About the NVIDIA Spectrum SN1800 - 400GbE
The NVIDIA Spectrum SN1800 - 400GbE (part number SN1800-2S) is a high-performance data center switch engineered for enterprises requiring ultra-high-speed interconnectivity and lossless networking. Built on the NVIDIA Spectrum-2 ASIC, this 1U switch delivers exceptional throughput and forwarding performance for mission-critical applications. Network engineers and data center architects will find this switch ideal for building resilient, high-capacity fabric architectures that demand deterministic latency and wire-speed forwarding across hundreds of gigabits per second.
With 32 ports of 400GbE connectivity via QSFP-DD interfaces, the SN1800-2S supports up to 128 × 100GbE breakout configurations, offering unmatched flexibility for diverse deployment scenarios. NVIDIA Cumulus Linux operating system provides an open, programmable platform, while advanced features including VXLAN tunnels with EVPN control plane, RoCEv2 RDMA support, and lossless Ethernet mechanisms (PFC and ECN) ensure optimal performance for both traditional and modern workloads. Real-time visibility is delivered through NVIDIA NetQ, sFlow, and streaming telemetry capabilities. Contact Omnixon Global for a detailed Request for Quotation on the NVIDIA Spectrum SN1800 - 400GbE.
