As I've blogged about previously, the Energy Star spec for servers isn't even close to being ready for prime time, even though it is expected to be released May 1. The spec won't cover blade servers, even though blade servers are the servers of choice for anyone interested in greening their data center, are the most energy-efficient of servers, and are the key for virtualization projects. Leaving out blade servers means that the spec will help very few data centers.
In addition, the spec only gauges the power a server uses when it's idle. But servers are rarely, if ever, idle. They're designed to be constantly running. So that part of the spec is of no use at all.
There are even more problems with the planned Energy Star spec for entire data centers. In fact, the problems are so severe, the spec may never come into being. In order to develop the spec, the EPA needs real-world data from data centers about power consumption. But Data Center Knowledge reports that data centers simply aren't cooperating. It notes:
More than half of the data centers that agreed to submit energy usage data to the Environmental Protection Agency have not shared any data, according to Andrew Fanara, the agency's liaison to the data center industry. The EPA's National Data Center Energy Efficiency Program wants to use the data to develop a model for a facility-level efficiency standard. Data center operators' reluctance to share data with the government imperils that effort.Fanara was blunt about twhat that means. He told the DataCenterDynamics event in New York that "Unless people participate, we can't deliver this."
This is just a continuation of problems with the spec, notes Data Center Knowledge:
The program was initially scheduled to start last June 1, but was delayed when just 50 data centers agreed to take part. After additional appeals for participation, 242 data centers agreed to submit data and the program launched a month late. Companies agreeing to submit data included Microsoft, AT&T, AOL, 365 Main, Rackspace, Fidelity Investments, Lowe’s, New York Life and Boeing.My guess: This spec may never happen. And even if it does, judging by the poor job done with the server spec, it may not be of much use to anyone.
But eight months into the program, just 110 data centers have shared their energy data, and only about 85 of those have submitted complete data.

ENERGY STAR for Servers
Preston,
We at Emerson Network Power applaud the EPA for their efforts to launch an ENERGY STAR™ for servers specification. The ENERGY STAR for servers specification is being developed in a committee process and not a government mandate issued forth by a team of one. This means it has been subject to the market forces of the very server manufactures it attempts to regulate who have pushed back from day one at any extension beyond the mundane power supply.
Now we finally have a meaningful attempt to monitor and report “idle” performance. Since recent data shows that servers, of all configurations and especially 1U and 2U volume servers which represent over 80% of typical idle energy draw during the day, are idle for 90 to 95% of the time this represents a huge step forward towards true energy savings.
Now if you would really like to help the cause Preston issue a call for IT professionals to start turning their idle machines OFF. Then we could finally see some serious productivity improvements in this country. We address the productivity issue (useful work) with CUPS, Compute Units Per Second. http://www.emerson.com/edc/docs/EnergyLogicMetricPaper.pdf
Thank you for drawing the attention to the ENERGY STAR for servers specification. There still is time for your readers to act and comment on the specification.
Best regards.

Blade servers to be included in ES server spec
As I mentioned in a comment to your blog from 2/3/09:
In a letter dated February 20, 2009, the EPA invited input on draft 4 of their server specification and they specifically announced the inclusion of blade servers in the spec. Here's the web address to that letter.
