Energy Efficient Servers: Blueprints for Data Center Optimizationintroduces and describes for IT professionals the latest server power management technologies and how they work. It explains how these technologies are utilized and what role software plays in their operation, explaining the power and performance trade-offs of each technology, and how these trade-offs differ across various environments. The book teaches the reader how to optimize their environment to use power management technologies to best fit their needs. It shares optimization techniques used by data center administrators and system optimization experts at the worlds most advanced data centers.

The book illustrates these fundamental concepts with examples from common cloud, enterprise, and HPC environments and it empowers the reader to study and understand their own environment though detailed explanation of monitoring and characterization techniques. Building upon this combination of theory, real world examples, and practice, the book helps the reader develop deep understanding and expertise, dispeling common misconceptions about server configuration, component selection, and performance impact of power management.
