Data center power management, DataCenter
I didn’t know this, but I guess yesterday was “Power IT Down Day.” Hewlett-Packard, Citrix and Intel joined forces to propose the idea of asking PC users to install power management software that can decrease the power use of their machines when not in use.
I found out about “Power IT Down Day” this morning from Ken Oestreich, the director of product marketing at Cassatt Corp., who wrote a blog post about “Power IT Down Day” in his Fountainhead blog yesterday. Oestreich wrote that, although it’s a good idea, Power IT Down Day is also “missing the boat” because its sponsors stress PC power management, but not server power management. He goes on:
At the time of this writing, the official website at HP showed over 2,700 participants, saving an estimated 35,000 KWh. But here’s a sobering statistic: At a recent Silicon Valley Leadership Group Energy Summit, Cassatt piloted Server power management software. The organization using the software operated a number of its own data centers — and the case study findings showed that if this software were used enterprise-wide, the annual savings could be 9,100KWh for this enterprise alone.
You’ll never guess what Cassatt does. That’s right! It makes server power management software.
But the fact remains that Oestreich has a point. In a report to Congress last year, the federal Environmental Protection Agency recommended server power management as one way to reduce data center energy levels. Other industry groups like The Green Grid and The Uptime Institute recommend the same.
The good news is that data centers are listening. In our own purchasing intentions survey last year, only 18% said they were using power-down features on their servers, with another 13% saying they planned to sometime last year. Those numbers have since jumped. According to our new survey results from this year, 31% have implemented power-down features, and another 22% said they plan to sometime this year.
So I guess data center managers have gotten the hint. Maybe “Power IT Down Day” doesn’t have to be extended after all…
