Explore a detailed "show and tell" presentation from HPE's ProLiant liquid cooling team focusing on innovative cooling technologies for modern data centers. Keith Sauer, Mechanical Engineering Manager, introduces the Houston-based engineering team's critical role in designing mechanical and thermal elements for ProLiant servers, explaining how air cooling has evolved from an afterthought to a significant design consideration. As power densities increase in modern hardware, Pranay Mahendra, Mechanical and Thermal Engineer, demonstrates how traditional air cooling has reached its limits, necessitating the shift toward liquid cooling solutions. Learn about HPE's closed-loop liquid cooling (CLLC) systems that incorporate internal radiators, pumps, and cold plates within compact server formats, capable of handling up to 450 watts of thermal load. Discover how direct liquid cooling (DLC) solutions integrate with facility-level liquid infrastructure to deliver even greater cooling performance, enabling sustained processor turbo modes and higher efficiency. The presentation addresses practical concerns like leak detection, serviceability, and lifecycle considerations while providing economic comparisons between different cooling approaches. Gain insights into how to evaluate cooling solutions based on power requirements, rack density, performance needs, and sustainability goals, with the understanding that air cooling remains viable for many data center configurations. This 36-minute technical session was recorded live at the HPE Customer Innovation Center in Houston on April 8, 2025.
