Kuyini i-Transceiver Module Port Breakout nokuthi kanjani nge-Network Packet Broker?

Intuthuko yakamuva ekuxhumekeni kwenethiwekhi kusetshenziswa imodi yokuphumula iya ngokuya ibaluleke njengoba amachweba amasha anesivinini esikhulu etholakala kumaswishi, ama-router,Amathephu Enethiwekhi, Abathengisi Bephakethe Lenethiwekhikanye neminye imishini yokuxhumana. Ama-breakout avumela la ma-port amasha ukuthi axhumane nama-port anesivinini esiphansi. Ama-breakout avumela ukuxhumana phakathi kwamadivayisi enethiwekhi anezimbobo zesivinini ezahlukene, kuyilapho esebenzisa ngokugcwele i-bandwidth ye-port. Imodi yokuphuma kumishini yenethiwekhi (amaswishi, ama-router, namaseva) ivula izindlela ezintsha zabasebenzi benethiwekhi zokuhambisana nesivinini sokufunwa kwe-bandwidth. Ngokungeza ama-port anesivinini esikhulu asekela ukuphuma, abasebenzi bangandisa ubuningi be-port ye-faceplate futhi banike amandla ukuthuthukiswa kumazinga aphezulu edatha kancane kancane.

KuyiniImojuli ye-TransceiverUkuqhekeka Kwechweba?

Ukuqhekeka Kwechwebakuyindlela evumela isikhombikubona esisodwa esibonakalayo esine-bandwidth ephezulu ukuthi sihlukaniswe sibe yizikhombikubona eziningi ezizimele ezine-bandwidth ephansi ukuze kwandiswe ukuguquguquka kwenethiwekhi yenethiwekhi futhi kuncishiswe izindleko. Le ndlela isetshenziswa kakhulu kumadivayisi enethiwekhi afana nama-switch, ama-router,Amathephu EnethiwekhifuthiAbathengisi Bephakethe Lenethiwekhi, lapho isimo esivame kakhulu ukuhlukanisa isixhumi esibonakalayo se-100GE (100 Gigabit Ethernet) sibe yizixhumi eziningi ze-‌25GE (25 Gigabit Ethernet) noma i-‌10GE (10 Gigabit Ethernet). Nazi ezinye izibonelo nezici ezithile:
​
->Kudivayisi ye-‌Mylinking™ Network Packet Broker(NPB), njenge-NPB yeI-ML-NPB-3210+, isixhumi esibonakalayo se-100GE singahlukaniswa sibe yizixhumi ezine ze-25GE, kanti isixhumi esibonakalayo se-40GE singahlukaniswa sibe yizixhumi ezine ze-10GE. Le ndlela yokuvula imbobo iwusizo kakhulu ezimweni zokuxhumana ezilandelanayo, lapho lezi zixhumi ezisebenzisana ne-bandwidth ephansi zingaxhunyaniswa nezixhumi zazo zedivayisi yokugcina ngokusebenzisa ubude obufanele bekhebula.

->Ngaphezu kwemishini ye-Mylinking™ Network Packet Broker (NPB), eminye imikhiqizo yemishini yenethiwekhi nayo isekela ubuchwepheshe obufanayo bokuhlukanisa i-interface. Isibonelo, amanye amadivayisi asekela ukuhlukaniswa kwe-interface ye-100GE ibe yi-interface ye-10GE eyi-10 noma i-interface ye-4 ye-25GE. Lokhu kuguquguquka kuvumela abasebenzisi ukuthi bakhethe uhlobo lwe-interface olufanele kakhulu lokuxhumeka ngokwezidingo zabo.

->I-Port Breakout ayigcini nje ngokwandisa ukuguquguquka kwenethiwekhi, kodwa futhi ivumela abasebenzisi ukuthi bakhethe inani elifanele lamamojula esibonakalayo esinomkhawulokudonsa ophansi ngokwezidingo zabo zangempela, ngaleyo ndlela kunciphisa izindleko zokuthenga.
->Uma wenza i-Port Breakout, kubalulekile ukunaka izidingo zokuhambisana kanye nokucushwa kwamadivayisi. Isibonelo, amanye amadivayisi angadinga ukulungisa kabusha amasevisi ngaphansi kwesixhumi esibonakalayo esihlukanisiwe ngemuva kokuthuthukisa i-firmware yawo ukuze agweme ukuphazamiseka kwethrafikhi.

