This session explores the infrastructure transformation required to build AI-ready data centers. Attendees will learn how AI drives fiber densities, demanding new approaches to network architecture, cabling, and connectivity. The presentation covers the latest GPU technologies, the role of advanced protocols like RDMA over Converged Ethernet (RoCE) and InfiniBand, and the shift toward high-density, scalable optical networks for scale up / out / in and across. Practical challenges such as cabling complexity, sustainability, and the need for structured solutions based on real-world examples.
