Tagara tichinzwa nezve fiber opticswitchesuye fiber optic transceivers. Pakati pavo, fiber opticswitchesndeye yakakwirira-kumhanya network yekufambisa relay michina, inonziwo fiber chiteshiswitchesuye SANswitches. Kuenzaniswa neyakajairikaswitches, vanoshandisa tambo dzefiber optic semidziyo yekufambisa. pakati. Zvakanakira zve optical fiber transmission inokurumidza kukurumidza uye yakasimba anti-kupindira kugona. Kune marudzi maviri makuru efiber opticswitches. Imwe ndeye FCchinjainoshandiswa kubatanidza kukuchengetedza. Imwe yacho iEthernetchinja, chiteshi chengarava ndeye optical fiber interface, uye chitarisiko chakafanana neyakajairwa magetsi, asi chimiro chechimiro chakasiyana.
Kune marudzi matatu ekuchinja kwefiber: ekupinda-level switch, workgroup-level fiber switch, uye core-level fiber switch. Saka ngatitangei neyekutanga core-level fiber opticchinja!
1.core-level fiber optic switches
Iyo inonzi core-levelswitches(anonziwo madhairekitori) anowanzo kuwanikwa pakati peSAN hombe, inobatanidza mipendero yakati wandeiswitcheskune mumwe nemumwe kugadzira network yeSAN ine mazana emachiteshi. The corechinjainogona zvakare kushandiswa seyakamirachinjakana kumuchetochinja, asi mabasa ayo anovandudzwa uye chimiro chemukati chinoita kuti ishande zvirinani munzvimbo yekuchengetera yakakosha. Mamwe mabasa epakatichinjazvinosanganisirawo: tsigiro yezvibvumirano kunze kwe 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 izviswitchesndeyekuvaka yakakura yekuvhara network uye nekupa yakakura bandwidth. Iwo akagadzirirwa kufambisa masaini masaini nekukurumidza sezvinobvira pakati pezviteshi zvakawanda nekunonoka kupfupi. Uye zvakare, ma core fiber switch anowanzo shandisa anopisa-anochinja-chinja edunhu mabhodhi akavakirwa pa "blade mhando": cherochinjabhodhi rinoiswa mukhabhineti, 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-redundancyswitcheszvakawandisa, izvo zvinobvisa zvachose mapoinzi ekutadza uye anovimbisa kwenguva refu Uptime. Aya mashandisirwo ekuita redundancy anowanzo kupedzerwa kune yakakwirira-inowanikwa backplanes, magetsi emagetsi, redundant maseketi, uye software kuchengetedza kuwanikwa. Iyi mhando yechinjaine akawanda akavakirwa-mukati logic maseketi kubata kutadza kwehardware mukati mechinja. The coreswitchesmune fiber opticswitcheskupa kuvimbika kwepamusoro uye kusimba kwechiteshi. 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 opticswitches
Fiber optic switches inopa kugona kukanda akawandaswitchesmuMucheka mukuru. Nekubatanidza imwe kana anopfuura madoko maviri ekuchinja, ese madoko akabatana kune iyochinjainogona kuona mufananidzo wakasarudzika wetiweki, uye chero node pajira iri inogona kutaurirana nemamwe ma node. Kuburikidza necascading switch, yakakura, chaiyo, yakagoverwachinjainogona kusimbiswa, uye chinhambwe chainogona kureba chakakura zvikuru. Jira rakagadzirwa neakawanda switch rinotaridzika sejira rinoumbwa nekuchinja kwakasiyana. Zviteshi pane zveseswitchesinogona 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 ndeyekuwana bandwidth yekubatana pakati peswitches. Mwero unoshanda pakati pezviteshi zviviri zvinokanganiswa neiyo inoshanda bandwidth yekubatana pakati peswitches, uye zvingave zvakakosha kushandisa akawanda makubatanidza pakati pekuchinja kuchengetedza inodiwa bandwidth. Workgroup Fiber Channel switches akawanda uye anochinja-chinja. Workgroupswitchesanoshandiswa nenzira 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 paFiber Channelchinja. Nekudaro, kana ukaronga kushandisa zvigadzirwa kubva kune akawanda vatengesi, iwe unofanirwa kuve nechokwadi chekuti zvishandiso zvinodyidzana.
3.yekupinda-chikamuswitches
Iko kushandiswa kwekupinda-level switch mune fiber opticswitchesinonyanya kuiswa mumapoka maduku anoshanda ane 8 kusvika ku16 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 entry-levelswitcheszvakasiyana, asi kazhinji vanozvitenga pamwe chete 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.