Ngokuvamile, ubuchwepheshe bokuhlukaniswa kwamachweba buthuthukisa ukuzivumelanisa nezimo kanye nokusebenza kahle kwemishini yenethiwekhi ngokuhlukanisa ama-interface e-bandwidth ephezulu abe ama-interface amaningi e-bandwidth ephansi, okuyindlela ejwayelekile yobuchwepheshe ekwakhiweni kwenethiwekhi yesimanje. Kulezi zindawo, imishini yenethiwekhi, njengezinguquko nama-router, ivame ukuba nenani elilinganiselwe lamachweba e-transceiver asheshayo, njenge-SFP (Small Form-Factor Pluggable), SFP+, QSFP (Quad Small Form-Factor Pluggable), noma amachweba e-QSFP+. Lawa machweba aklanyelwe ukwamukela amamojula e-transceiver akhethekile avumela ukudluliswa kwedatha okusheshayo ngezintambo ze-fiber optic noma zethusi.

I-Transceiver Module Port Breakout ikuvumela ukuthi wandise inani lama-transceiver port atholakalayo ngokuxhuma i-port eyodwa kuma-breakout port amaningi. Lokhu kuwusizo kakhulu uma usebenza ne-Network Packet Broker (NPB) noma ikhambi lokuqapha inethiwekhi.

 

IngabeUkuqhekeka Kwembobo Ye-Transceiver Moduleitholakala njalo?

Ukuqhuma kuhlale kuhilela ukuxhumeka kwechweba elinomzila oqondile kumachweba amaningi angakahleleki noma aneziteshi. Amachweba aneziteshi ahlala esetshenziswa ezintweni zefomu lemizila eminingi, njenge-QSFP+, QSFP28, QSFP56, QSFP28-DD, kanye ne-QSFP56-DD. Ngokuvamile, amachweba angakahleleki asetshenziswa ezintweni zefomu lesiteshi esisodwa, okuhlanganisa i-SFP+, SFP28, kanye ne-SFP56 yesikhathi esizayo. Ezinye izinhlobo zechweba, njenge-QSFP28, zingaba kuzo zombili izinhlangothi zokuphuma, kuye ngesimo.

Namuhla, amachweba aneziteshi afaka phakathi i-40G, 100G, 200G, 2x100G, kanye ne-400G kanti amachweba anganaziteshi afaka phakathi i-10G, 25G, 50G, kanye ne-100G njengoba kuboniswe kulokhu okulandelayo:

Ama-Transceiver Akwazi Ukuqhuma

Indlela i-Transceiver Module Port Breakout engasetshenziswa ngayo ne-Umthengisi Wephakethe Lenethiwekhi?

1. Ukuxhumeka kumadivayisi enethiwekhi:

~ I-NPB ixhunywe kwingqalasizinda yenethiwekhi, ngokuvamile ngamachweba e-transceiver asheshayo kumaswishi enethiwekhi noma kuma-router.

~ Kusetshenziswa i-Transceiver Module Port Breakout, i-transceiver port eyodwa kudivayisi yenethiwekhi ingaxhunywa kuma-port amaningi ku-NPB, okuvumela i-NPB ukuthi ithole ithrafikhi evela emithonjeni eminingi.

2. Ukwanda kwamandla okuqapha nokuhlaziya:

~ Amachweba okuqhuma ku-NPB angaxhunywa kumathuluzi ahlukahlukene okuqapha nokuhlaziya, njengama-network taps, ama-network probe, noma izinto zokuphepha.

~ Lokhu kwenza i-NPB ikwazi ukusabalalisa ithrafikhi yenethiwekhi kumathuluzi amaningi ngasikhathi sinye, okuthuthukisa amakhono okuqapha nokuhlaziya jikelele.

3. Ukuhlanganiswa kwethrafikhi okuguquguqukayo kanye nokusatshalaliswa kwayo:

~ I-NPB ingahlanganisa ithrafikhi evela kuzixhumanisi noma kumadivayisi amaningi isebenzisa ama-breakout port.

~ Ingabe isabalalisa ithrafikhi ehlanganisiwe kumathuluzi okuqapha noma okuhlaziya afanele, ithuthukise ukusetshenziswa kwala mathuluzi futhi iqinisekise ukuthi idatha efanele ihanjiswa ezindaweni ezifanele.

4. Ukungasebenzi kabusha kanye nokwehluleka:

~ Kwezinye izimo, i-Transceiver Module Port Breakout ingasetshenziswa ukuhlinzeka ngamakhono okuphindaphinda kanye nokwehluleka.

~ Uma enye yezimbobo zokuphuma ihlangabezana nenkinga, i-NPB ingaqondisa ithrafikhi kwenye imbobo etholakalayo, iqinisekise ukuqapha nokuhlaziya okuqhubekayo.

 

Ngokusebenzisa i-Transceiver Module Port Breakout ne-Network Packet Broker, abaphathi benethiwekhi namaqembu okuphepha bangakhulisa ngempumelelo amakhono abo okuqapha nokuhlaziya, bathuthukise ukusetshenziswa kwamathuluzi abo, futhi bathuthukise ukubonakala nokulawula okuphelele kwengqalasizinda yenethiwekhi yabo.
