SYNOPSIS

The exponential growth of Artificial Intelligence (AI) workloads is fundamentally reshaping the landscape of data center design, with thermal management emerging as a paramount concern. Traditional air-cooling methods, while prevalent, are increasingly struggling to cope with the ultra-high power densities and localized heat generated by modern AI processors (GPUs). This talk will explore the critical need for hybrid cooling systems in next-generation AI data centers, particularly within the context of a tropical climate like Kuala Lumpur, Malaysia.

The discussion will outlining the unique thermal challenges posed by AI, including liquid and air cooling thermal strategies for high density server in the extreme weather, fundamental principles of liquid cooling, energy measurement by specialized energy valves and energy efficiency, metrics like PUE and WUE. The limitations of solely air-cooled or solely liquid-cooled approaches will be highlighted, making a compelling case for the synergistic benefits of hybrid solutions.
