Peb feem ntau tau hnov txog fiber ntau optic keyboards thiab fiber optic transceivers.Ntawm lawv, fiber ntau optic keyboards yog high-speed network kis tau tus mob relay khoom, kuj hu ua fiber channel keyboards thiab SAN keyboards.Piv nrog cov keyboards zoo tib yam, lawv siv fiber ntau optic cables ua cov khoom sib kis.nruab nrab.Qhov zoo ntawm optical fiber kis tau tus mob yog ceev ceev thiab muaj zog tiv thaiv kev cuam tshuam muaj peev xwm.Muaj ob hom fiber ntau optic keyboards.Ib qho yog FC hloov siv los txuas rau kev khaws cia.Lwm qhov yog Ethernet hloov, qhov chaw nres nkoj yog qhov sib txuas ntawm fiber ntau optical, thiab cov tsos zoo ib yam li cov hluav taws xob zoo tib yam, tab sis hom interface sib txawv.
Muaj peb hom fiber ntau keyboards: nkag-theem keyboards, workgroup-level fiber keyboards, thiab core-level fiber keyboards.Yog li cia peb pib nrog thawj core-theem fiber optic hloov!
1.core-theem fiber ntau optic keyboards
Lub npe hu ua core-theem keyboards (tseem hu ua cov thawj coj) feem ntau nyob hauv nruab nrab ntawm SAN loj, txuas ob peb lub ntug hloov mus rau ib leeg los tsim SAN network nrog ntau pua chaw nres nkoj.Cov tub ntxhais hloov pauv tuaj yeem siv tau los ua ib qho kev hloov pauv lossis hloov pauv hloov pauv, tab sis nws cov haujlwm txhim kho thiab cov qauv sab hauv ua rau nws ua haujlwm zoo dua hauv qhov chaw khaws cia tseem ceeb.Lwm lub luag haujlwm ntawm cov tub ntxhais hloov pauv tseem suav nrog: kev txhawb nqa rau cov txheej txheem uas tsis yog kho qhov muag fiber ntau (xws li InfiniBand), kev txhawb nqa rau 2Gbps Fiber Channel, thiab cov kev pabcuam kho qhov muag siab heev (piv txwv li: kev ruaj ntseg, lub cev thiab cov thav duab lim, thiab lwm yam).Core-level fiber optic keyboards feem ntau muab ntau qhov chaw nres nkoj, los ntawm 64 chaw nres nkoj mus rau 128 chaw nres nkoj thiab ntau dua.Nws siv kev sib txuas sab hauv dav heev rau txoj kev cov ntaub ntawv thav ntawv nrog qhov siab tshaj plaws bandwidth.Lub hom phiaj ntawm kev siv cov keyboards no yog tsim kom muaj kev pabcuam loj dua thiab muab ntau dua bandwidth.Lawv tau tsim los rau txoj kev teeb tsa cov teeb liab kom sai li sai tau ntawm ntau qhov chaw nres nkoj nrog lub sijhawm luv tshaj plaws.Tsis tas li ntawd, cov keyboards tseem ceeb feem ntau siv cov khoom siv hluav taws xob kub sib hloov raws li "hom hniav": ntev npaum li lub rooj tsavxwm hloov tau muab tso rau hauv lub txee, cov haujlwm tshiab tuaj yeem ntxiv, thiab kev saib xyuas online kuj tuaj yeem ua tau.Yuav tsum tau nthuav dav.Ntau qhov tseem ceeb-theem keyboards tsis txhawb nqa arbitrated loops lossis lwm yam khoom siv txuas ncaj qha.Lawv tsuas yog mob siab txog kev hloov pauv tseem ceeb.Vim tias muaj yog qhov tseem ceeb tshaj plaws nyob rau hauv tag nrho ib puag ncig, tib neeg txaus siab siv nyiaj ntau dua rau kev rov ua dua tshiab.Tag nrho cov khoom ntawm high-redundancy keyboards yog redundant, uas tshem tawm tag nrho cov ntsiab lus ntawm tsis ua hauj lwm thiab guarantees lub sij hawm ntev heev Uptime.Cov kev siv nyiaj rov qab no feem ntau yog siv rau cov khoom siv rov qab muaj zog, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob rov ua dua, thiab software los tswj kom muaj.Hom kev hloov no muaj ntau lub logic circuits los daws cov teeb meem kho vajtse hauv qhov hloov.Cov keyboards tseem ceeb hauv fiber optic keyboards muab qhov kev ntseeg siab tshaj plaws thiab qhov chaw nres nkoj ceev.Nyob rau hauv ib lub chaw cov ntaub ntawv nrog ib tug loj npaum li cas ntawm Fiber Channel infrastructure, xws li cov khoom yog yuav luag invulnerable, centralized cia keyboards.Yog li ntawd, rau feem ntau cov kev sib txuas siab, koj yuav tsum xaiv lub network dual-channel tsim los ntawm cov tub ntxhais fiber ntau hloov.
