Server khib kev txawj ntse, U thiab 19-nti

Hauv cov chaw zov me nyuam, cov khoom siv sib txuas lus, thiab kev tswj hwm kev lag luam, cov khoom siv hluav taws xob yog ib feem tseem ceeb ntawm cov txheej txheem rau vaj tse thiab kev tiv thaiv cov khoom siv network. Txhawm rau kom muaj kev sib koom ua ke ntawm cov khoom siv los ntawm cov tuam txhab sib txawv, kev lag luam feem ntau siv cov qauv kev sib koom ua ke, nrog rau ob lub ntsiab lus tseem ceeb yog "U" qhov siab thiab "19-inch racks standard." Kev nkag siab txog cov ntsiab lus tseem ceeb no pab xaiv cov cuab yeej zoo dua, kev npaj khib nyiab, thiab cov ntaub ntawv chaw teeb tsa. Hauv qhov chaw xa tawm tiag tiag, txawm tias nws yog lub khoos phis tawj server khib siv nyob rau hauv lub chaw lag luam-theem cov ntaub ntawv chaw lossis lub network me me rau ib puag ncig me me, tib lub khib loj qhov tshwj xeeb tau ua raws.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ua ntej, nws yuav tsum nkag siab lub ntsiab lus ntawm "U." "U" yog tus qauv chav tsev rau cov khoom siv server qhov siab, tus ntawv luv rau Unit, tsim los ntawm Electronic Industries Association (EIA) thiab dav siv hauv khib-mount khoom tsim. Tus qauv qhia tias 1U=44.45mm (kwv yees li 1.75 ntiv tes); yog li ntawd, qhov siab ntawm khib-mount cov khoom xws li servers, keyboards, thiab cia khoom feem ntau yog qhia hauv nU. Piv txwv li, 1U server yog 44.45mm siab, 2U server yog 88.9mm siab, thiab lwm yam. Cov mounting rails nyob rau hauv lub khib yog cim nrog U-zoo li tus cim qhov siab kom tso cai rau cov txheej txheem installation. Hauv cov chaw IT me me, qee cov lag luam lossis cov chaw sim hauv tsev kuj tseem siv 6U server racks lossis 9U phab ntsa mount racks los xa cov routers, keyboards, lossis cov server me me.

 

Qhov "19-nti standard" yog hais txog qhov dav dav dav rau cov khoom siv khib nyiab . 19 ntiv tes txhais tau hais tias tus qauv dav ntawm cov khoom siv mounting vaj huam sib luag yog kwv yees li 482.6mm. Cov cuab yeej siv feem ntau muaj pob ntseg pob ntseg ntawm ob sab, nrog qhov dav dav ntawm kwv yees li 465 hli ntawm qhov sib dhos rau kev sib dhos nrog cov khib nyiab thiab cov ntsia hlau ruaj ntseg. Vim tias tus qauv no tau txais kev pom zoo thoob ntiaj teb, racks feem ntau hu ua 19-nti racks. Cov qauv tsim qauv no ua kom ntseeg tau tias cov servers, keyboards, lossis cov khoom siv network los ntawm ntau hom tuaj yeem ntsia tau rau hauv tib lub racking mount enclosure lossis server enclosure, ua tiav kev sib raug zoo thiab hloov tau yooj yim.

 

Hauv kev siv tswv yim, khib qhov siab feem ntau yog qhia hauv U units, xws li cov ntaub ntawv chaw racks uas yog 42U lossis 48U racks. Raws li txoj cai, 42U khib tuaj yeem ua raws li 42 1U khoom siv. Txawm li cas los xij, hauv kev xa tawm tiag tiag, txhawm rau kom muaj chaw txaus rau cov cua sov dissipation, cabling, thiab kev saib xyuas, tsuas yog 10 mus rau 20 servers lossis cov khoom siv network feem ntau raug teeb tsa. Tsis tas li ntawd, nyob ntawm daim ntawv thov ib puag ncig, racks yog tsim los nrog cov qauv sib txawv, xws li cov khoom siv khib nyiab rau hauv tsev lossis cov chaw ua haujlwm me me, lossis cov ntaub ntawv me me rau qhov chaw ib puag ncig.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ntxiv nrog rau qhov siab thiab dav, cov neeg rau zaub mov racks kuj tuaj yeem sib txawv qhov tob kom haum rau ntau qhov ntau thiab tsawg. Feem ntau racks qhov tob feem ntau yog nyob nruab nrab ntawm 400mm thiab 800mm, nrog qee qhov siab -kev ua haujlwm server racks txawm tob dua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv loj cia thiab siab - ceev servers. Nyob rau hauv ntug kev xam los yog faib network xa tawm scenarios, cov cuab yeej yuav raug ntsia rau hauv network txee phab ntsa mounts lossis phab ntsa-cov ntaub ntawv mounted. Cov phab ntsa no-mounted qauv txuag cov ntaub ntawv chaw chaw thiab ua kom yooj yim rau kev tswj cov cabling.

