Server Power Considerations for IT Administrators
This paper presents a comprehensive analysis of the server power landscape for information technology (IT) administrators. It explains how power affects the IT budget, shows power and performance tradeoffs, and describes in detail how hardware and software can affect overall power efficiency in the data center. Administrators can use this information to make power-aware deployment and purchasing decisions, identify issues and inefficiencies on deployed systems, and maximize their organization's power efficiency.
This information applies for the Windows Server 2008 operating system.
