We clean up after ourselves.

The NVIDIA Mellanox SN3700 delivers next-generation 200 Gigabit switching for spine and super-spine deployments. This refurbished Spectrum-2 switch packs 32 QSFP56 ports into a 1RU form factor, delivering a massive 12.8 Tbps of non-blocking throughput for AI infrastructure, machine learning clusters, and high-density data center environments.

Powered by the advanced Spectrum-2 ASIC, the SN3700 achieves 8.33 billion packets per second with just 425 nanoseconds of latency. Deploy as a spine switch in leaf-spine architectures or as a super-spine for large-scale data center fabrics. Each QSFP56 port flexibly supports 10G, 25G, 40G, 50G, 100G, or 200G speeds, providing maximum deployment flexibility as your network grows.

Perfect for organizations building AI training clusters, GPU computing environments, NVMe over Fabrics storage networks, and hyperscale data centers that demand the highest throughput available. The SN3700's massive 12.8 Tbps capacity handles the most demanding workloads including distributed AI training, real-time analytics, and high-frequency trading applications.
