Njengamanje, iningi labasebenzisi benethiwekhi yebhizinisi kanye nesikhungo sedatha bamukela i-QSFP + kuya ku-SFP + isikimu sokuhlukaniswa kwechweba ukuze kuthuthukiswe inethiwekhi ekhona ye-10G kunethiwekhi ye-40G ngokuphumelelayo nangokuzinzile ukuze kuhlangatshezwane nesidingo esikhulayo sokudluliselwa kwesivinini esikhulu. Lesi sikimu sokuhlukanisa imbobo se-40G kuya ku-10G singasebenzisa ngokugcwele amadivayisi enethiwekhi akhona, sisize abasebenzisi bonge izindleko, futhi senze ukucushwa kwenethiwekhi kube lula. Ngakho-ke ungafinyelela kanjani ukudluliswa kwe-40G kuya ku-10G? Lesi sihloko sizokwabelana ngezikimu ezintathu zokuhlukanisa ukukusiza ukufeza ukudluliselwa kwe-40G kuya ku-10G.
Iyini i-Port Breakout?
Ukwehlukana kunika amandla ukuxhumeka phakathi kwamadivayisi enethiwekhi anezimbobo zejubane ezihlukene, kuyilapho kusetshenziswa ngokugcwele umkhawulokudonsa wembobo.
Imodi yokunqamuka kumpahla yenethiwekhi (amaswishi, amarutha, namaseva) ivula izindlela ezintsha zokuthi opharetha benethiwekhi bahambisane nesivinini sokufunwa komkhawulokudonsa. Ngokungeza izimbobo ezinesivinini esikhulu ezisekela ukuphuma, ama-opharetha angakhuphula ukuminyana kwembobo ye-faceplate futhi anike amandla ukuthuthukela kumazinga aphezulu edatha ngokwandayo.
Izinyathelo zokuqapha zokuhlukanisa i-40G kuya ku-10G Ports Breakout
Amaswishi amaningi ekuhlukaniseni imbobo yokusekela imakethe. Ungahlola ukuthi idivayisi yakho iyakusekela yini ukuhlukaniswa kwembobo ngokubhekisela kubhukwana lomkhiqizo wokushintsha noma ukubuza umphakeli. Qaphela ukuthi kwezinye izimo ezikhethekile, ukushintsha izimbobo akukwazi ukuhlukaniswa. Isibonelo, uma iswishi isebenza njengeswishi Yeqabunga, ezinye zezimbobo zayo azikusekeli ukuhlukaniswa kwembobo; Uma imbobo yokushintsha isebenza njengembobo yesitaki, imbobo ayikwazi ukuhlukaniswa.
Uma uhlukanisa imbobo engu-40 Gbit/s ibe izimbobo ezingu-4 x 10 Gbit/s, qinisekisa ukuthi imbobo isebenzisa u-40 Gbit/s ngokuzenzakalelayo futhi ayikho eminye imisebenzi ye-L2/L3 enikwe amandla. Qaphela ukuthi phakathi nale nqubo, imbobo iyaqhubeka nokusebenza ku-40Gbps kuze kube yilapho isistimu iqala kabusha. Ngakho-ke, ngemva kokuhlukanisa imbobo ye-40 Gbit/s ibe izimbobo ezingu-4 x 10 Gbit/s usebenzisa umyalo we-CLI, qala kabusha idivayisi ukuze wenze umyalo usebenze.
I-QSFP+ kuya ku-SFP+ Cabling Scheme
Njengamanje, izinhlelo zokuxhuma ze-QSFP+ kuya ku-SFP+ zifaka phakathi lokhu okulandelayo:
I-QSFP+ kuya ku-4*SFP+ DAC/AOC Direct Cable Connection Scheme
Kungakhathaliseki ukuthi ukhetha i-40G QSFP+ kuya ku-4*10G SFP+ DAC ikhebula le-copper core high-speed noma i-40G QSFP+ kuya ku-4*10G SFP+ AOC ikhebula esebenzayo, uxhumano luzofana ngoba ikhebula le-DAC ne-AOC ziyafana ngomklamo nenjongo. Njengoba kuboniswe esithombeni esingezansi, ukuphela kwekhebula eliqondile le-DAC ne-AOC liyisixhumi se-40G QSFP +, kanti esinye isiphetho sinezixhumi ezine ezihlukene ze-10G SFP +. Isixhumi se-QSFP+ sixhuma ngqo embotsheni ye-QSFP+ ekushintsheni futhi sineziteshi ezine ezihambisanayo ezimbili, ngayinye esebenza ngamanani afika ku-10Gbps. Njengoba izintambo ze-DAC ezinesivinini esikhulu zisebenzisa izintambo ezisebenzayo zethusi ne-AOC zisebenzisa i-fiber, ziphinde zisekele amabanga ahlukene okudlulisela. Ngokuvamile, izintambo ze-DAC ezinesivinini esikhulu zinamabanga amafushane wokudlulisela. Lona umehluko osobala kakhulu phakathi kwakho kokubili.
Kuxhumano oluhlukanisayo lwe-40G kuya ku-10G, ungasebenzisa i-40G QSFP + kuya ku-4 * 10G SFP + ikhebula lokuxhumana eliqondile ukuze uxhume ku-switch ngaphandle kokuthenga amamojula engeziwe optical, ukulondoloza izindleko zenethiwekhi nokwenza lula inqubo yokuxhuma. Kodwa-ke, ibanga lokudlulisela lalokhu kuxhumana lilinganiselwe (DAC≤10m, AOC≤100m). Ngakho-ke, intambo eqondile ye-DAC noma ye-AOC ifaneleka kakhulu ukuxhuma ikhabhinethi noma amakhabethe amabili aseduze.
