Izinqumo Zeqiniso Lephakeme Ezingenziwa Ngazo Imiphakathi Yasekuhlaleni
Kumzabalazo wobusiness olusemandleni kuleliyanga, ukukhetha i- server hard drive kuyisisekelo ekubeni kube yimali imisebenzi nokuphulwa kwedatha. Izinqumo zokugcina kwe-enterprise zaziguguza kakhulu, zinikela izinkampani eziphakade izici ezibalulekile ezigcinwe ngaphambili kumakhono amakhulu. Ukuziqonda izinto ezibalulekile zomgcini wohard drive weserver kungasiza izigaba ukwenza izinyathelo ezifanele ezingqondene nempilo yawo nokuthembekile kwegunya.
Izentityebi zamanje zakhela nokusebenzisa izinhlwembu ezikhulu ze-data ngalinye nalinye, kepha ukugcina kwe-infrastucture esebenzayo kubalulekile. I-hard drive yomqondo engakhethiwe kahle ichaza ukutholakala kwe-data futhi kuyilapho okunye okukhathazekile kwi-performance yesistimu, ubumnandi, ne-izindleko eziphelele zokulondoloza. Leli guida elijwayelekile libonakala kizindlela ezibalulekile ekukhetheni izisombululo zokugcina zenhla yezendalo ezikwamukelwa umsebenzi wakho omncane.
Ukuziqonda Kwe-Inhla Server Izinkoloko Zokugcina
Izinhlobo Zesandiso Se-Hard Drive Nenkokhelo
Isandiso se-server hard drive sinesimiso esikhulu ekubekeni iinkokhelo yalo. Izisombululo zamanje zokugcina zenhla zisebenzisa kakhulu i-SAS (Serial Attached SCSI) ne-SATA (Serial ATA). I-SAS drives zanelwa ngokuvamile nge-performansi enempela kanye nobumnandi, ngakho ke zihambisana kakhulu nezindlela ezine-engcinga inkohlako. Lezi zivala zabelana nokuthuthana kwe-data ngokushesha kunezinye i-SATA.
Nakuba izikrini ze-SATA zingasebenze ngemipumela engaphansi, zihlala yisikhetho esinengilima kakhulu kubamakhaya amadala anobuchwepheshe obuncane. Kudingeka ukuthi isikhetho phakathi kweSAS neSATA sibaluleke ngokuthi yiziphi iziphakasho zakho ezithile kanye nempumalanga yomoney. Amathambo amaningi ayisetha indlela ephathelene nokusebenzisa izibonelo ezimbili ukuze abalise izinselelo kanye nemali.
Ukuzimisela Kwesigaba Nezimali
Xa usetha ikhardi yeserver, kumele ukuzimisela kwesigaba kubalulwe akukade kubaluleke kubuchwepheshe bamanje kodwa futhi ubuthuthuki besifuthe. Izikrini zezinhlangano manje zinikeza izigaba eziquka kusukela kuzingu terabytes ezimbalwa kuze kube ngu-18TB noma kangakanani. Okumcwaninga kukuthola indawo efanele phakathi kwegigaba, ukusebenza, kanye nempumelelo yomoney kulocandelo lwakho okhethiwe.
Ukuthuthukisa kuyakha kakhulu njengoba izinkampani ziyakhula. Inkokheli yasekhondlela engathembekile kufanele ikhulule imiphumela ngendlela elula ngaphandle kokudinga ukubuyekezwa kwesimo esigcweleyo. Cinga amadivayi angolidekelwa emathontweni akhona kanye angavikeli i-RAID eziphumelelayo ukuze kugcinwe imininingwane ngempawu.
Izikhala Zokusebenza Nezici Zokuthembeka
Isivinini Nokwabiwa Kwemali
Ukusebenza kwedivayi yeserver kithathwa ngokulinganisa izikhala ezahlukene, kanye nesivinini, isikhathi sokufinyelela ngokungahleli, nokulinganisa okuphelele kohlelo lokuthintela imininingwane. Izidivayi ezinezizwe zokuphila zihamba ngokuvamile ngama-7200 RPM noma ama-10,000 RPM, zinikeza IOPS (Imisebenzi Yokungenisa/Ukuthola Ngemizuzwana) enzima kunazo edolobheni. Lokhu kukhona okubalulekile kumsebenzi ofuna ukufinyelela kwaye ukusebenzisa imininingwane ngokushesha.
