Processor Power Management in Windows Vista and Windows Server 2008

Windows Vista® and Windows Server® 2008 include updated support for ACPI processor power management (PPM) features, including support for processor performance states and processor idle sleep states on multiprocessor systems. This paper provides details of the support in Windows Vista, describes how PPM works with Windows Vista power policy, provides guidelines for firmware developers and system designers, and includes details on how Windows Vista may be tuned to optimize the balance between performance and power savings.

Power In, Dollars Out: How to Stem the Flow in the Data Center

Server Power Considerations for IT Administrators

This document provides a comprehensive analysis of the server power landscape for information technology (IT) administrators. It explains the effect of server power usage on total cost of ownership (TCO) for IT organizations, shows the intricacies of the power-versus-performance tradeoff in the server realm, and describes in detail how the many Windows Server® system configuration parameters that IT administrators choose can affect power efficiency.

This information applies for the Windows Server 2008 operating system.

Recommendations for Power Budgeting with Windows Server

Inefficient allocation of power and cooling resources in data centers can result in unused power capacity. This increases costs and artificially limits the number of servers that can be deployed. To address the overallocation of power budgets, many server vendors have introduced power management solutions that try to enable the capping of power consumption on a per-machine basis to reduce the unused capacity. However, some of these solutions can have negative or unintended consequences when they overlap, conflict, or otherwise interfere with the power management capabilities that are supported in Windows Server operating systems.

This paper summarizes common approaches to power budgeting in the server marketplace and recommends best practices to ensure that these solutions work as intended and interoperate with Windows Server power management capabilities. The information in this paper is intended for product planners, developers, and system designers.
