The Intel presentation was quite interesting in the respect that it highlighted the developments in energy efficient IT and how progress is being made in this area.

There was a mention of the power usage of a typical user, I’ve summarized this:

  • 1015w - standard configuration pc with CRT screen
  • 938w - if we swap the CRT for a TFT
  • 655w - if we switch to a newer more energy efficiency processors
  • 229w - if we use the newer more processors and enable power management

It illustrates how much of a difference can be made with small changes to system configuration, for example enabling power management, or even switching the pc off.

There was a great example showing two configurations:
2004

  • 126 servers
  • 6 racks
  • 48kw

2007

  • 17 blades
  • 1 rack
  • 6kw

As a result we have:

  • Reduced floor space by 83%
  • Reduced the energy cost by $53,000
  • Uses 87% less power

There was also a presentation from Easystreet which talked about PUE, a very interesting concept which I hadn’t heard about. It’s a way of establishing how efficient your data center is. In summary, it’s:

  • Total facility power/IT Equipment power=PUE
  • The objective should e 1.0, the typical data center is 2.0