Izilinganiso zokufunda kanye nokubhala ngokulandelana zibalulekile kakhulu kubusiness ezihandlenza iifayili ezinkulu okanye ezirhulapha imisebenzi yedatha. Iindleko zokuthumela ezigcweleyo zezikhombisi ze-server zinokufika kwi-megabytes ezinhlanu kwaye ziphelela ngemizuzwana, ziyathembisa ukusebenza kahle kwezisebenzi ezibalulekileyo ze-business.
Ubunzima kanye Ngesikhathi Esidingekayo Phakathi Kweengxaki
Iindleko ze-server zezinhlangano zibekwe ukuba zilindele ukusebenza ngokugcweleyo emazingeni apholileyo. Ababhengezeli babenza le ndleko ngezinto ezibanzi eziphucukileyo, kubandakanywa ukulindelana okunempelweni, ukusabela kahle kwesithelo, kwaye inzuzo yokulungisa ngxaki. Isilinganiso seSikhathi Esidingekayo Phakathi Kweengxaki (MTBF) yendleko yesingqiselo sikhuphela ngaphezulu kweyure ezili-1.5 million, esikhulu kunezinye izakhelo ezisetyenziswa yi-consumer.
Izici ezidebezelayo zomlando wokusebenza kunciphisa ubumfihlo bwebhulosi futhi ukuvikela ukungahlelwa kwizinsuku zokuphazanyiswa okanye izinkinga zesistimu. Lezi zivinini zafaka futhi izici zokuhlengahlenga okungaphendula abagcwalisi besistimu ngamathuba athile ngaphambi koko akwazi ukuphazanya ubumfihlo noma ukuvalwa.
Ukulungiselela Kwezimali Nokuzimisela Kwemvume Yembali
Umyalezo Wesilinganiso Sokuqala Sokuthatha
Nakuba igcino lokuqeqeshwa kwezinhlinzeko zohlelo lwesivinini kungaba phansi kwegcino lezinhlinzeko ezisetyenziswa yisiphequluli, ikhanda eliphelele lokusebenzisa lingaba libonakala lithandwayo ngokudala. Izindlela ezibangela ukufa njalo kubalulekile kungaba kukhondo olude olukhulu, ububi bempilo, nokuncitshiselwa kwizidingo zokuhlengahlenga. Kumele amakhaya aphatheke lezi zinto uma bekwa kuyabuyekeza imfuno yabo yesilavu.
Ukusebenza kwezimali kuthatha indima ebalulekile kakhulu ekugcineni izindleko. Izidiski zokugcina ze-sever zamanje zihlanganisa izici zokulahla amanzi wezimali azikwazi ukunciphisa kakhulu umsebenzi wamathili ngaphandle kokuchaza isebenza. Lokhu kuyakwenzeka kakhulu kubalulekile emazingeni ezenziwa yizimali apho izindleko zezimali nezindleko zokulahla kuyizindleko ezikhulu zokusebenza.
Ukuzithenjela Kusindiswa Kwemisebenzi Yomnotho
I-HDD esemthethweni ingakwazi ukuqhamuka kakhulu emsebenzini nasekuhlanzeni kwemisebenzi. Izikhathi ezinkulunkulu zokufinyelela nezindlela ezinobukhona obungaphezu ziyafana nezikhathi ezinkulunkulu zokuphendula kohlelo olunye nokuhlanzana okunembala, okungakwazi ukuqhamuka kumsebenzi futhi ukuthembeka okunembala kumsebenzisi, okuqukethe ngqo emva yokuphuma.
Mqondela izindlela zokwenza kakhulu uma ukhetha izinqamlezo zokugcina. Izidrivu ezinezimo eziphambili nezobulungiswa okunembile zingasiza ekukhuliseni iziphazamiso kwimisebenzi yombuso, futhi zibe yizimali ezenzekelayo ngaphandle kokuthinta kakhulu kusendulo.
