Kodi kusiyana pakati pa ma transceivers a fiber optic ndi ma transceivers a Ethernet ndi kotani?

Ma transceiver a FC (Fibre Channel)ndi gawo lofunika kwambiri pa zomangamanga za Fibre Channel, ndipo ma transceiver a Ethernet ophatikizidwa ndi ma switch a Ethernet ndi ophatikizana otchuka poyika Ethernet. Zachidziwikire, mitundu iwiriyi ya ma transceiver imagwira ntchito zosiyanasiyana, koma kodi kusiyana pakati pawo ndi kotani kwenikweni? Nkhaniyi ifotokoza mwatsatanetsatane ma transceiver a Fibre Channel ndi fiber optic.

Kodi ukadaulo wa Fibre Channel ndi chiyani?

Fibre Channel ndi njira yofulumira yosamutsira deta yomwe imalola kusamutsa deta mwadongosolo komanso mosataya nthawi. Fibre Channel imalumikiza makompyuta, ma mainframes, ndi ma supercomputer ndi zipangizo zosungiramo zinthu. Ndi ukadaulo womwe umathandizira makamaka mfundo (zipangizo ziwiri zolumikizidwa mwachindunji) ndipo nthawi zambiri umapezeka kwambiri mu nsalu yosinthidwa (zipangizo zolumikizidwa kudzera mu switch ya Fibre Channel).

SAN (Storage Area Network) ndi netiweki yachinsinsi yomwe imagwiritsidwa ntchito polumikizirana pakati pa ma seva osungira ndi malo osungira omwe amagawidwa, nthawi zambiri imakhala gulu logawana lomwe limapereka kusungira deta ya block-level. Nthawi zambiri, ma Fibre Channel SAN amayikidwa mu mapulogalamu otsika omwe ndi oyenera kwambiri kusungirako deta, monga ma database omwe amagwiritsidwa ntchito pokonza zinthu mwachangu pa intaneti (OLTP) monga kubanki, kutumiza matikiti pa intaneti, ndi ma database m'malo opezeka pa intaneti. Fibre Channel nthawi zambiri imagwira ntchito pa ma fiber optic cables mkati ndi pakati pa malo osungira deta, koma ingagwiritsidwenso ntchito ndi ma cable amkuwa.
Kodi Transceiver ya Fiber Channel ndi chiyani?

Monga tanenera pamwambapa, Fibre Channel imatha kutumiza deta ya raw block ndikupanga kutumiza kosatayika. Ma transceivers a Fibre Channel amagwiritsanso ntchito ma protocol otumizira deta mwachangu kwambiri. Mainjiniya nthawi zambiri amagwiritsa ntchito ma transceivers a Fibre Channel popanga unyolo wotumizira pakati pa malo osungira deta, ma seva, ndi ma switch.

Ma transceiver a Fibre Channel amagwiritsanso ntchito Fibre Channel Protocol (FCP) poyendetsa ndipo nthawi zambiri amagwiritsidwa ntchito polumikiza makina a Fibre Channel ndi zida zosungiramo zinthu zowunikira. Ma transceiver a Fibre Channel makamaka amapangidwa kuti alumikize ma network osungira a Fibre Channel mkati mwa malo osungira deta.
