DEPLOYING LIQUID COOLING IN THE DATA CENTER – A GUIDE TO HIGH-DENSITY COOLING
The future of IT thermal management has arrived, and it’ s a hybrid of air and liquid cooling technologies. Enterprises are adopting high-performance computing( HPC) for artificial intelligence( AI) and machine learning( ML) model training and inference, causing a fast rise in chip, server, and rack densities, power consumption, and heat levels. Air cooling alone can’ t abate hot-running equipment effectively. As a result, many data center teams are strategizing how best to make their cooling strategy futureready in support of evolving business requirements. Nearly one in five data centers( 17 %) already use liquid cooling, whereas another 61 % of operations teams are considering it for their facilities.
While some new facilities will be specifically designed for AI workloads and liquid cooling, most deployments will occur in existing facilities. Multi-tenant data center( MTDC) owners and operators are driven to increase their competitiveness. They know that offering HPC capabilities for AI and other workloads will quickly become an industry standard. As a result, many are developing a business case to incrementally add liquid cooling across racks and rooms, evaluating different options, and creating a roadmap to phase in the adoption of new solutions.
IT, facility, and power teams will need to work together closely to deploy liquid cooling at existing facilities, as they will redesign buildings around rack, power, and cooling requirements. Readers of this technical guide are likely seeking insight into how to deploy liquid cooling to support rack densities up to, and in some cases exceeding 50 kilowatts( kW) per rack. �
