Okwangoku, uninzi lwabasebenzisi benethiwekhi yeshishini kunye neziko ledatha basebenzisa iskimu sokwahlulahlula izibuko ze-QSFP+ ukuya kwi-SFP+ ukuphucula inethiwekhi ekhoyo ye-10G ukuya kwinethiwekhi ye-40G ngokufanelekileyo nangokuzinzileyo ukuhlangabezana neemfuno ezikhulayo zokuhambisa ngesantya esiphezulu. Esi skimu sokwahlulahlula izibuko ze-40G ukuya kwi-10G sinokusebenzisa ngokupheleleyo izixhobo zenethiwekhi ezikhoyo, sincede abasebenzisi bonge iindleko, kwaye senze lula uqwalaselo lwenethiwekhi. Ngoko ke ungalufezekisa njani uthumelo lwe-40G ukuya kwi-10G? Eli nqaku liza kwabelana ngezikimu ezintathu zokwahlulahlula ukukunceda ufezekise uthumelo lwe-40G ukuya kwi-10G.
Yintoni iPort Breakout?
Uqhambuko lwezixhobo luvumela uqhagamshelo phakathi kwezixhobo zenethiwekhi ezineeports zesantya ezahlukeneyo, ngelixa zisebenzisa ngokupheleleyo i-bandwidth yeport.
Imo yokuqhawuka kwizixhobo zenethiwekhi (iiswitshi, ii-routers, kunye neeseva) ivula iindlela ezintsha kubaqhubi benethiwekhi zokuhambisana nesantya sokufunwa kwe-bandwidth. Ngokongeza ii-ports ezinesantya esiphezulu ezixhasa ukuqhawuka, abaqhubi banokunyusa uxinano lwee-port ze-faceplate kwaye bavumele ukuphuculwa ukuya kumazinga aphezulu edatha ngokuthe ngcembe.
Amanyathelo okuthintela ukwahlulwa kwe-40G ukuya kwi-10G Ports Breakout
Uninzi lweeswitshi kwimarike luxhasa ukwahlulwahlulwa kweezibuko. Ungajonga ukuba isixhobo sakho siyayixhasa na ukwahlulwahlulwa kweezibuko ngokubhekisa kwincwadi yemiyalelo yemveliso yeswitshi okanye ngokubuza umthengisi. Qaphela ukuba kwezinye iimeko ezikhethekileyo, iiswitshi azinakwahlulwa. Umzekelo, xa iswitshi isebenza njengeswitshi yeLeaf, ezinye zeeswitshi zayo azixhasi ukwahlulwahlulwa kweezibuko; Ukuba iswitshi isebenza njengesititshi see-stack, i-port ayinakwahlulwa.
Xa uhlulahlula izibuko ezingama-40 Gbit/s zibe ziizibuko ezingama-4 x 10 Gbit/s, qiniseka ukuba izibuko lisebenzisa i-40 Gbit/s ngokuzenzekelayo kwaye akukho eminye imisebenzi ye-L2/L3 evuliweyo. Qaphela ukuba ngeli xesha le nkqubo, izibuko liyaqhubeka nokusebenza kwi-40Gbps ide inkqubo iqalise kwakhona. Ke ngoko, emva kokwahlulahlula izibuko ezingama-40 Gbit/s zibe ziizibuko ezingama-4 x 10 Gbit/s usebenzisa umyalelo we-CLI, qalisa kwakhona isixhobo ukuze umyalelo usebenze.
