Pakadali pano, ogwiritsa ntchito ma network ambiri amakampani ndi malo osungira deta amagwiritsa ntchito njira yogawa ma port ya QSFP+ kupita ku SFP+ kuti akweze ma network omwe alipo a 10G kupita ku 40G moyenera komanso mokhazikika kuti akwaniritse kufunikira kwakukulu kwa ma transmission othamanga kwambiri. Njira yogawa ma port ya 40G kupita ku 10G iyi ingagwiritse ntchito bwino zida zomwe zilipo, kuthandiza ogwiritsa ntchito kusunga ndalama, komanso kupangitsa kuti ma network akhale osavuta. Ndiye mungatani kuti mukwaniritse ma transmission a 40G kupita ku 10G? Nkhaniyi igawana njira zitatu zogawa ma port kuti zikuthandizeni kukwaniritsa ma transmission a 40G kupita ku 10G.
Kodi Kuphulika kwa Port ndi chiyani?
Kuphulika kwa maukonde kumathandiza kulumikizana pakati pa zida za netiweki zomwe zili ndi madoko osiyanasiyana othamanga, pomwe zimagwiritsa ntchito bandwidth yonse ya madoko.
Njira yoyambira kugwiritsa ntchito zida za netiweki (maswichi, ma rauta, ndi ma seva) imatsegula njira zatsopano kuti ogwiritsa ntchito netiweki azitsatira liwiro la kufunikira kwa bandwidth. Mwa kuwonjezera ma ports othamanga kwambiri omwe amathandizira kufalikira kwa ma breakout, ogwiritsa ntchito amatha kuwonjezera kuchuluka kwa ma ports a faceplate ndikulola kukweza mpaka ku kuchuluka kwa data pang'onopang'ono.
Zosamala pakugawanitsa 40G ku 10G Ports Breakout
Ma switch ambiri pamsika amathandizira kugawa ma doko. Mutha kuwona ngati chipangizo chanu chikuthandizira kugawa ma doko poyang'ana buku lazinthu za switch kapena kufunsa wogulitsa. Dziwani kuti nthawi zina zapadera, ma switch port sangagawanike. Mwachitsanzo, switch ikagwira ntchito ngati switch ya Leaf, ma doko ena ake sathandizira kugawa ma doko; Ngati switch port imagwira ntchito ngati stack port, doko silingagawanike.
Mukagawa doko la 40 Gbit/s m'madoko a 4 x 10 Gbit/s, onetsetsani kuti doko likugwiritsa ntchito 40 Gbit/s mwachisawawa ndipo palibe ntchito zina za L2/L3 zomwe zimayatsidwa. Dziwani kuti panthawiyi, doko likupitilizabe kugwira ntchito pa 40Gbps mpaka dongosolo litayambiranso. Chifukwa chake, mutagawa doko la 40 Gbit/s m'madoko a 4 x 10 Gbit/s pogwiritsa ntchito lamulo la CLI, yambitsaninso chipangizocho kuti lamulolo liyambe kugwira ntchito.
Ndondomeko ya Ma Cable ya QSFP+ kupita ku SFP+
Pakadali pano, njira zolumikizirana za QSFP+ kupita ku SFP+ zimaphatikizapo izi:
Ndondomeko Yolumikizira Chingwe Cholunjika cha QSFP+ mpaka 4*SFP+ DAC/AOC
Kaya mungasankhe chingwe cha 40G QSFP+ mpaka 4*10G SFP+ DAC copper core high-speed kapena chingwe chogwira ntchito cha 40G QSFP+ mpaka 4*10G SFP+ AOC, kulumikizanako kudzakhala kofanana chifukwa chingwe cha DAC ndi AOC ndi chofanana mu kapangidwe ndi cholinga. Monga momwe chithunzi chili pansipa, mbali imodzi ya chingwe cholunjika cha DAC ndi AOC ndi cholumikizira cha 40G QSFP+, ndipo mbali inayo ndi zolumikizira zinayi zosiyana za 10G SFP+. Cholumikizira cha QSFP+ chimalumikizidwa mwachindunji mu doko la QSFP+ pa switch ndipo chili ndi njira zinayi zofanana, iliyonse yomwe imagwira ntchito pamlingo wofika 10Gbps. Popeza zingwe zothamanga kwambiri za DAC zimagwiritsa ntchito mkuwa ndipo zingwe zogwira ntchito za AOC zimagwiritsa ntchito ulusi, zimathandizanso mtunda wosiyana wa ma transmission. Nthawi zambiri, zingwe zothamanga kwambiri za DAC zimakhala ndi mtunda waufupi wa ma transmission. Uku ndiye kusiyana koonekeratu pakati pa ziwirizi.
Mu kulumikizana kogawanika kwa 40G mpaka 10G, mutha kugwiritsa ntchito chingwe cholumikizira cha 40G QSFP+ mpaka 4*10G SFP+ kuti mulumikizane ndi switch popanda kugula ma module ena optical, zomwe zimapangitsa kuti ndalama zogulira ma network zisamachuluke komanso kuti njira yolumikizira ikhale yosavuta. Komabe, mtunda wotumizira ma network awa ndi wochepa (DAC≤10m, AOC≤100m). Chifukwa chake, chingwe cha Direct DAC kapena AOC ndichoyenera kwambiri kulumikiza kabati kapena makabati awiri oyandikana nawo.
