From Air to Liquid Cooling: Importance of Containment

This white paper discusses the critical role of containment in the transition from traditional air cooling to liquid cooling in data centers. As data centers face increasing demands from AI workloads and next-generation servers, traditional air cooling is becoming inadequate. The paper outlines how containment serves as a necessary step in optimizing cooling efficiency by physically separating hot and cold air streams, which enhances energy efficiency and equipment reliability. It details the limitations of current air cooling methods, particularly in high-density environments, and presents containment as a bridge solution that allows data centers to scale up without immediate large-scale infrastructure changes. The document also explains the various containment strategies, such as hot aisle containment and cold aisle containment, and discusses their implementation based on specific operational requirements. By prioritizing containment, data center operators can effectively manage rising thermal loads and prepare for future cooling technologies.
