About the NVIDIA Spectrum SN3200
The NVIDIA Spectrum SN3200 delivers sub-microsecond cut-through latency, eliminating the store-and-forward delays that constrain legacy switching architectures. Built on the NVIDIA Spectrum-2 ASIC, this 1U rack-mount switch processes traffic at 8.33 Bpps with a switching capacity of 12.8 Tbps, setting the performance standard for hyperscale and high-frequency trading environments. The SN3200-4S features 32 ports of native 400GbE per port, with flexible breakout support enabling 64×200GbE, 128×100GbE, 256×50GbE, or 128×25GbE configurations via breakout cables. Redundant hot-swap power supplies and dual airflow options—port-side exhaust and port-side intake—ensure deployment flexibility across diverse data center topologies. Management is handled via 1×10/100/1000BASE-T out-of-band port and 1×USB connection.
Network architects and AI infrastructure teams standardize on NVIDIA switching when lossless Ethernet and sub-microsecond forwarding become non-negotiable. The SN3200-4S enforces RoCEv2 with ECN and PFC at the hardware level, critical for RDMA-intensive workloads and machine learning clusters. NVIDIA Onyx (MLNX-OS), SONiC, and Cumulus Linux support ensure choice in network operating systems. Layer 2 capabilities span VXLAN, EVPN, STP/RSTP/MSTP, LACP, and QinQ, while Layer 3 includes BGP, OSPF, IS-IS, ECMP, BFD, VRF, and PIM. Advanced telemetry—NVIDIA What Just Happened (WJH), gNMI/OpenConfig, sFlow, and SNMP—delivers visibility into packet loss and fabric congestion without sacrificing performance.
Operating across 0°C to 45°C, the SN3200-4S integrates into mission-critical environments from cloud service providers to research institutions.
