Sivame ukuzwa ngokushintshwa kwe-fiber optic kanye nama-transceivers e-fiber optic.Phakathi kwazo, amaswishi e-fiber optic kukhona okokudluliswa kwenethiwekhi okunesivinini esikhulu, okubuye kubizwe ngokuthi amaswishi e-fibre channel namaswishi e-SAN.Uma kuqhathaniswa nokushintsha okujwayelekile, basebenzisa izintambo ze-fiber optic njengemishini yokudlulisela.okuphakathi.Izinzuzo zokudluliswa kwe-fiber optical isivinini esisheshayo nekhono eliqinile lokulwa nokuphazamiseka.Kunezinhlobo ezimbili eziyinhloko zokushintshwa kwe-fiber optic.Enye yiswishi ye-FC esetshenziselwa ukuxhuma kusitoreji.Okunye ukushintshwa kwe-Ethernet, ichweba liwukuxhunywa kwefiber optical, futhi ukubukeka kuyafana nesixhumi esibonakalayo sikagesi esivamile, kodwa uhlobo lwesixhumi esibonakalayo luhlukile.
Kunezinhlobo ezintathu zokushintshwa kwefayibha: ukushintsha kwezinga lokungena, ukushintshwa kwefayibha yeleveli yeqembu lomsebenzi, kanye nokushintshwa kwefayibha yezinga eliyinhloko.Ngakho-ke ake siqale ngeswishi yokuqala ye-fiber optic yezinga eliyinhloko!
1.amaswishi e-fiber optic yezinga eliyisisekelo
Okubizwa ngokuthi ama-core-level switches (aphinde abizwe ngokuthi abaqondisi) ngokuvamile atholakala phakathi nendawo ye-SAN enkulu, exhuma amaswishi ambalwa komunye nomunye ukuze akhe inethiwekhi ye-SAN enamakhulu ezichweba.Iswishi eyinhloko ingasetshenziswa futhi njengokushintsha okuzimele noma ukushintsha konqenqema, kodwa imisebenzi yayo ethuthukisiwe kanye nesakhiwo sangaphakathi kuyenza isebenze kangcono endaweni yokugcina okuyisisekelo.Eminye imisebenzi ye-switch core iphinde ihlanganise: ukusekelwa kwezivumelwano ngaphandle kwe-fiber optical (njenge-InfiniBand), ukusekelwa kwe-2Gbps Fiber Channel, nezinsizakalo ze-optical ezithuthukisiwe (isibonelo: ukuphepha, ukuhlunga kwe-trunk kanye nohlaka, njll.).Amaswishi e-fiber optic yeleveli eyinhloko ngokuvamile ahlinzeka ngezimbobo eziningi, kusukela ezimbobeni ezingu-64 kuye kwezingu-128 nokuningi.Isebenzisa ukuxhumana okubanzi kakhulu kwangaphakathi ukuhambisa amafreyimu edatha anomkhawulokudonsa omkhulu.Inhloso yokusebenzisa lezi zinguquko ukwakha inethiwekhi enkulu yokuhlanganisa nokuhlinzeka ngomkhawulokudonsa omkhulu.Zenzelwe ukuhambisa amasiginali wozimele ngokushesha okukhulu phakathi kwezimbobo eziningi ezinokulibaziseka okufushane kakhulu.Ngaphezu kwalokho, ukushintshwa kwe-core fiber kuvame ukusebenzisa amabhodi wesifunda ashisayo ashintshwayo asekelwe "kuhlobo lwe-blade": inqobo nje uma ibhodi lokushintsha lifakwe ekhabhinethi, imisebenzi emisha ingangezwa, nokugcinwa kwe-inthanethi nakho kungenziwa.Idinga ukunwetshwa.Amaswishi amaningi ezinga eliyinhloko awasekeli amalophu ane-arbitrated noma amanye amadivayisi axhumeke ngokuqondile.Bakhathalela kuphela amakhono ayisisekelo okushintsha.Ngenxa yokuthi ukutholakala kubaluleke kakhulu endaweni yonke, abantu bazimisele ukuchitha imali eningi ekuqedeni umsebenzi.Zonke izingxenye zokushintshwa kwe-high-redundancy switch azidingeki, okuqeda ngokuphelele iphuzu elilodwa lokuhluleka futhi kuqinisekisa isikhathi eside kakhulu se-Uptime.Lezi zindleko zokuphinda zisetshenziswe ngokuvamile zisetshenziselwa izindiza ezibuyela emuva ezitholakala kakhulu, izinsiza zikagesi, amasekhethi angasasebenzi, kanye nesofthiwe ukuze kugcinwe ukutholakala.Lolu hlobo lokushintsha lunamasekhethi amaningi anengqondo akhelwe ngaphakathi ukuze abambe ukwehluleka kwehadiwe ngaphakathi kweswishi.Amaswishi ayinhloko kumaswishi e-fiber optic ahlinzeka ngokuthembeka okuphezulu nokuminyana kwembobo.Esikhungweni sedatha esinenani elikhulu lengqalasizinda ye-Fiber Channel, imikhiqizo enjalo cishe ayinabungozi, amaswishi esitoreji aphakathi nendawo.Ngakho-ke, kumanethiwekhi amaningi atholakala kakhulu, kufanele ukhethe inethiwekhi eneziteshi ezimbili eyakhiwe amaswishi e-fiber eyinhloko.
