Njengamanje, iningi lenethiwekhi yamabhizinisi nabasebenzisi bedatha bamukele i-QSFP + kwi-SFP + Port Breakout Screating Scheme ukuze bathuthukise inethiwekhi ye-10G ekhona ngempumelelo ye-10G inethiwekhi yokudluliselwa okusheshayo. Lesi sikimu se-40G kuya ku-10G Skingting Screeme singasebenzisa ngokugcwele amadivaysi enethiwekhi akhona, sisiza abasebenzisi ukuthi balondoloze izindleko, futhi benze lula ukumiswa kwenethiwekhi. Ngakho-ke ungakufinyelela kanjani u-40g ukuhanjiswa kwe-10G? Le ndatshana izokwabelana ngezinhlelo ezintathu zokuhlukanisa izinkampani ukukusiza ukufezekisa i-40g ukuhanjiswa kwe-10G.
Yini i-port breakout?
I-Breakout inika amandla ukuxhumana phakathi kwamadivayisi wenethiwekhi anamachweba ahlukile wejubane, ngenkathi usebenzisa ngokuphelele i-port bandwidth.
Imodi ye-Breakout emishini yenethiwekhi (ukushintshwa, ama-routers, kanye namaseva) uvula izindlela ezintsha zokusebenza kwenethiwekhi ukuhambisana nejubane lesidingo se-bandwidth. Ngokwengeza amachweba asheshe axhase ukuqhekeka, opharetha bangangezelela ukulungiswa kwePortPlate Port futhi banise ukuthuthukiswa kumanani aphezulu wedatha ngokwengeziwe.
Izindlela zokuvimbela ukuhlukanisa ama-40g kuya ku-10G ports breakout
Ukushintshwa okuningi ethekwini lokusekelwa kwemakethe. Ungahlola ukuthi ngabe idivaysi yakho isekela amatheku ihlukanisa ngokubhekisela kwincwajana yomkhiqizo we-switch noma ekubuzeni umphakeli. Qaphela ukuthi kwamanye amacala akhethekile, amachweba okushintsha awakwazi ukwehlukaniswa. Isibonelo, lapho i-statch isebenza njengokushintsha kwamaqabunga, amanye amachweba awo awasekeli ukuqhekeka kwetheku; Uma i-switch port isebenza njenge-port stack, itheku alikwazi ukwehlukaniswa.
Lapho uhlukanisa itheku / ethekwini le-gbit / ama-4 10 gbit / s, uqinisekise ukuthi itheku ligijimisa ama-gbit / s ngokuzenzakalelayo futhi akukho eminye imisebenzi ye-L2 / L3 enikwe amandla. Qaphela ukuthi phakathi nale nqubo, itheku liyaqhubeka nokugijima kuma-40GBPS kuze kube yilapho uhlelo luqala kabusha. Ngakho-ke, ngemuva kokuhlukanisa itheku le-gbit / s / s libe amachweba ama-4 x 10 gbit / s asebenzisa umyalo we-CLI, qala kabusha idivaysi ukwenza umyalo uqale ukusebenza.
I-QSFP + ku-SFP + CABLIng Scheme
Okwamanje, i-QSFP + ezinhlelweni zokuxhumana ze-SFP + zifaka phakathi okulandelayo:
I-QSFP + kuya ku-4 * SFP + DAC / AOC Direct Cable Rection Prection Rection Scheme
Noma ngabe ukhetha i-40g QSFP + kuya ku-4 * 10G SFP + DAC CREPP CORE-SPEED ikhebula noma i-40g QSFP + ikhebula elisebenzayo le-4 * Njengoba kukhonjisiwe kwisibalo esingezansi, ukuphela okukodwa kwe-DAC ne-AOC CRECTICE CHECK kuyinto 40G QSFP + Isixhumi, kanti okunye kungukuphela kwezixhumi ezine ezihlukile ze-SFP SFP +. I-qsfp + plugs plugs ngqo kwi-QSFP + Port on the switch futhi ineziteshi ezine ezifanayo zokuzivocavoca, ngalinye lisebenza ngamanani afinyelela ku-10GBPS. Kusukela amakhebuli wejubane le-DAC asebenzisa amakhebudi asetshenzisiwe yi-Copper nama-aoc asebenzayo, abuye asekele amabanga ahlukene okuhambisa. Imvamisa, izintambo zesivinini se-DAC zinamabanga amafushane okuhambisa amabanga. Lo mehluko osobala kakhulu phakathi kwalokhu okubili.
Esikhathini esingu-40g kuya ku-10G Split Connection, ungasebenzisa i-40g QSFP + kuya ku-4 * 10G SFP + ikhebula lokuxhuma okuqondile ukuxhuma ku-switch angeziwe, ukonga izindleko zenethiwekhi nokwenza lula inqubo yokuxhumeka. Kodwa-ke, ibanga lokuhambisa lalokhu kuxhumeka lilinganiselwe (DAC≤10M, AOC≤100M). Ngakho-ke, ikhebula le-Direct DAC noma le-AOC lilungele kakhulu ukuxhuma iKhabhinethi noma amakhabethe amabili asondelene.
