Ukucabanga Server HDD: Indlela YoKukhetha Imoto Eiyokusebenza

Imvume Yasekela Yemilayezo Yemfundo Yezokusebenza Kwasekela

Kunesembenzi yamadatyha, ukukhetha i-server I-HDD yindlela ebalulekileyo ukuze ikhumeke isebenza nezokuthembekela kwiindawo zasekela. Le zilayezo ezithunyelweyo zisebenza njengokona lwasekela datha nezemfundo zasekela zilandelayo, okwenza ukukhethwa kwazo ngumkelo omkhulu kwiiprofeshonal nezokupaka izicelo zasekela.

Server I-HDD zihlukana ngokubangelwa kwezinhlayiya zokusebenzisa, zinikeza ukuphila okuningi, ukusebenza okungcono, nezinhloso ezinhle zokuvikela 24/7. Ukuzwa lezi hlukelelo futhi ukwazi ukuthi kanjani ukukhetha ikhawunti enempilo kungase kube yimali engiyawo kwezinhlelo yakho nokuphepha kwezethi.

Izicaba Ezinhle nezinhloso zokusebenza kwezinhlayiya zezinhlayiya

Ukudizayina Wezinyathelo Ezinhle

I-HDD architecture ye-server inikeza izicaba zokuvikela ezinhle zokusebenzisa okuphambene nezinhlayiya eziyisicaba. Lezi zicaba zifaka phakathi i-motor shafts enenhle, imimandla yokubeka enenhle, nezinhloso ezinhle zokusebenzisa okuvikeliwe ngokuphelele. Ubunzima bokwenza okuphambene nezinhlayiya bunciphisa ukuvusha xa kusebenza, okunikeza ukusebenza okuphambene nekuphila okude.

I-HDDs zamaseva amanje nasebenza nezinhlelo ephambene yokufaka amagqabi aphumelele ukulungiselela idatha nokufinyelela kusikhashana. Lezi ziphumo zenza ukusebenza kubangelwa ngokuvumelana, ngakumbi kuzindlela eziningi zokugcina apho ukuvusha kungaba yinkinga enkulu.

Izinhlelo Zokusebenza Zokwelashwa Kwamagqaleli

Izokwelashwa kwi-HDDs zamaseva inezinhlelo zokulungiselela amaphoyinti, ukuphatha amandla nokulungiselela ukusebenza. Lezi zinhlelo ngamaqondo amathathu okulungiselela amaphoyinti anokuthola futhi athinte izinkinga ezingenzeka kabefore bayele idatha.

Ngokudonsela, izokwelashwa zamagqaleli zenze amasontiletho kanye nezinhlelo zokulungiselela ukusebenza, okungenzela ukuthi ukusebenza kube ngokuvumelana naphandle kokuthi kunezinga eliphezulu. Lezi ziphumo zibaluleke kakhulu ukuthi idatha ibe yinto evelayo futhi isistimu sibe yimali kuzindlela eziphambene.

Izinhlobo Zokusebenza Nezibonelo

Izinkinga Zokushisa Nokugcina

Xa kufaneka ukulinganisa imiraro ye-HDD yomsebenzisi, kukhona amathemu amaningi okufanele aqondwe. Umoya wokubhola, okungenani kwi-7,200 ku-15,000 RPM, uyadinga kakhulu ukufinyelela kwezinye nokuguqula izigaba. Amadivayisi akhulu akhona ngokuvamile amathemu amahle kodwa angaba yindlela enkulu yokuthatha amandla futhi engenera ukushisa okhulu.

Usayizi we-cache wasebenza futhi injongo ebalulekile kumiraro we-HDD yomsebenzisi. Amadivayisi we-enterprise ngokuvamile ne-cache ephakeme, ngokungafani kwe-256MB, okusiza ukuvikela imiraro yokufinyelela kwezinye futhi kuthuthukise inkimbinkimbi ye-system yonke.

