About the NVIDIA Spectrum SN3100
The NVIDIA Spectrum SN3100 (part number SN3100-4S) delivers 32 ports of 100GbE QSFP28 connectivity in a compact 1U form factor, with flexible breakout support enabling 4 × 25GbE or 4 × 10GbE configurations per port. Built on the NVIDIA Spectrum-1 ASIC, this switch achieves 6.4 Tbps switching capacity and forwards traffic at up to 4.76 billion packets per second with sub-microsecond cut-through latency. The 16 MB shared packet buffer, dual redundant hot-swappable power supplies, and hot-swappable fan modules ensure carrier-grade reliability, while typical power consumption of just 200W keeps operational costs minimal in dense deployment scenarios.
Data center network engineers and AI infrastructure teams select the SN3100-4S to consolidate high-speed fabric connectivity without sacrificing performance or manageability. The switch supports industry-standard routing protocols including BGP, OSPF, and ECMP, plus overlay technologies such as VXLAN and EVPN for modern cloud and containerized workloads. IT procurement and network operations teams value its compatibility with both NVIDIA Onyx NOS and Cumulus Linux, enabling choice in operating system strategy. Advanced features—port-side airflow options, out-of-band 1GbE management, and comprehensive QoS capabilities (PFC, ECN, LLDP, sFlow)—make this switch ideal for hyperscale environments, HPC clusters, and enterprise data centers requiring deterministic, low-latency connectivity.
