The purpose of this book is to discuss datacom (data center and telecommunication) power trends at the equipment level as well as to describe how to use those trends in making critical decisions on infrastructure (e.g., cooling system) requirements and the overall facility. There is an information gap that needs to be bridged between the information technology (IT) industry and the facility design\/construction\/operation industry. Today\u2019s datacom facilities require a holistic approach, balancing the tradeoffs between datacom equipment and facility cooling infrastructure. Based on the latest information from all the leading datacom equipment manufacturers, Datacom Power Trends and Cooling Applications provides new and expanded datacom equipment power trend charts to allow the datacom facility designer to more accurately predict the datacom equipment loads that the facility can expect to have to accommodate in the future as well as providing ways of applying the trend information to datacom facility designs today. Also included in this book is an overview of various air and liquid cooling system options that may be considered to handle the future loads and an invaluable appendix containing a collection of terms and definitions used by the datacom equipment manufacturers, the facilities operation industry, and the cooling design and construction industry.<\/span><\/span><\/p>\n
