Iyini i-Transceiver Module Port Breakout futhi kanjani nge-Network Packet Broker?

Intuthuko yakamuva ekuxhumekeni kwenethiwekhi kusetshenziswa imodi yokuphuma iya ngokuya ibaluleka njengoba izimbobo ezintsha ezinesivinini esikhulu zitholakala kumaswishi, amarutha,I-Network Taps, I-Network Packet Brokersnezinye izinto zokuxhumana. Ama-breakout avumela lezi zimbobo ezintsha ukuthi zihlangane nezimbobo ezinesivinini esiphansi. 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.

YiniI-Transceiver ModuleI-Port Breakout?

I-Port Breakoutkuyindlela evumela isixhumi esibonakalayo esisodwa somkhawulokudonsa ophezulu ukuthi sihlukaniseke sibe yizindawo ezizimele eziningi ezinomkhawulokudonsa omncane ukuze kwandiswe ukuguquguquka kwenethiwekhi nokunciphisa izindleko. Le nqubo isetshenziswa kakhulu kumadivayisi enethiwekhi afana nokushintsha, ama-routers,I-Network TapsfuthiI-Network Packet Brokers, lapho isimo esivame kakhulu siwukuhlukanisa isixhumi esibonakalayo esingu-100GE (100 Gigabit Ethernet) sibe yizingosi zokuxhumana eziningi ezingu-25GE (25 Gigabit Ethernet) noma 10GE (10 Gigabit Ethernet). Nazi izibonelo ezithile nezici:
.
->Kudivayisi yeMylinking™ Network Packet Broker(NPB), njenge-NPB yeI-ML-NPB-3210+, i-interface ye-100GE ingahlukaniswa ibe yizindawo ezine ze-25GE, futhi isixhumi esibonakalayo se-40GE singahlukaniswa sibe yizindawo ezine ze-10GE. Le phethini yokuphuma kwembobo iwusizo kakhulu kuzimo zenethiwekhi ze-hierarchical, lapho lezi zixhumanisi zomkhawulokudonsa ophansi zingaphambaniswa nozakwabo bedivayisi yesitoreji ngokusebenzisa ubude obufanele bekhebuli. .

->Ngokungeziwe kumishini ye-Mylinking™ Network Packet Broker(NPB), ezinye izinhlobo zezinto zenethiwekhi nazo zisekela ubuchwepheshe obufanayo bokuhlukanisa isixhumi esibonakalayo. Isibonelo, amanye amadivayisi asekela ukuxhumana kwe-breakout kwe-100GE ibe yi-10 10GE interface noma 4 25GE interface. Lokhu kuvumelana nezimo kuvumela abasebenzisi ukuthi bakhethe uhlobo lwesixhumi esibonakalayo olufanele kakhulu ukuze baxhumeke ngokwezidingo zabo. .

->I-Port Breakout ayikhulisi nje kuphela ukuguquguquka kwenethiwekhi, kodwa futhi ivumela abasebenzisi ukuthi bakhethe inombolo efanelekile yamamojula we-interface yomkhawulokudonsa ophansi ngokwezidingo zabo zangempela, ngaleyo ndlela banciphise izindleko zokuthola. .
->Lapho wenza i-Port Breakout, kuyadingeka ukuthi unake izidingo zokuhambisana nokucushwa kwamadivayisi. Isibonelo, amanye amadivayisi angase adinge ukulungisa kabusha amasevisi ngaphansi kwesixhumi esibonakalayo esihlukanisiwe ngemva kokuthuthukisa i-firmware yawo ukuze agweme ukuphazamiseka kwethrafikhi. .

Ngokuvamile, ubuchwepheshe bokuhlukanisa ichweba buthuthukisa ukuguquguquka kanye nokusebenza kahle kwezindleko zemishini yenethiwekhi ngokuhlukanisa izixhumi ezibonakalayo ezinomkhawulokudonsa ophezulu zibe yizindawo eziningi eziphansi zomkhawulokudonsa, okuyindlela yobuchwepheshe evamile ekwakhiweni kwenethiwekhi yesimanje. Kulezi zindawo, okokusebenza kwenethiwekhi, okufana namaswishi namarutha, kuvame ukuba nenani elilinganiselwe lamachweba we-transceiver anesivinini esikhulu, njenge-SFP (Small Form-Factor Pluggable), SFP+, QSFP (Quad Small Form-Factor Pluggable), noma QSFP+ amachweba. Lawa machweba aklanyelwe ukwamukela amamojula akhethekile e-transceiver anika amandla ukudluliswa kwedatha ngesivinini esiphezulu ngezintambo ze-fiber optic noma zethusi.

