Spectrum-4-SN5400, Nvidia Ethernet Switch, Spectrum-4/SN5400

The NVIDIA Spectrum-4-SN5400 is a high-performance Ethernet switch designed for modern data center and cloud network fabrics. This 2U top-of-rack and spine-class platform delivers 64 × 400GbE ports on the front panel, powered by the NVIDIA Spectrum-4 ASIC for predictable, low-latency switching at massive scale. With flexible port split options, the Spectrum-4-SN5400 can support up to 128 × 200/400GbE or up to 256 lower-speed ports, allowing you to tailor connectivity for diverse workloads and migration paths.

For distributors and resellers in Asia, Europe, Africa, and North America, the Spectrum-4-SN5400 offers a scalable core for high-density leaf–spine designs, helping you standardize on a single, reliable 400GbE platform across different customer segments. Small and mid-sized system integrators can use this NVIDIA switch to build cloud-ready infrastructure, consolidate multiple lower-speed switches, and simplify cabling while preparing for rapid traffic growth driven by AI, analytics, and virtualization. End customers benefit from a consistent feature set and non-blocking Ethernet performance that supports demanding applications such as storage, AI training clusters, and high-throughput east–west traffic.

The fixed 2U design with 64 native 400GbE interfaces makes it easy to deploy the Spectrum-4-SN5400 as a spine in large data centers or as a high-capacity leaf for server and accelerator connectivity. The Spectrum-4 ASIC ensures deterministic forwarding and advanced telemetry capabilities, enabling tighter control and better visibility for operations teams. Its flexible port split options help organizations transition from 100GbE or 200GbE infrastructures to 400GbE without disruptive hardware changes, while still supporting a mix of speeds for legacy and next-generation devices.

Whether you are building an enterprise private cloud, scaling a public cloud region, or upgrading a research or AI cluster, the NVIDIA Spectrum-4-SN5400 delivers the dense 400GbE connectivity, efficiency, and flexibility needed for long-term growth.