2.i-workgroup-level fibre optic switches
Amaswishi e-fiber optic anikeza amandla okushintsha amaswishi amaningi enze Indwangu yezinga elikhulu.Ngokuxhuma imbobo eyodwa noma amaningi amaswishi amabili, zonke izimbobo ezixhunywe ekushintsheni zingabona isithombe esiyingqayizivele senethiwekhi, futhi noma iyiphi i-node kule ndwangu ingaxhumana namanye ama-node.Ngokushintsha kwe-cascading, inkinobho enkulu, ebonakalayo, esabalalisiwe ingasungulwa, futhi ibanga elingalithatha likhulu kakhulu.Indwangu eyakhiwe ngokushintshashintsha okuningi ibonakala njengendwangu ehlanganiswe nokushintshashintsha okuhlukene.Izimbobo kuwo wonke amaswishi zingabukwa futhi zifinyelelwe njengazo zonke ezinye izimbobo zendwangu njengokufinyelela kumaswishi asendaweni.Iseva yegama elihlanganisiwe kanye nensizakalo yokuphatha ivumela ukubuka nokulungisa yonke imininingwane Yendwangu ngokusebenzisa isixhumi esibonakalayo esisodwa.Isici esibalulekile ekudaleni indwangu esabalalisiwe ukuthola umkhawulokudonsa wokuxhuma phakathi kokushintsha.Izinga elisebenzayo phakathi kwanoma yiziphi izimbobo ezimbili lithintwa umkhawulokudonsa osebenzayo wokuxhuma phakathi kwamaswishi, futhi kungase kudingeke ukuthi kusetshenziswe ukuxhumana okuningi phakathi kwamaswishi ukuze kugcinwe umkhawulokudonsa odingekayo.Amaswishi e-Workgroup Fiber Channel maningi futhi ayashintshashintsha.Amaswishi eqembu lomsebenzi asetshenziswa ngezindlela eziningi, kodwa indawo esetshenziswa kakhulu yi-SAN encane.Ukushintsha okunjalo kungaxhunywa ndawonye ngemigqa yokuxhuma phakathi kwamaswishi ukuze kuhlinzekwe ngezimbobo ezengeziwe.Imigqa yokuxhumana phakathi kwamaswishi ingadalwa kunoma iyiphi imbobo kuswishi ye-Fiber Channel.Kodwa-ke, uma uhlela ukusebenzisa imikhiqizo evela kubathengisi abaningi, kufanele uqinisekise ukuthi amadivayisi ayasebenzisana.
3.ukushintsha kwezinga lokungena
Ukusetshenziswa koshintsho lwezinga lokungena ekushintsheni kwe-fiber optic kugxilwe kakhulu emaqenjini amancane asebenzayo anamachweba angu-8 kuya kwangu-16.Ilungele izikhathi ezinamanani aphansi nesidingo esincane sokunwetshwa nokuphathwa.Avame ukusetshenziselwa ukufaka esikhundleni samahabhu, anganikeza umkhawulokudonsa ophezulu futhi anikeze ukuxhumana okuthembekile kunamahabhu.Ngokuvamile abantu abawathengi amaswishi ezinga lokungena ngokuhlukana, kodwa ngokuvamile bawathenga kanye namanye amaleveli okushintsha ukuze bakhe isixazululo esiphelele sokulondoloza.Amaswishi e-fiber optic yeleveli yokungena ahlinzeka ngezinga elilinganiselwe lamakhono okukhipha imbobo.Uma abasebenzisi basebenzisa amadivayisi anesimo esiphansi kuphela, bangase bahlangabezane nezinkinga ezithile zokuphatha.
