About the NVIDIA Spectrum SN4700 - 400GbE
The NVIDIA Spectrum SN4700 - 400GbE (part number SN4700-2S) delivers 32 ports of 400GbE connectivity in a compact 2U form factor, enabling massive port density and unmatched switching capacity for hyperscale data centers and high-performance computing environments. With the ability to break out individual 400GbE ports into up to 128 x 100GbE or 256 x 50GbE configurations via QSFP-DD breakout, this switch provides unparalleled flexibility for network architects seeking to future-proof their infrastructure investments.
Built on the NVIDIA Spectrum-3 ASIC, the SN4700-2S combines a total switching capacity of 12.8 Tbps with a forwarding rate of up to 8.33 Bpps and sub-microsecond cut-through switching latency, making it ideal for latency-sensitive workloads and real-time data movement. Network engineers and infrastructure teams benefit from comprehensive protocol support including BGP, OSPF, ECMP, VXLAN, EVPN, RoCEv2, and PFC/ETS/DCBX, alongside advanced telemetry via NVIDIA What Just Happened (WJH), sFlow, SNMP, and streaming telemetry. The switch runs NVIDIA Cumulus Linux or NVIDIA Onyx, offering choice in network operating systems. Redundant, hot-swappable power supplies and fan modules ensure high availability, while out-of-band 1GbE management and USB Type-A ports support operational flexibility across 0°C to 45°C environments.