Izinhawu Ezilungileyo Zokusebenzisa Nezoloko
Izinqumo Zokusebenzisa Nezokuhlela
Ukusebenzisa kahle kwezidrivu zomnqweto kudinga ukuplanjwa nokusebenziswa okuncane. Qala ngokuhlola ngokucophelela izidingo zakho zokugcina nokwakheka kwezinto. Mqondela izinto ezifana nokuhlelo kwebizo, izinhlobo zezikhalo, nezidingo zemfundo xa usenza umphakathi wakho wokugcina. Sebenzisa izimakhiwo efanayo zeRAID ukuze uhlangane imfundo, amandla, nezidingo zokuphatha amathuba.
Ukudokolisa izibonakaliso zokufaka kuseto kanye nezimiso zokumiswa kubaluleke kakhulu ekugcineni ubunzima bokusebenza kwesistimu nokunceda ukuvuselela emva. Dala izimiso eziphumelelayo yokuqala izilondolozi, uhlaziywa lwesofthiweya, nokukhangelwa kokusebenza ukuqinisekisa ukusebenza okuhle kweqhikithi lakho lokugcina idatha.
Izimiso Zokukhangela Nokulungisa
Ukukhangela okuhlanjwayo kwezilondolozi zeseva nokusebenza kubaluleke kakhulu ekukhomeni idatha nasekugcineni isikhathi esingavuselekile. Sebenzisa izisombululo ezinhambiliyo zokukhangela ezingathola imithwalo ebalulekile njengezinkelingo, izilinganiso zemposiso, nokuthinta kwesifo. Dala izaziso ezihlomene ngokuzenzekalela kizinkinga mozwa futhi qinisekisa izimiso eziphumelelayo zokuxhumana nezimpawu zokuphepha ngaphambi kokuba ziyenze izinkinga eziningi.
Vula kanye ngcinezela izikwelelo zokulungiselela okuchazwe kangcono ezenzulwini, ukuhlinzekwa kwefirmware, nokulungiselela kwezikhathi ezithile. Cabanga ngokusebenzisa izindlela zokulungiselela ngaphambi kokuthi kuhlangene ngamathulwa amakhubalo ukuthola izinkinga ezinokuthi zihlale ekususweni kwayo.
Imibuzo Evame Ukubuzwa
Izidrivi zomkhiqizo zezinhlangano zilandela ngeke ziphele njani?
Izidrivi zomkhiqizo zezinhlangano zibalwe ukuze zisebenze kabhethepha futhi zalandela izonyaka ezi-5-7 ngemiphumela engcono. Kodwa, umkhawulo wokuphila kuyinto eyahlukene ngokushintshana kwesimo sezimali, imfundo yendawo, nezindlela zokulungiswa. Ukubheka kahle kanye nokulandela izimpendulo zomphathi ungakusiza ukwenza izidrivi zibe namandla.
Yini eyahlukana phakathi kwezidrivi zezinhlangano nezidrivi zezimali?
Amadivayisi e-enterprise anobuthakathaka obunikelwe kakhulu, ukwethembeka okungcono ekuvikeleni, ukuhleleka kwezimposiso ngempumelelo, nezibhedele ezide kunazo ezitholakala kuzo zonke izinhlayiya. Zidizainiwa ukuze zenze imisebenzi ngaphandle kwesikhathi futhi zazinzima kakhulu, ngokushesha kakhulu, ngaphandle kokuthinta izindleko. Lezi zinhlayiya nazo i-firmware esisodwa esihlelekile kakhulu emisebenzini yaserver.
Kufanele imicimbi iphule impahla ku-SSD noma ku-HDD yaserver?
Ukukhetha phakathi kwe-SSD no-HDD yaserver kubalulekile kumkonco wempiyoli yesifundo. Ngenkathi i-SSDs zinikeza imiphumela nezobuchwepheshe ngempumelelo, zenza izindleko ezide ngagigabhati. Amakhulu amaningi akhetha indlela eyinhambili, sebenzisa i-SSDs kumsebenzi omuhle futhi i-HDDs kugcine amabhanga, ukufinyelela kumpikiswano womphumela nokwenza izindleko.
