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 website and paper:
- In some of these tests, new ENERGY STAR server consumed 54% less power than the older model servers and OS.
- The power savings also come with a substantial increase in performance - at 50% utilization, for e.g., the newer, more energy-efficient server and OS handle over three times the work, thereby helping reduce the number of systems needed to support a given workload.
- The total savings over the useful lifetime of a server is estimated at between $480 and $1,440 per server.
