Fiber Channel (FC, FibreChannel) raws tu qauv yog cov txheej txheem rau kev sib txuas lus sib txuas lus teev tseg los ntawm American National Standards rau ceev ceev, tsis tshua muaj latency, thiab cov lej yuam kev tsawg. Nws tuaj yeem muab cov ntaub ntawv xa mus sai rau cov khoom siv cia, IP cov ntaub ntawv network, thiab cov kwj suab. Technology pob txha. Nrog rau kev siv Fiber Channel hauv kev lag luam sib txawv, raws li Fiber Channel raws tu qauv, Fiber Channel raws tu qauv pawg siv hauv kev lag luam sib txawv tau tsim. Cov txheej txheem no txhawb nqa thiab txhim kho Fiber Channel raws tu qauv. Hauv Is Taws Nem ntawm thaj chaw kho qhov muag fiber ntau, vim tias ntau cov ntaub ntawv yuav tsum raug xa mus, cov tsoos TCP / IP network tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Qhov qis latency thiab qis yuam kev code ntawm fiber ntau channel raws tu qauv yog haum rau cov ntsiab lus thiab taw tes qauv. Ring topology thiab interchange Cov qauv topological ua tau zoo heev ntawm kev siv Internet hauv thaj chaw cia. Txuas txhua lub hom phiaj ntawm lub tshuab thiab cov khoom siv raws li qhov hloov kho qhov muag fiber ntau, thiab cov cascade nyob rau hauv nruab nrab ntawm qhov hloov kho qhov muag, tuaj yeem nthuav dav kev lag luam nplai ntawm Is Taws Nem hauv thaj chaw cia khoom. Fiber Channel muaj kev sib kis tau zoo, tsis tshua muaj latency, thiab muaj zog scalability.
Fiber Channel kis tau tus mob: Qhov kev ceev ntawm optical fiber channel tshuab xa cov ntaub ntawv ntawm cov khoom yog 1.0625Gbit / s, uas tseem hu ua FullSpeed. Tsis tas li ntawd, kuj tseem muaj 1/2, 1/4, thiab 1/8 npaug ntawm qhov ceev. Lawm, muaj 2 npaug ntawm cov ntaub ntawv xov xwm kis tus nqi (2.125Gbit / s) thiab 4 npaug ntawm cov ntaub ntawv xov xwm kis tus nqi (4.25Gbit / s). ). Nrog rau kev txiav txim siab tag nrho ntawm 8B / 10B tus lej thiab lwm yam nuj nqis, fiber ntau channel kis tus nqi ntawm cov khoom thauj ntawm qhov nrawm yog 100MB / s.
Topological qauv nrog muaj zog expansion muaj nuj nqi thiab saj zawg zog: Fiber Channel technology muaj zoo expansion cov yam ntxwv, thiab cov txheeb ze SCSI channel tsuas muaj peev xwm mus txog 15 chaw, thiab fiber ntau arbitration nplhaib txoj kev yuav haum mus txog rau 126 tshuab thiab khoom siv. , Thiab cov qauv hloov pauv tuaj yeem ua tau raws li ntau tshaj 60,000 tshuab thiab khoom siv. Thiab vim hais tias cov fiber ntau channel lub cev kev sib txuas topology yog me ntsis mus rau lub ntsiab lus, cov qauv topological xws li kev txiav txim siab lub nplhaib txoj kev thiab cov pob ntawv hloov cov qauv, cov khoom siv fiber ntau kuj tuaj yeem tsim qhov chaw cia hauv Internet raws li fiber ntau arbitration nplhaib txoj kev los yog kev sib hloov qauv. SCSI thev naus laus zis tsuas yog muaj qhov taw tes-to-point topology. Nws tsis yog qhov nyuaj kom pom tias Fiber Channel thev naus laus zis tsis tsuas yog muaj peev xwm nthuav dav kev ua haujlwm, tab sis kuj muaj qhov hloov pauv hloov pauv.
Standardized Fiber Channel Protocol Projection: Fiber Channel tuaj yeem siv los ua cov ntaub ntawv xov xwm sib kis nruab nrab rau ntau qhov chaw nyob siab, nrog ntau txoj kev kwv yees. Xws li IP.SCSI-3.IPI hard disk. HIPPI.ESCON. Ib-byte channel hais kom ua thiab lwm yam. Feem ntau yog qhov projection ntawm SCSI-3, hu ua" FCP".
Qib qis tshaj ntawm kev tswj hwm: Cov kev tswj hwm hauv zos muaj kev sib raug zoo me ntsis nrog cov ntaub ntawv cov ntsiab lus ntawm kev lag luam ecosystem, uas txhais tau hais tias ib qho chaw nres nkoj tsis tshua muaj kev puas tsuaj los ntawm lwm qhov chaw nres nkoj. Nyob rau hauv lem, tus nqi ntawm kev ua hauj lwm nyob rau sab saum toj yog heev txo. Tus nqi qis heev: Kev xaiv ntawm 8B / 10B tus lej thiab ntau qhov ruaj khov thiab txhim khu kev qha kho vajtse ua rau qhov kev ua yuam kev tsawg kawg nkaus, uas ua rau tus nqi ntawm Fiber Channel raws tu qauv me dua thiab cov khoom thauj Fiber Channel kis tau tus nqi siab dua.
Feichang Technology, tus kws tshaj lij tshaj lij ntawm kev sib txuas lus fiber ntau thiab kev daws teeb meem hauv koj lub neej! 20 xyoo ntawm kev paub txog kev ua haujlwm hauv optical fiber optic transceivers, xov tooj fiber ntau optic transceivers, industrial ntau lawm keyboards, fiber optic fiber optic transceivers, raws tu qauv converters thiab lwm yam industrial ntau lawm kev sib txuas lus khoom tsim, tsim thiab kev muag khoom, zoo siab txais tos tuaj thiab sib tham. .
