Hardware wekhasi. Ukwazana lokuqala

Ochwepheshe abaningi emkhakheni IT uye wabhekana kaningi le nkulumo ezinjengokuthi "hardware wekhasi". Futhi Akukhona ukuthi kumane kuqondane, ngoba lapha kufanele abhekane njalo Ukwakha-up of imishini amandla. Kuyini wekhasi? Yini lokho? Yiziphi zako ezisemqoka nemibi? Ake sizame ukuthola.

Igama elithi "wekhasi" libhekisela inqubo nekwetfula iqoqo idatha ulwazi kahle ichazwe. Ngenxa yalokho, zikhona izinzuzo akutholakali kokuqala ukucushwa kwesistimu.

Ukuze bezibona sobala Kumele kuqashelwe ukuthi le nqubo uhlukaniswe ezimbili, enye yazo - ku wekhasi ezingeni uhlelo lokusebenza (uhlelo), kanti eyesibili - wekhasi hardware (iseva).

Kuze kube muva nje, i-software wekhasi bekulokhu ethandwa kakhudlwana, njengoba kuvumela ukuthola amakhambi ezobuchwepheshe. Nokho, kuleli qophelo ukwesekwa isikhathi wekhasi (hardware) is kakhulu anda, sisivumele shift ngokushesha esuka endaweni ehamba phambili esasisandulele. A indima juqu kukhala lapha ngokwenza ngcono ukusebenza ohlelweni futhi umthamo.

Hardware wekhasi. izinzuzo

1. Enough elula platform ukuthuthukiswa wekhasi (uma eqhathaniswa ukuthuthukiswa software wekhasi). Lokhu kukunika inzuzo ngokuphelele ngesikhathi ukudala amapulatifomu entsha futhi kunciphise nezindleko zabasebenzi.

2. kanyekanye futhi ezimele yokuqalisa pair of ezisekelweni virtual (ebe egcina kungenzeka ngokusebenzisa ngamunye ngamunye), ukuthi, ngokufanele, ukusebenza kohlelo.

3. I kungenzeka nokwenza.

4. lula ukuphathwa nengqalasizinda amaseva.

Hardware wekhasi. amaphutha

1. Izidingo High mayelana nehardware izixazululo (amaseva).

2. Izindleko High kwezinhlelo ubuchwepheshe.

Kunezinhlobo eziningana izinhlobo ezahlukene iseva wekhasi. Uhlobo lokuqala - kuyinto ukuhlanganiswa (elinengqondo okumnandi amaningi amaseva virtual kwi-server ngokomzimba olulodwa), uhlobo yesibili i-Ukubuthelela imishini ngokomzimba endaweni eyodwa (elinengqondo), ogama njongo - yokusingatha umsebenzi onzima.

practice inhlanganisela avunyelwe ezimbili zama. Ukuqalisa noma iyiphi yalezi zinhlobo kungenzeka kuphela uma hardware abafanele (CPU esekela hardware wekhasi ubuchwepheshe).

Kuleli qophelo ngesikhathi kukhona ezahlukeneyo ezivamile ubuchwepheshe ukwakhiwa ngokusekelwe AMD izilimi futhi Intel. Ukuze uthole ukuthi kahle hle ukuthi yiziphi processor onobuhle ukusekela iseva wekhasi, kufanele uye kuwebhusayithi nomkhiqizi futhi sibheke kudivayisi.

Ngokuvamile, i-hardware wekhasi - lena ubuchwepheshe ngempumelelo kakhulu futhi elula ukuthuthukisa umkhiqizo. Ukuze uqonde ukuthi bangaki abantu abayozuza yamandla ayo, kwanele ukusho ukuthi ubuchwepheshe elisetshenziswa izinhlelo zezimboni kanye amadivaysi ezokwelapha, ingasaphathwa izinkampani evamile esikhulu ne lwemikhumbi elikhulu kumadivayisi lobuchwepheshe, abafisa sichubeke nekuhlanganisa yabo izinsiza zokukhiqiza.
