Kwa zaka zisanu mpaka zisanu ndi ziwiri zapitazi, liwiro lodziwika bwino lolumikizana pakati pa masamba a Top of Rack (ToR) amasinthidwe kumakompyuta ndi ma seva osungira kwakhala 10Gbps.Malo ambiri a data a hyperscale komanso mabizinesi akuluakulu akusamutsa maulalo awa kupita ku 25Gbps.Zolumikizidwezi zitha kupangidwa pogwiritsa ntchito zingwe za 25Gbps Direct Attached Copper (DACs), Active Optical Cables (AOCs), kapena ndi ma transceivers owoneka bwino a SFP28 25Gbps ndi chingwe choyenera cha duplex fiber optic jumper.
Kuti muwonetse pulogalamuyi ndi zinthu zenizeni padziko lapansi, kusintha kwa ToR kuchokera ku Cisco's Nexus 3000 mndandanda ndi seva yokhala ndi rack yochokera ku Supermicro yasankhidwa.Zida zina zokhazo zomwe zimafunikira ndi Fiberconcepts SFP-25G-SR-s multimode transceivers ndi OM4 multimode patch zingwe.
TOR LEAF SITCH:CiscoNexus 34180YC
Pulatifomu ya Nexus 3400 ndi gawo la m'badwo waposachedwa kwambiri wa Nexus®3000 Series Switches.Mndandanda wa 3000 ndiwolunjika pazogwiritsa ntchito za ToR.Mamembala onse ndi compact (1RU) zokhazikika zokhazikika.Pagulu ili lazinthu zonse mitengo yomwe ilipo ya optical ethernet imaperekedwa, kuyambira 1G mpaka 400G.
Nexus 34180YC ndikusintha koyenera kuwonetsa kugwiritsidwa ntchito kwa mtundu wa INTCERA, transceiver yogwirizana ya Cisco ya SFP-25G-SR-S.Kusinthaku kumapereka kusinthasintha kwakukulu pamayendedwe amadoko, kuphimba 1G, 10G, 25G, 40G ndi 100G mitengo.The 34180YC ndi yokonzeka kulola wogwiritsa ntchito kwa makasitomala kuti asinthe machitidwe otumizira paketi malinga ndi zomwe akufuna.Mwachitsanzo, ntchito zamalonda zothamanga kwambiri zitha kukonzedwa kuti zikhale zotsika kwambiri.Kusinthaku kuli ndi madoko 48 SFP +/SFP28 (1G/10G/25G) ndi madoko 6 QSFP+/QSFP28 (40G/100G).Kusinthaku kumathandizira kuchuluka kwa mzere wa Layer 2/3 kusintha pamadoko onsewa, okwana 3.6 Terabits/sec ndi 1.4 Gigapackets/sec.
34180YC ikhoza kukhala ndi mitundu yosiyanasiyana ya mawonekedwe a transceiver optical pamitengo yambiri yomwe yatchulidwa pamwambapa.Matebulo omwe ali pansipa akuphatikiza mitundu yofananira ya ma transceiver amitundu iwiri yamadoko mu switch.
