Keeb kwm ntawm Fiber Channel Technology
Kev loj hlob tawg ntawm cov ntaub ntawv hauv cov ntaub ntawv hnub nyoog tau muab lub sijhawm zoo rau kev txhim kho cov cuab yeej siv cia. Tam sim no cov neeg saib xyuas cov ntaub ntawv muaj kev txhawj xeeb ntau ntxiv txog yuav khaws, tswj thiab siv cov ntaub ntawv li cas kom nyab xeeb. Yog li ntawd, tib neeg tsis tsuas yog muaj kev xav tau siab dua thiab siab dua rau kev cia khoom muaj peev xwm thiab kev ua tau zoo, tab sis kuj tau muab cov kev xav tau rau kev cia cov tshuab nrog kev ua haujlwm siab, muaj kev ntseeg siab, thiab kev sib kis ntev -. Fiber Channel (Fiber Channel) thev naus laus zis tau yug los nyob rau hauv kev tsav ntawm qhov kev thov no.
At present, in the design of storage systems, any business system that involves operating on a large relational database and reading massive data generally tends to adopt a storage area network (Storage Area Networks) architecture. A storage area network (hereinafter referred to as "SAN") is a network system based on a networked I/O storage protocol that enables "any to any" connection and communication between servers and storage devices. The development of SAN has driven the development of Fibre Channel technology, and the development of Fibre Channel architecture has paved the way for the technical conception of SAN.
Fiber Channel thev naus laus zis yog cov txheej txheem tsim raws li Fiber Channel, uas tau tsim nyob rau xyoo 1989, thiab cov qauv ANSI raug tsim nyob rau lub Kaum Hlis 1994. Ntxiv rau qhov kho qhov muag cable, qhov nruab nrab ntawm Fiber Channel technology muaj lwm yam kis tau tus mob xws li tooj liab cable. , tab sis feem ntau nws yog hu ua optical channel thoob ntiaj teb. Fiber Channel thev naus laus zis tuaj yeem tsim kho sai thiab dav siv (xav txog qhov tshwm sim ntawm ntau lub tshuab SAN siv FC thev naus laus zis), tsis yog vim Fiber Channel muaj bandwidth ntau dua, kev sib txuas ntev dua, kev ruaj ntseg zoo dua thiab ua kom muaj zog, Qhov tseem ceeb dua, Fiber Channel thev naus laus zis sib xyaw ua ke qhov zoo ntawm channel technology thiab network technology. Siv Fiber Channel network tuaj yeem tsim qhov chaw cia khoom network (SAN) uas txawv ntawm qhov zoo -paub hauv cheeb tsam network (LAN) lossis txawm tias lub nroog cheeb tsam network (MAN). SAN tsis yog ib yam khoom, tab sis yog ib txoj hauv kev ntawm kev teeb tsa lub network cia. Nws lub tswv yim tseem ceeb yog hloov cov ntaub ntawv pauv ntawm cov kev sib txuas ib txwm siv rau SAN feem ntau yog tsim los ntawm cov khoom siv cia thiab cov chaw khaws ntaub ntawv. Nrog kev pab los ntawm Fiber Channel thev naus laus zis, SAN txhawb nqa ntev - kev sib txuas lus nyob deb, thiab cais cov ntaub ntawv khaws cia los ntawm cov kev pabcuam hauv daim ntawv thov, kom cov khoom siv khaws cia tuaj yeem dhau los ua cov peev txheej sib koom uas txhua lub servers txuas nrog SAN tuaj yeem nkag tau ntawm kev kub ceev, kev ruaj ntseg , thiab kev ntseeg tau. Cov khoom siv khaws cia, xws li disk arrays thiab cov tsev qiv ntawv kab xev, ua haujlwm ua ke yam tsis tau mus los ntawm cov neeg siv khoom nruab nrab siab. SAN daws qhov teeb meem uas ib zaug muaj ntau cov ntaub ntawv nkag tau tshwm sim hauv ib txwm LAN, kev ua haujlwm hauv network yuav raug txo kom tsawg, yog li cov ntaub ntawv nkag, thaub qab thiab rov qab yuav tsis cuam tshuam rau kev ua haujlwm ntawm LAN, hauv paus lav qhov kev pabcuam zoo ntawm daim ntawv thov. system, thiab tuaj yeem txo qis kev ua haujlwm hauv network. txo cov nqi tswj hwm
