About this episode
This episode explores the future of data center networking with a focus on 100 terabit smart switches and the impact of AI infrastructure.
Thank you to Cisco for sponsoring my trip to the Cisco AI Lab in San Jose. In this deep dive into the future of data center networking, we sit down to explore the massive shifts happening in AI infrastructure. We discuss the rollout of new 100 terabit smart switches and firewalls powered by the Cisco Silicon One G300 chip, alongside the highly anticipated NVIDIA Spectrum 6. Discover the critical debate between Ethernet and InfiniBand for scaling AI clusters, the complexities of co-packaged optics (CPO) versus linear packaged optics (LPO), and how agentic AI and tools like Claude are revolutionizing legacy C code refactoring. From managing data center power constraints to enforcing security policies directly on DPUs, this conversation covers the hardware and software transformations you need to know to stay ahead in network engineering. // Will Eatherton SOCIAL // LinkedIn: / willeatherton Newsroom: https://newsroom.cisco.com/c/r/newsro... // YouTube video REFERENCE // • The 100Tbps AI Switch: Inside the Beast • Did Ethernet Just Win?
