Kugeza ubu, abakoresha imiyoboro myinshi n’ibigo bikoresha amakuru bemeza QSFP + kugeza kuri SFP + yo gutandukanya ibyambu kugira ngo bazamure umuyoboro wa 10G uriho kugeza kuri 40G umuyoboro mwiza kandi uhamye kugira ngo ibyifuzo byiyongera bikwirakwizwa byihuse. Iyi gahunda yo gutandukanya ibyambu 40G kugeza 10G irashobora gukoresha byimazeyo ibikoresho byurusobe bihari, gufasha abakoresha kuzigama ibiciro, no koroshya iboneza ryurusobe. Nigute dushobora kugera kuri 40G kugeza 10G? Iyi ngingo izagabana gahunda eshatu zo kugufasha kugufasha kugera kuri 40G kugeza 10G.
Ikivuko cya Port ni iki?
Gutandukana gushoboza guhuza ibikoresho byurusobe hamwe nibyambu byihuta, mugihe ukoresha byuzuye umurongo wa port.
Uburyo bwo gutandukana kubikoresho byurusobe (switch, router, na seriveri) byugurura inzira nshya kubakoresha imiyoboro kugirango bakomeze umuvuduko wibisabwa. Mugushyiramo ibyambu byihuta byunganira gucamo, abashoramari barashobora kongera ubwinshi bwicyambu cya faceplate kandi bigafasha kuzamura ibipimo byamakuru byiyongera.
Icyitonderwa cyo kugabana 40G kugeza 10G Icyambu
Abahindura benshi mumasoko ashyigikira icyambu. Urashobora kugenzura niba igikoresho cyawe gishyigikira kugabana ibyambu ukoresheje igitabo cyahinduwe cyangwa kubaza uwaguhaye isoko. Menya ko mubihe bimwe bidasanzwe, ibyambu bihindura ntibishobora gutandukana. Kurugero, iyo switch ikora nkibabi ryibabi, bimwe mubyambu byayo ntibishyigikira gucamo ibice; Niba icyambu gihindura icyambu, icyambu ntigishobora gucikamo ibice.
Mugihe ugabanije icyambu cya 40 Gbit / s muri 4 x 10 Icyambu cya Gbit / s, menya neza ko icyambu gikoresha 40 Gbit / s kubusa kandi ntayindi mirimo ya L2 / L3 ishoboye. Menya ko muriki gikorwa, icyambu gikomeza gukora kuri 40Gbps kugeza sisitemu itangiye. Kubwibyo, nyuma yo kugabanya icyambu cya 40 Gbit / s mu byambu 4 x 10 Gbit / s ukoresheje itegeko rya CLI, ongera utangire igikoresho kugirango itegeko ritangire gukurikizwa.
QSFP + kuri SFP + Gahunda ya Cabling
Kugeza ubu, QSFP + kuri SFP + gahunda yo guhuza ikubiyemo ahanini ibi bikurikira:
QSFP + kugeza 4 * SFP + DAC / AOC Gahunda yo Guhuza Umugozi
Waba wahisemo 40G QSFP + kugeza 4 * 10G SFP + DAC umuringa wibanze wumuringa wihuta cyangwa 40G QSFP + kugeza 4 * 10G SFP + AOC umugozi ukora, guhuza bizaba kimwe kuko umugozi wa DAC na AOC urasa mubishushanyo mbonera. Nkuko bigaragara ku gishushanyo gikurikira, impera imwe ya DAC na AOC itaziguye ni 40G QSFP + ihuza, naho iyindi ni enye zitandukanye 10G SFP + ihuza. Umuhuza QSFP + ucomeka mu cyambu cya QSFP + kuri switch kandi ufite imiyoboro ine ibangikanye, buri kimwe gikora ku gipimo kigera kuri 10Gbps. Kubera ko insinga yihuta ya DAC ikoresha umuringa na AOC insinga ikora ikoresha fibre, nayo ishyigikira intera itandukanye. Mubisanzwe, insinga ya DAC yihuta ifite intera ngufi yo kohereza. Iri ni itandukaniro rigaragara hagati yibi byombi.
Muri 40G kugeza 10G itandukanijwe, urashobora gukoresha 40G QSFP + kugeza 4 * 10G SFP + insinga itaziguye kugirango uhuze na switch utaguze modulike yinyongera ya optique, uzigama ibiciro byurusobe kandi woroshye inzira yo guhuza. Ariko, intera yohereza iyi sano ni ntarengwa (DAC≤10m, AOC≤100m). Kubwibyo, insinga ya DAC cyangwa AOC irakwiriye cyane guhuza kabine cyangwa kabine ebyiri zegeranye.
