Kurongwa kwe server chassis
Kana tichitaura nezve server kesi, isu tinowanzo kutaura nezve 2U server kesi kana 4U server kesi, saka chii chiri U mune server kesi?Tisati tapindura mubvunzo uyu, ngatizivise muchidimbu server chassis.
A server kesi inoreva network network chassis inogona kupa mamwe masevhisi.Iwo masevhisi makuru anopihwa anosanganisira: kugamuchira data uye kuendesa, kuchengetedza data uye kugadzirisa data.Mukutaura kwe layman, tinogona kufananidza sevha kesi kune yakakosha komputa kesi isina cheki.Saka ini pachangu komputa kesi yangu inogona kushandiswawo sevhavha kesi?Mune dzidziso, PC kesi inogona kushandiswa sevhavha kesi.Nekudaro, server chassis inowanzo shandiswa mune chaiwo mamiriro, akadai se: mabhizinesi emari, online ekutenga mapuratifomu, nezvimwe. Muzviitiko izvi, nzvimbo yedata ine zviuru zvemaseva inogona kuchengeta uye kugadzirisa huwandu hukuru hwe data.Naizvozvo, iyo yekombuta chassis haigone kusangana nezvinodiwa zvakakosha maererano nekuita, bandwidth, uye kugona kugadzirisa data.Iyo server kesi inogona kuverengerwa zvinoenderana neyakagadzirwa chimiro, uye inogona kukamurwa kuita: tower server kesi: iyo yakajairika mhando ye server kesi, yakafanana neye mainframe chassis yekombuta.Iyi mhando ye server kesi yakakura uye yakazvimiririra, uye hazvina kunaka kubata sisitimu kana uchishanda pamwechete.Inonyanya kushandiswa nemabhizinesi madiki kuita bhizinesi.Rack-mounted server case: sevha kesi ine chitarisiko cheunifomu uye kureba muU. Rudzi urwu rwekesi yeseva inotora nzvimbo diki uye iri nyore kubata.Inonyanya kushandiswa mumabhizinesi ane kudiwa kukuru kwemaseva, uye zvakare ndiyo inonyanya kushandiswa server chassis.Server chassis: rack-yakaiswa kesi ine mwero wakareba mukutaridzika, uye sevha kesi umo akawanda kadhi-mhando sevha mayunitsi anogona kuiswa mukesi.Inonyanya kushandiswa munzvimbo huru dze data kana minda inoda yakakura-yakawanda komputa, senge mabhengi uye maindasitiri emari.
Chii chinonzi U?Muchikamu che server kesi, takadzidza kuti kureba kweiyo rack server kesi iri muU. Saka, chii chaizvo chinonzi U?U (pfupiso yeyuniti) iyuniti inomiririra kureba kwereki server kesi.Ukuru hwakadzama hweU hwakagadzirwa neAmerican Electronics Industries Association (EIA), 1U = 4.445 cm, 2U = 4.445 * 2 = 8.89 cm, zvichingodaro.U haisi patent ye server kesi.Pakutanga yaive rack chimiro chaishandiswa kutaurirana uye kuchinjana, uye yakazotaurwa kune server racks.Parizvino inoshandiswa seyakajairwa chiyero chekuvaka sevha rack, kusanganisira saizi dzakatsanangurwa, maburi, njanji, nezvimwe. Kutsanangura saizi yekesi yeseva neU inochengeta sevha chassis pakukura kwayo kwekuiswa pasimbi kana aluminium racks.Kune screw maburi akachengeterwa kumberi maererano neserver chassis yehukuru hwakasiyana pane rack, igadzirise nemaburi escrew evhavha kesi, uye wozoigadzirisa nema screws.Saizi inotsanangurwa neU ihupamhi (48.26 cm = 19 inches) uye kureba (yakawanda ye4.445 cm) ye server kesi.Kureba nekukora kwekesi yeseva kunobva paU, 1U = 4.445 cm.Nokuti hupamhi huri 19 inches, rack inosangana nezvinodiwa dzimwe nguva inonzi "19-inch rack."
