Your Guide to the Latest Windows Server Product Information
I've posted about power management and Windows Server before so you may recall that one of our goals for Windows Server 2008 R2 was to enhance power management. You might also remember that R2 can help improve power efficiency by up to 18% over Windows Server 2003 running on the same hardware. Now there's another data point available on the potential of R2 to help save power.
The US Environmental Protection Agency (EPA) published a paper last week on Enterprise Servers which discusses the results of some recent power efficiency tests comparing an HP server from a few years ago running Windows Server 2003 with a modern Energy Star-Qualified HP server running Windows Server 2008 R2. A few highlights from the website and paper:
Several major OEMs, including HP who contributed to the testing as discussed in the paper, have now released servers which have obtained the Enhanced Power Management Additional Qualifier during their Certified for Windows Server 2008 R2 logo certification (http://www.windowsservercatalog.com/). These servers work with Windows Server to improve power efficiency "out of the box" without requiring manual configuration, provide additional power monitoring capabilities, and even enable power budgeting.
R2 offers the possibility to impact the environment - and costs - in a worthwhile way, whether your organization is large or small. And now you can read more about the potential for power savings from the EPA.