Imiraro Yokuqiniseka futhi Yokuqaphela

Amadivayisi we-HDD yomsebenzisi ayadwa ukuthulela ukqiniseka okuphakade, noma kuthiwa ngokuthi (MTBF) okungenani kwe-1.5 miliyoni i-intamende. Le ndivayisi zihlola ngokuphelele futhi zihlola ngokuphelele ukuthi ziyakwazi ukwenza imisebenzi yezinhawu zomsebenzisi.

Izilinganiso zokusebenza, okukhathwa ngama-terabytes enkripthwe ngonyaka, zinikeza uboniso oluhle olwemvelo yedrivi. I-HDDs zezinhloso zokusebenza kakhulu zilandela izilinganiso eziphezulu kakhulu zokusebenza ngokusho kuzo zedrivi zedeshibhodi, lokhu kwenza kube yisiphiwo sezingxenye ezinhlelweni kanye ne-sebenzo esivamile.

Ukulungisa Amathuluzi kanye Nezinketho Zokuhlela

Izidingo ephakathi kweqembu lokugcina

Ukukhetha ukulinganisa kwe-HDD yedrivi okufanele kudinga ukuvuselela okujwayelekile kanye nokulandela ukudinga okuzokuthiwa kuzo. Idrivi ezinhloso zokusebenza kakhulu zinikeza amathuluzi aphakathi kwezifewu kuma-terabytes kuya kuma-20TB noma ngaphezulu. Kodwa, amathuluzi amakhulu awu yinto ebonileyo - izinto ezifanako nezindlela zokubeka, izidingo zokubuyisela, kanye nezidingo zokusebenza kufanele zenze isidingo kwezidingo zokulinganisa.

Umkhetho phakathi kwezinhlobo eziningi ezincane noma ezifewu ezikhulu kungaholela kwezifaniso nezinhlobo ezikhulu. Idrivi ezincane kuzo ezinhlobo zase-Raid kungaholela kwezifaniso nezinhlobo zokubuyisela, ake idrivi ezikhulu ingasebenze ngokulula kweqembu kanye ingase ngokunciphisa ukuthola kwezimali.

Imithwakelo ye-RAID

Izinhawu zaseva zinhawu zaseva kahle zisebenza kumqamatha we-RAID, kudinga ukuthi kucatshangelwe ngokucophelela izimo zokusebenza nezinhlanhla. Izinhla ze-RAID ezahlukene zinezidingo ezahlukene kwezinhawu zokubhala nezimali, ezithinta ukuthula nokusebenza.

Xa kusebenzisa izinhawu ze-RAID, kubaluleke ukusebenzisa izinhawu ezengezela ukulingana nezimo, bese kungenjalo kusuka kwenye indawo neyenye inca. Le ndlela ikunciphisa ukusebenza okulinganayo nokunciphisa ukwenza amaphutha nezinyathelo zokulungisa.

Ukuphepha nokuthuthukisa izindlela zokusebenza ngokwempiyela

Ukugcina ukuvikeleka nokuphepha okungaphakathi

Ukuvikeleka okudlule ukuvikeleka kwezinhawu zaseva kubaluleke kakhulu ukungahlinzeka kwedatha nokugcina ukusebenza okuphezulu. Ukusebenzisa izicathami zokuvikeleka kwe-S.M.A.R.T. zingakunceda ukutholwa kwezinkinga ezingenzeka bese kungena kwehlatshwa kwehawu.

Ukuqala isikhiwu sokuphepha ngokuzenzekelayo, okufaka phakathi ukufanekisa imiphumela nokuqasha kwezinkomba, kusiza ukuthi kube yimali kakhulu. Lokhu kufanele kube nekulwa kwezibuko, izindleko zokuvula, nezinye izinto zokuzimelela ezingakumbi imikhawulo yokusebenza ngemva kwesikhathi eside.

Imithwethwe Yokuhlela Imiphumela

Ukuhlelwa kwezinhlobo zokugcina imiphumela kufanele kube nekulwa kwezinkuntula zokuhlelwa nezinhlobo zokusebenza. Ukulayisha kahle kwezifanekiso, ukwenza futhi kwezinhlobo (lapho kudingeka), nekuhlelwa kwezinhlobo zezifayela kungaholela kakhulu kumaphesenti wokusebenza kwezinhlobo ngakumpela.

