NVIDIA Spectrum-4 SN5400 Layer 3 Switch
The SN5400 smart-leaf, spine, and super-spine switch offers 64 ports of 400 gigabit Ethernet (GbE) in a 2U form factor. The SN5400 offers diverse quad small form factor double density (QSFP-DD) connectivity in combinations from 1 to 400GbE and boasts a total throughput of 25.6Tb/s, making it ideal for 400G data center fabrics.
NVIDIA Spectrum SN5000 (SN5400) switch resources
The NVIDIA Spectrum SN5000 Series represents the fifth generation of NVIDIA’s Spectrum Ethernet switch platforms, engineered to deliver accelerated, predictable, and highly scalable Ethernet networking for modern data‑center fabrics, hyperscale cloud environments, AI/ML clusters, and enterprise networks. These switch systems are built around the NVIDIA Spectrum‑4 ASIC, combining ultra‑high throughput, deep shared buffering, open networking flexibility, and advanced telemetry to meet the demanding performance and feature requirements of today’s large‑scale infrastructure deployments.
Accelerating data center fabrics with 400GbE density
The SN5400 delivers high-density 400 GbE switching — with 64 × QSFP-DD ports plus 2 × 25 GbE SFP28 — ideal for spine/leaf, super-spine, AI/HPC, and cloud-scale network fabrics requiring massive bandwidth, low latency, and flexible breakout configurations from 1 to 400 Gb/s per port. :contentReference[oaicite:2]{index=2}
Scalable, high-throughput architecture
SN5400 supports up to 25.6 Tb/s switching capacity, wire-speed Layer 2/3 forwarding, and a broad spectrum of speeds from 10 Gb/s to 400 Gb/s per port. It supports breakout configurations — scaling to hundreds of lower-speed ports if needed — while maintaining consistent performance and predictable latency for demanding applications. :contentReference[oaicite:3]{index=3}
High availability and flexible, open-networking deployment
The SN5400 is engineered for nonstop operation — with dual hot-swappable power supplies, redundant fans, N+1 cooling, and support for breakout and multi-speed configurations. With support for open-networking OS like Cumulus Linux and SONiC via ONIE, it enables vendor-neutral, programmable, and flexible data center fabrics. :contentReference[oaicite:4]{index=4}
