About the NVIDIA Spectrum SN3700 - 100/400GbE
The NVIDIA Spectrum SN3700 delivers wire-speed packet forwarding through its purpose-built NVIDIA Spectrum-2 ASIC architecture, capable of sustaining up to 4.76 Bpps forwarding rate across a unified 12.8 Tbps switching fabric. This cut-through switching design eliminates unnecessary latency, making it ideal for latency-sensitive workloads in hyperscale data centers and high-performance computing environments where every microsecond counts.
Purpose-built for network engineers and data center architects managing next-generation infrastructure, the NVIDIA Spectrum SN3700 (part number SN3700V2-688C) combines exceptional port density with operational reliability. With 32 400GbE QSFP-DD ports native to the platform, or up to 128 100GbE ports via breakout capability, this 1U rack-mount switch handles massive traffic aggregation without sprawling your physical footprint. NVIDIA's Cumulus Linux and Onyx operating systems provide a choice of open or proprietary management, while robust Layer 3 routing (BGP, OSPF, IS-IS, PIM, ECMP), VXLAN with EVPN overlay support, and full RoCEv2 hardware enforcement ensure seamless integration into modern disaggregated architectures. Advanced telemetry—including in-band network telemetry, SNMP, sFlow, and gNMI/OpenConfig—delivers the observability your team needs. Redundant hot-swappable power supplies and fan modules, combined with flexible airflow options (port-to-power or power-to-port), minimize downtime. Rated for MTBF greater than 100,000 hours and operating across 0°C to 45°C, this switch meets FCC, CE, UL, and RoHS compliance standards for global deployment.
