Ibyiciro bya seriveri
Iyo tuvuze ikibazo cya seriveri, dukunze kuvuga kubyerekeye 2U seriveri ya dosiye ya 4U ya seriveri, none U ni iki murubanza rwa seriveri?Mbere yo gusubiza iki kibazo, reka tumenye muri make seriveri ya chassis.
Seriveri yerekana ibikoresho byurusobe ibikoresho bishobora gutanga serivisi zimwe.Serivisi nyamukuru zitangwa zirimo: kwakira amakuru no gutanga, kubika amakuru no gutunganya amakuru.Mu magambo y’abalayiki, dushobora kugereranya dosiye ya seriveri na mudasobwa idasanzwe idafite monitor.Noneho dosiye yanjye ya mudasobwa yanjye nayo ishobora gukoreshwa nkurubanza rwa seriveri?Mubyigisho, dosiye ya PC irashobora gukoreshwa nkurubanza rwa seriveri.Nyamara, seriveri ya seriveri ikoreshwa muburyo bwihariye, nka: ibigo byimari, urubuga rwo guhaha kumurongo, nibindi. Muri ibi bihe, ikigo cyamakuru kigizwe nibihumbi n'ibihumbi bya seriveri gishobora kubika no gutunganya amakuru menshi.Kubwibyo, chassis ya mudasobwa yihariye ntishobora guhaza ibyifuzo byihariye mubijyanye nimikorere, umurongo mugari, hamwe nubushobozi bwo gutunganya amakuru.Urubanza rwa seriveri rushobora gushyirwa muburyo ukurikije imiterere yibicuruzwa, kandi birashobora kugabanywamo: umunara wa seriveri: ubwoko bwibisanzwe bwa seriveri, bisa na chassis nkuru ya mudasobwa.Ubu bwoko bwa seriveri ni nini kandi yigenga, kandi ntibyoroshye gucunga sisitemu mugihe dukorana.Ikoreshwa cyane cyane ninganda nto gukora ubucuruzi.Seriveri ya seriveri yubatswe: seriveri ifite isura imwe nuburebure muri U. Ubu bwoko bwa seriveri ifite umwanya muto kandi byoroshye kuyobora.Ikoreshwa cyane cyane mubigo bifite ibyifuzo byinshi kuri seriveri, kandi ni na seriveri ikoreshwa cyane.Seriveri ya seriveri: ikariso yashizwemo nuburebure busanzwe mubigaragara, hamwe na seriveri aho amakarita menshi yubwoko bwa seriveri ashobora kwinjizwa murubanza.Ikoreshwa cyane mubigo binini byamakuru cyangwa imirima isaba kubara kwinshi, nkamabanki ninganda zimari.
U ni iki?Mu byiciro bya seriveri, twamenye ko uburebure bwa dosiye ya rack iri muri U. None, U ni iki?U (ahinnye kubice) nigice kigaragaza uburebure bwa seriveri ya rack.Ingano irambuye ya U yateguwe n’ishyirahamwe ry’abanyamerika ry’inganda (EIA), 1U = cm 4.445, 2U = 4.445 * 2 = 8.89 cm, nibindi.U ntabwo ari patenti kubibazo bya seriveri.Ubusanzwe yari imiterere ya rack yakoreshejwe mu itumanaho no kungurana ibitekerezo, nyuma yaje kwerekanwa kuri seriveri.Kugeza ubu ikoreshwa nkibisanzwe muburyo bwa seriveri yubatswe, harimo ingano ya screw, ingano yumwobo, gariyamoshi, nibindi. Kugaragaza ubunini bwurubanza rwa seriveri na U bituma seriveri ya chassis mubunini bukwiye bwo gushyirwaho ibyuma cyangwa aluminium.Hano hari ibyobo byabitswe mbere ukurikije seriveri ya chassis yubunini butandukanye kuri rack, uyihuze nu mwobo wa screw ya dosiye ya seriveri, hanyuma uyikosore hamwe na screw.Ingano yagaragajwe na U ni ubugari (48.26 cm = santimetero 19) n'uburebure (kugwiza cm 4.445) ya seriveri.Uburebure n'ubunini bwa dosiye ya seriveri ishingiye kuri U, 1U = 4.445 cm.Kuberako ubugari ari santimetero 19, rack yujuje iki cyifuzo rimwe na rimwe yitwa "rack-19-rack."
