Leaving home 4 hours in advance with a TomTom driving time of 1.5 hours still gave me some shivers. I arrived 15 minutes in advance of my presentation on PUE in Brussels thanks to the never disappearing traffic congestions. The radio announced over 200 km traffic jam in Belgium. One hour driving time Turnhout- Antwerp, instead of the regular half an hour and the same for Antwerp-Brussels. The information of the length (time) of the total congestion has some similarities with PUE in the data centre: both are quit recently introduced and both are good KPI’s (key performance indicators) which give an indication of the status of the system. For informing the local traveller the indication of driving times works better than length of the local traffic jam. Similar with PUE. The overall PUE gives information the effectiveness of the whole data centre, but without information on the individual power consumers the information is not useful.
Being first speaker gives the advantage of having a relaxed seminar with a lot of information on different data centre subjects.
The different speakers on data infrastructure aspects in the DC showed a strong tendency of moving all the cabling to the top of the data centre. Cabling above the racks gives clear vision on what is happening and avoids air path obstruction which might occur with under floor systems. Fibre optic cabling is winning ground with the ever increasing speeds in the data centre. With either active or passive top of the rack infrastructures. Storage and network cabling topologies are fading into each other with an ever stronger presence of Ethernet in the DC. Intelligent transporting of network traffic between end-user and data centre results in less costs, lower latencies and increasing customer satisfaction. Spreading the tendency of larger data centres, more virtualization and more use of cloud services.
Back to my own presentation on PUE, here you will find some background information on my Lannews presentation on February 16, 2012 in Brussels. If you would like to receive the complete presentation please send an e-mail to: email@example.com.
The Green Grid information can be found in white paper 22 : USAGE AND PUBLIC REPORTING GUIDELINES FOR THE GREEN GRID’S INFRASTRUCTURE METRICS (PUE/DCIE).
In the Netherlands the Dutch Green Building Council starts with a BREEAM certification program for data centres, and you can find the next slogan on their site: WORDT UW PROJECT HET EERSTE BREEAM-NL GECERTIFICEERDE DATACENTER?
BREEAM is also active in Belgium but not yet for data centres as I know off.

The EU, US and Japan started an initiative to create a common standard for PUE. Resulting in the document : Recommendations for Measuring and Reporting, Overall Data Center Efficiency, Version 2 – Measuring PUE for Data Centers
A lot of information on PUE you will find in Our White paper :Tips and Tricks for the professional use of PUE as a management tool.
