About the NVIDIA Spectrum SN4600 - 400GbE
NVIDIA Spectrum SN4600 (SN4600C-4S) delivers sub-microsecond cut-through forwarding architecture at 38.1 billion packets per second, eliminating store-and-forward latency penalties in high-speed fabric deployments. This 1U rack-mount switch combines 64 × 400GbE QSFP-DD ports with 51.2 Tbps total switching capacity, powered by the NVIDIA Spectrum-3 ASIC—purpose-built for hyperscale data centers, HPC clusters, and AI training infrastructure where microsecond-level latency directly impacts performance outcomes.
The SN4600C-4S offers flexible port breakout to 4×100GbE, 2×200GbE, 8×50GbE, or 4×25GbE per port, enabling network architects to scale beyond 400GbE without hardware replacement. Native support for VXLAN, EVPN, RoCE v2, and MLAG on NVIDIA Cumulus Linux or Onyx OS simplifies convergence of compute and storage fabrics. Redundant hot-swappable power supplies and fan modules ensure five-nines availability in mission-critical environments. The 64 MB packet buffer and sub-microsecond latency make this switch ideal for real-time analytics, GPU cluster interconnects, and low-latency trading platforms where jitter cannot be tolerated. Network engineers and AI infrastructure teams select this platform to future-proof multi-year fabric roadmaps while maintaining deterministic performance across thousands of concurrent flows.