 

Raws li txoj cai, tus txheej txheem neeg rau zaub mov khib feem ntau muaj cov txheej txheem yooj yim, cov cuab yeej txuas txuas, cov txheej txheem cabling, thiab cov cua txias. Tsim kom muaj qhov cua zoo yog qhov tseem ceeb rau kev ua haujlwm ruaj khov; Yog li ntawd, ntau cov neeg rau zaub mov racks tau nruab nrog lub qhov rooj mesh, kiv cua modules, los yog airflow channels. Qee qhov chaw tshwj xeeb hauv daim ntawv thov, xws li cov chaw lag luam lossis cov suab nrov- cov cheeb tsam tseem ceeb, kuj tseem siv cov khoom siv khib nyiab xws li soundproof server racks lossis cov txee sab nraum zoov kom ua tau raws li kev txo suab nrov, kev tiv thaiv plua plav, lossis kev xav tau ib puag ncig sab nraum zoov.

 

Kev nkag siab txog kev sib raug zoo ntawm U- qhov siab thiab khib nyiab yog qhov tseem ceeb hauv kev npaj cov khoom siv hauv chaw xa khoom. Piv txwv li, 18U neeg rau zaub mov racks feem ntau yog siv rau kev tswj hwm hauv nruab nrab ntawm me me mus rau nruab nrab- cov khoom siv network loj, thaum cov chaw zov me nyuam loj feem ntau siv ntau dua - cov khoom tshwj xeeb. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txawm hais tias khib qhov siab yog qhia los ntawm tus naj npawb ntawm U units, tsis muaj xws li "1U khib"; U unit tsuas yog siv los piav txog qhov siab ntawm cov khoom siv. Racks lawv tus kheej feem ntau yog li ntawm 6U txog 48U, thiab cov neeg siv yuav tsum tau npaj raws li tus naj npawb ntawm cov khoom siv, qhov xav tau cua txias, thiab qhov chaw nthuav dav yav tom ntej.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nrog rau kev txhim kho huab huab, cov chaw khaws ntaub ntawv, thiab kev suav ntug, cov txheej txheem khib nyiab tau dhau los ua ib qho tseem ceeb ntawm IT infrastructure. Txawm hais tias siv siab -qhov ceev ceev server ib puag ncig rau cov lag luam loj lossis tsim kev sib txuas lus yooj yim rau cov lag luam me thiab nruab nrab- loj, ua raws li 19-inch standard thiab U-height specifications tuaj yeem txhim kho cov cuab yeej siv tau zoo, kev teeb tsa kev ua haujlwm, thiab kev saib xyuas yooj yim.

 

Thaum lub sij hawm installation ntawm server racks thiab network khoom, ruaj khov thiab txhim khu kev qha kev sib txuas yog qhov tseem ceeb sib npaug. Cov khoom siv hauv cov khib nyiab feem ntau xav tau cov qauv tshwj xeeb mounting kom ruaj ntseg thaum lub sij hawm ntev - ua haujlwm thiab tu. Raws li cov kws tshaj lij kev tsim khoom ntawm cov khoom siv hlau, peb muab siab -precision mounting tivthaiv kev daws teeb meem rauserver racks, network racks, thiab cov khoom siv sib txuas lus, suav nrog cov khib nyiab fasteners, cov khoom sib txuas, thiab cov khoom siv mounting Cheebtsam. Cov khoom no tau siv dav hauv cov neeg rau zaub mov racks rau kev muag khoom, khoos phis tawj server racks, thiab ntau lub rack mount enclosure systems, muab kev txhawb nqa cov qauv txhim khu kev qha thiab ntev - lub sijhawm ua haujlwm ruaj khov rau cov chaw khaws ntaub ntawv thiab cov khoom siv sib txuas lus.
