuyadinga ukuthula.
Ukuthumela kwezinto ezilandelayo ngemfundo ye-AI lokuhlinzela phamtshelwe nokuthuthukisa imisebenzi yindlela enjalo yokuthuthukwa kwezindutye. Lezi zindlela zayakuthuthukisa ukuthula kwe-divayi nokwenza ngokulula ukuphathwa kwezindawo zedatha.
Imithwisto Yokuphila
Izinhloso zasevisi zase-HDD ziyakhulula ukuzithuthela kumvelo. Lokhu kufaka phakathi ukuthuthela kwezinhloso ezingcono kwezimali, ukusebenzisa izinhlobo zokubuyela futhi ukuncipisa impikiswano yemvelo yesimo sekuhlinzwa. Isifiso senhlalo ukuthuthela kuyathunyelana nezidingo eziphakathi kwezimboni zomvelo ezinhlangukileyo.
Lezi zinyathelo ziyakunceda kumvelo kodwa futhi ziyakunciphisa izindleko zokusebenzela futhi ziyakuntula imikorisano yenhlalo yezokuthuthela kwezimboni zokusevisela.
Imibuzo Evame Ukubuzwa
Yini indawo esembenyayo ye-HDD yamakhiwo?
Izinhloso zase-HDD zasevisi zinhloso zihlinzwe ngokuphelele kwezinyanga eziyedwa noma ngaphezulu kanye ne-Mean Time Between Failures (MTBF) engu-2.5 milione i-awhu noma ngaphezulu. Ngokusebenzela okunormali futhi noma kunemvume, lezi zinhloso zingakhipha inkululeko yasevisi kwezinyanga ezi-5-7.
Kunjani ukuhluhlana phakathi kwezinhloso zasevisi nezinhloso zomsebenzisi?
Izinhlobo zasevisi zokugcinwa kweHDD zidizayna izinhlobo zazo ngokwemfayela ngemibandela yokuthula, ukwelashwa okuhle kwevibrations, nokulinganisa okuphezulu kwezimo zokusebenza. Zafaka futhi imfayela yokusemelana nezinhlelo zokulungisa impendulo, ukhando olude olukhiye, futhi ukulingana okude kunezinhlobo zasevisi.
Yiziphi izinhlobo efunekayo ukuzwa xa ukukhetha izinhlobo zasevisi zokugcinwa kweHDD?
Izinhlobo eziphambene nazo kufana ukuzwa izimo zokusebenza, amathela aphethe amandla, izinhlelo zokusebenza, ukusetshenziswa komoya, nokutholwa kwezindleko ngokuphelele. Kuyafanele futhi ukuzwa ukuthula kwezinhlobo, izimiso zokukhona, nokutholwa kwezinkhambu ngemva kokuthenga xa ukukhetha izinhlobo zasevisi zokugcinwa kweHDD.
