In this special guest feature, Bob Fletcher from Verne Global reflects on how liquid cooling technologies on display at SC19 represent more than just a wave. “My intuition suggests that the larger established water-cooling users will mostly stick with their familiar high-pressure solution, but the newer green field deployments will be fertile ground for the new vacuum CDUs. In particular, the AI community as their compute accelerators become increasingly water-cooled, while maintaining their short 2-year product life.”
