Njengamanje, iningi labasebenzisi benethiwekhi yebhizinisi kanye nesikhungo sedatha basebenzisa uhlelo lokuhlukaniswa kwe-QSFP+ kuya ku-SFP+ ukuze bathuthukise inethiwekhi ekhona ye-10G kuya ku-40G ngempumelelo nangokuzinzile ukuze bahlangabezane nesidingo esikhulayo sokudluliselwa okusheshayo. Lolu hlelo lokuhlukaniswa kwe-40G kuya ku-10G lungasebenzisa ngokugcwele amadivayisi enethiwekhi akhona, lusize abasebenzisi bonge izindleko, futhi lwenze kube lula ukucushwa kwenethiwekhi. Ngakho-ke ungafinyelela kanjani ukudluliselwa kwe-40G kuya ku-10G? Lesi sihloko sizokwabelana ngezinhlelo ezintathu zokuhlukaniswa ukuze sikusize ufinyelele ukudluliselwa kwe-40G kuya ku-10G.
Kuyini ukuqhekeka kwePort?
Ama-breakout avumela ukuxhumana phakathi kwamadivayisi enethiwekhi anezimbobo zesivinini ezahlukene, kuyilapho kusetshenziswa ngokugcwele i-bandwidth yembobo.
Imodi yokuqhuma kwemishini yenethiwekhi (amaswishi, ama-router, kanye namaseva) ivula izindlela ezintsha zabasebenzi benethiwekhi zokuhambisana nesivinini sokufunwa kwe-bandwidth. Ngokungeza ama-port anesivinini esikhulu asekela ukuphuma kwe-bandwidth, abasebenzi bangandisa ubuningi be-port ye-faceplate futhi banike amandla ukuthuthukiswa kumazinga aphezulu wedatha kancane kancane.
Izinyathelo Zokuqapha Zokuhlukanisa Ukuqhekeka Kwamachweba angu-40G kuya ku-10G
Iningi lamaswishi emakethe lisekela ukuhlukaniswa kwembobo. Ungahlola ukuthi idivayisi yakho iyakusekela yini ukuhlukaniswa kwembobo ngokubhekisela encwadini yomkhiqizo weswishi noma ngokubuza umhlinzeki. Qaphela ukuthi kwezinye izimo ezikhethekile, ama-switch port awakwazi ukuhlukaniswa. Isibonelo, lapho iswishi isebenza njengeswishi yeLeaf, amanye ama-port ayo awasekeli ukuhlukaniswa kwembobo; Uma i-switch port isebenza njenge-stack port, i-port ayikwazi ukuhlukaniswa.
Uma uhlukanisa imbobo engu-40 Gbit/s ibe yizimbobo ezingu-4 x 10 Gbit/s, qiniseka ukuthi imbobo isebenzisa i-40 Gbit/s ngokuzenzakalelayo futhi azikho ezinye imisebenzi ye-L2/L3 ezivuliwe. Qaphela ukuthi phakathi nale nqubo, imbobo iyaqhubeka isebenza ku-40Gbps kuze kube yilapho uhlelo luqala kabusha. Ngakho-ke, ngemva kokuhlukanisa imbobo engu-40 Gbit/s ibe yizimbobo ezingu-4 x 10 Gbit/s usebenzisa umyalo we-CLI, qala kabusha idivayisi ukuze wenze umyalo usebenze.
Uhlelo Lokuxhuma Amakhebula lwe-QSFP+ kuya ku-SFP+
Njengamanje, izinhlelo zokuxhuma ze-QSFP+ kuya ku-SFP+ zifaka phakathi okulandelayo:
Uhlelo Lokuxhuma Ikhebula Eliqondile le-QSFP+ kuya ku-4*SFP+ DAC/AOC
Kungakhathaliseki ukuthi ukhetha ikhebula le-copper core eliyi-40G QSFP+ kuya ku-4*10G SFP+ DAC elisheshayo noma ikhebula elisebenzayo le-40G QSFP+ kuya ku-4*10G SFP+ AOC, uxhumano luzofana ngoba ikhebula le-DAC ne-AOC lifana ngokuklama nangenjongo. Njengoba kuboniswe esithombeni esingezansi, umkhawulo owodwa wekhebula eliqondile le-DAC ne-AOC uyisixhumanisi se-40G QSFP+, kanti omunye umkhawulo uyizixhumanisi ezine ezihlukene ze-10G SFP+ 10G. Isixhumi se-QSFP+ sixhuma ngqo echwebeni le-QSFP+ kuswishi futhi sineziteshi ezine ezihambisanayo, ngasinye esisebenza ngamanani afinyelela ku-10Gbps. Njengoba izintambo ze-DAC ezisheshayo zisebenzisa ithusi kanti izintambo ezisebenzayo ze-AOC zisebenzisa i-fiber, zisekela futhi amabanga okudlulisela ahlukene. Ngokuvamile, izintambo ze-DAC ezisheshayo zinebanga lokudlulisela elifushane. Lona umehluko osobala kakhulu phakathi kwalezi ezimbili.
Ekuxhumekeni okuhlukanisiwe okungu-40G kuya ku-10G, ungasebenzisa ikhebula lokuxhumanisa eliqondile elingu-40G QSFP+ kuya ku-4*10G SFP+ ukuze uxhumeke kuswishi ngaphandle kokuthenga amamojula engeziwe e-optical, ukonga izindleko zenethiwekhi futhi wenze lula inqubo yokuxhumanisa. Kodwa-ke, ibanga lokudlulisela lalokhu kuxhumana lilinganiselwe (DAC≤10m, AOC≤100m). Ngakho-ke, ikhebula le-DAC eliqondile noma le-AOC lifaneleka kakhulu ukuxhumanisa ikhabhinethi noma amakhabhinethi amabili aseduze.
