Semiconductor Engineering examines the data center race toward racks consuming up to one megawatt, and the changes this requires in cooling, power distribution, and three-dimensional design. The article presents an alternative path based on distributed computing, specialized chips, and optical interconnects to avoid concentrating this load in a single rack.
Semiconductor Engineering explains that the traditional reliance on copper inside a server or rack is no longer a fixed rule as AI clusters grow, as loss, distance, and power constraints drive the introduction of optical links into the scale-up range. Optical circuit-switching networks are also gaining increasing attention, alongside the evolution of infrastructure-scaling terminology and methods.
