Okwangoku, uninzi lwabasebenzisi benethiwekhi yamashishini kunye nabasebenzisi beziko ledatha bamkela i-QSFP + kwi-SFP + isikimu sokuqhawula i-port breakout ukuze kuphuculwe inethiwekhi ekhoyo ye-10G kwinethiwekhi ye-40G ngokufanelekileyo kwaye ngokuzinzileyo ukuhlangabezana nemfuno ekhulayo yokuhanjiswa kwesantya esiphezulu. Le 40G ukuya kwi-10G isikimu sokuhlukanisa i-port inokusebenzisa ngokupheleleyo izixhobo zenethiwekhi ezikhoyo, ukunceda abasebenzisi ukugcina iindleko, kunye nokwenza lula ukucwangciswa kwenethiwekhi. Ngoko ukuphumeza njani i-40G kwi-10G yokudluliselwa? Eli nqaku liza kubelana ngezicwangciso ezintathu zokukunceda ukufezekisa i-40G kwi-10G yokudluliselwa.
Yintoni iPort Breakout?
Ukuqhekeka kuvumela unxibelelwano phakathi kwezixhobo zenethiwekhi ezineezibuko ezahlukeneyo zesantya, ngelixa zisebenzisa ngokupheleleyo i-bandwidth ye-port.
Imowudi yokuqhawuka kwizixhobo zenethiwekhi (ukutshintsha, iirotha, kunye neeseva) zivula iindlela ezintsha zabaqhubi benethiwekhi ukuze bahambisane nesantya semfuno ye-bandwidth. Ngokudibanisa amazibuko anesantya esiphezulu axhasa ukuqhawuka, abaqhubi banokonyusa uxinaniso lwezibuko le-faceplate kwaye benze uphuculo kumazinga aphezulu edatha ngokunyukayo.
Izilumkiso zokwahlula i-40G ukuya kwi-10G ye-Ports Breakout
Uninzi lokutshintsha kwi-port yenkxaso yemarike yokwahlula. Ungajonga ukuba isixhobo sakho siyakuxhasa na ukwahlula izibuko ngokubhekisa kwincwadana yemigaqo yemveliso okanye ubuze umboneleli. Qaphela ukuba kwezinye iimeko ezikhethekileyo, ukutshintsha izibuko azinakwahlulwa. Umzekelo, xa iswitshi isebenza njengotshintsho lweLeaf, ezinye zezibuko zayo azikuxhasi ukwahlula kwezibuko; Ukuba izibuko lokutshintsha lisebenza njengezibuko lestack, izibuko alinakwahlulwa.
Xa usahlula i-40 Gbit/s port kwi-4 x 10 Gbit/s port, qinisekisa ukuba i-port iqhuba i-40 Gbit/s ngokungagqibekanga kwaye akukho minye imisebenzi ye-L2/L3 yenziweyo. Qaphela ukuba ngexesha lale nkqubo, i-port iyaqhubeka isebenza kwi-40Gbps de inkqubo iqale kwakhona. Ngoko ke, emva kokwahlula i-40 Gbit / s port kwi-4 x 10 Gbit / s izibuko usebenzisa umyalelo we-CLI, qalisa kwakhona isixhobo ukwenza umyalelo usebenze.
I-QSFP+ ukuya kwiSFP+ Cabling Scheme
Okwangoku, i-QSFP+ ukuya kwi-SFP+ izikimu zoqhagamshelo ikakhulu ziquka oku kulandelayo:
I-QSFP+ ukuya kwi-4* SFP+ DAC/AOC iSikimu sokuQhagamshela iCable Direct
Ingaba ukhetha i-40G QSFP + kwi-4 * 10G SFP + i-DAC i-copper core high-speed cable okanye i-40G QSFP + ukuya kwi-4 * 10G SFP + AOC ikhebula elisebenzayo, uxhulumaniso luya kufana kuba i-DAC kunye ne-AOC ikhebula zifana ngokuyila kunye nenjongo. Njengoko kuboniswe kumzobo ongezantsi, enye isiphelo se-DAC kunye ne-AOC ikhebula elithe ngqo yi-40G QSFP + isixhumi, kwaye esinye isiphelo sinezixhumi ezine ezihlukeneyo ze-10G SFP +. I-QSFP + iplagi yokudibanisa ngokuthe ngqo kwi-port ye-QSFP + kwi-switch kwaye ineendlela ezine ezihambelanayo ze-bidirectional channels, nganye esebenza kumazinga ukuya kwi-10Gbps. Ekubeni iintambo ze-DAC ezinesantya esiphezulu zisebenzisa ubhedu kunye neentambo ezisebenzayo ze-AOC zisebenzisa ifayibha, zikwaxhasa imigama eyahlukeneyo yothumelo. Ngokwesiqhelo, iintambo zeDAC ezinesantya esiphezulu zinemigama emifutshane yothumelo. Lo ngowona mahluko ucacileyo phakathi kwezi zimbini.
Kwi-40G ukuya kwi-10G yokudibanisa ukuhlukana, ungasebenzisa i-40G QSFP + kwi-4 * 10G SFP + intambo yokudibanisa ngokuthe ngqo ukuxhuma kwi-switch ngaphandle kokuthenga iimodyuli ezongezelelweyo ze-optical, ukugcina iindleko zenethiwekhi kunye nokwenza lula inkqubo yokudibanisa. Nangona kunjalo, umgama wokudluliselwa kolu xhulumaniso ulinganiselwe (DAC≤10m, AOC≤100m). Ngoko ke, i-DAC ngqo okanye i-AOC cable ifanelekile ngakumbi ukudibanisa ikhabhinethi okanye iikhabhinethi ezimbini ezikufutshane.