I-Transceiver Module Port Breakout ikuvumela ukuthi unwebe inombolo yezimbobo ze-transceiver ezitholakalayo ngokuxhuma imbobo eyodwa kuzimbobo zokuphuma eziningi. Lokhu kubaluleke kakhulu uma usebenza ne-Network Packet Broker (NPB) noma isixazululo sokuqapha inethiwekhi.

 

IngabeI-Transceiver Module Port Breakoutitholakala njalo?

I-Breakout ihlale ihilela ukuxhumeka kwembobo enesiteshi kumachweba amaningi angashaneli noma aneziteshi. Izimbobo zamashaneli zihlale zisetshenziswa ngezindlela zamafomu amaningi, njenge-QSFP+, QSFP28, QSFP56, QSFP28-DD, ne-QSFP56-DD. Ngokuvamile, amachweba angashaneli asetshenziswa ngezindlela zefomu lesiteshi esisodwa, okuhlanganisa i-SFP+, i-SFP28, ne-SFP56 yesikhathi esizayo. Ezinye izinhlobo zamachweba, njenge-QSFP28, zingaba nhlangothi zombili zokuqhuma, kuye ngesimo.

Namuhla, izimbobo ezineziteshi zifaka i-40G, 100G, 200G, 2x100G, ne-400G kanye nezimbobo ezingenasiteshi zifaka i-10G, 25G, 50G, kanye ne-100G njengoba kukhonjisiwe kulokhu okulandelayo:

I-Transceiver Module Port Breakout ingasetshenziswa kanjani ngeI-Network Packet Broker?

1. Ukuxhumeka kumadivayisi enethiwekhi:

~ I-NPB ixhunywe nengqalasizinda yenethiwekhi, ngokuvamile ngezimbobo ze-transceiver ezinesivinini esikhulu kumaswishi enethiwekhi noma amarutha.

~ Ngokusebenzisa i-Transceiver Module Port Breakout, imbobo ye-transceiver eyodwa kudivayisi yenethiwekhi ingaxhunywa kumachweba amaningi ku-NPB, okuvumela i-NPB ukuthi ithole ithrafikhi evela emithonjeni eminingi.

2. Ukwenyuka kwamandla okuqapha nokuhlaziya:

~ Izimbobo zokuphuma ku-NPB zingaxhunywa kumathuluzi ahlukahlukene okuqapha nokuhlaziya, afana nompompi benethiwekhi, ama-probe enethiwekhi, noma izinto zikagesi zokuphepha.

~ Lokhu kuvumela i-NPB ukuthi isabalalise ithrafikhi yenethiwekhi kumathuluzi amaningi ngesikhathi esisodwa, ithuthukise amakhono okuqapha nokuhlaziya esewonke.

3. Ukuhlanganiswa nokusatshalaliswa kwethrafikhi okuguquguqukayo:

~ I-NPB ingahlanganisa ithrafikhi kusuka kuzixhumanisi eziningi zenethiwekhi noma amadivayisi isebenzisa izimbobo zokuphuma.

~ Ingakwazi ke ukusabalalisa ithrafikhi ehlanganisiwe kumathuluzi afanele okuqapha noma okuhlaziya, ithuthukise ukusetshenziswa kwalawa mathuluzi futhi iqinisekise ukuthi idatha efanelekile ilethwa ezindaweni ezifanele.

4. Ukuphelelwa umsebenzi kanye nokuhluleka:

~ Kwezinye izimo, i-Transceiver Module Port Breakout ingase isetshenziselwe ukunikeza amandla okuphinda futhi ahluleke.

~ Uma elinye lamachweba aphumayo lihlangabezana nenkinga, i-NPB ingaqondisa kabusha ithrafikhi kwenye indawo etholakalayo, iqinisekise ukuqapha nokuhlaziya okuqhubekayo.

 

Ngokusebenzisa i-Transceiver Module Port Breakout nge-Network Packet Broker, abaphathi benethiwekhi namaqembu ezokuphepha bangakala ngempumelelo amakhono abo okuqapha nokuhlaziya, bathuthukise ukusetshenziswa kwamathuluzi abo, futhi bathuthukise ukubonakala nokulawula ingqalasizinda yabo yenethiwekhi.
