Data centers are essential for the digital economy. They have returned to popularity as an alternative to cloud-based services for organizations that prefer to keep their data on-premises. Additionally, organizations are learning that having their infrastructure only in the public cloud might not be the most cost-effective solution. This renewed focus on data centers brings new challenges: reducing energy consumption while still satisfying demands for more powerful compute and infrastructure, selecting the right cooling systems for now and the future, and rising operational costs that can directly impact a data center operation’s bottom line. This study explores the latest trends and best practices in data center power and cooling efficiency, emphasizing the need to balance performance and costs.