40G QSFP + kugeza 4 * LC Duplex AOC Ishami rikora
40G QSFP + kugeza 4 * LC duplex ishami rya AOC ishami ryubwoko ni ubwoko bwihariye bwa kabili ikora ya AOC hamwe na QSFP + umuhuza kuruhande rumwe na LC duplex isimbuka kurundi. Niba uteganya gukoresha umugozi ukora 40G kugeza 10G, ukeneye modul enye za SFP + optique, ni ukuvuga, QSFP + interineti ya 40G QSFP + kugeza kuri 4 * LC duplex ikora irashobora kwinjizwa muburyo butaziguye ku cyambu cya 40G cyibikoresho, kandi LC Imigaragarire igomba kwinjizwa muri 10G SFP + optique ya module igikoresho. Kubera ko ibikoresho byinshi bihuza na LC interineti, ubu buryo bwo guhuza burashobora guhuza neza ibyifuzo byabakoresha benshi.
MTP-4 * LC Ishami rya Optical Fiber Jumper
Nkuko bigaragara ku gishushanyo gikurikira, impera imwe ya MTP-4 * LC isimbuka ishami ni 8-intangiriro ya MTP yo guhuza 40G QSFP + optique, naho iyindi mpera ni bine duplex LC isimbuka kugirango ihuze na bine 10G SFP + optique. . Buri murongo wohereza amakuru ku gipimo cya 10Gbps kugirango urangize 40G kugeza 10G. Iki gisubizo cyo guhuza gikwiranye na 40G imiyoboro myinshi. MTP-4 * LC isimbuka ishami rishobora gushyigikira intera ndende ugereranije na DAC cyangwa AOC insinga itaziguye. Kubera ko ibikoresho byinshi bihujwe na LC interineti, MTP-4 * LC ishami rya jumper ihuza gahunda irashobora guha abakoresha uburyo bworoshye bwo gukoresha insinga.
Nigute ushobora gucamo 40G muri 4 * 10G kuri tweMylinking ™ Umuyoboro wa Packet Broker ML-NPB-3210 + ?
Koresha urugero: Icyitonderwa: Kugirango ushoboze gucamo imikorere ya port 40G kumurongo wateganijwe, ukeneye kongera gutangira igikoresho
Kugirango winjire muburyo bwa CLI, injira mubikoresho ukoresheje icyambu cyangwa SSH Telnet. Koresha “Gushoboza---Kugena iherezo---Imigaragarire ce0---umuvuduko 40000---gucika”Amabwiriza akurikirana kugirango ashoboze imikorere ya port ya CE0. Hanyuma, ongera utangire igikoresho nkuko ubisabwe. Nyuma yo gutangira, igikoresho gishobora gukoreshwa mubisanzwe.
Igikoresho kimaze gutangira, icyambu cya 40G CE0 cyacitsemo icyambu cya 4 * 10GE CE0.0, CE0.1, CE0.2, na CE0.3. Ibyo byambu byashyizweho ukundi nkibindi byambu 10GE.
Urugero rwa porogaramu: ni ugushoboza imikorere yo gucamo icyambu cya 40G kumurongo wategeka, no gucamo icyambu cya 40G mubyambu bine 10G, bishobora gushyirwaho ukundi nkibindi byambu 10G.
Ibyiza byo gutandukana nibibi
Ibyiza byo gucika:
Ens Ubucucike buri hejuru. Kurugero, icyambu cya 36-icyuma cya QDD cyacitse gishobora gutanga inshuro eshatu ubucucike bwimikorere hamwe numurongo umwe wamanutse. Rero kugera ku mubare umwe uhuza ukoresheje umubare muto wa switch.
● Kugera kumurongo wihuta. Kurugero, transceiver ya QSFP-4X10G-LR-S ituma uhindura ufite ibyambu bya QSFP gusa kugirango uhuze 4x 10G LR kuri buri cyambu.
Kuzigama mu bukungu. Kubera gukenera ibikoresho bisanzwe birimo chassis, amakarita, abatanga amashanyarazi, abafana,…
Ingaruka zo gucika:
Strategy Ingamba zoroshye zo gusimbuza. Iyo kimwe mu byambu kuri transceiver, AOC cyangwa DAC, bigenda nabi, bisaba gusimbuza transceiver yose cyangwa umugozi.
● Ntabwo ari ibintu bisanzwe. Muguhinduranya hamwe kumurongo umwe, buri cyambu cyagizwe kugiti cyacyo. Kurugero, icyambu cyihariye gishobora kuba 10G, 25G, cyangwa 50G kandi gishobora kwakira ubwoko ubwo aribwo bwose bwa transceiver, AOC cyangwa DAC. Icyambu cya QSFP gusa muburyo bwo gutandukana bisaba itsinda ryubwenge, aho intera zose za transceiver cyangwa umugozi ari ubwoko bumwe.
