Open-source book about sourcing. Want to join?

International collaboration and publishing results using a Creative Commons license is hot. The next in line after the OpenDCME model, the Open Green IT Policy and the Greening IT Initiative is The Sourcing Initiative.


"Right Sourcing has a great potential to help organizations to optimize resource use, and to cut waste of human labor and energy, resources and capital. It has also the potential to create adaptive organizations that stimulate, enable and improve collaboration to mutual benefit for all who are involved.

Our mission is to write an creative commons licensed, internationally collaborative, non-profit book on how enterprise architecture can help in defining a sourcing strategy and improve sourcing decision making in order to create an agile organization."


OpenDCME used to assess Dutch universities

The IT and data center energy efficiency of nine Dutch universities was assessed during 2010. The project was initiated and sponsored by SURFfoundation and Agentschap NL and it was performend by Mansystems DCE. The facts are:

  • overall summary: too old, too empty, too cold
  • 179 GWh yearly energy consumption; similar to 50.000 households
  • 22% of this amount is IT where desktops take 13% and data centers 9%
  • 2,226 servers, 31,371 desktops, 13,044 laptops and 602 thin clients
  • rapid adoption and implementation of virtualization and storage thin provisioning
  • lot of IT trend monitoring; hardly any at data center equipment level
  • energy is not in the hardware TCO
  • average DCiE is 50%; targeted DCiE for this sector is 71%
  • 25,000 employees, 179,000 students
  • 44% energy reduction possible using measures like energy efficient hardware with power management and raising the data center temperature

The presentation and a summary of the results (both Dutch; use Google Translate or other to attempt translation) are found at and


We want your testimonial

Dear OpenDCME supporter,

Per today, the OpenDCME website supports recording and publishing testimonials of users of this data center efficiency model, and anyone else who has a constructive opinion about it. We would like to invite you to add your testimonial to it. On the page you find the instructions on how to proceed. When we have a representative set of testimonials of our direct community, we will enable this feature to the public.

Where are the energy and capacity efficient application developers?

Both Cap Gemini and Yahoo announce new data centers that have very low PUE's ( The numbers must be based on assumptions and I look forward to see the real production numbers over 2011 and 2012. The customers/users of such energy efficient data centers make a great decision to move there. If the data center in itself cannot have a low PUE, even with theoretic numbers, then you as its user will never be "green", "cost effective", "energy efficient" or whatever you like to call it.

Hosting your IT in a data center that is capable of scoring a low PUE is the first step. Then optimize the capacity utilization of your IT equipment to make effective use of the consumed energy (see for a blog about energy elasticity). And the next step? Optimize the applications and make them more efficient! Where are the energy efficient application developers?
