NVIDIA Spectrum SN4000 Open Ethernet Switches

Cloud, storage, and AI interconnects with visibility at scale.

REQUEST AN EVALUATION

Optimize Utilization and Efficiency with Cost-Effective Open Ethernet

NVIDIA^® Spectrum^®-3 based SN4000 is an open ethernet switch that combines industry-leading cloud features with groundbreaking performance to support modern scale-out distributed data center applications. With support for all speeds 1GbE through 400GbE, SN4000 is ideal for building large layer-2, layer-3, and virtualized network fabrics for both green field and brown field environments.

Spectrum Networking Advantages

NVIDIA Mellanox What Just Happened (WJH)

Visibility

NVIDIA Spectrum SN4000 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.

Spectrum switches deliver a robust high bandwidth

Performance

NVIDIA Spectrum SN4000 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^®.

Scale

NVIDIA Spectrum SN4000 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.
