isisithuthi se-server HDD esebenza ngama-7200 rpm

I-7200 rpm server hard disk drive iyisisekelo esibalulekile kuzindleko zokugcinwa kwamanje, ekunikeza ukuphelelwa okuphezulu kwezindawo eziphethekayo nezokutholwa kwezindleko ezinhlobo zokusebenza. Lapho sebenza ku-7,200 rotations per minute, le ndrive zinikeza izigaba zokufinyelela data ngokuvamile ake nazo zilinde isimo sokubulawa okudingekayo ukuze sizive nezinsizakwana. Le ndrive ngokuvumelekile zinezinzwa eziphezulu ze-cache, eziqukethwe phakathi kwe-64MB kanye ne-256MB, okungcono kakhulu kunikeza ukuguqula kwe-data futhi kube lula ukucima kwezikhathi eziningi zokufunda/nokubhitha. Idrive ezakhiwe ngemikhiqizo yezindleko zokusebenza ngokuningi, i-7200 rpm server HDD ezifaka phakathi izindleko zokulungisa amaphoyinti, ukulungiswa okungenhla kwe-vibration, nezobuchwepheshe olukhulu olwenziwe ukulinganisa ubumfihlakalo kuzindleko eziphiloselwe kakhulu. Le ndrive ngokuvumelekile zenikeza amaphesenti wezogcinwa eziqukethwe phakathi kwe-1TB kanye ne-16TB, lokhu kuyakunceda ukuthi kusetshenziselwe kuzindleko zokusebenza eziningi, kusukela kuzindleko zasekhaya kuya kuzindleko eziphezulu zodatengcele. Le ndrive usebenzisa izibonelo zokubhala ezikhulu njenge-CMR (Conventional Magnetic Recording) ukuze akunikeze isebenza esiphakeme nokuthuthukiswa kwezocingo. Ngaphezu kwalokho, zinezinto ezifana ne-hotp-plug capability, okuvumela ukuthi ikhutshwelwe ngaphandle kokushuta komthwadi, ne-RAID compatibility ukuthola ukupheliswa okuningi kwezocingo nokuthuthuka kwezosebenza.

I-HDDs zaseveri zokuxhumana ne-7200 rpm zinikeza izinkantolo eziningi ezingcono ukuthi zibe yinkqubo yokugcinwa kwezinhlelo zokusebenza. Okokuqala, zinikeza ukuphepha okunguqu phakathi kwekhuba nokhokho oluncedisayo, zanelisa amaspeezi wokufinyelela edatha ngendlela ethembekile futhi azikhombi izindleko ngaphansi kuka-SSD noma kwezinye i-HDDs ne-rpm enkulu. Le ndrive ingcono ekuphileni kwezimo zokusebenza, engasebenzisa okunye okwengeziwe kuhulumeni ngokushesha ngemikhiqizo yabo ye-cache futhi ne-firmware efanise. Ubukhulu bazo bokwenza ukuthi baleke kakhulu, nezinselelo zokuthi zingakiwe ngemva kokuthi zingakiwe (MTBF) ziqukela ngaphezulu kwe-1.5 milioni i-ilayezo. Ukusebenzisa amandla akhona kuyinto enkulu, ngoba le drive isebenza ngamandla ngaphansi kuka-zinye ehlukahlukene nazo ngelishesho futhi azikhombi ikhuba lokusebenza. Ispeedi sokuxhumana ne-7200 iphawula kakhulu ekufinyeleni/kwakhiweni kwezinyathelo eziphandeyo, lokhu kuyindlela yokuba le drive iyisiko sokwenza ubeko, ukugcinwa kwedatha, nokugcinwa komkhumbi wezimpahla. Futhi inikeza izinkqubo zokulungisa amaphoyinti nezinkinga ezinhle ezingakhonza ukuthi idatha ibe yimali noma kube yini. Le drive inkxowa nezinhlelo zokugcinwa kwezinhlelo zaseveri eziningi, ukuze kube nemveliso encane kwezinhlelo zaseveri eziphelelwe. Ubukhulu bazo bubonisa ukuphila okuningi ngokuvikelwa kwe-vibration futhi kwezinklinganiso zokulingana, ukuze kube yisiko kuzindawo zaseveri ezine dense. Ngokudla, le drive ngamaqina amaningi athola ukuvikelwa okuningi futhi nezinkqubo zokuvikela kwezinhlelo zaseveri, ukuze kube nenjongo yokuthi abasebenzisi babe nemithandazo yekhasimende. Ukuphela phakathi kwezokuphila, amandla, nokhokho oluncedisayo kuyindlela yokuthi i-HDDs zaseveri zokuxhumana ne-7200 rpm zibe yinkqubo yokutholwa yezinhlelo zokusebenza ezingcono ukuthi zilungise ukugcinwa kwedatha futhi azikhombi ukuthi izindleko zizonke ziyingcono.

