Rau tsib mus rau xya xyoo dhau los qhov kev sib txuas ceev tshaj plaws ntawm Sab saum toj ntawm Rack (ToR) nplooj hloov mus rau subtending computer thiab cia servers yog 10Gbps.Ntau lub chaw cov ntaub ntawv hyperscale thiab txawm tias cov chaw lag luam loj dua cov ntaub ntawv tau hloov pauv cov kev nkag mus rau 25Gbps.Cov kev sib txuas no yuav raug tsim los siv 25Gbps Direct Attached Copper cables (DACs), Active Optical Cables (AOCs), lossis nrog ib khub ntawm SFP28 25Gbps optical transceivers thiab ib qho tsim nyog duplex fiber optic jumper cable.
Txhawm rau piav qhia daim ntawv thov no nrog cov khoom siv hauv ntiaj teb tiag tiag, ToR hloov los ntawm Cisco's Nexus 3000 series thiab khib-mounted server los ntawm Supermicro tau raug xaiv.Tsuas yog lwm daim yuav tsum yog Fiberconcepts SFP-25G-SR-s multimode transceivers thiab OM4 multimode thaj cables.
TOR LEAF SWITCH: CiscoNexus 34180 YC
Lub platform Nexus 3400 yog ib feem ntawm lub cim tshiab ntawm cov hloov kho Nexus® 3000 Series.Lub 3000 series yog squarely tsom rau cov ntawv thov ToR.Tag nrho cov tswv cuab yog compact (1RU) taag configuration khoom.Thoob plaws hauv tsev neeg ntawm cov khoom no tseem ceeb tag nrho cov nqi ntawm optical ethernet muaj, los ntawm 1G txog 400G.
Lub Nexus 34180YC yog qhov hloov pauv zoo tshaj plaws los ua kom pom kev siv ntawm INTCERA hom, Cisco tshaj SFP-25G-SR-S transceiver.Qhov kev hloov no muaj kev hloov pauv tau zoo hauv cov chaw nres nkoj nrawm, npog 1G, 10G, 25G, 40G thiab 100G tus nqi.34180YC yog programmable tso cai rau tus neeg siv rau cov neeg siv khoom los txiav cov ntawv xa mus rau tus cwj pwm rau cov kev xav tau ntawm lawv daim ntawv thov.Piv txwv li, kev kub ceev nyiaj txiag kev lag luam daim ntawv thov tuaj yeem ua kom zoo rau qhov qis tshaj qhov ua tau latency.Qhov kev hloov no tau nruab nrog 48 SFP + / SFP28 chaw nres nkoj (1G / 10G / 25G) thiab 6 QSFP + / QSFP28 (40G / 100G) chaw nres nkoj.Qhov hloov pauv txhawb nqa tag nrho cov kab nqi Txheej Txheej 2/3 hloov ntawm tag nrho cov chaw nres nkoj no, tag nrho 3.6 Terabits / sec thiab 1.4 Gigapackets / sec.
34180YC tuaj yeem nruab nrog ntau hom kev kho qhov muag transceiver interface thoob plaws ntau tus nqi hais los saum toj no.Cov lus hauv qab no suav nrog hom transceiver sib xws rau ob pawg ntawm cov chaw nres nkoj hauv qhov hloov.
