Muri iki gihe, abakoresha benshi mu miyoboro y’itumanaho n’amakuru bakoresha gahunda yo gutandukanya imiyoboro ya QSFP+ na SFP+ kugira ngo bazamure umuyoboro wa 10G usanzweho ujya kuri 40G neza kandi mu buryo buhamye kugira ngo bahaze icyifuzo cy’itumanaho ryihuse cyane. Iyi gahunda yo gutandukanya imiyoboro ya 40G na 10G ishobora gukoresha ibikoresho by’itumanaho bihari, igafasha abakoresha kuzigama ikiguzi, kandi yoroshya imiterere y’umuyoboro. None se wakora iki kugira ngo ugere kuri 40G kugeza kuri 10G? Iyi nkuru izagaragaza gahunda eshatu zo gutandukanya imiyoboro kugira ngo igufashe kugera kuri 40G kugeza kuri 10G.
Kubura kwa Port ni iki?
Guhagarara kw'amakuru bituma habaho guhuza hagati y'ibikoresho bya interineti bifite imiyoboro itandukanye y'umuvuduko, mu gihe bikoresha uburyo bwa port bandwidth.
Uburyo bwo gusohora amakuru ku bikoresho bya interineti (switches, routers, na seriveri) bufungurira abakora porogaramu za interineti uburyo bushya bwo kugendana n'umuvuduko w'ubusabe bw'itumanaho. Mu kongeramo porogaramu zihuta cyane zishyigikira gusohora amakuru, abakora porogaramu bashobora kongera ubucucike bw'imashini za interineti no gutuma amakuru azamuka buhoro buhoro.
Amabwiriza yo kwirinda kugabanya 40G na 10G Ports Breakout
Inyinshi mu mpinduka ku isoko zishyigikira gutandukanya imiyoboro. Ushobora kugenzura niba igikoresho cyawe gishyigikira gutandukanya imiyoboro wifashishije igitabo cy'amabwiriza agenga ibicuruzwa bya switch cyangwa ubaza umutanga serivisi. Menya ko mu bihe bimwe na bimwe byihariye, imiyoboro idashobora gutandukana. Urugero, iyo switch ikora nk'ipine y'ikibabi, zimwe mu mpanuka zayo ntizishyigikira gutandukanya imiyoboro; Niba umuyoboro uhindura imiyoboro ukorera nk'ipine y'imiyoboro, umuyoboro ntushobora gutandukana.
Mu gihe ugabanya port ya 40 Gbit/s mo port za 4 x 10 Gbit/s, menya neza ko port ikoresha 40 Gbit/s mu buryo busanzwe kandi nta yindi mikorere ya L2/L3 ikora. Menya ko muri iki gikorwa, port ikomeza gukora kuri 40Gbps kugeza igihe sisitemu izongera gutangira. Kubwibyo, nyuma yo kugabanya port ya 40 Gbit/s mo port za 4 x 10 Gbit/s ukoresheje itegeko rya CLI, ongera utangire igikoresho kugira ngo itegeko rikore.
Gahunda yo gukwirakwiza insinga za QSFP+ kuva kuri SFP+
Kugeza ubu, gahunda zo guhuza QSFP+ na SFP+ zirimo ibi bikurikira:
Gahunda yo guhuza insinga za QSFP+ na 4*SFP+ DAC/AOC Direct Cable
Waba uhisemo insinga yihuta ya 40G QSFP+ kugeza kuri 4*10G SFP+ DAC y'umuringa cyangwa insinga ikora ya 40G QSFP+ kugeza kuri 4*10G SFP+ AOC, isano izaba imwe kuko insinga ya DAC na AOC bisa mu miterere n'intego. Nk'uko bigaragara ku ishusho iri hepfo, impera imwe y'insinga ya DAC na AOC ni umuhuza wa 40G QSFP+, naho impera imwe ni imihuza ine itandukanye ya 10G SFP+. Umuhuza wa QSFP+ uca mu buryo butaziguye mu muyoboro wa QSFP+ kuri switch kandi ufite imiyoboro ine iteganye, buri imwe ikora ku gipimo cya 10Gbps. Kubera ko insinga zihuta za DAC zikoresha umuringa na insinga zikora za AOC zikoresha fibre, nazo zishyigikira intera zitandukanye zo kohereza. Ubusanzwe, insinga zihuta za DAC zifite intera ngufi zo kohereza. Iri ni ryo tandukaniro rigaragara cyane hagati y'izo ebyiri.
Mu guhuza kwa 40G kugeza kuri 10G, ushobora gukoresha insinga ya 40G QSFP+ kugeza kuri 4*10G SFP+ kugira ngo uhuze na switch utiriwe ugura modules z'inyongera za optique, bikagabanya ikiguzi cy'umuyoboro kandi byoroshya inzira yo guhuza. Ariko, intera yo kohereza iyi sano ni nke (DAC≤10m, AOC≤100m). Kubwibyo, insinga ya DAC cyangwa AOC irakwiriye cyane mu guhuza akabati cyangwa utubati tubiri twegeranye.
