Ukuhlukaniswa kweseva chassis
Lapho sibhekisela kwicala leseva, sivame ukukhuluma ngecala le-server leseva le-2U leseva, ngakho-ke yini osesimweni se-server? Ngaphambi kokuphendula lo mbuzo, ake wethula kafushane i-server chassis.
Icala leseva libhekisela kwi-chassis yenethiwekhi enganikeza izinsizakalo ezithile. Izinsizakalo eziphambili ezinikeziwe zifaka: ukwamukelwa kwedatha kanye nokulethwa, ukugcinwa kwedatha kanye nokucutshungulwa kwedatha. Ngemigomo ye-layman, singaqhathanisa icala leseva ecaleni elikhethekile lekhompyutha ngaphandle komqaphi. Ngakho-ke icala lami lekhompyutha lingahle lisetshenziswe njengecala leseva? Ethiyori, icala le-PC lingasetshenziswa njengecala leseva. Kodwa-ke, i-server chassis isetshenziswa ngokuvamile ezimweni ezithile, njenge: amabhizinisi ezezimali, amapulatifomu ezitolo online, njll. Kulezi zimo, isikhungo sedatha esinezinkulungwane zamaseva singagcina futhi sicubungule imininingwane enkulu yedatha. Ngakho-ke, ikhompyutha yomuntu siqu ye-chassis ayikwazi ukufeza izidingo ezikhethekile ngokuya ngokusebenza, umkhawulokudonsa, kanye namakhono wokucubungula idatha. Icala leseva lingahlukaniswa ngokwesimo somkhiqizo, futhi lingahlukaniswa nge-Activation Server Case: Uhlobo olujwayelekile kakhulu lwe-server Case, elifana ne-cassis eyinhloko yekhompyutha. Lolu hlobo lwecala leseva lukhulu futhi luzimele, futhi alunankinga yokuphatha uhlelo lapho lusebenza ndawonye. Isetshenziswa ikakhulukazi amabhizinisi amancane ukwenza ibhizinisi. Icala le-RACK-MACKLED Case: Icala leseva elinokubukeka okufanayo nokuphakama ku-U. Lolu hlobo lwecala leseva luthatha isikhala esincane futhi kulula ukuphatha. Isetshenziswa ikakhulukazi kumabhizinisi ngesidingo esikhulu samaseva, futhi futhi kuyinto esetshenziswa kakhulu i-chassis yeseva. I-Server Chassis: Icala elifakwe ku-rack eliphakeme ngokuphakama okujwayelekile ngokubukeka, kanye icala leseva lapho amayunithi weseva yamakhadi amaningi angafakwa khona kuleli cala. Isetshenziswa kakhulu ezikhungweni ezinkulu zedatha noma izinkambu ezidinga i-computing enkulu, njengebhange kanye nezimboni zezezimali.
Uyini? Ekuhlukanisweni kwecala leseva, sifunde ukuthi ukuphakama kwecala leseva ye-rack kuse-U. Ngakho-ke, yini ngempela? U (isifinyezo seyunithi) yiyunithi emele ukuphakama kwecala leseva ye-rack. Usayizi onemininingwane we-U wenzelwe inhlangano ye-American Electronics Industries Association (EIA), 1U = 4.445 cm, 2u = 4.445 * 2 = 8.89 cm, njalonjalo. Awuyena ubunikazi bencwadi yeseva. Bekungonangempela isakhiwo se-rack esisetshenziselwa ukuxhumana nokushintshana, futhi kamuva sabhekiswa kamuva kuma-racks weseva. Njengamanje esetshenziswe njengezinga elifanelekile le-Server Rack Construction, kufaka phakathi osayizi abacacisiwe wesikulufa, ukuhlukaniswa komgodi, ojantshi, njll. Ukucacisa usayizi wecala leseva ngu-U usayizi we-Iron noma i-Aluminium. Kukhona izimbobo zesikulufa ezigodliwe kusengaphambili ngokuya nge-server chassis yamasayizi ahlukene kwi-rack, ihambisane nezimbobo zesikulufa secala leseva, bese likulungisa ngezikulufo. Usayizi ochazwe nguwe ububanzi (48.26 cm = amayintshi ayi-19) nokuphakama (ukuphindaphinda kwama-4.445 cm) wecala leseva. Ukuphakama nobukhulu becala leseva kususelwa ku-U, 1U = 4.445 cm. Ngoba ububanzi bangamasentimitha ayi-19, i-rack ehlangabezana nale mfuneko kwesinye isikhathi ibizwa ngokuthi "i-intshi engu-intshi."