Ukusebenzisa imithwethwe yokugcina kanye nekulwa ngokucacile kwezithwelelo sokusebenza kungasiza ukuthi kube yimali kakhulu yezinhlobo zokugcina lapho kugcina amathimele nokuqeda ukusebenza ngemva kwesikhathi.

Imihla Emandla Nezinhlobo Zokuxhuma

Izinhlobo Zokugcina Ezintsha

Isimo se-HDD server sikhuluma ngokuthi kuhlelwa ngokuvuthwa kwezinhlelo yokubhalwa nokhuthula okuphansi. I-HAMR (Heat-assisted magnetic recording) ne-MAMR (microwave-assisted magnetic recording) zinhlelo zokubhalwa eziyizophesha ukhuthula okuphansi ngokushesha.

Ukuthiwe kwezinhlelo yokulawula ukulungiswa okuthuthukisiwe nge-AI nokulungiswa okuphimile kwezinhlelo zokulungisa amaphoyinti kuyisikhululo esibangelwa emuva, kungenzeka ukuguqula indlela ethiwa ngayo ukuphepha nokuthula okuphansi.

Umvutho Wokuvuthwa Nezinhlelo

Imisebenzi yokuvumelana nezinhlelo zokuxhumana phakathi kwezinhlelo zokuthiwa yizinhlelo zokuvuthwa kwezinhlelo zokuthiwa kwe-server. I-interface ezintsha nezinhlelo zokuxhumana zivulwa ukwenza ngokungcono ukuphanti amathuluzi amakhulu kanye nezidingo zokusebenza.

Izidingo zokuhlanjelwa kwemidla ziyakhiqiza izinhlelo, ngabe amathengi ayithinta ukusebenza kwezindleko kanye nezinhlelo ezisodwa kwezinhlelo zokuthiwa kwe-server kubucayi nokubhola.

Imibuzo Evame Ukubuzwa

Yini okwenza i-server HDD ngasemnye kwezinhlelo zokuthiwa eziphelele?

Izinhdd zaseva yenziwe ngokuthiwa yezinhlobo zokusebenza kwezinkampani, izifiso eziphambene nezinhlobo eziphakeme kakhulu. Zenziwe ukusebenza ngokuphelele kwezinyanga, zinikeza ukuvumelana okuningi kakhulu nezinhlobo ezinhle kakhulu kuma-warranty nezinhlobo ezinhle kakhulu kuma-workload kungezinhdd zedesktop.

Yini indlela efanele izinhdd zaseva ziye zilale?

Izinhdd zaseva zenziwe ukuthi zilale kusuku 3-5 ngemva kokuqala kokuqala, nezinhlobo zokuthiwa zingaphezulu kwe-1.5 milione i-isikhathi. Kodwa, ukuphila kwazo kungaphathwa ngokuthiwa kuhlanganisa nokusebenzisa, imithwako yemfuko, nezinhlobo zokuhlinzeka.

Ngaba kufanele ngihlanganise izinhlobo ezahlukene zezinhdd zaseva kwi-RAID array?

Kungenzeka ukuthi kufanele ukusebenzisa izinhlobo ezahlukene noma izinkampani ezahlukene kwi-RAID arrays. Ukusebenzisa izinhdd eziyidele kuzenza ukuthi iziphumo zibe yidele, zilungise ukuthi kuhlelwe kwezinkinga, kanye nokuthi kwehlise uhlobo lokuhlangana noma ukuthi kwehlise uhlobo lokusebenza.

Yini lekapasiti yezinhdd zaseva engiyokuthola kusistimu yami?

Ukukhona kwezinhawu kubangelwa yimfuneko yakho ngokuthile, kube ngaphakathi kwezimali eziphilayo, izindlela zokuthutha, izakhiwo zokubamba kabusha, nezinhawu zokusebenza. Cabangela amathiphu jikelela ukuhlelwa kweRAID, izidingo zokubonakala, nokuphakama kwemali xa ungena kulunye ukuqenjela.
