Pakalipano, ogwiritsa ntchito mabizinesi ambiri ndi data center amagwiritsa ntchito QSFP + ku SFP + port breakout splitting scheme kuti apititse patsogolo maukonde omwe alipo a 10G ku 40G network moyenera komanso mokhazikika kuti akwaniritse kufunikira kowonjezereka kwa kufalikira kwachangu. Dongosolo logawanitsa la 40G mpaka 10G litha kugwiritsa ntchito mokwanira zida zomwe zilipo kale, kuthandizira ogwiritsa ntchito kusunga ndalama, ndikuchepetsa kasinthidwe ka maukonde. Ndiye mungakwaniritse bwanji kufalitsa kwa 40G mpaka 10G? Nkhaniyi igawana njira zitatu zogawanitsa kuti zikuthandizeni kukwaniritsa kutumiza kwa 40G mpaka 10G.
Kodi Port Breakout ndi chiyani?
Ma breakouts amathandizira kulumikizana pakati pa zida zama netiweki zokhala ndi ma doko osiyanasiyana othamanga, pomwe amagwiritsa ntchito bandwidth yadoko.
Mawonekedwe a breakout pazida za netiweki (ma switch, ma routers, ndi ma seva) amatsegula njira zatsopano za ogwiritsa ntchito ma network kuti aziyenderana ndi liwiro la bandwidth. Powonjezera madoko othamanga kwambiri omwe amathandizira kuphulika, ogwiritsa ntchito amatha kukulitsa kachulukidwe ka madoko a faceplate ndikupangitsa kuti ziwonjezeke kumitengo yayikulu kwambiri.
Kusamala pakugawa 40G ku 10G Ports Breakout
Ambiri masiwichi mu msika thandizo doko kugawanika. Mutha kuyang'ana ngati chipangizo chanu chimathandizira kugawanika kwa doko poyang'ana buku lakusintha kwazinthu kapena kufunsa wogulitsa. Dziwani kuti nthawi zina zapadera, ma doko osinthira sangathe kugawidwa. Mwachitsanzo, pamene chosinthira chimagwira ntchito ngati Leaf switch, ena mwa madoko ake samathandizira kugawanika kwa doko; Ngati doko losinthira likugwira ntchito ngati doko, doko silingagawidwe.
Mukagawa doko la 40 Gbit/s kukhala madoko a 4 x 10 Gbit/s, onetsetsani kuti doko likuyenda 40 Gbit/s mwachisawawa ndipo palibe ntchito zina za L2/L3 zomwe zayatsidwa. Zindikirani kuti panthawiyi, doko likupitiriza kuthamanga pa 40Gbps mpaka dongosolo liyambiranso. Chifukwa chake, mutatha kugawa doko la 40 Gbit/s kukhala madoko a 4 x 10 Gbit/s pogwiritsa ntchito lamulo la CLI, yambitsaninso chipangizocho kuti lamulo ligwire ntchito.
QSFP+ kupita ku SFP+ Cabling Scheme
Pakadali pano, njira zolumikizirana za QSFP+ mpaka SFP+ makamaka zikuphatikiza izi:
QSFP+ mpaka 4* SFP+ DAC/AOC Direct Cable Connection Scheme
Kaya mumasankha 40G QSFP + ku 4 * 10G SFP + DAC copper core high-speed chingwe kapena 40G QSFP + mpaka 4 * 10G SFP + AOC chingwe chogwira ntchito, kugwirizana kudzakhala kofanana chifukwa chingwe cha DAC ndi AOC ndizofanana ndi mapangidwe ndi cholinga. Monga momwe tawonetsera m'chithunzichi, mapeto amodzi a DAC ndi AOC chingwe cholunjika ndi 40G QSFP + cholumikizira, ndipo mapeto ena ndi anayi osiyana 10G SFP + zolumikizira. Cholumikizira cha QSFP + chimalumikiza mwachindunji padoko la QSFP + posinthira ndipo chimakhala ndi njira zinayi zofananira, iliyonse yomwe imagwira ntchito pamitengo mpaka 10Gbps. Popeza zingwe zothamanga kwambiri za DAC zimagwiritsa ntchito zingwe zamkuwa ndi AOC zogwira ntchito zimagwiritsa ntchito fiber, zimathandiziranso mtunda wosiyanasiyana. Nthawi zambiri, zingwe zothamanga kwambiri za DAC zimakhala ndi mtunda waufupi wotumizira. Uku ndiko kusiyana koonekeratu pakati pa ziwirizi.
Mu 40G ku 10G kugwirizana kugawanika, mungagwiritse ntchito 40G QSFP + ku 4 * 10G SFP + chingwe cholumikizira mwachindunji kuti mugwirizane ndi kusinthana popanda kugula ma modules owonjezera opangira, kusunga ndalama za intaneti ndi kuphweka njira yolumikizira. Komabe, mtunda wotumizira wa kugwirizana uku ndi wochepa (DAC≤10m, AOC≤100m). Chifukwa chake, chingwe cholunjika cha DAC kapena AOC ndichoyenera kulumikiza kabati kapena makabati awiri oyandikana nawo.
