Data Center Energy Efficiency Rebates

Posted on May 12, 2009 by James Cerwinski

Data Center energy efficiency rebates are a win-win.

An abundant supply of inexpensive energy is fuel for the world economy.   Four of the last six recessions were caused in part by high energy prices and supply concerns.  $454 billion was spent by energy exploration and production companies in 2008 according to a survey of 357 oil and gas companies by Barclays Capital.  In comparison, the U.S. Department of Energy spend only about $650 million on energy conservation. It will take both new supply and energy conservation to meet our energy requirements.

I applaud Pacific Gas and Electric and San Diego Gas and Electric for making an investment in energy conservation.

Pacific Gas and Electric is the leader in offering Data Center energy efficiency rebates and incentive programs.  Over the last three years they have announced rebate programs to replace existing servers with new energy efficient servers and rebates to consolidate servers through virtualization.  It is important to contact them for rebate approval before you implement your plan.  They pay $158 per consolidated server.

San Diego Gas & Electric Company offers financial incentives for server virtualization projects. SDG&E offers an incentive of 8 cents per kilowatt hour saved. If you’re running an green data center, this should be a big help.

Carbon Cap and Trade Data Centers

Posted on April 21, 2009 by James Cerwinski

By now you have heard of carbon cap and trade programs, but most likely this was in reference to activity in Japan or Europe.  This blog is notice to you that it will be coming to the United States soon and you should understand what it means to you.

The attached document provides and overview of greenhouse effect and carbon cap, what it will mean to you and how some Japanese companies took advantage of this opportunity.

Data Center Efficiency (PUE) Best Practices

Posted on April 14, 2009 by James Cerwinski

Google hosted a summit on Data Center Efficiency Best Practices with industry leaders on April 1, 2009.   It was a day long event. You can watch videos with good information on how to make your data center more efficient.  Data Center Efficiency Best Practices Summit

James Hamilton, VP and Distinguished Engineer Amazon Web Services, presented a strong case for his best practices.  He explained that you can achieve a 2 times gain over current averages without advanced techniques. He proclaimed - “metrics drive behavior”.  I fully agree with him on that point.  He challenged data center managers to push the limits and to rely more upon control software. One of his many best practices is “Power Yield Management”.  He explained that power is the most valuable resource.  Therefore it should be over sold just as an airline sells more seats than the airplane holds to ensure a higher utilization.

He also gave reasoning on why we should run data centers at a higher temperature. This one chart gives ASHRAEs’ recommendation, range most data centers operate and the Dell PowerEdge 2950 warranty level - a shocking 95 degrees. Temperature Chart

What is the temperature of your data center?

Change Management

Posted on January 3, 2009 by Minder Singh

Managing change in the data center can be painful. But relief is at hand.

Manage moves, adds and changes in your data center easily and efficiently with Raritan’s DCIM solution.

It’s no secret that data center operations are more complex than ever. There’s a constant stream of devices being added, removed, repurposed and reassigned at any given moment. This means data center operators are always dealing with questions like:

  • How do I manage a multitude of moves, adds and changes?
  • Who does the work?
  • How will I know when the work is done?
  • More importantly, how will I know if it’s done correctly?

Capacity Management

Posted on January 3, 2009 by Minder Singh

Running out of power, space and cooling?
Now it’s easy to manage the resources you have left.

With Raritan’s DCIM solution, information is at your fingertips to easily see capacity in your data center.

The demand for resources is on the rise in data centers and IT labs around the world. But most IT facilities only have a finite amount of space, power, cooling and connections capacity to work with, so it’s critical to know:

  • How much you have
  • Where you can deploy new IT equipment
  • How you can better utilize it
  • When it will run out
