NVIDIA Spectrum 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 SN2000 Open Ethernet Switches
The Industry’s Fastest 25/100GbE Switch
NVIDIA® Spectrum® SN2000 provides the highest performance with 1/10/25/40/50/100GbE speeds. With comprehensive support for virtualization and large forwarding tables, Spectrum SN2000 is ideal for building large layer-2 and layer-3 data center fabrics. Additionally, SN2000 is optimized for storage workloads, with unique switch form factors that integrate into hyperconverged Infrastructure and software-defined storage management system for ease of deployment and administration.

SPECTRUM NETWORKING ADVANTAGES
NVIDIA Spectrum switches feature a fully shared and monolithic packet 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 switches support best-in-class Virtual Extensible LAN (VXLAN) with support for 6X more tunnels and tunnel end points. Its 256K 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.
