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."