Ikhebula Elisebenzayo Legatsha Le-AOC Eliyi-40G QSFP+ kuya ku-4*LC Duplex
Ikhebula elisebenzayo legatsha le-AOC eliyi-40G QSFP+ kuya ku-4*LC liwuhlobo olukhethekile lwekhebula elisebenzayo le-AOC elinesixhumi se-QSFP+ kolunye uhlangothi kanye nama-jumper amane ahlukene e-LC duplex kolunye uhlangothi. Uma uhlela ukusebenzisa ikhebula elisebenzayo le-40G kuya ku-10G, udinga amamojula amane e-SFP+ optical, okungukuthi, isixhumi esibonakalayo se-QSFP+ sekhebula elisebenzayo le-40G QSFP+ kuya ku-4*LC duplex singafakwa ngqo echwebeni le-40G ledivayisi, futhi isixhumi esibonakalayo se-LC kumele sifakwe kwimojula ehambelanayo ye-10G SFP+ optical yedivayisi. Njengoba amadivayisi amaningi ehambisana nezixhumi ezisebenzisana ne-LC, le modi yokuxhuma ingahlangabezana kangcono nezidingo zabasebenzisi abaningi.
I-MTP-4*LC Branch Optical Fiber Jumper
Njengoba kuboniswe esithombeni esilandelayo, umkhawulo owodwa we-MTP-4*LC branch jumper uyi-interface ye-MTP engu-8-core yokuxhuma kumamojula we-optical we-40G QSFP+, kanti omunye umkhawulo ungama-jumper e-LC angu-duplex amane okuxhuma kumamojula amane e-optical we-10G SFP+. Umugqa ngamunye udlulisa idatha ngesivinini se-10Gbps ukuze uqedele ukudluliselwa kwe-40G kuya ku-10G. Lesi sixazululo sokuxhuma sifanele amanethiwekhi aphezulu e-40G. Ama-jumper egatsha le-MTP-4*LC angasekela ukudluliselwa kwedatha ekude uma kuqhathaniswa nezintambo zokuxhuma eziqondile ze-DAC noma ze-AOC. Njengoba amadivayisi amaningi ehambisana nezixhumi ze-LC, uhlelo lokuxhuma i-jumper yegatsha le-MTP-4*LC lunganikeza abasebenzisi uhlelo lokuxhuma oluguquguqukayo kakhudlwana.
Indlela Yokuhlukanisa I-40G Ku-4*10G Ku-Umthengisi Wephakethe Lenethiwekhi ye-Mylinking™ ML-NPB-3210+ ?
Sebenzisa isibonelo: Qaphela: Ukuze unike amandla umsebenzi wokuphuma kwe-port 40G ku-Command Line, udinga ukuqala kabusha idivayisi
Ukuze ufake imodi yokucushwa kwe-CLI, ngena ngemvume kudivayisi nge-port ye-serial noma i-SSH Telnet. Sebenzisa i-“vumela---lungiselela i-terminal---isikhombimsebenzisi se-ce0---isivinini 40000---Phuma"imiyalo ngokulandelana ukuze kusebenze umsebenzi wokuqhekeka kwembobo ye-CE0. Ekugcineni, qala kabusha idivayisi njengoba uceliwe. Ngemva kokuqala kabusha, idivayisi ingasetshenziswa ngokujwayelekile.
Ngemva kokuthi idivayisi isiqaliwe kabusha, imbobo engu-40G CE0 ivele yaba amambobo angu-4 * 10GE CE0.0, CE0.1, CE0.2, kanye ne-CE0.3. La mambobo ahlelwe ngokwehlukana njengamanye amambobo angu-10GE.
Uhlelo lwesibonelo: ukunika amandla umsebenzi wokuphuma kwechweba le-40G emgqeni womyalo, bese uhlukanisa ichweba le-40G libe amachweba amane e-10G, angalungiswa ngokwehlukana njengamanye amachweba e-10G.
Izinzuzo kanye nokungalungi kokuphuma
Izinzuzo zokuqhuma:
● Ubuningi obuphezulu. Isibonelo, iswishi yokuqhuma ye-QDD enamachweba angu-36 inganikeza ubuningi obuphindwe kathathu beswishi ngamachweba okuxhumanisa omzila owodwa. Ngaleyo ndlela kufezwa inani elifanayo lokuxhumeka kusetshenziswa inani elincane lamaswishi.
● Ukufinyelela kuma-interface anesivinini esiphansi. Isibonelo, i-transceiver ye-QSFP-4X10G-LR-S ivumela ukushintsha okunama-port e-QSFP kuphela ukuxhuma ama-interface angu-4x 10G LR nge-port ngayinye.
● Ukonga Ngokwezomnotho. Ngenxa yesidingo esincane semishini evamile okuhlanganisa ishasi, amakhadi, abaphakeli bamandla, amafeni, …
Izinkinga zokuphuma kwesisu:
● Isu lokushintsha elinzima kakhulu. Uma enye yamachweba ku-transceiver ephumayo, i-AOC noma i-DAC, yonakala, idinga ukushintshwa kwe-transceiver noma ikhebula lonke.
● Akukwazi ukwenziwa ngendlela oyifisayo. Kumaswishi anezixhumanisi zokungena zomzila owodwa, imbobo ngayinye ihlelwe ngokwahlukile. Isibonelo, imbobo ngayinye ingaba yi-10G, 25G, noma i-50G futhi ingamukela noma yiluphi uhlobo lwe-transceiver, i-AOC noma i-DAC. Imbobo ye-QSFP kuphela kwimodi yokuqhuma idinga indlela yokuqonda iqembu, lapho zonke izixhumi ze-transceiver noma ikhebula ziluhlobo olufanayo.
