Parizvino, vazhinji vanoshandisa network yemakambani nedata center vanoshandisa nzira yeQSFP+ kuenda kuSFP+ port breakout splitting scheme kuti vagadzirise network iripo ye10G kuenda ku40G network zvinobudirira uye zvakadzikama kuti vasangane nekuwedzera kuri kudiwa kwekutumira nekukurumidza. Iyi 40G kuenda ku10G port splitting scheme inogona kushandisa zvizere zvishandiso zvenetwork zviripo, kubatsira vashandisi kuchengetedza mari, uye kurerutsa network configuration. Saka ungawana sei 40G kuenda ku10G transmission? Chinyorwa chino chichagovera nzira nhatu dzekuparadzanisa kuti dzikubatsire kuwana 40G kuenda ku10G transmission.
Chii chinonzi Port Breakout?
Kuputika kunobvumira kubatana pakati pemidziyo yenetwork ine maports akasiyana ekumhanya, ukuwo ichishandisa zvizere bandwidth yeport.
Kubuda kwedata pamidziyo yenetwork (maswichi, marouter, uye maseva) kunovhura nzira itsva dzekuti vashandisi venetwork vaenderane nekumhanya kwekudiwa kwebandwidth. Nekuwedzera maports anomhanya zvakanyanya anotsigira kubuda kwedata, vashandisi vanogona kuwedzera huwandu hwemaports epa faceplate uye kugonesa kusimudzira data kusvika padanho repamusoro zvishoma nezvishoma.
Nzira dzekudzivirira pakupatsanura 40G kusvika 10G Ports Breakout
Maswichi mazhinji ari mumusika anotsigira kupatsanurwa kwechiteshi. Unogona kutarisa kana mudziyo wako uchitsigira kupatsanurwa kwechiteshi nekutarisa bhuku rezvigadzirwa zvechishandiso chechinji kana kubvunza mutengesi. Cherechedza kuti mune dzimwe nguva dzakakosha, maswichi haagone kupatsanurwa. Semuenzaniso, kana switch ichishanda seLeaf switch, mamwe maswichi ayo haatsigire kupatsanurwa kwechiteshi; Kana switch port ichishanda sestack port, chiteshi hachigone kupatsanurwa.
Pakupatsanura chiteshi che40 Gbit/s kuita chiteshi che4 x 10 Gbit/s, iva nechokwadi chekuti chiteshi chinomhanya 40 Gbit/s uye hapana mamwe mabasa eL2/L3 anogoneswa. Cherechedza kuti panguva iyi, chiteshi chinoramba chichishanda pa40Gbps kusvika sisitimu yatangazve. Saka, mushure mekupatsanura chiteshi che40 Gbit/s kuita chiteshi che4 x 10 Gbit/s uchishandisa murairo weCLI, tangazve mudziyo kuti murairo utange kushanda.
QSFP+ kuenda kuSFP+ Cabling Scheme
Parizvino, zvirongwa zvekubatanidza QSFP+ kuenda kuSFP+ zvinosanganisira zvinotevera:
QSFP+ kuenda ku4*SFP+ DAC/AOC Direct Cable Connection Scheme
Kunyangwe ukasarudza tambo ye 40G QSFP+ kusvika 4*10G SFP+ DAC copper core high-speed kana tambo inoshanda ye 40G QSFP+ kusvika 4*10G SFP+ AOC, kubatana kuchave kwakafanana nekuti tambo ye DAC ne AOC dzakafanana mukugadzirwa uye chinangwa. Sezvakaratidzwa mumufananidzo uri pazasi, mugumo mumwe wetambo yakananga ye DAC ne AOC i connector ye 40G QSFP+, uye mumwe mugumo une zvibatanidza zvina zvakasiyana zve 10G SFP+. Chinobatanidza che QSFP+ chinobatanidzwa zvakananga mu QSFP+ port pa switch uye chine nzira ina dzakafanana dze bidirectional, imwe neimwe inoshanda nemitengo inosvika 10Gbps. Sezvo tambo dze DAC high-speed dzichishandisa copper uye tambo dze AOC active dzichishandisa fiber, dzinotsigirawo madaro akasiyana ekutumira. Kazhinji, tambo dze DAC high-speed dzine madaro mapfupi ekutumira. Uyu ndiwo musiyano uri pachena pakati pezviviri izvi.
Mukubatana kwakapatsanurwa kwe40G kusvika 10G, unogona kushandisa tambo yekubatanidza yakananga ye40G QSFP+ kusvika 4*10G SFP+ kuti ubatanidze kuswitch pasina kutenga mamwe ma optical modules, zvichideredza mari yenetwork uye zvichiita kuti nzira yekubatanidza ive nyore. Zvisinei, daro rekutumira kwekubatana uku rakaganhurirwa (DAC≤10m, AOC≤100m). Saka, tambo yeDAC yakananga kana AOC yakakodzera kubatanidza kabhineti kana makabhineti maviri ari pedyo.
