Cisco Nexus 9000 Architecture - BRKDCN-3939#

Cisco Live US 2025 (San Diego) digest Program Core pick San Diego · 8–12 June 2025

Abstract

Faraz Taifehesmatian (Cisco)

  • Why: Switching silicon and forwarding internals are squarely in the PM's core interest; this is the deep-dive on the ASIC generation that underpins the AI-fabric sessions above.
  • What: An in-depth architecture study of the latest Nexus 9000 modular and top-of-rack switches: ASIC architecture, forwarding mechanics, physical design elements, and the hardware-enabled features that deliver DC network services (from abstract only).
  • How: Architecture walkthrough from silicon to system.
  • Where applicable: Cisco-specific silicon, but the trade-offs discussed (buffering, forwarding pipeline, physical design) are transferable to evaluating any modern DC switch ASIC.
