The US Environmental Protection Agency (EPA) published a paper last week on Enterprise Servers with results of recent tests comparing the servers of a few years ago with more modern Energy Star-Qualified server equipment from Hewlett Packard using Windows Server 2008 R2. One of the key findings suggests that replacing an older server with a new ENERGY STAR-qualified model and modern operating system will save energy and deliver more processing power.
Windows Server 2008 R2 shipped with enhanced power management that saw improved power efficiency by up to 18% over Windows Server 2003 running on the same hardware. Combined with Windows Server 2008 R2, the new ENERGY STAR servers consumed 54% less power than older model servers. What about cost savings? The total savings over the useful lifetime of a server is estimated at between $480 and $1,440 per server. That’s significant savings especially for companies using hundreds or even thousands of servers.
These results show the industry is making progress on power management. Several Microsoft experts including the environmental sustainability team’s Mark Aggar and the Windows Server team’s Dan Reger contributed to the paper.
