– Yih Leong Sun,
Head of Infra, GMI Cloud
The real challenge in AI infrastructure isn't just performance—it's maintaining operational sanity as you scale from dozens to thousands of GPUs. Cisco's approach with NX-OS and Nexus Dashboard creates a single pane of glass across our entire AI fabric, whether we're optimizing inference latency in the front-end or maximizing training throughput in the back-end. That operational simplicity translates directly to faster deployments and lower TCO.
– Xiaohe Hu,
CEO, Infrawaves
AI has evolved from natural language-focused Large Language Models (LLMs) to agentic AI, and now to physical AI that operates in the real world. As AI becomes essential to enterprises, neoclouds, and hyperscalers, organizations need high-performance networking to support its explosive traffic demands.
Cisco is fueling the AI revolution with a unified data center network powered by Cisco N9000 Series switches and Nexus Dashboard.
