The State of Data Center Cooling: A Review of Current Air and Liquid Cooling Solutions

This paper provides basic guidance for selecting the right cooling methodology for multiple types of data center projects, as well as varying densities of new servers. It focuses on proven cooling technologies can use right now, rather than emerging technologies. Data center provisioning is a multidimensional problem with a variety of constraints. Those constraints drive the choices, and choices need to be compared based upon a thorough analysis of each option's Total Cost of Ownership (TCO).
