Parizvino, vazhinji vebhizinesi network nevashandisi ve data data vanotora QSFP + kuSFP + port breakout splitting scheme yekusimudzira iripo 10G network kune 40G network zvinobudirira uye zvakatsiga kuti isangane nekuwedzera kudiwa kwepamusoro-kukurumidza kutapurirana. Iyi 40G kusvika ku10G port splitting scheme inogona kushandisa zvizere zvishandiso zviripo zvetiweki, kubatsira vashandisi kuchengetedza mutengo, uye kurerutsa network kumisikidza. Saka sei kuwana 40G kusvika 10G kutapurirana? Ichi chinyorwa chichagovera zvirongwa zvitatu zvekuparadzanisa kuti zvikubatsire kuwana 40G kusvika ku10G kutapurirana.
Chii chinonzi Port Breakout?
Breakouts inogonesa kubatana pakati petiweki zvishandiso zvine akasiyana ekumhanya madoko, nepo uchishandisa zvizere port bandwidth.
Breakout mode panetiweki zvishandiso (switch, routers, uye maseva) inovhura nzira nyowani dzevashandisi venetiweki kuti vaenderane nekumhanya kwekudiwa kwebandwidth. Nekuwedzera yakakwirira-kumhanya madoko anotsigira kubuda, vashandisi vanogona kuwedzera faceplate port density uye kugonesa kukwidziridza kune yakakwirira data data nekuwedzera.
Chengetedzo yekuparadzanisa 40G kusvika 10G Ports Breakout
Mazhinji anochinja mumusika wekutsigira chiteshi kupatsanura. Iwe unogona kutarisa kuti mudziyo wako unotsigira kupatsanurwa kwechiteshi nekutaura kune switch yechigadzirwa bhuku kana kubvunza mutengesi. Ziva kuti mune zvimwe zviitiko zvakakosha, switch ports haigone kupatsanurwa. Semuyenzaniso, kana chinja anoita seLeaf chinja, zvimwe zviteshi zvayo hazvitsigiri kupatsanurwa kwechiteshi; Kana switch port ichishanda se stack port, port haigone kupatsanurwa.
Kana uchitsemura 40 Gbit/s chiteshi kuita 4 x 10 Gbit/s zviteshi, ita shuwa kuti chiteshi chinomhanya makumi mana Gbit/s nekukasira uye hapana mamwe mabasa eL2/L3 anogoneswa. Ziva kuti panguva iyi, chiteshi chinoramba chichimhanya pa40Gbps kudzamara sisitimu yatangazve. Naizvozvo, mushure mekupatsanura 40 Gbit/s chiteshi kuita 4 x 10 Gbit/s zviteshi uchishandisa CLI kuraira, tangazve chishandiso kuita kuti murairo ushande.
QSFP+ kune SFP+ Cabling Scheme
Parizvino, QSFP+ kune SFP+ zvirongwa zvekubatanidza zvinonyanya zvinosanganisira zvinotevera:
QSFP+ kusvika 4* SFP+ DAC/AOC Yakananga Cable Yekubatanidza Scheme
Pasinei nokuti unosarudza 40G QSFP + kusvika 4 * 10G SFP + DAC copper core high-speed cable kana 40G QSFP + kusvika 4 * 10G SFP + AOC inoshanda cable, kubatana kuchave kwakafanana nokuti DAC neAOC cable yakafanana mukugadzira uye chinangwa. Sezvinoratidzwa mumufananidzo uri pasi apa, imwe mugumo weDAC neAOC yakananga tambo ndeye 40G QSFP + connector, uye imwe magumo mana akasiyana 10G SFP + connectors. Iyo QSFP + connector plugs yakananga muchiteshi cheQSFP + pane switch uye ine ina inofananidzwa bidirectional chiteshi, imwe neimwe inoshanda pamitengo inosvika ku10Gbps. Sezvo tambo dzeDAC dzinomhanya-mhanya dzichishandisa tambo dzemhangura neAOC dzinoshanda dzinoshandisa fiber, dzinotsigirawo madaro akasiyana ekutapurirana. Kazhinji, tambo dzeDAC dzepamusoro-soro dzine mapfupi ekufambisa madaro. Uyu ndiwo musiyano unonyanya kuoneka pakati pezviviri izvi.
Mune 40G kusvika 10G kupatsanurwa kwekubatanidza, unogona kushandisa 40G QSFP + kusvika 4 * 10G SFP + tambo yekubatanidza yakananga kuti ubatanidze kune chinja pasina kutenga mamwe optical modules, kuchengetedza mari ye network uye kurerutsa nzira yekubatanidza. Zvisinei, kureba kwekufambisa kwekubatanidza uku kunogumira (DAC≤10m, AOC≤100m). Naizvozvo, yakananga DAC kana AOC tambo inonyanya kukodzera kubatanidza kabati kana maviri ari padyo makabati.
