Yintoni iTransceiver Module Port Breakout kwaye ungayenza njani ngeNetwork Packet Broker?

Inkqubela phambili yakutshanje kunxibelelwano lwenethiwekhi kusetyenziswa imo yokuphumla iya ibaluleke ngakumbi njengoko iiports ezintsha ezinesantya esiphezulu zifumaneka kwiiswitshi, ii-routers,IiTaps zeNethiwekhi, Abathengisi beePakethi zeNethiwekhikunye nezinye izixhobo zonxibelelwano. Ukusasazwa kwezixhobo kuvumela la mazibuko matsha ukuba adibane namazibuko anesantya esiphantsi. Ukusasazwa kwezixhobo kuvumela unxibelelwano phakathi kwezixhobo zenethiwekhi ezinezibuko ezahlukeneyo zesantya, ngelixa kusetyenziswa ngokupheleleyo i-bandwidth yezibuko. Imo yokusasazeka kwezixhobo zenethiwekhi (iiswitshi, ii-routers, kunye neeseva) ivula iindlela ezintsha zokuba abaqhubi benethiwekhi bahambisane nesantya semfuno ye-bandwidth. Ngokongeza amazibuko anesantya esiphezulu axhasa ukuphuma kwezixhobo, abaqhubi banokunyusa uxinano lwezibuko ze-faceplate kwaye bavumele ukuphuculwa ukuya kumazinga aphezulu edatha ngokuthe ngcembe.

Yintoni iImodyuli yeTransceiverUkuqhuma kwePort?

Ukuqhekeka kwePortyindlela evumela ukuba ujongano olunye oluphezulu lwe-bandwidth lwahlulwe lube zii-interfaces ezininzi ezizimeleyo ze-bandwidth ephantsi ukwandisa ukuguquguquka kwenethiwekhi kunye nokunciphisa iindleko. Le ndlela isetyenziswa kakhulu kwizixhobo zenethiwekhi ezifana ne-‌switches, ‌routers,IiTaps zeNethiwekhikwayeAbathengisi beePakethi zeNethiwekhi, apho imeko eqhelekileyo kukwahlulahlula i-interface ye-100GE (100 Gigabit Ethernet) ibe yi-interfaces ezininzi ze-‌25GE (25 Gigabit Ethernet) okanye i-‌10GE (10 Gigabit Ethernet). Nazi ezinye zemizekelo kunye neempawu ezithile:
​
->Kwisixhobo seMylinking™ Network Packet Broker(NPB), esifana neNPB yeML-NPB-3210+, ujongano lwe-100GE lunokwahlulwa lube zii-interfaces ezine ze-25GE, kwaye ujongano lwe-40GE lunokwahlulwa lube zii-interfaces ezine ze-10GE. Le patheni yokuqhekeka kwezibuko iluncedo kakhulu kwiimeko zonxibelelwano oluhambelanayo, apho ezi interfaces ze-bandwidth ephantsi zinokudityaniswa nee-counterparts zazo zesixhobo sokugcina ngokusebenzisa ubude obufanelekileyo bekhebula.

->Ukongeza kwizixhobo zeMylinking™ Network Packet Broker (NPB), ezinye iimpawu zezixhobo zenethiwekhi zikwaxhasa itekhnoloji efanayo yokwahlulahlula i-interface. Umzekelo, ezinye izixhobo zixhasa ukuqhekeka kwe-100GE interfaces zibe yi-10 10GE interfaces okanye i-4 25GE interfaces. Olu kuguquguquka luvumela abasebenzisi ukuba bakhethe uhlobo lwe-interface olufanelekileyo loqhagamshelo ngokweemfuno zabo.

->I-Port Breakout ayikhulisi nje kuphela ukuguquguquka kwenethiwekhi, kodwa ikwavumela abasebenzisi ukuba bakhethe inani elifanelekileyo leemodyuli zojongano lwe-bandwidth ephantsi ngokweemfuno zabo zokwenyani, ngaloo ndlela kunciphisa iindleko zokufumana.
->Xa usenza iPort Breakout, kuyimfuneko ukuqaphela iimfuno zokuhambelana kunye noqwalaselo lwezixhobo. Umzekelo, ezinye izixhobo zinokufuna ukulungelelanisa kwakhona iinkonzo phantsi kwe-split interface emva kokuphucula i-firmware yazo ukuze kuthintelwe ukuphazamiseka kwethrafikhi.

Ngokubanzi, iteknoloji yokwahlulahlula iiports iphucula ukulungelelaniswa kunye nokusebenza kakuhle kwezixhobo zenethiwekhi ngokwahlulahlula ii-high-bandwidth interfaces zibe zii-low-bandwidth interfaces ezininzi, nto leyo eyindlela eqhelekileyo yobugcisa kulwakhiwo lwenethiwekhi yanamhlanje. Kwezi meko, izixhobo zenethiwekhi, ezifana neeswitshi kunye nee-routers, zihlala zinenani elilinganiselweyo lee-high-speed transceiver ports, ezifana ne-SFP (Small Form-Factor Pluggable), i-SFP+, i-QSFP (Quad Small Form-Factor Pluggable), okanye ii-QSFP+. Ezi ports zenzelwe ukwamkela iimodyuli ze-transceiver ezikhethekileyo ezivumela ukuhanjiswa kwedatha ngesantya esiphezulu kwiintambo ze-fiber optic okanye ze-copper.

I-Transceiver Module Port Breakout ikuvumela ukuba wandise inani lee-transceiver ports ezikhoyo ngokuqhagamshela i-port enye kwii-breakout ports ezininzi. Oku kuluncedo ngakumbi xa usebenza ne-Network Packet Broker (NPB) okanye isisombululo sokujonga inethiwekhi.

 

NgabaUkuqhambuka kwePort yeModule yeTransceiverifumaneka rhoqo?

Ukuqhambuka kusoloko kubandakanya uqhagamshelo lwezibuko ezijikelezileyo kwiizibuko ezininzi ezingajikelezileyo okanye ezijikelezileyo. Iizibuko ezijikelezileyo zihlala zisetyenziswa kwiinkalo zeendlela ezininzi, ezifana ne-QSFP+, QSFP28, QSFP56, QSFP28-DD, kunye ne-QSFP56-DD. Ngokwesiqhelo, iizibuko ezingajikelezileyo zisetyenziswa kwiinkalo zeendlela enye, kuquka i-SFP+, SFP28, kunye ne-SFP56 yexesha elizayo. Ezinye iintlobo zeezibuko, ezifana ne-QSFP28, zinokuba macala omabini okuqhambuka, kuxhomekeke kwimeko.

Namhlanje, ii-channeled ports ziquka i-40G, i-100G, i-200G, i-2x100G, kunye ne-400G kwaye ii-unchanneled ports ziquka i-10G, i-25G, i-50G, kunye ne-100G njengoko kubonisiwe koku kulandelayo:
