Ukuhlelwa kwe-chassis yomncedisi
Xa sibhekisa kwimeko yeseva, sihlala sithetha nge-2U yeseva yecala okanye i-4U yeseva yeseva, ke ithini i-U kwimeko yeseva?Phambi kokuba uphendule lo mbuzo, makhe sazise ngokufutshane i-chassis yomncedisi.
Imeko yeseva ibhekisa kwisixhobo se-chassis senethiwekhi enokubonelela ngeenkonzo ezithile.Iinkonzo eziphambili ezinikezelwayo ziquka: ukwamkelwa kunye nokuhanjiswa kwedatha, ukugcinwa kwedatha kunye nokucubungula idatha.Ngokwemigaqo ye-layman, sinokuthelekisa i-server ye-server kwimeko ekhethekileyo yekhompyutheni ngaphandle kwemonitha.Ke ngaba imeko yam yekhompyuter ingasetyenziswa njengetyala leseva?Kwithiyori, imeko yePC ingasetyenziswa njengemeko yeseva.Nangona kunjalo, i-server chassis isetyenziswa ngokubanzi kwiimeko ezithile, ezinje: amashishini emali, amaqonga okuthenga kwi-intanethi, njl.njl. Kwezi meko, iziko ledatha elibandakanya amawaka eeseva linokugcina kwaye liqhube izixa ezikhulu zedatha.Ke ngoko, i-chassis yekhompyuter yomntu ayinakuhlangabezana neemfuno ezikhethekileyo ngokwendlela yokusebenza, i-bandwidth, kunye nobuchule bokwenza idatha.I-server ye-server ingahlelwa ngokwemilo yemveliso, kwaye inokwahlulwa ibe: i-server ye-tower server: uhlobo oluqhelekileyo lwe-server ye-server, efana ne-mainframe chassis yekhompyutheni.Olu hlobo lwemeko yomncedisi likhulu kwaye luzimeleyo, kwaye alukho lula ukulawula inkqubo xa usebenza kunye.Isetyenziswa ikakhulu ngamashishini amancinci ukwenza ishishini.Imeko ye-server efakwe kwi-Rack: i-server enenkangeleko efanayo kunye nobude kwi-U. Olu hlobo lwemeko ye-server ithatha indawo encinci kwaye kulula ukuyilawula.Isetyenziswa ikakhulu kumashishini anemfuno enkulu yeeseva, kwaye ikwayeyona chassis isetyenziswa ngokuqhelekileyo.I-chassis yomncedisi: i-rack-mounted case enobude obuqhelekileyo ngenkangeleko, kunye ne-server case apho iiyunithi ezininzi ze-server zohlobo lwekhadi zingafakwa kwimeko.Isetyenziswa kakhulu kumaziko amakhulu edatha okanye iindawo ezifuna i-computing enkulu, njengeebhanki kunye namashishini emali.
Yintoni u-U?Kuhlelo lwemeko yeseva, sifunde ukuba ukuphakama kwetyala le-rack server kuku-U. Ke, yintoni kanye kanye i-U?U (ushunqulelo lweyunithi) yiyunithi emele umphakamo wetyala le-rack server.Ubungakanani obucacileyo be-U buqulunqwe yi-American Electronics Industries Association (EIA), 1U = 4.445 cm, 2U = 4.445 * 2 = 8.89 cm, njalo njalo.U-U ayilolungelo lomenzi kwityala leseva.Ekuqaleni yayisisakhiwo se-rack esisetyenziselwa unxibelelwano kunye notshintshiselwano, kwaye kamva sabhekiswa kwiiracks zeseva.Ngoku isetyenziswa njengomgangatho ongekho sikweni wolwakhiwo lwerekhi yeseva, kubandakanywa ubungakanani obukhankanyiweyo bezikhonkwane, isithuba somngxunya, iintsimbi, njl.njl. Ukucacisa ubungakanani bemeko yeseva nge-U igcina i-chassis yomncedisi kubungakanani obufanelekileyo bokufakelwa kwintsimbi okanye iirakhi zealuminiyam.Kukho imingxunya ye-Screw egcinwe kwangaphambili ngokwe-server ye-chassis yobukhulu obahlukeneyo kwi-rack, ilungelelanise kunye nemingxuma ye-screw ye-server, kwaye uyilungise ngezikrufu.Ubungakanani obuchazwe ngu-U ububanzi (48.26 cm = 19 intshi) kunye nobude (ubuninzi be-4.445 cm) yecala lomncedisi.Ubude kunye nobukhulu becala leseva lusekwe kwi-U, 1U=4.445 cm.Ngenxa yokuba ububanzi buyi-intshi ezili-19, i-rack ehlangabezana nale mfuneko ngamanye amaxesha ibizwa ngokuba "yi-19-intshi yokubeka."
