Kune marudzi matatu ekuchinja kwefiber: ekupinda-level switch, workgroup-level fiber switch, uye core-level fiber switch.Saka ngatitangei neyekutanga core-level fiber optic switch!
1.core-level fiber optic switches
Iwo anonzi ma-core-level switch (anonziwo madhairekitori) anowanzo kuwanikwa pakati peSAN hombe, achibatanidza machinjiko akati wandei kune mumwe nemumwe kugadzira network yeSAN ine mazana emachiteshi.Iyo yepakati switch inogona zvakare kushandiswa seyakamira yakamira switch kana edge switch, asi yakawedzera mabasa uye chimiro chemukati chinoita kuti ishande zvirinani munzvimbo yekuchengetera yakakosha.Mamwe mabasa eiyo core switch anosanganisirawo: kutsigirwa kwezvibvumirano zvisiri optical fiber (seInfiniBand), kutsigirwa kwe2Gbps Fiber Channel, uye advanced optical services (semuenzaniso: chengetedzo, trunk uye furemu kusefa, nezvimwewo).Core-level fiber optic switches inowanzopa akawanda madoko, kubva pa64 ports kusvika 128 ports nezvimwe.Inoshandisa yakafararira yemukati yekubatanidza kufambisa data mafuremu ane yakanyanya bandwidth.Chinangwa chekushandisa ma switch aya ndechekuvaka yakakura yekuvhara network uye nekupa yakakura bandwidth.Iwo akagadzirirwa kufambisa masaini masaini nekukurumidza sezvinobvira pakati pezviteshi zvakawanda nekunonoka kupfupi.Mukuwedzera, core fiber switches inowanzoshandisa inopisa-swappable circuit boards inobva pa "blade type": chero bedzi bhodhi rekushandura rakaiswa mubhanhire, mabasa matsva anogona kuwedzerwa, uye kugadziriswa kwepaIndaneti kunogonawo kuitwa.Inoda kuwedzerwa.Mazhinji epakati-level switch haatsigire arbitrated loops kana mamwe akabatana zvakananga loop zvishandiso.Ivo chete vane hanya nezve core switching kugona.Nemhaka yokuti kuwanikwa ndiko kunonyanya kukosha munharaunda yose, vanhu vanoda kushandisa mari yakawanda pakugadzirisa basa.Zvose zvikamu zve-high-redundancy switches hazvina basa, izvo zvinobvisa zvachose pfungwa imwe chete yekukundikana uye inovimbisa kwenguva refu Uptime.Aya mashandisirwo ekuita redundancy anowanzo kupedzerwa kune yakakwirira-inowanikwa backplanes, magetsi emagetsi, redundant maseketi, uye software kuchengetedza kuwanikwa.Iyi mhando yekuchinja ine akawanda akavakirwa-mukati logic maseketi kubata kutadza kwehardware mukati meiyo switch.Iwo epakati switch mune fiber optic switch inopa yakanyanya kuvimbika uye density yechiteshi.Munzvimbo yedata ine huwandu hukuru hweFiber Channel zvivakwa, zvigadzirwa zvakadaro zvinenge zvisingatambudzike, zvepakati pekuchengetedza switch.Naizvozvo, kune mazhinji-anowanikwa-akawanda network, iwe unofanirwa kusarudza mbiri-chaneti network yakagadzirwa nepakati fiber switch.
2.workgroup-level fiber optic switches
Fiber optic switches inopa kugona kukanda ma switch akawanda mumucheka wakakura.Nekubatanidza imwe kana kupfuura zviteshi zvema switch maviri, zviteshi zvese zvakabatana kune switch zvinogona kuona yakasarudzika mufananidzo wetiweki, uye chero node pamucheka uyu inogona kutaurirana nemamwe ma node.Kuburikidza necascading switch, yakakura, chaiyo, yakagoverwa switch inogona kugadzwa, uye chinhambwe chainokwanisa kureba chakakura kwazvo.Jira rakagadzirwa neakawanda switch rinotaridzika sejira rinoumbwa nekuchinja kwakasiyana.Zviteshi pane ese ma switch anogona kutariswa uye kuwanikwa semamwe ese madoko pajira sekuwana ma switch emuno.Iyo yakabatana zita sevha uye manejimendi sevhisi inobvumira kutarisa uye kugadzirisa ese Fabric ruzivo kuburikidza neimwe interface.Chinhu chakakosha pakugadzira jira rakagoverwa nderokuwana bandwidth yekubatanidza pakati pekuchinja.Chiyero chinoshanda pakati pezvikepe zviviri zvezvikepe zvinokanganiswa neiyo inoshanda bandwidth yekubatanidza pakati pema switch, uye zvingave zvakafanira kushandisa akawanda kubatanidza pakati pekuchinja kuti uchengetedze inodiwa bandwidth.Workgroup Fiber Channel switches akawanda uye anochinja-chinja.Shanduko dzeboka rebasa dzinoshandiswa munzira dzakawanda, asi nzvimbo inonyanya kushandiswa idiki SAN.Shanduko dzakadaro dzinogona kubatanidzwa pamwechete kuburikidza nemitsara yekubatanidza pakati pema switch kuti ipe mamwe madoko.Mitsetse yekubatanidza pakati pekuchinja inogona kugadzirwa pane chero chiteshi pane Fiber Channel switch.Nekudaro, kana ukaronga kushandisa zvigadzirwa kubva kune akawanda vatengesi, iwe unofanirwa kuve nechokwadi chekuti zvishandiso zvinodyidzana.
3.entry-level switches
Iko kushandiswa kwekupinda-level switch mufiber optic switches kunonyanya kutariswa mumapoka madiki anoshanda ane 8 kusvika 16 ports.Inokodzera zviitiko nemitengo yakaderera uye zvishoma zvinoda kuwedzera uye manejimendi.Ivo vanowanzo shandiswa kutsiva hubs, iyo inogona kupa yakakwira bandwidth uye inopa hukama hwakavimbika kupfuura hubs.Vanhu kazhinji havatengi ekupinda-level switch zvakasiyana, asi kazhinji vanoatenga pamwe nemamwe mazinga ekuchinja kuti vagadzire yakakwana yekuchengetedza mhinduro.Entry-level fiber optic switches inopa hushoma nhanho yechiteshi cascading kugona.Kana vashandisi vakashandisa zvigadziriso zvakaderera zvakadaro vega, vanogona kusangana nematambudziko ekugadzirisa.
