About the NVIDIA Spectrum SN5000 - 400GbE
The NVIDIA Spectrum SN5000 - 400GbE (part number SN5000-2S) delivers 64 × 400GbE QSFP112 ports with a switching capacity of 51.2 Tbps and forwarding rate of 38.4 Bpps, establishing it as a high-density spine or core switch for mission-critical data center fabrics. Built on the NVIDIA Spectrum-4 ASIC, this 1U rack-mount platform supports flexible port breakout across 400GbE, 200GbE, 100GbE, 50GbE, 25GbE, and 10GbE via breakout cables, enabling heterogeneous network topologies without hardware replacement. Sub-microsecond cut-through forwarding latency combined with hardware-accelerated lossless RoCEv2, ECN, and PFC ensure deterministic performance for latency-sensitive workloads. Management integration includes redundant hot-swap power supplies, 1 × 1000BASE-T out-of-band management port, 1 × RS-232 console, and compatibility with NVIDIA Onyx NOS and NVIDIA UFM platforms.
Enterprise data center architects, network engineers, and AI infrastructure teams seeking ultra-low-latency, lossless switching for AI training clusters, HPC interconnects, and disaggregated storage fabrics are the primary buyers for this switch. The platform supports advanced routing protocols—BGP, OSPF, IS-IS, and ECMP with up to 128 next hops—alongside overlay networking via VXLAN with BGP-EVPN control plane. Eight traffic classes enable granular QoS policies, while gNMI streaming telemetry, sFlow, SNMP, and PTP IEEE 1588v2 hardware timestamping provide comprehensive observability and time synchronization across distributed systems. OpenConfig, YANG, REST API, and CLI management interfaces allow seamless integration into orchestration and automation frameworks.
Organizations requiring carrier-grade switching density, sub-microsecond latency, and NVIDIA's ecosystem support should evaluate the Spectrum SN5000 - 400GbE (SN5000-2S) for immediate deployment.