40G QSFP+ kusvika ku4*LC Duplex AOC Branch Active Cable
Tambo inoshanda ye40G QSFP+ kusvika 4*LC duplex AOC branch imhando yakasarudzika yetambo inoshanda yeAOC ine QSFP+ connector kune rimwe divi uye mana akasiyana LC duplex jumpers kune rimwe divi. Kana uchida kushandisa tambo inoshanda ye40G kusvika 10G, unoda ma SFP+ optical modules mana, kureva kuti, QSFP+ interface ye 40G QSFP+ kusvika 4*LC duplex active cable inogona kuiswa zvakananga mu 40G port yemudziyo, uye LC interface inofanira kuiswa mu 10G SFP+ optical module inoenderana yemudziyo. Sezvo michina mizhinji ichishanda ne LC interfaces, iyi connection mode inogona kusangana zviri nani nezvinodiwa nevashandisi vazhinji.
Jumper yeMTP-4*LC yeBazi reOptical Fiber
Sezvakaratidzwa mumufananidzo unotevera, mugumo mumwe weMTP-4*LC branch jumper ine 8-core MTP interface yekubatanidza kune 40G QSFP+ optical modules, uye mumwe mugumo une duplex LC jumpers ina dzekubatanidza kune mana 10G SFP+ optical modules. Mutsetse wega wega unotumira data nechiyero che10Gbps kuti upedze 40G kusvika 10G transmission. Iyi connection solution yakakodzera kune 40G high-density networks. MTP-4*LC branch jumpers inogona kutsigira kuendesa data kure kure zvichienzaniswa neDAC kana AOC direct connection cables. Sezvo michina yakawanda ichienderana neLC interfaces, MTP-4*LC branch jumper connection scheme inogona kupa vashandisi wiring scheme inochinjika zviri nyore.
Maitiro ekubvisa 40G kuita 4*10G pakombuta yeduMutengesi wePaketi yeMambure eMylinking™ ML-NPB-3210+ ?
Shandisa muenzaniso: Cherechedza: Kuti ugonese basa rekuvhara rechiteshi che40G paCommand Line, unofanira kutangazve mudziyo.
Kuti upinde muCLI configuration mode, pinda mu device uchishandisa serial port kana SSH Telnet. Mhanya “gonesa---gadzirisa terminal---interface ce0---kumhanya 40000---kubuda"mirairo yakatevedzana kuti igonese CE0 port breakout function. Pakupedzisira, tangazve mudziyo sezvawakakurudzirwa. Mushure mekutangisazve, mudziyo unogona kushandiswa zvakajairika.
Mushure mekunge mudziyo watangwazve, chiteshi che40G CE0 chave kubuda mumachiteshi mana e10GE CE0.0, CE0.1, CE0.2, uye CE0.3. Machiteshi aya akagadzirwa zvakasiyana semamwe machiteshi e10GE.
Muenzaniso wechirongwa: ndechekugonesa basa rekubvisa data re40G port pamutsetse wekuraira, uye kubvisa data re40G port kuita maport mana e10G, ayo anogona kugadziriswa zvakasiyana semamwe maport e10G.
Mabhenefiti neKuipa kweKutanga Kwemitambo
Zvakanakira kubuda kweropa:
● Kuwanda kwehuwandu. Semuenzaniso, switch yeQDD ine maports makumi matatu nematanhatu inogona kupa huwandu hwehuremu hweswitch ne single-lane downlink ports. Izvi zvinoita kuti pave nehuwandu hwakafanana hwekubatanidza uchishandisa maswitch mashoma.
● Kupinda muma interfaces ane kumhanya kwakaderera. Semuenzaniso, transceiver yeQSFP-4X10G-LR-S inogonesa switch ine ma QSFP ports chete kubatanidza ma interfaces e4x 10G LR pa port imwe neimwe.
● Kuchengetedza Mari. Nekuda kwekushomeka kwezvishandiso zvakajairika zvinosanganisira chassis, makadhi, vatengesi vemagetsi, mafeni, …
Zvakashata zvekuputika:
● Nzira yekutsiva yakaoma zvikuru. Kana imwe yenzvimbo dziri pa transceiver inobuda, AOC kana DAC, ikatadza kushanda zvakanaka, zvinoda kuti transceiver yese kana tambo itsiviwe.
● Hazvigoneke kugadziriswa. Mumaswichi ane ma downlink emunzira imwe chete, chiteshi chega chega chakagadzirwa chimwe nechimwe. Semuenzaniso, chiteshi chega chega chinogona kuva 10G, 25G, kana 50G uye chinogona kugamuchira chero rudzi rwe transceiver, AOC kana DAC. Chiteshi cheQSFP-only chiri mu breakout mode chinoda nzira yeboka, uko ma interface ese e transceiver kana cable ari emhando imwe chete.
