Overview
The SN4000 platforms are based on Spectrum-3 switch silicon and support up to a whopping 25.6Tbps of bidirectional switching capacity. Built for the modern data center, the SN4000 supports:
- Advanced granular telemetry with What Just Happend®
- Rich data center features at unprecedented scale with FlexFlow™ packet processing
- Consistent performance and ultra low latency
- Fair bandwidth sharing with fully shared packet buffers
Visibility without Compromise
Reduced Mean Time to Recovery/Innocence. Detailed and contextual
telemetry with What Just Happened (WJH). Instant answers to When, What,
Who, Where and Why questions as soon as an issue as it happens.
Hardware accelerated histograms track and summarize queue depths at a sub-
microsecond granularity. Avoids false-alerts common to simple watermarks/thresholds
Performance without Compromise
Fully Shared Packet buffer provides fair, predictable and high-performance
data path that is essential for scale out software defined storage and modern
multi-tenant cloud deployments
Robust RoCE transport to power NVMe over fabric and Machine
Learning applications that leverage GPUdirect
Scale without Compromise
Best in class VXLAN scale with support for 10X more tunnels
and tunnel end points
512K shared forwarding entries that can be flexibly shared across ACL,
LPM routes, Host routes, MAC, ECMP and Tunnel applications