40G QSFP+ kuya ku-4*LC Duplex AOC Branch Active Cable
I-40G QSFP+ kuya ku-4*LC duplex AOC ikhebula elisebenzayo legatsha liwuhlobo olukhethekile lwekhebula elisebenzayo le-AOC elinesixhumi se-QSFP+ ngakolunye uhlangothi kanye nama-jumper amane ahlukene e-LC duplex ngakolunye. Uma uhlela ukusebenzisa i-40G kuya ku-10G ikhebula elisebenzayo, udinga amamojula amane e-SFP + optical, okungukuthi, i-QSFP + interface ye-40G QSFP + kuya ku-4 * LC duplex cable esebenzayo ingafakwa ngokuqondile echwebeni le-40G ledivayisi, futhi I-interface ye-LC kufanele ifakwe kumojula ye-10G SFP+ ehambisanayo yedivayisi. Njengoba amadivaysi amaningi ehambisana ne-LC interfaces, le modi yokuxhuma ingahlangabezana kangcono nezidingo zabasebenzisi abaningi.
I-MTP-4*LC Yegatsha Le-Optical Fiber Jumper
Njengoba kuboniswe emfanekisweni olandelayo, umkhawulo owodwa we-MTP-4 * LC jumper yegatsha iyi-interface ye-8-core MTP yokuxhuma kumamojula we-40G QSFP + optical, kanti omunye umkhawulo une-duplex LC jumpers ezine zokuxhuma kumamojula amane we-10G SFP + optical. . Umugqa ngamunye udlulisela idatha ngesilinganiso se-10Gbps ukuze uqedele ukudluliselwa kwe-40G kuya ku-10G. Lesi sixazululo sokuxhuma sifanelekile kumanethiwekhi we-40G aphezulu. Ama-jumper egatsha e-MTP-4*LC angakwazi ukusekela ukudluliswa kwedatha yebanga elide uma kuqhathaniswa nezintambo eziqondile ze-DAC noma ze-AOC. Njengoba amadivaysi amaningi ehambisana ne-LC interfaces, uhlelo lokuxhumanisa i-MTP-4*LC yegatsha le-jumper lungahlinzeka abasebenzisi ngohlelo lwezintambo oluguquguqukayo.
Ungayikhipha kanjani i-40G ibe yi-4*10G yethuI-Mylinking™ Network Packet Broker ML-NPB-3210+ ?
Sebenzisa isibonelo: Qaphela: Ukuze unike amandla umsebenzi wokuphuma kwembobo engu-40G ku-Command Line, udinga ukuqala kabusha idivayisi
Ukufaka imodi yokumisa ye-CLI, ngena kudivayisi ngembobo ye-serial noma i-SSH Telnet. Qalisa "vumela---lungisa itheminali---isikhombimsebenzisi ce0---isivinini 40000---Phuma” imiyalo ngokulandelana ukuze inike amandla umsebenzi wokuphuma kwembobo ye-CE0. Ekugcineni, qala kabusha idivayisi njengoba uyaliwe. Ngemva kokuqala kabusha, idivayisi ingasetshenziswa ngokujwayelekile.
Ngemva kokuthi idivayisi isiqaliswe kabusha, imbobo ye-40G CE0 iye yaphumela kumachweba angu-4 * 10GE angu-CE0.0, CE0.1, CE0.2, kanye ne-CE0.3. Lezi zimbobo zilungiswa ngokuhlukana njengamanye amachweba we-10GE.
Uhlelo oluyisibonelo: ukunika amandla umsebenzi wokuphuma wembobo ye-40G emugqeni womyalo, futhi uhlukanise imbobo ye-40G ibe izimbobo ezine ze-10G, ezingalungiselelwa ngokuhlukile njengamanye amachweba we-10G.
Breakout Izinzuzo kanye Nemibi
Izinzuzo ze-breakout:
● Ukuminyana okuphezulu. Isibonelo, iswishi ye-QDD enezimbobo ezingama-36 inganikeza ukuminyana okuphindwe kathathu kweswishi enezimbobo zomzila owodwa owehlayo. Ngaleyo ndlela kufinyelelwa inombolo efanayo yokuxhumana kusetshenziswa inani elincane lokushintshwa.
● Ukufinyelela kokusebenzelana kwesivinini esiphansi. Isibonelo, i-transceiver ye-QSFP-4X10G-LR-S inika amandla iswishi enezimbobo ze-QSFP kuphela ukuxhuma izixhumanisi ze-4x 10G LR ngembobo ngayinye.
● Ukonga Kwezomnotho. Ngenxa yesidingo esincane semishini ejwayelekile okuhlanganisa i-chassis, amakhadi, abahlinzeki bamandla, abalandeli, ...
Ukungalungi kokuqhuma:
● Isu lokumiselela elinzima kakhulu. Uma enye yezimbobo ku-transceiver ephumayo, i-AOC noma i-DAC, iba kabi, idinga ukushintshwa kwayo yonke i-transceiver noma ikhebuli.
● Hhayi njengokwenza ngokwezifiso. Kumaswishi anomzila owodwa wokuxhumanisa, imbobo ngayinye ilungiswa iyodwa. Isibonelo, imbobo ngayinye ingaba yi-10G, i-25G, noma i-50G futhi ingamukela noma yiluphi uhlobo lwe-transceiver, i-AOC noma i-DAC. Imbobo ye-QSFP kuphela kumodi yokuphumula idinga indlela ehlakaniphile yeqembu, lapho zonke izixhumi ezibonakalayo ze-transceiver noma ikhebula ziwuhlobo olufanayo.
