Hardware Architecture & Core Design Principles
The N9K-C93180YC-FX3= is Cisco’s flagship 1/10/25/40/100G Ethernet switch for hyperscale data centers, built on three foundational pillars:
- Cloud-Scale ASIC Technology – Cisco’s Cloud Scale P100 ASIC delivers 12.8 Tbps non-blocking throughput with 3.2B packets/sec forwarding
- High-Density Port Configuration – 80x 100G QSFP28 ports + 48x 10/25G SFP28 ports in 2RU form factor
- Modular Airflow Design – Front-to-back or port-side exhaust configurations (NEBS Level 3 compliant)