40G QSFP+ kusvika 4 * LC Duplex AOC Branch Active Cable
Iyo 40G QSFP + kusvika ku4 * LC duplex AOC bazi rinoshanda tambo imhando yakakosha yeAOC inoshanda tambo ine QSFP + yekubatanidza kune imwe mugumo uye ina dzakasiyana LC duplex jumpers pane imwe. Kana ukaronga kushandisa 40G kusvika 10G tambo inoshanda, unoda ina SFP + optical modules, kureva, QSFP + interface ye40G QSFP + kusvika 4 * LC duplex inoshanda cable inogona kuiswa zvakananga muchiteshi che 40G chechigadzirwa, uye LC interface inofanira kuiswa mune inoenderana 10G SFP + optical module yechigadzirwa. Sezvo maturusi mazhinji achienderana neLC interfaces, iyi nzira yekubatanidza inogona kuzadzisa zvirinani zvinodiwa nevazhinji vashandisi.
MTP-4 * LC Bazi Optical Fiber Jumper
Sezvinoratidzwa mumufananidzo unotevera, imwe mugumo weMTP-4 * LC jumper yebazi ndeye 8-core MTP interface yekubatanidza ku40G QSFP + optical modules, uye imwe mugumo ina duplex LC jumpers yekubatanidza kune ina 10G SFP + optical modules. . Mutsara wega wega unotumira data pamwero we10Gbps kuti upedze 40G kusvika ku10G kutapurirana. Iyi sarudzo yekubatanidza inokodzera 40G yakakwirira-density network. MTP-4 * LC branch jumpers inogona kutsigira kureba kwekufambisa data kana ichienzaniswa neDAC kana AOC yakananga tambo dzekubatanidza. Sezvo michina yakawanda ichienderana neLC interfaces, MTP-4 * LC branch jumper connection scheme inogona kupa vashandisi imwe nzira inoshanduka ye wiring.

Shandisa muenzaniso: Cherechedza: Kugonesa basa rekubuda kwechiteshi 40G pane Command Line, unoda kutangazve chishandiso
Kuisa iyo CLI yekumisikidza modhi, pinda kune mudziyo kuburikidza ne serial port kana SSH Telnet. Mhanyai iyo "enable---gadzirisa terminal---interface ce0---kumhanya 40000---kubuda” inoraira munhevedzano kugonesa iyo CE0 port breakout basa. Pakupedzisira, tangazve mudziyo sezvakakumbirwa. Mushure mekutangazve, mudziyo unogona kushandiswa zvakajairika.
Mushure mekunge mudziyo watangazve, 40G chiteshi CE0 chave kubuda mu4 * 10GE ports CE0.0, CE0.1, CE0.2, uye CE0.3. Aya madoko akagadzirirwa zvakasiyana semamwe 10GE ports.
Chirongwa chemuenzaniso: ndechekugonesa basa rekuputsika kwechiteshi che40G pamutsetse wekuraira, uye kuburitsa chiteshi che40G muzvikamu zvina zve10G, izvo zvinogona kugadzirwa zvakasiyana semamwe 10G ports.
Breakout Advantages uye Zvakaipa
Zvakanakira breakout:
● Kunyanya kuwanda. Semuenzaniso, 36-port QDD breakout switch inogona kupa katatu kuwanda kweiyo switch ine single-lane downlink ports. Nokudaro kuwana nhamba yakafanana yekubatanidza uchishandisa nhamba shoma yekuchinja.
● Kusvika kune yakaderera-speed interfaces. Semuyenzaniso, iyo QSFP-4X10G-LR-S transceiver inogonesa switch ine chete QSFP ports yekubatanidza 4x 10G LR mainterface pachiteshi.
● Kuchengeta Mari. Nekuda kwekushomeka kushoma kwemidziyo yakajairwa inosanganisira chassis, makadhi, vatengesi vemagetsi, mafeni, ...
Zvakaipa zvebreakout:
● Imwe nzira yakaoma yekutsiva. Kana imwe yemachiteshi pane inoputika transceiver, AOC kana DAC, yakashata, inoda kutsiviwa kweiyo transceiver yese kana tambo.
● Kwete sezvaunokwanisa kuita. Mukuchinja ne-single-lane downlinks, chiteshi chega chega chinogadziriswa chega. Semuenzaniso, chiteshi chega chega chinogona kunge chiri 10G, 25G, kana 50G uye inogona kugamuchira chero mhando ye transceiver, AOC kana DAC. A QSFP-chete chiteshi mu breakout mode inoda nzira-yakangwara yeboka, uko ese mainterfaces e transceiver kana tambo yakafanana mhando.
