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.
Nvidia Spectrum SN4000 Open Ethernet Switches

Visibility
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.
