NVIDIA Spectrum SN3000 Open Ethernet Switches

Industry-leading features, performance, scale and visibility for the data center.

SN3000 NVIDIA Mellanox

Industry-Leading Performance, Scalability, and Features

NVIDIA® Spectrum®-2 SN3000 Ethernet switches are ideal for leaf and spine data center network solutions, allowing maximum flexibility with port speeds from 1GbE to 400GbE per port and port density that enables full-rack connectivity to any server at any speed. SN3000 carries a whopping bidirectional switching capacity of up to 12.8Tb/s with a landmark 8.33Bpps packet processing rate. Purpose-built for the modern data center, SN3000 combines high performance, rich features, scalability, and visibility with flexible form factors.

NVIDIA Spectrum SN3000 switches support detailed and contextual telemetry with NVIDIA What Just Happened® (WJH). WJH dramatically reduces mean time to issue resolution by providing instant answers to when, what, who, where and why questions as soon as an issue occurs. Spectrum switches implement hardware- accelerated histograms track and summarize queue depths at a sub-microsecond granularity. Hardware-accelerated histograms avoid false-alerts common to simple watermarks and threshold based methods.



NVIDIA Spectrum SN3000 switches feature a fully shared packet and monolithic buffer architecture. This superior buffer architecture provides a fair, predictable and high-performance data path that is essential for scale out software defined storage and modern multi-tenant cloud deployments. Spectrum switches deliver a robust high bandwidth and low latency data path for remote direct-memory access over converged Ethernet (RoCE) and machine learning applications that leverage GPUDdirect®.



NVIDIA Spectrum SN3000 switches support best-in-class Virtual Extensible LAN (VXLAN) with support for 10X more tunnels and tunnel end points. Its 512K shared forwarding entries can be flexibly used across access-control lists (ACL), longest prefix match (LPM) routes, host routes, MAC tables, and equal-cost multi-path (ECMP) and tunnel applications.
