Peb feem ntau tau hnov ntawm fiber ntau optichloovthiab fiber optic transceivers. Ntawm lawv, fiber optichloovyog high-speed network kis tau tus mob relay khoom, kuj hu ua fiber channelhloovthiab SANhloov. Piv nrog rau qhov qubhloov, 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 optichloov. Ib tug yog FChloovsiv los txuas rau kev khaws cia. Lwm qhov yog Ethernethloov, qhov chaw nres nkoj yog optical fiber interface, thiab cov tsos yog tib yam li cov hluav taws xob zoo tib yam interface, tab sis hom interface yog 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 ntau optichloov!
1.core-theem fiber ntau optic keyboards
Qhov hu ua core-levelhloov(tseem hu ua cov thawj coj) feem ntau nyob hauv nruab nrab ntawm SAN loj, txuas ob peb ntughloovrau ib leeg los tsim ib lub SAN network nrog ntau pua chaw nres nkoj. Lub hauv paushloovkuj tseem siv tau los ua ib qho standalonehloovlos yog ntughloov, tab sis nws cov kev ua haujlwm zoo dua qub thiab cov qauv sab hauv ua rau nws ua haujlwm zoo dua hauv qhov chaw cia khoom tseem ceeb. Lwm cov haujlwm ntawm lub hauv paushloovkuj 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 nohloovyog tsim kom muaj kev pab cuam loj dua thiab muab bandwidth ntau dua. 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, core fiber ntau keyboards feem ntau siv kub-swappable Circuit Court boards raws li "hom hniav": ntev li ntev tau.hloovboard 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-redundancyhloovyog redundant, uas tshem tawm tag nrho cov ntsiab lus ntawm kev ua tsis tiav thiab lav lub sijhawm ntev heev. 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 nohloovmuaj ntau lub logic circuits los daws cov teeb meem kho vajtse hauv lubhloov. Lub hauv paushloovhauv fiber optichloovmuab 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 ntau optichloov
Fiber optic keyboards muab lub peev xwm los cascade ntauhloovmus rau hauv ib tug loj-scale Npuag. Los ntawm kev txuas ib lossis ntau qhov chaw nres nkoj ntawm ob lub keyboards, tag nrho cov chaw nres nkoj txuas nroghloovtuaj 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 cascading keyboards, loj, virtual, faibhloovtuaj yeem tsim tau, thiab qhov kev ncua deb nws tuaj yeem hla tau loj heev. Ib daim ntaub tsim los ntawm ntau lub keyboards zoo li ib daim ntaub uas muaj cov keyboards cais. Ports ntawm tag nrho covhloovtuaj yeem saib thiab nkag tau 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 sib faib yog kom tau txais cov bandwidth ntawm kev sib txuas ntawm covhloov. Qhov txiaj ntsig zoo ntawm ob qhov chaw nres nkoj yog cuam tshuam los ntawm kev siv bandwidth zoo ntawm kev sib txuas ntawm covhloov, 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. Pawg neeg ua haujlwmhloovtau siv ntau txoj hauv kev, tab sis thaj 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 Channelhloov. 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-theemhloov
Daim ntawv thov nkag-theem hloov hauv fiber ntau optichloovFeem ntau 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 neeg feem ntau tsis yuav nkag-theemhloovcais, tab sis feem ntau yuav lawv ua ke nrog rau lwm theem ntawm cov keyboards los tsim kom tiav 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.
