Cisco Scales AI Networking with New Silicon and Systems

"At AI-factory scale, performance is no longer determined by the network or the data layer alone - it’s defined by how tightly they work together. Cisco’s Silicon One G300–powered Nexus platforms provide the deterministic, high-bandwidth fabric required for agentic and GPU-dense environments"

Sven Oehme, CTO

DDN

Building the future of global connectivity

"We talk with Cisco on a daily basis about how we can make the network better and make deliveries as smooth as possible. The network is not up 100% of the time, so transparency and a deep understanding of how the network is performing—that’s the key to customer experience."

Mattias B. Fridström, Vice President and Chief Evangelist
