Kwemakore mashanu kusvika manomwe apfuura iyo yakanyanya kukurumidza kukurumidza yekubatanidza pakati peTop of Rack (ToR) mashizha anochinja kune kudzora komputa uye maseva ekuchengetedza anga ari 10Gbps.Mazhinji hyperscale data centers uye kunyange makuru ebhizinesi data centers ari kutamisa aya ekuwana malink ku25Gbps.Izvi zvinongedzo zvinogona kugadzirwa uchishandisa 25Gbps Direct Attached Copper cables (DACs), Active Optical Cables (AOCs), kana nepeya yeSFP28 25Gbps transceivers optical uye yakakodzera duplex fiber optic jumper cable.
Kuratidzira ichi chishandiso chine zvigadzirwa zvepasirese, ToR switch kubva kuCisco's Nexus 3000 akatevedzana uye rack-yakaiswa server kubva kuSupermicro yakasarudzwa.Izvo chete zvimwe zvidimbu zvinodiwa Fiberconcepts SFP-25G-SR-s multimode transceivers uye OM4 multimode chigamba tambo.
TOR LEAF SHANDURA: CiscoNexus 34180YC
Iyo Nexus 3400 chikuva chikamu chechizvarwa chazvino cheiyo yakagadziriswa Nexus®3000 Series Swichi.Iyo 3000 yakatevedzana yakanangana neToR application.Nhengo dzese dziri compact (1RU) yakagadziriswa zvigadzirwa.Pakati peiyi mhuri yezvigadzirwa zvese zviripo mareti e-optical ethernet anopihwa, kubva ku1G kusvika 400G.
Iyo Nexus 34180YC ishanduko yakanaka kuratidza kushandiswa kweINTCERA brand, Cisco inoenderana SFP-25G-SR-S transceiver.Iyi switch inopa kuchinjika kukuru mukumhanya kwechiteshi, kufukidza 1G, 10G, 25G, 40G uye 100G mitengo.Iyo 34180YC inorongeka ichibvumira mushandisi kune vatengi kuti vagadzirise hunhu hwekutumira pakiti kune zvinodiwa zvekushandisa kwavo.Semuyenzaniso, kumhanyisa kwemari yekutengesa zvikumbiro zvinogona kuvandudzwa kune yakaderera inogoneka latency.Switch iyi ine 48 SFP+/SFP28 ports (1G/10G/25G) uye 6 QSFP+/QSFP28 (40G/100G) ports.Iyo switch inotsigira yakazara mutsetse chiyero Layer 2/3 switching pane ese aya madoko, anokwana 3.6 Terabits/sec uye 1.4 Gigapackets/sec.
Iyo 34180YC inogona kunge yakashongedzerwa neyakasiyana-siyana yeoptical transceiver interface marudzi pane akawanda mareti ataurwa pamusoro.Iwo matafura ari pazasi anosanganisira anowirirana transceiver marudzi ezvikamu zviviri zvezviteshi mune switch.