2.workgroup-theem fiber optic keyboards
Fiber optic keyboards muab lub peev xwm los cascade ntau lub keyboards mus rau hauv cov ntaub loj loj.Los ntawm kev sib txuas ib lossis ntau qhov chaw nres nkoj ntawm ob lub keyboards, txhua qhov chaw nres nkoj txuas nrog qhov hloov pauv tuaj yeem pom cov duab tshwj xeeb ntawm lub network, thiab txhua qhov ntawm cov ntaub no tuaj yeem sib txuas lus nrog lwm cov nodes.Los ntawm cov keyboards cascading, qhov loj, virtual, faib hloov pauv tuaj yeem tsim tau, thiab qhov kev ncua deb nws tuaj yeem nthuav dav heev.Ib daim ntaub tsim los ntawm ntau lub keyboards zoo li ib daim ntaub uas muaj cov keyboards cais.Cov chaw nres nkoj ntawm txhua qhov hloov pauv tuaj yeem pom thiab nkag mus zoo li txhua qhov chaw nres nkoj ntawm cov ntaub li nkag mus rau hauv cov keyboards hauv zos.Lub koom haum lub npe neeg rau zaub mov thiab kev tswj hwm kev pabcuam pub saib thiab hloov kho txhua cov ntaub ntawv Fabric los ntawm ib qho kev sib tshuam.Ib qho tseem ceeb hauv kev tsim cov ntaub ntawv xa tawm yog kom tau txais cov bandwidth ntawm kev sib txuas ntawm cov keyboards.Qhov txiaj ntsig zoo ntawm ob qhov chaw nres nkoj yog cuam tshuam los ntawm kev siv bandwidth zoo ntawm kev sib txuas ntawm cov keyboards, thiab nws yuav tsum tau siv ntau qhov kev sib txuas ntawm cov keyboards kom tswj tau qhov tsim nyog bandwidth.Workgroup Fiber Channel keyboards muaj ntau thiab ntau yam.Workgroup keyboards yog siv nyob rau hauv ntau txoj kev, tab sis qhov chaw siv dav tshaj plaws yog SAN me me.Cov keyboards zoo li no tuaj yeem txuas ua ke los ntawm cov kab sib txuas ntawm cov keyboards kom muab cov chaw nres nkoj ntau dua.Cov kab sib txuas ntawm cov keyboards tuaj yeem tsim tau ntawm txhua qhov chaw nres nkoj ntawm Fiber Channel hloov.Txawm li cas los xij, yog tias koj npaj yuav siv cov khoom lag luam los ntawm ntau tus neeg muag khoom, koj yuav tsum xyuas kom meej tias cov khoom siv sib cuam tshuam.
3. nkag-theem keyboards
Daim ntawv thov kev nkag-theem hloov hauv fiber ntau optic keyboards yog tsom rau hauv pawg ua haujlwm me me nrog 8 mus rau 16 chaw nres nkoj.Nws yog qhov tsim nyog rau lub sijhawm nrog tus nqi qis thiab xav tau me ntsis rau kev nthuav dav thiab kev tswj hwm.Lawv feem ntau siv los hloov cov hubs, uas tuaj yeem muab ntau dua bandwidth thiab muab kev sib txuas zoo dua li cov hubs.Cov tib neeg feem ntau tsis yuav cov keyboards nkag mus sib cais, tab sis feem ntau yuav lawv ua ke nrog lwm qib ntawm cov keyboards los tsim cov kev daws teeb meem.Nkag-theem fiber optic keyboards muab ib theem txwv ntawm qhov chaw nres nkoj cascading peev xwm.Yog tias cov neeg siv siv cov khoom siv qis kawg nkaus xwb, lawv yuav ntsib teeb meem kev tswj hwm.