Umugozi ukoresha 40G QSFP+ kugeza kuri 4*LC Duplex AOC Branch Active Cable
Insinga ya 40G QSFP+ kugeza kuri 4*LC duplex AOC branch active ni ubwoko bwihariye bwa insinga ya AOC active ifite umuhuza wa QSFP+ ku mpera imwe n'udupira tune twa LC duplex ku rundi ruhande. Niba uteganya gukoresha insinga ya 40G kugeza kuri 10G active, ukeneye module enye za SFP+ optique, ni ukuvuga ko umuhuza wa QSFP+ wa insinga ya 40G QSFP+ kugeza kuri 4*LC duplex active ushobora gushyirwa mu buryo butaziguye mu muyoboro wa 40G w'igikoresho, kandi umuhuza wa LC ugomba gushyirwa muri module ya 10G SFP+ optique y'igikoresho. Kubera ko ibikoresho byinshi bihuye na interface za LC, ubu buryo bwo guhuza bushobora guhaza neza ibyo abakoresha benshi bakeneye.
Ijagi rya MTP-4*LC ry'ishami rya optique fibre jumper
Nkuko bigaragara ku ishusho ikurikira, impera imwe ya MTP-4 * LC branch jumper ni interface ya MTP ifite core 8 yo guhuza na modules za 40G QSFP + optique, naho impera yindi ni duplex LC jumpers enye zo guhuza na modules enye za 10G SFP + optique. Buri murongo wohereza amakuru ku gipimo cya 10Gbps kugira ngo urangize transmission ya 40G kuri 10G. Iyi connection solution ikwiriye imiyoboro ya 40G ifite ubucucike bwinshi. MTP-4 * LC branch jumpers zishobora gushyigikira transmission y'amakuru kure ugereranije na DAC cyangwa AOC direct connection inches. Kubera ko ibikoresho byinshi bihuye na LC interfaces, MTP-4 * LC branch jumper connection scheme ishobora guha abayikoresha uburyo bworoshye bwo guhuza insinga.
Uburyo bwo gukuramo 40G muri 4*10G kuri mudasobwa yacuUmuhuzabikorwa wa Mylinking™ Network Packet ML-NPB-3210+ ?
Koresha urugero: Icyitonderwa: Kugira ngo ukoreshe imikorere ya port 40G kuri Command Line, ugomba kongera gutangiza igikoresho
Kugira ngo winjire muri CLI configuration mode, injira muri igikoresho unyuze kuri serial port cyangwa SSH Telnet. Koresha "shoboza---gena terminal---imbuga ikoresha ce0---umuvuduko 40000---gucika kw'icumu"amabwiriza akurikiranye kugira ngo ukoreshe uburyo bwo guhagarika umuyoboro wa CE0. Amaherezo, ongera utangire igikoresho nkuko byasabwe. Nyuma yo kongera gutangira, igikoresho gishobora gukoreshwa mu buryo busanzwe.
Nyuma yuko igikoresho gitangiye kongera gukoreshwa, pouvo ya 40G CE0 yashyizwemo pouvo 4 * 10GE CE0.0, CE0.1, CE0.2, na CE0.3. Izi pouvo zashyizwe mu buryo butandukanye nk'izindi pouvo za 10GE.
Urugero rwa porogaramu: ni ugukoresha uburyo bwo gusohora umurongo wa 40G ku murongo w'amabwiriza, no gutandukanya umurongo wa 40G mo imiyoboro ine ya 10G, ishobora gushyirwaho ukwayo nk'indi miyoboro ya 10G.
Ibyiza n'ibibi byo gucika kw'ingufu
Ibyiza byo gucika kw'ijisho:
● Ubucucike bwinshi. Urugero, switch ya QDD ifite imiyoboro 36 ishobora gutanga ubucucike buruta inshuro eshatu bwa switch hamwe na ports zo kumanuka ku murongo umwe. Bityo bigatuma habaho umubare umwe w'imiyoboro hakoreshejwe umubare muto w'imiyoboro.
● Kubona aho ukoresha umuvuduko muto. Urugero, transceiver ya QSFP-4X10G-LR-S ituma switch ifite aho ukoresha QSFP gusa ihuza aho ukoresha 4x 10G LR kuri buri konti.
● Kuzigama mu buryo bw'ubukungu. Kubera ko hakenewe ibikoresho bisanzwe birimo chassis, amakarita, abatanga amashanyarazi, abafana, …
Ingaruka mbi zo gucika kw'ijisho:
● Ingamba zigoye zo gusimbuza. Iyo imwe mu nzira iri kuri transceiver ihita ihinduka, AOC cyangwa DAC, ibaye mbi, bisaba gusimbuza transceiver yose cyangwa insinga.
● Ntabwo ihinduka uko isanzwe imeze. Mu buryo busanzwe, buri muyoboro ushyirwaho ukwawo. Urugero, umuyoboro umwe ushobora kuba 10G, 25G, cyangwa 50G kandi ushobora kwakira ubwoko ubwo aribwo bwose bwa transceiver, AOC cyangwa DAC. Umuyoboro wa QSFP gusa mu buryo bwo gusohora amakuru usaba uburyo bwo gukoresha itsinda, aho imiyoboro yose ya transceiver cyangwa insinga ari ubwoko bumwe.
