Kev faib tawm cov neeg rau zaub mov chassis
Thaum xa mus rau rooj plaub rau zaub mov, peb feem ntau tham txog 2U neeg rau zaub mov muaj ntaub ntawv 4U server. Ua ntej teb cov lus nug no, cia luv luv qhia tus neeg rau zaub mov chassis.
Cov ntaub ntawv Server yog hais txog cov cuab yeej siv hluav taws xob chassis uas tuaj yeem muab qee yam kev pabcuam. Cov kev pabcuam tseem ceeb tau muab: Cov ntaub ntawv txais tos thiab xa khoom, cov ntaub ntawv khaws cia thiab cov ntaub ntawv ua haujlwm. Nyob rau hauv Layman cov lus, peb tuaj yeem sib piv cov ntaub ntawv rau zaub mov rau cov ntaub ntawv tshwj xeeb uas tsis muaj saib xyuas. Yog li kuv tus kheej lub computer cov ntaub ntawv tseem raug siv ua rooj plaub server? Hauv kev tshawb xav, ib qhov xwm txheej pc tuaj yeem siv ua rooj plaub server. Txawm li cas los xij, cov neeg rau zaub mov chassis feem ntau siv nyob rau hauv cov xwm txheej tshwj xeeb, thiab cov ntaub ntawv kev lag luam, cov ntaub ntawv online muaj peev xwm khaws thiab ua cov ntaub ntawv loj ntawm cov ntaub ntawv. Yog li, tus kheej lub computer chassis tsis tuaj yeem ua raws li cov kev xav tau tshwj xeeb hauv kev ua tau zoo, bandwidth, thiab cov ntaub ntawv muaj peev xwm. Cov ntaub ntawv rau cov ntaub ntawv tiv thaiv raws li cov khoom lag luam, thiab tuaj yeem faib ua: Ntau hom neeg rau zaub mov, zoo ib yam li lub mainframe chassis ntawm lub khoos phis tawm. Hom no yog cov neeg rau zaub mov muaj loj thiab ywj siab, thiab nws tsis yooj yim los tswj hwm lub kaw lus thaum ua haujlwm ua ke. Nws yog tsuas yog siv los ntawm kev lag luam me me los ua kev lag luam. Rack-mounted server xwm txheej: ib qho tsos server nrog cov khaub ncaws zoo nkauj thiab qhov siab hauv U. Cov hom neeg rau zaub mov me me thiab yog ib qho yooj yim los tswj hwm. Nws yog tsuas yog siv rau hauv kev lag luam nrog kev thov loj rau cov servers, thiab nws kuj yog cov neeg rau zaub mov feem ntau ntawm cov neeg rau zaub mov chassis. Cov neeg rau zaub mov chassis: ib qho teeb meem khib uas muaj qhov pom ntawm qhov tsos, thiab cov khoom siv server nyob rau hauv ntau daim npav-hom server tso rau hauv rooj plaub. Nws yog tsuas yog siv nyob rau hauv cov chaw nruab nrab loj lossis cov teb uas xav tau cov lej loj, xws li nyiaj txiag thiab kev lag luam nyiaj txiag.
Koj yog dab tsi? Hauv kev faib tawm ntawm cov ntaub ntawv server, peb tau kawm hais tias qhov siab ntawm lub khib server cov ntaub ntawv yog nyob rau hauv U. Yog li, dab tsi yog koj? U (cov lus luv rau chav nyob) yog ib chav uas sawv cev rau qhov siab ntawm cov khib nyiab. Cov ncauj lus loj ntawm koj yog tsim los ntawm American Electronics Industries Association (EIA), 1U = 4.445 cm, 2U = 4.445 * 8.89 cm, thiab lwm yam. U tsis yog patent rau cov ntaub ntawv so neeg rau zaub mov. Nws yog Ameslikas cov qauv khib uas siv rau kev sib txuas lus thiab kev sib pauv, thiab tom qab tau hais txog cov neeg rau zaub mov racks. Tam sim no siv los ua tus qauv rau neeg rau zaub mov, suav nrog cov ntsia hlau sib nrug, thiab qhia kom meej rau kev teeb tsa kom raug rau cov hlau lossis txhuas racks. Muaj cov ntsia hlau qhov tseem ceeb ua ntej raws li cov neeg rau zaub mov chassis ntawm qhov sib txawv ntawm cov duab raj ntawm cov neeg rau zaub mov, thiab tom qab ntawd kho nws nrog screws. Qhov loj uas tau teev tseg los ntawm koj yog qhov dav (48.26 cm = 19 nti) thiab qhov siab (muaj ntau yam ntawm 4.445 cm) ntawm rooj plaub rau zaub mov. Qhov siab thiab tuab ntawm cov ntaub ntawv rau zaub mov yog raws li U, 1U = 4.445 cm. Vim tias qhov dav yog 19 nti, ib lub khib uas ua tau raws li qhov yuav tsum tau ua qee zaum qee zaum hu ua "khib."
