PUE vs DCIE. Metrics for data center energy efficiency

I thought how to present two very important metrics for all data centers – PUE (Power Usage Effectiveness) and DCIE (Data Center Infrastructure Efficiency). Thanks to the white paper from The Green Grid, titled "Green Grid Data Center Power Efficiency Metrics: PUE and DCIE" – I found a perfect solution. We need both metrics to take care about greater energy efficiency and there is no doubt at all – data center is a significant cost for any organization, especially when it comes to the energy consumption. It's even more irritating, when we realize that – in comparison to the IT – mostly cooling systems are the cost generators in data center. Hence, there are natural questions – how can we be more efficient? How can we use our resources more effectively? How to reduce data center TCO (Total Cost of Ownership)? What can we optimize? Well… We can do a lot of improvements, but without proper metrics we cannot even start to think about them. So, let's read about PUE and DCIE.

100th Birthday of Alan Turing – let’s learn from the past

Alan Turing (23 June 1912 – 7 June 1954), was an English mathematician, logician, cryptanalyst and computer scientist. He is also considered to be one of the Fathers of computer science and artificial intelligence. Today, (23 June 2012), he would be 100 years old! It's time to celebrate with deeper reflection. I believe that if he wasn't hunt down with intrigues and close-minded society prejudices, he would make our world a much better place to live today. And today, in the times of – so called – "crisis" we should re-consider the behavioral patterns and learn from the best examples from the past. Alan Turing is definitely a good example – not only he was a multi-talented genius, he was also the dreamer, the visionary and a very productive and committed person. I would like to recommend a very comprehensive and incredibly-well written article: "The highly productive habits of Alan Turing" by Matthew Lasar and published in ArsTechnica.com.

openDCIM 1.1 available

Better late than never – there is a new version of openDCIM available. The number was changed from 1.0 to 1.1, so we shouldn't expect revolutionary changes, but still… The project is on-going and several things were improved.

DCPM vs DCIM. Any difference?

DCIM is still a hot subject in the data center world. Nothing strange, as these systems help to fill the gaps between facilities and IT, integrate multiple data sources, ease planning and reporting, hence increase management capabilities. There are many offers available from a well-known market leaders as well as smaller companies. Previously, we covered Raritan dcTrack, nLyte, we mentioned DCIM importance on many other occasions (see here for full list of articles), we even presented open source alternative – which is work in progress, but looks very promising – openDCIM.org. Now, DCPM comes to play. What's that?