Chingwe Chogwira Ntchito cha 40G QSFP+ mpaka 4*LC Duplex AOC Branch
Chingwe chogwira ntchito cha 40G QSFP+ mpaka 4*LC duplex AOC branch ndi mtundu wapadera wa chingwe chogwira ntchito cha AOC chokhala ndi cholumikizira cha QSFP+ mbali imodzi ndi ma jumper anayi osiyana a LC duplex mbali inayo. Ngati mukufuna kugwiritsa ntchito chingwe chogwira ntchito cha 40G mpaka 10G, muyenera ma module anayi a SFP+ optical, kutanthauza kuti, mawonekedwe a QSFP+ a chingwe chogwira ntchito cha 40G QSFP+ mpaka 4*LC akhoza kulowetsedwa mwachindunji mu doko la 40G la chipangizocho, ndipo mawonekedwe a LC ayenera kulowetsedwa mu gawo logwira ntchito la 10G SFP+ la chipangizocho. Popeza zipangizo zambiri zimagwirizana ndi ma interface a LC, njira yolumikizira iyi ingakwaniritse zosowa za ogwiritsa ntchito ambiri.
MTP-4*LC Branch Optical Fiber Jumper
Monga momwe chithunzichi chikusonyezera, mbali imodzi ya MTP-4*LC branch jumper ndi mawonekedwe a MTP a 8-core olumikizira ku ma module a 40G QSFP+ optical, ndipo mbali inayo ndi ma jumper anayi a LC duplex olumikizira ku ma module anayi a 10G SFP+ optical. Mzere uliwonse umatumiza deta pa liwiro la 10Gbps kuti amalize kutumiza kwa 40G mpaka 10G. Njira yolumikizirayi ndi yoyenera ma network a 40G high-density. Ma jumper a nthambi a MTP-4*LC amatha kuthandizira kutumiza deta kutali poyerekeza ndi zingwe zolumikizira mwachindunji za DAC kapena AOC. Popeza zida zambiri zimagwirizana ndi ma interface a LC, njira yolumikizira ma jumper a nthambi ya MTP-4*LC imatha kupatsa ogwiritsa ntchito njira yolumikizira mawaya yosinthasintha.
Momwe Mungagawire 40G kukhala 4*10G pa intaneti yathuWogulitsa Mapaketi a Pakompyuta a Mylinking™ ML-NPB-3210+ ?
Gwiritsani ntchito chitsanzo: Zindikirani: Kuti muyambitse ntchito yotulukira ya doko 40G pa Command Line, muyenera kuyambitsanso chipangizocho
Kuti mulowe mu CLI configuration mode, lowani mu chipangizochi kudzera mu serial port kapena SSH Telnet. Yambitsani "thandizani---sinthani malo osungira---mawonekedwe ce0---liwiro 40000---yamba mwadzidzi"malamulo motsatizana kuti athandize ntchito yotulukira ya doko la CE0. Pomaliza, yambitsaninso chipangizocho monga momwe mwalangizidwira. Pambuyo poyambitsanso, chipangizocho chingagwiritsidwe ntchito mwachizolowezi.
Chipangizocho chikayambitsidwanso, doko la 40G CE0 lakhala likugawika m'madoko 4 * 10GE CE0.0, CE0.1, CE0.2, ndi CE0.3. Madoko awa amakonzedwa padera ngati madoko ena a 10GE.
Chitsanzo cha pulogalamu: ndikutsegula ntchito yotsegula doko la 40G pamzere wolamula, ndikugawa doko la 40G kukhala madoko anayi a 10G, omwe amatha kukhazikitsidwa padera ngati madoko ena a 10G.
Ubwino ndi Kuipa kwa Breakout
Ubwino wa kuphulika:
● Kuchuluka kwa mphamvu. Mwachitsanzo, switch ya QDD yokhala ndi madoko 36 ingapereke kuchulukitsa kwa mphamvu ya switch ndi madoko olowera pansi a single-lane. Potero kupeza maulumikizidwe ofanana pogwiritsa ntchito ma switch ochepa.
● Kufikira ma interfaces otsika liwiro. Mwachitsanzo, transceiver ya QSFP-4X10G-LR-S imalola switch yokhala ndi ma doko a QSFP okha kuti ilumikize ma interfaces a 4x 10G LR pa doko lililonse.
● Kusunga Ndalama. Chifukwa cha kufunikira kochepa kwa zida wamba kuphatikizapo chassis, makadi, ogulitsa magetsi, mafani, …
Zoyipa za kuphulika:
● Njira yosinthira zinthu yovuta kwambiri. Pamene imodzi mwa madoko omwe ali pa transceiver yotseguka, AOC kapena DAC, yawonongeka, imafunika kusintha transceiver yonse kapena chingwe.
● Sizosinthika mosavuta. Mu ma switch okhala ndi ma single-lane downlinks, doko lililonse limakonzedwa payekhapayekha. Mwachitsanzo, doko lililonse likhoza kukhala 10G, 25G, kapena 50G ndipo likhoza kulandira mtundu uliwonse wa transceiver, AOC kapena DAC. Doko la QSFP lokha lomwe lili mu breakout mode limafuna njira yogwirira ntchito ndi gulu, pomwe ma interfaces onse a transceiver kapena chingwe ndi amtundu womwewo.
