Energy Star for servers coming in February, EPA says

The U.S. Environmental Protection Agency is one step closer to setting power efficiency ratings for servers.

The U.S. Environmental Protection Agency has released the third draft of its Energy Star specification for servers and expects the final spec to be ready for use in February.

The specification aims to help customers identify the most power-efficient servers when making purchases. The Energy Star program already covers desktop PCs, monitors, light bulbs and dozens of other products. Products are identified with an Energy Star label.

The third draft establishes power consumption limits for when a server is in an idle state, something that had not been established in the second draft. To qualify for the Energy Star logo, vendors must also meet minimum requirements for power supply efficiency and publish a data sheet for each server indicating its power and performance levels for maximum, minimum and typical configurations.

The specification covers servers with up to four processor sockets. The EPA said it chose to exclude blade systems from the draft because SPEC indicated that its SPECPower_ssj2008 benchmark for measuring idle consumption can't run on blades. Future specifications will "look for appropriate ways to address blade systems," the EPA said.

The specification is due to take effect on Feb. 1, 2009. A more comprehensive "Tier 2" specification planned for October 2010 may include servers with more than four sockets.

The idle power limits have been set at 60 watts for one-socket systems and 271 watts for four-socket systems. Additional components are given an additional power allowance. For example, a second hard drive gets an additional 15 watts of power.

The third draft is due to be posted soon to the EPA's Energy Star for servers Web site.

It really doesn’t get more “gaming laptop” than this.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
