Windows Server 2008 Power Savings
Energy-efficient computing is a priority for businesses and organizations seeking to control costs and reduce environmental impact. The Windows Server 2008 Power Savings white paper highlights features such as virtualization that reduce the power consumption of server and client operating systems, minimize environmental byproducts, and increase server efficiency.
The whitepaper summarizes out-of-the-box power savings through updated support for Advanced Configuration and Power Interface (ACPI) processor power management features that include processor performance states and idle sleep states on multiprocessor systems. More significant power savings are made possible by Hyper-V, the hypervisor-based virtualization technology included as a server role in Windows Server 2008. Hyper-V makes it possible to consolidate servers onto a much smaller number of physical machines. Fewer physical machines can lead to reduced costs through lower hardware, energy, and management overhead, plus the creation of a more dynamic IT infrastructure.
