The increasing demand for artificial intelligence (AI) and machine learning (ML) applications is fueling investments in data centers around the world. As AI and ML drive the need for high-performance chips, data center managers are faced with the challenge of designing infrastructure that can support high heat loads while still being able to scale operations to meet demand. This scalability cannot always depend on more physical space, requiring data center managers and engineers to solve the technical problem of fitting more and hotter servers into the same spaces.
A key consideration for data center managers is maintaining 24/7 uptime, as the needs of AI applications will not pause for a data center renovation. Additionally, the industry is facing increased scrutiny over power use, leading data center managers to be especially conscious about how they are using electricity. Sustainability has always been a conversation in the data center industry, but the increased attention will create even more dialogue around Power Usage Effectiveness (PUE) and power management.
In response to these challenges, data centers are turning to liquid cooling technologies. Liquid cooling provides a much greater heat transfer capacity than air, allowing data center managers to increase capacity while maintaining efficient space and energy use. By utilizing liquid cooling, data centers can improve PUE, lower energy costs, and contribute to environmental sustainability.
The heart of a liquid cooling system lies in selecting the right coolant distribution unit (CDU). CDUs pump cooled fluid to racks and chips in a closed loop, with precision control adjusting fluid temperature and flow rates to maximize efficiency. Reliable liquid systems are essential to minimize the risk of leaks, as any joint in the facility water system or technology cooling system loops represents a potential failure point if not properly vetted.
When selecting a CDU, data center managers must not only consider the maximum thermal and hydraulic performance possible but also examine the suitability of critical CDU parts for the specific application. Critical CDU parts must go through a higher rigor of selection and design verification to ensure reliability and minimize the risk of leaks. CDUs designed for manufacturability will prove most beneficial in meeting the short and long term quantity needs of the industry as demand for data centers continues to grow.
Serviceability of field-replaceable components and the true cost of ownership are also crucial factors to consider when designing a CDU. Improved serviceability, along with selecting components that have obvious failure modes, will reduce the cost of ownership during the unit’s course of operation.
As the demand for AI and ML applications continues to rise, data center managers are turning to liquid cooling technologies to meet the challenges of high heat loads and increased power use. By selecting the right CDU and considering factors such as reliability, leak integrity, and serviceability, data center managers can ensure their infrastructure is equipped to handle the demands of next-generation chips while maintaining efficiency and sustainability.