Inkqubo yeentambo ze-QSFP+ ukuya kwi-SFP+
Okwangoku, iinkqubo zoqhagamshelwano ze-QSFP+ ukuya kwi-SFP+ ziquka oku kulandelayo:
Iskimu soQhagamshelo lweCable ngqo ye-QSFP+ ukuya kwi-4*SFP+ DAC/AOC
Nokuba ukhetha intambo ye-copper core ye-40G QSFP+ ukuya kwi-4*10G SFP+ DAC ekhawulezayo okanye intambo esebenzayo ye-40G QSFP+ ukuya kwi-4*10G SFP+ AOC, uqhagamshelo luya kufana kuba intambo ye-DAC kunye ne-AOC ziyafana ngoyilo kunye nenjongo. Njengoko kubonisiwe kumfanekiso ongezantsi, elinye icala lentambo ethe ngqo ye-DAC kunye ne-AOC sisixhumi se-40G QSFP+, kwaye elinye icala zizixhumi ezine ezahlukeneyo ze-10G SFP+. Isixhumi se-QSFP+ sixhuma ngqo kwizibuko le-QSFP+ kwiswitshi kwaye sineendlela ezine ezihambelanayo, nganye kuzo isebenza ngamanani afikelela kwi-10Gbps. Ekubeni iintambo ze-DAC ezikhawulezayo zisebenzisa ubhedu kwaye iintambo ezisebenzayo ze-AOC zisebenzisa ifayibha, zikwaxhasa imigama eyahlukeneyo yokudlulisela. Ngokwesiqhelo, iintambo ze-DAC ezikhawulezayo zinemigama emifutshane yokudlulisela. Lo ngumahluko ocacileyo phakathi kwezi zimbini.
Kwiqhagamshelo lokwahlulahlula lwe-40G ukuya kwi-10G, ungasebenzisa intambo yoqhagamshelo oluthe ngqo lwe-40G QSFP+ ukuya kwi-4*10G SFP+ ukuze uqhagamshele kwiswitshi ngaphandle kokuthenga iimodyuli ezongezelelweyo ze-optical, okonga iindleko zenethiwekhi kunye nokwenza lula inkqubo yoqhagamshelo. Nangona kunjalo, umgama wokudluliselwa kolu qhagamshelo ulinganiselwe (DAC≤10m, AOC≤100m). Ke ngoko, intambo ye-DAC ethe ngqo okanye ye-AOC ifanelekile ngakumbi ekuqhagamsheleni ikhabhinethi okanye iikhabhinethi ezimbini ezikufutshane.
Intambo esebenzayo ye-40G QSFP+ ukuya kwi-4*LC Duplex AOC Branch Active Cable
Intambo esebenzayo yesebe le-AOC eliyi-40G QSFP+ ukuya kwi-4*LC luhlobo olukhethekileyo lwentambo esebenzayo ye-AOC enekhonkco le-QSFP+ kwelinye icala kunye nee-jumpers ezine ze-LC duplex ezahlukeneyo kwelinye icala. Ukuba uceba ukusebenzisa intambo esebenzayo ye-40G ukuya kwi-10G, udinga iimodyuli ezine ze-SFP+ optical, oko kukuthi, ujongano lwe-QSFP+ lwentambo esebenzayo ye-40G QSFP+ ukuya kwi-4*LC duplex lunokufakwa ngqo kwi-port ye-40G yesixhobo, kwaye ujongano lwe-LC kufuneka lufakwe kwi-module ye-10G SFP+ optical yesixhobo ehambelanayo. Ekubeni uninzi lwezixhobo zihambelana nojongano lwe-LC, le ndlela yonxibelelwano inokuhlangabezana ngcono neemfuno zabasebenzisi abaninzi.
I-MTP-4*LC Branch Optical Fiber Jumper
Njengoko kubonisiwe kumfanekiso olandelayo, isiphelo esinye se-MTP-4*LC branch jumper sisinxibelelanisi se-MTP esinee-core ezisi-8 sokudibanisa kwiimodyuli ze-optical ze-40G QSFP+, kwaye esinye isiphelo zii-duplex LC jumpers ezine zokudibanisa kwiimodyuli ze-optical ezine ze-10G SFP+. Umgca ngamnye uthumela idatha ngesantya se-10Gbps ukugqiba ukudluliselwa kwe-40G ukuya kwi-10G. Esi sisombululo soqhagamshelo sifanelekile kwiinethiwekhi ze-40G eziphezulu. Ii-MTP-4*LC branch jumpers zinokuxhasa ukudluliselwa kwedatha ekude xa kuthelekiswa neentambo zoqhagamshelo oluthe ngqo lwe-DAC okanye lwe-AOC. Ekubeni uninzi lwezixhobo zihambelana ne-LC interfaces, iskimu soqhagamshelo lwe-MTP-4*LC branch jumpers sinokubonelela abasebenzisi ngeskimu socingo esiguquguqukayo ngakumbi.
Indlela yokwahlulahlula i-40G ibe yi-4*10G kwi-intanethi yethuUmthengisi wePakethi yeNethiwekhi yeMylinking™ ML-NPB-3210+ ?
Sebenzisa umzekelo: Qaphela: Ukuze usebenze umsebenzi wokuqhekeka kwezibuko ezingama-40G kuMgca woMyalelo, kufuneka uqalise kwakhona isixhobo
Ukuze ungene kwimo yoqwalaselo lwe-CLI, ngena kwisixhobo ngezibuko le-serial okanye i-SSH Telnet. Sebenzisa i-“vumela---misela isiphelo sendlela---ujongano lwe-ce0---isantya 40000---uphukela ngaphandle"imiyalelo ngokulandelelana ukuze isebenze umsebenzi wokuqhawuka kwezibuko ze-CE0. Okokugqibela, qalisa kwakhona isixhobo njengoko uceliwe. Emva kokuqalisa kwakhona, isixhobo singasetyenziswa ngokuqhelekileyo.
Emva kokuba isixhobo siqaliswe kwakhona, izibuko le-40G CE0 liye lasasazeka laba ngamazibuko ama-4 * 10GE CE0.0, CE0.1, CE0.2, kunye ne-CE0.3. La mazibuko acwangciswe ngokwahlukeneyo njengamanye amazibuko e-10GE.
Inkqubo yomzekelo: kukuvumela umsebenzi wokuqhawula i-port ye-40G kumgca womyalelo, kunye nokwahlulahlula i-port ye-40G ibe zii-port ezine ze-10G, ezinokucwangciswa ngokwahlukeneyo njengezinye ii-port ze-10G.
Iingenelo kunye nokungalungi kokuphuma kwengxaki
Iingenelo zokuqhekeka:
● Uxinano oluphezulu. Umzekelo, iswitshi yokuqhekeza ye-QDD enamachweba angama-36 inokubonelela ngoxinano oluphindwe kathathu lweswitshi ngee-downlink ports ezinendlela enye. Ngaloo ndlela kufezekisa inani elifanayo lonxibelelwano kusetyenziswa inani elincinci leswitshi.
● Ukufikelela kwii-interfaces ezinesantya esiphantsi. Umzekelo, i-transceiver ye-QSFP-4X10G-LR-S ivumela iswitshi enezikhumulo ze-QSFP kuphela ukudibanisa ii-interfaces ze-4x 10G LR nge-port nganye.
● Ukonga ngokwezoqoqosho. Ngenxa yesidingo esincinci sezixhobo eziqhelekileyo kuquka itshasi, amakhadi, ababoneleli ngombane, iifeni, …
Iingxaki zokuqhekeka:
● Icebo lokutshintsha elinzima ngakumbi. Xa enye yeeports kwi-transceiver ephumayo, i-AOC okanye i-DAC, yonakala, kufuneka itshintshwe yonke i-transceiver okanye intambo.
● Ayikwazi ukwenziwa ngokwezifiso. Kwiiswitshi ezine-downlinks zomgca omnye, i-port nganye icwangciswe ngokwahlukeneyo. Umzekelo, i-port nganye inokuba yi-10G, 25G, okanye 50G kwaye ingamkela naluphi na uhlobo lwe-transceiver, i-AOC okanye i-DAC. I-port ye-QSFP kuphela kwimodi yokuqhawuka ifuna indlela yokujonga iqela, apho zonke ii-interfaces ze-transceiver okanye intambo ziluhlobo olufanayo.