I-40G QSFP + kuya ku-4 * LC Duplex AOC i-Cable Cable esebenzayo
I-40g QSFP + kuya ku-4 * LC Duplex AOC I-CABLE CARCH uhlelo lwekhebula olusebenzayo nge-QSFP + isixhumi esiphelweni esisodwa kanye nama-LC duplex jumplers kolunye. Uma uhlela ukusebenzisa ikhebula elisebenzayo le-40G, udinga amamojula amane we-SFP + adinga ikhebula le-40g qsfp + kuya ku-LC SPEPS kufanele lifakwe kwimodyuli ehambisanayo ye-10G SFP + ye-Optical Module yedivayisi. Njengoba iningi lamadivayisi lihambisana nezindawo zokuxhumana ze-LC, le ndlela yokuxhumana ingahlangabezana kangcono nezidingo zabasebenzisi abaningi.
I-MTP-4 * LC Branch Optical Fiber jumper
Njengoba kukhonjisiwe kulokhu okulandelayo, ukuphela okukodwa kwe-MTP-4 LC I-jumper ye-MTP-4 ye-LC kuyinto esibonakalayo se-8-CORE MTP sokuxhuma + amamojula we-optical lc amamojula amane okuxhumanisa amamojula amane we-10G SFP +. Umugqa ngamunye udlulisa idatha ngesilinganiso se-10GBPS ukuqedela ukudluliselwa kwe-40g kuya ku-10G. Lesi sixazululo sokuxhumeka silungele amanethiwekhi aphezulu angama-40G aphezulu. I-MTP-4 * LC yegatsha le-LC lingasekela ukuhanjiswa kwedatha yebanga elide kuqhathaniswa nezintambo zokuxhumana ze-DAC noma ze-AOC. Njengoba iningi lamadivayisi lihambisana nezindawo zokuxhumana ze-LC, uhlelo lwe-MTP-4 * LC lwe-jumper jumper uxhumano lunganikeza abasebenzisi ngohlelo oluguquguqukayo lwe-wiring oluguquguqukayo.
Ungahlukana kanjani 40g ku-4 * 10G yethuI-MyLinking ™ Network Packet Broker ML-NPB-3210 + ?
Sebenzisa Isibonelo: Qaphela: Ukunika amandla umsebenzi wokuqhekeka wePort 40g kulayini womyalo, udinga ukuqala kabusha ithuluzi
Ukufaka imodi yokucushwa ye-CLI, ngena ngemvume kudivayisi ngokusebenzisa i-serial port noma i-ssh telnet. Gijimani "nika amandla---Lungiselela i-terminal---I-interface ce0---Ijubane 40000---Phuma"Imiyalo ngokulandelana ukunika amandla umsebenzi we-CEP Port Breakout. Ekugcineni, qala kabusha idivaysi njengoba utshelwe. Ngemuva kokuqala kabusha, idivaysi ingasetshenziswa ngokujwayelekile.
Ngemuva kokuthi ucingo luqalise kabusha, i-40G Port CE0 ibilokhu iQhubeka ku-4 * 10GE Ports CE0.0, CE0.1, CE0.1, CE0.1, FE0.3. Lawa machweba alungiselelwe ngokwahlukana njengamanye amachweba ayi-10.
Uhlelo lweSibonelo: ukunika amandla umsebenzi wokuqhekeka kwetheku le-40g emugqeni womyalo, futhi uqhume imbobo engama-40g ibe amachweba amane we-10g, angahle alungiswe ngokwehlukana njengamanye amachweba we-10g.
Ukuqhekeka kwezinzuzo nobubi
Izinzuzo zokuqhekeka:
● Ubuningi obuphezulu. Isibonelo, ukushintshwa kwe-QDD eqhekekile kwe-36-Port Ngakho-ke ukufeza inani elifanayo lokuxhuma usebenzisa inombolo encane yokushintshwa.
● Ukutholwa kwezindawo ezinesivinini esiphansi. Isibonelo, i-QSFP-4X10G-LR-S transceiver inika amandla ukushintshela ngamachweba we-QSFP ukuxhuma indawo ye-4x 10G LR ngetheku ngalinye.
● Ukonga Kwezomnotho. Ngenxa yesidingo esincane semishini ejwayelekile kufaka phakathi i-chassis, amakhadi, abahlinzeki bamandla, abalandeli, ...
Okubi kokuqhekeka:
● Isu elibuyiselwe ngaphezulu lokungena esikhundleni. Lapho elinye lamachweba e-transceiver ye-breakout, i-AOC noma i-DAC, liya kubi, lidinga ukushintshwa kwalo lonke i-transceiver noma ikhebula.
● Hhayi njengezifiso. Ekushintsheni nge-down-ye-lingle-lane downlinks, itheku ngalinye lilungiselelwe. Isibonelo, ichweba ngalinye lingaba ngu-10G, 25g, noma i-50g futhi lamukela noma yiluphi uhlobo lwe-transceiver, aoc noma i-DAC. I-ndfp-kuphela port in mode ye-breakout idinga indlela ehlakaniphile yeqembu, lapho konke ukuhlangana kwe-transceiver noma ikhebula kuluhlobo olufanayo.