Ukubuyelelwa kanye nokwenene kwezinhloso zasekhaya

I-HDDs zasevisi ezingaphansi kwe-7200 rpm yenzelwe ngokuthola amakhiyini obumnyama nomafozwa omuhle wokuqinisekisa ukubaluleka nokunakekile kakhulu emazingeni esekela kakhulu. Lezi disku zenza nezinhlelo zokulungisa iphutha ezifaniso ezilimelela kanye nokuqinisekisa ukugcinwa kwedatha, okwenza umrholo ophansi kakhulu wekulahlekelwa noma kukhinywa kwedatha. Isakhiwo solwandle silandelwe sikhona izinhlelo zomkhombi ezinezindleko zokuhlala kakhulu futhi zingahlali kuzindleko eziphezulu ngisho nangezinsizakalo eziphakeme, akeke namathuluzi amanzi osuku olukhulu. Iinkcukacha ezibalulekileyo zokuvikela iphambano enye yezindawo ziyadinga yokusebenza kwe-diski. Lezi disku ziphansi kwezivivinyo eziningi nezivavanyo ngokucophelela, okuyinto engaqiniseki ukuthi ziphumelela imivo yesikhathi eside. Ngemibono ye-MTBF efana ne-1.5 milione i-ilayithi, lezi disku zinikeza ukutholakala okudingekayo kuma-aplikeshini abusiness. Ukusebenzisa izinhlelo zokuvikela ngaphambi kokuba kufele iphutha kuvumela ukutholwa kolwazi lwamaphutha ahlinzekayo, okwenza ukungenwa ngokushesha futhi ukuthi kungenze intando lapho kungekho into.

Ukudizayna Okuthuthake Isisebenzi

Ukucwangcwa kwezinhloso zokusebenza zeHDD yamashini yoku-7200 rpm yadizainwe ngokuthuluka ukuthumela ukufinyelela idatha ngokuvumelana nezimo zomqakathi. Lezi zinhloso zenqubo ye-cache ezinkulu ezingena njengesihlahla phakathi kwamashini nekhazini lekugcinwa idatha, kakhulu ukuhlela ubunzima be-idatha nokunciphisa isikhathi kusukela kusibonakaliso okanye ukubhala. I-firmware iyagcinwe kuzindleko zaseMpesheni, ibhokisela ngokuhle izicelo eziningi ngasinye futhi ithathiselwe amaphethini okuqukethwe. Ispeidi yokuphendula yama-7200 rpm inikeza uhlelo olungilelo phakathi kwezikhathi zokufinyelela nezindleko zokusebenza, lokhu kwenza le zinhloso kungcono kuzindleko ezidinga ukuguqula idatha ngokulandelana. Izitechnolojhi eziphambene ne-queuing zokumema ikhanda ukwedlula uhlelo lwezisebenzi zidatha, ukwenza intungamayo kakhulu nokunciphisa ukushintshana okungeke kube khona. Le zinhloso nazo asikavumi imisebenzi yeRAID, ekunikeza amaphetho alandelayo kuzindleko nezinqumo zokuxhasa kuzinye izinhloso zomqakathi.

Imishenketi Yokugcinwa Efanayo

i-HDDs zasevisi zamanje amanye amaphrojekthi okusebenzela kakhulu ngokuthuthukiswa kwezimali ezikhangelayo. Le ndawo zinikeza ukhawunti oluningi, okungenhla kusuka ku-1TB isive ku-16TB, ukunika amakhiyani ukuthuthukisa umbhobho wazo ngendlela efanelekileyo. Le ndawo zenquma izimo zokuguqula ngokushesha, zinikeza ukuthuthukiswa okuphephile kancane futhi kungena amathimekile. Izinhlobo nezindlela zokuxhumana nazo zenquma ukuthi zilayihlale kangcono nenkampani yezimali eziphezulu, lokhu kuyakuvumela ukuthi usebenyiswe kuzinye izimali nezibophezelo. Le ndawo zenquma izinto ezijwayelekileyo zokuphatha izakhiwo, njengokuthiwa phakathi nezakhiwo ezifanayo, zinikeza ubukhona bezindlela yokuphatha izindleko. Izinga lezimali elingeni lemvelo lizo yakuvumela ukuthi usebenyiswe kuzindleko eziningi, futhi izindlela zazo zokuphatha ukushisa zinikeza ukusebenza okuphephile emasimweni amaningi. Ukuxunyaniswa kwemali enkulu nezimali ezikhangelayo kuyakuvumela ukuthi le ndawo zenzeke ukulayisha izindleko, lapho kungena njengo-mali engenziwa ngokuthembekileyo futhi kuyakuvumela ukusebenza okuphephileyo kuzinye izinto.