I-40G QSFP + ukuya kwi-4 * LC Duplex AOC Ikhebula eliSebenzayo leSebe
I-40G QSFP + ukuya kwi-4 * LC duplex ye-AOC yesebe intambo esebenzayo luhlobo olukhethekileyo lwekhebula elisebenzayo le-AOC kunye ne-QSFP + ikhonkco kwelinye icala kunye ne-LC duplex jumpers ezine ezihlukeneyo kwelinye. Ukuba uceba ukusebenzisa i-40G ukuya kwi-10G ikhebula elisebenzayo, udinga iimodyuli ezine ze-SFP + optical, oko kukuthi, i-QSFP + interface ye-40G QSFP + ukuya kwi-4 * LC duplex cable esebenzayo inokufakwa ngokuthe ngqo kwi-40G port yesixhobo, kwaye I-interface ye-LC kufuneka ifakwe kwimodyuli ye-optical ye-10G ye-SFP + yesixhobo. Ekubeni izixhobo ezininzi zihambelana ne-LC interfaces, le ndlela yokudibanisa inokuhlangabezana ngcono neemfuno zabasebenzisi abaninzi.
I-MTP-4 * LC yeSebe le-Optical Fiber Jumper
Njengoko kuboniswe kulo mfanekiso ulandelayo, enye isiphelo se-MTP-4 * i-LC jumper yesebe yi-8-core MTP interface yokudibanisa ne-40G QSFP + iimodyuli ze-optical, kunye nesinye isiphelo sine-duplex ezine ze-LC jumpers zokudibanisa kwiimodyuli ezine ze-10G SFP + optical. . Umgca ngamnye uhambisa idatha kwizinga le-10Gbps ukugqiba i-40G ukuya kwi-10G yokudluliselwa. Esi sisombululo soxhumo sifanelekile kwi-40G inethiwekhi ephezulu yoxinaniso. I-MTP-4 * i-LC jumpers yesebe inokuxhasa ukuhanjiswa kwedatha yomgama omde xa kuthelekiswa ne-DAC okanye i-AOC yokudibanisa ngqo iintambo. Ekubeni izixhobo ezininzi zihambelana ne-LC interfaces, i-MTP-4 * i-LC ye-jumper ye-branch ye-scheme yoxhumo inokubonelela abasebenzisi ngeskimu se-wiring eguquguqukayo.
Ungayikhupha njani i-40G kwi-4 * 10G yethuMylinking™ Network Packet Broker ML-NPB-3210+ ?
Sebenzisa umzekelo: Qaphela: Ukwenza umsebenzi wokuqhawuka kwe-40G kwi-Command Line, kufuneka uqale kabusha isixhobo
Ukufaka imo yoqwalaselo lwe-CLI, ngena kwisixhobo nge-serial port okanye i-SSH Telnet. Qhuba "yenza---qwalasela i-terminal---ujongano ce0---isantya 40000---uphukela ngaphandle” iyalela ngolandelelwano ukwenza i-CE0 isebenze izibuko. Ekugqibeleni, qalisa kwakhona isixhobo njengoko uyalelwe. Emva kokuqalisa kwakhona, isixhobo sinokusetyenziswa ngokuqhelekileyo.
Emva kokuba isixhobo siqaliswe kwakhona, i-40G port CE0 iye yaqhambuka kwi-4 * 10GE izibuko ze-CE0.0, CE0.1, CE0.2, kunye ne-CE0.3. La mazibuko aqwalaselwe ngokwahlukeneyo njengamanye amazibuko e-10GE.
Inkqubo yomzekelo: kukwenza umsebenzi wokuqhawula i-port ye-40G kumgca womyalelo, kunye nokuqhawula i-port ye-40G kwii-port ezine ze-10G, ezinokuthi ziqwalaselwe ngokwahlukileyo njengamanye amachweba e-10G.
Ukuqhekeka okuluncedo kunye nokungalunganga
Izinto eziluncedo zokuqhawuka:
● Ukuxinana okuphezulu. Ngokomzekelo, i-36-port ye-QDD yokuqhawula i-switch inokubonelela ngokuphindwe kathathu ukuxinwa kokutshintsha kunye ne-single-line downlink port. Ngaloo ndlela ukuphumeza inani elifanayo loqhagamshelwano usebenzisa inani elincinci lokutshintsha.
● Ukufikelela kujongano olunesantya esisezantsi. Ngokomzekelo, i-transceiver ye-QSFP-4X10G-LR-S yenza ukuba utshintsho kunye neechweba ze-QSFP kuphela zidibanise i-4x 10G LR i-interfaces nganye kwi-port.
● Ulondolozo Lwezoqoqosho. Ngenxa yesidingo esincinci sezixhobo eziqhelekileyo kubandakanya i-chassis, amakhadi, ababoneleli bamandla, abalandeli, ...
Ububi bokuqhawuka:
● Isicwangciso esinzima ngakumbi sokutshintsha. Xa enye yezibuko kwi-transceiver yokuqhawula, i-AOC okanye i-DAC, ihamba kakubi, idinga ukutshintshwa kwe-transceiver yonke okanye ikhebula.
● Akunakwenzeka ukuba uzenzele. Kutshintshiselwano nge-down-layini enye, izibuko ngalinye libumbeke ngokwalo. Ngokomzekelo, i-port nganye ingaba yi-10G, i-25G, okanye i-50G kwaye inokwamkela naluphi na uhlobo lwe-transceiver, i-AOC okanye i-DAC. I-port ye-QSFP kuphela kwimodi yokuqhawula idinga indlela yobulumko yeqela, apho zonke ii-interfaces ze-transceiver okanye ikhebula ziluhlobo olufanayo.