40G QSFP+ mpaka 4 * LC Duplex AOC Branch Active Cable
The 40G QSFP + ku 4 * LC duplex AOC nthambi yogwira chingwe ndi mtundu wapadera wa chingwe chogwira ntchito cha AOC chokhala ndi cholumikizira cha QSFP + kumbali imodzi ndi ma jumpers anayi osiyana a LC duplex kumbali inayo. Ngati mukufuna kugwiritsa ntchito chingwe chogwira ntchito cha 40G mpaka 10G, mukufunikira ma module anayi a SFP + optical, ndiko kuti, mawonekedwe a QSFP + a 40G QSFP + mpaka 4 * LC duplex yogwira chingwe akhoza kulowetsedwa mwachindunji mu doko la 40G la chipangizocho, ndipo Mawonekedwe a LC ayenera kuyikidwa mu 10G SFP + optical module ya chipangizocho. Popeza zida zambiri zimagwirizana ndi LC zolumikizira, mawonekedwe olumikizirawa amatha kukwaniritsa zosowa za ogwiritsa ntchito ambiri.
MTP-4* LC Nthambi Optical Fiber Jumper
Monga momwe tawonetsera mu chithunzi chotsatirachi, mapeto amodzi a MTP-4 * LC jumper ya nthambi ndi mawonekedwe a 8-core MTP kuti agwirizane ndi 40G QSFP + optical modules, ndipo mapeto ena ndi ma duplex anayi a LC jumpers kuti agwirizane ndi ma modules anayi a 10G SFP + optical. . Mzere uliwonse umatumiza deta pa mlingo wa 10Gbps kuti amalize kutumiza kwa 40G ku 10G. Njira yolumikizira iyi ndi yoyenera kwa ma network a 40G apamwamba kwambiri. Ma jumper a nthambi a MTP-4 * LC amatha kuthandizira kutumiza kwa data mtunda wautali poyerekeza ndi zingwe zolumikizira mwachindunji za DAC kapena AOC. Popeza kuti zipangizo zambiri zimagwirizana ndi LC interfaces, MTP-4 * LC nthambi jumper connection scheme ikhoza kupatsa ogwiritsa ntchito njira yowongoka yowongoka.
Momwe Mungatulutsire 40G kukhala 4 * 10G pa athuMylinking™ Network Packet Broker ML-NPB-3210+ ?
Gwiritsani ntchito chitsanzo: Zindikirani: Kuti mutsegule doko 40G pa Command Line, muyenera kuyambitsanso chipangizocho
Kuti mulowetse mawonekedwe a CLI, lowani ku chipangizocho kudzera pa doko la serial kapena SSH Telnet. Thamangani"athe---konza terminal---mawonekedwe ce0---liwiro 40000---yamba mwadzidzi” amalamula motsatizana kuti atsegule CE0 port breakout. Pomaliza, yambitsaninso chipangizocho monga momwe mwafunira. Pambuyo poyambitsanso, chipangizocho chingagwiritsidwe ntchito bwino.
Chipangizochi chikayambiranso, doko la 40G CE0 lakhala likuphulika mu 4 * 10GE madoko CE0.0, CE0.1, CE0.2, ndi CE0.3. Madoko awa amapangidwa padera ngati madoko ena a 10GE.
Pulogalamu yachitsanzo: ndikupangitsa kuti pakhale doko la 40G pamzere wolamula, ndikutulutsa doko la 40G kukhala madoko anayi a 10G, omwe amatha kukhazikitsidwa padera ngati madoko ena a 10G.
Ubwino wa Breakout ndi Zoyipa
Ubwino wa breakout:
● Kuchulukana kwambiri. Mwachitsanzo, 36-port QDD breakout switch imatha kupereka katatu kachulukidwe ka switch yokhala ndi ma doko anjira imodzi. Potero kukwaniritsa nambala yolumikizirana yofanana pogwiritsa ntchito ma switch ochepa.
● Kufikira kumalo othamanga kwambiri. Mwachitsanzo, transceiver ya QSFP-4X10G-LR-S imathandizira kusinthana ndi madoko a QSFP okha kuti alumikizane ndi 4x 10G LR padoko.
● Kusunga Ndalama. Chifukwa chosowa zida wamba kuphatikiza chassis, makhadi, ogulitsa magetsi, mafani, ...
Kuipa kwa breakout:
● Njira yosavuta yosinthira. Pamene imodzi mwa madoko pa transceiver yophulika, AOC kapena DAC, ikafika poipa, imafunika kusinthidwa kwa transceiver kapena chingwe chonse.
● Osati monga makonda. Mu masinthidwe okhala ndi njira imodzi yochepetsera, doko lililonse limakonzedwa payekhapayekha. Mwachitsanzo, doko lapadera likhoza kukhala 10G, 25G, kapena 50G ndipo likhoza kuvomereza mtundu uliwonse wa transceiver, AOC kapena DAC. Doko lokhalo la QSFP pamachitidwe oduka limafunikira njira yanzeru yamagulu, pomwe mawonekedwe onse a transceiver kapena chingwe ndi mtundu womwewo.
