Making Energy Efficient Servers Easier to Find
The new Energy Star rating for enterprise servers - which was originally supposed to be launched on January 1st, 2009 - is coming on May 1st. Historically, computer servers have been optimized mostly for performance, but in the past few years, power consumption and heat dissipation have become extremely important and this new tool should help those who buy servers make better informed choices. Read on for more details.From DataCenterKnowledge:
The Energy Star for Enterprise Servers spec will cover servers with one to four processors, and set efficiency goals for servers at full load and also when idle. The standard will emphasize efficient power supplies and power management tools. To achieve an Energy Star rating, a server must be able to measure and report power usage, temperature and processor utilization - and those features must be turned on when a server ships.
It might surprise some (and not others) to learn that many of the power-saving features that are currently available in most servers are under-used or simply not used at all.
The latest draft, version 4, is available on the Energy Star website. "Comments on the latest draft are due March 20, after which there will be a stakeholders meeting and conference call, with the final spec scheduled to follow on May 1."
A bit of trivia: The well-known energy star label won't be placed directly on servers. Instead it will be shown on the vendor websites, linking to more info.. The reason? "Some commenters, including The Green Grid, argued that placing a label on the server could impact thermal performance or mechanical fit of servers in racks."
We'll have to wait for the final version to know the specifics, but if you want to check out the draft requirements to qualify for the energy star logo, see page 10-18 (tier 1) of Draft 4 (it varies depending on the number of processors, etc).
