Ama-transceiver e-FC (Fibre Channel)ziyingxenye ebalulekile yengqalasizinda ye-Fibre Channel, futhi ama-transceiver e-Ethernet ahlanganiswe nama-switch e-Ethernet ayinhlanganisela ethandwayo yokufanisa lapho kusetshenziswa i-Ethernet. Ngokusobala, lezi zinhlobo ezimbili zama-transceiver zikhonza izinhlelo zokusebenza ezahlukene, kodwa uyini ngempela umehluko phakathi kwazo? Lesi sihloko sizochaza ngokuningiliziwe ama-transceiver e-Fibre Channel kanye ne-fiber optic.
Buyini ubuchwepheshe be-Fibre Channel?
I-Fibre Channel iyiphrothokholi yenethiwekhi yokudlulisa idatha esheshayo evumela ukudluliselwa okuhlelekile nokungalahleki kwamabhulokhi edatha angavuthiwe. I-Fibre Channel ixhumanisa amakhompyutha ajwayelekile, ama-mainframe, nama-supercomputer namadivayisi okugcina. Iwubuchwepheshe obusekela ngokuyinhloko iphuzu-kuya-ephuzwini (amadivayisi amabili axhunywe ngqo komunye nomunye) futhi ngokuvamile buvame kakhulu endaweni eshintshiwe yendwangu (amadivayisi axhunywe nge-Fibre Channel switch).
I-SAN (Inethiwekhi Yendawo Yokugcina) iyinethiwekhi yangasese esetshenziselwa ukuxhumana kwesitoreji phakathi kwamaseva okusingatha kanye nesitoreji esabiwe, ngokuvamile i-array eyabiwe enikeza isitoreji sedatha esisezingeni lebhulokhi. Ngokuvamile, ama-SAN e-Fibre Channel azofakwa kuzinhlelo zokusebenza ze-low-latency ezifanele kakhulu isitoreji esisekelwe kubhulokhi, njengezizindalwazi ezisetshenziselwa ukucubungula ukuthengiselana okuku-inthanethi okusheshayo (i-OLTP) njengokubhanga, amathikithi aku-inthanethi, kanye nezizindalwazi ezindaweni ezi-virtualized. I-Fibre Channel ngokuvamile isebenza ezintanjeni ze-fiber optic ngaphakathi naphakathi kwezikhungo zedatha, kodwa ingasetshenziswa futhi ngezintambo zethusi.
Iyini i-Fibre Channel Transceiver?
Njengoba sishilo ngenhla, i-Fibre Channel ingadlulisela idatha ye-raw block futhi yakhe ukudluliselwa okungenakulahlekelwa. Ama-transceiver e-Fibre Channel nawo asebenzisa amaphrothokholi okudlulisa idatha ngesivinini esikhulu. Onjiniyela ngokuvamile basebenzisa ama-transceiver e-Fibre Channel ukwakha amaketanga okudlulisa phakathi kwezikhungo zedatha, amaseva, kanye namaswishi.
Ama-transceiver e-Fibre Channel asebenzisa ne-Fibre Channel Protocol (FCP) kwezokuthutha futhi ngokuvamile asetshenziselwa ukuxhumana phakathi kwezinhlelo ze-Fibre Channel naphakathi kwamadivayisi enethiwekhi yokugcina isitoreji se-optical. Ama-transceiver e-Fibre Channel aklanyelwe ngokuyinhloko ukuxhuma amanethiwekhi okugcina e-Fibre Channel ngaphakathi kwezikhungo zedatha.
