Ngomhla we-19 kuMatshi, ngo-2021
Kwiminyaka emihlanu ukuya kwesixhenxe edlulileyo isantya esiqhelekileyo soxhumo phakathi kwe-Top of Rack (ToR) iqabunga elitshintshileyo kwi-subtending computer kunye neeseva zokugcina zibe yi-10Gbps.Amaziko amaninzi edatha ye-hyperscale kunye namaziko amakhulu edatha yamashishini afuduka la makhonkco okufikelela kwi-25Gbps.Olu nxibelelwano lunokwakhiwa kusetyenziswa i-25Gbps Direct Attached Copper cables (DACs), Active Optical Cables (AOCs), okanye nge-pair of SFP28 25Gbps transceivers optical kunye ne-duplex fibre optic jumper cable efanelekileyo.
Ukubonisa esi sicelo kunye neemveliso zelizwe lokwenyani, iswitshi yeToR evela kuthotho lweCisco's Nexus 3000 kunye neseva exhonywe kwi-rack evela kwi-Supermicro ikhethiwe.Kuphela ezinye iziqwenga ezifunekayo ziFiberconcepts SFP-25G-SR-s multimode transceivers kunye neOM4 multimode patch cables.
UKUTSHINTSHA KWEQHACA: CiscoI-Nexus 34180YC
Iqonga le-Nexus 3400 liyinxalenye yesizukulwana samva nje se-Nexus®3000 Series Switshi ezisisigxina.Uluhlu lwe-3000 lujoliswe ngokulinganayo kwizicelo zeToR.Onke amalungu compact (1RU) uqwalaselo esisigxina iimveliso.Kuyo yonke le ntsapho yeemveliso ngokuqinisekileyo zonke iireyithi ezifumanekayo ze-optical ethernet ziyanikezelwa, ukusuka kwi-1G ukuya kwi-400G.
I-Nexus 34180YC iyitshintshi efanelekileyo yokubonisa ukusetyenziswa kwe-INTCERA brand, i-Cisco ehambelana ne-SFP-25G-SR-S i-transceiver.Olu tshintsho lunikeza ukuguquguquka okukhulu kwizantya zamachweba, ezigubungela i-1G, i-10G, i-25G, i-40G kunye ne-100G amazinga.I-34180YC iyacwangciswa ivumela umsebenzisi kubathengi ukuba balungele indlela yokuhambisa ipakethi kwiimfuno zezicelo zabo.Umzekelo, izicelo zokurhweba ngesantya esiphezulu zezemali zinokuphuculwa kweyona latency isezantsi enokwenzeka.Olu tshintsho luxhotyiswe nge-48 SFP +/SFP28 port (1G/10G/25G) kunye ne-6 QSFP +/QSFP28 (40G/100G) izibuko.Iswitshi ixhasa umgca ogcweleyo izinga Layer 2/3 ukutshintsha kuzo zonke ezi zibuko, iyonke 3.6 Terabits / sec kunye 1.4 Gigapackets / sec.
I-34180YC inokuxhotyiswa ngoluhlu olubanzi lweendidi ze-transceiver optical interface kuzo zonke iireyithi ezininzi ezikhankanywe ngasentla.Iitheyibhile ezingezantsi ziquka iintlobo ze-transceiver ezihambelanayo kwiindidi ezimbini zamachweba ekutshintsheni.
