Two thirds of professionals are unaware of PUE

Date: 19th November 2010

Two thirds of professionals with data centre responsibilities are unaware of PUE ratings.

Less than a third of senior management professionals and data centre decision makers are aware of the Power Usage Effectiveness (PUE) rating of their IT facilities according to Keysource. This worrying statistic from research undertaken by the data centre solutions provider amongst attendees of its regional seminars this year highlights the need for greater understanding of IT energy consumption.

However, the research does suggest some encouraging developments during the past 12 months, with a noticeable increase of more than 20 per cent in the number of those now aware of PUE figures. In 2009, less than one in four data centre professionals knew of the PUE of their company’s data centres, so some positive steps have been taken this year.

Other findings point towards an ongoing improvement in PUE that is being achieved by UK data centres. Based on figures collected from those attendees aware of their ratings, the average PUE was 1.89. This compares to an average of 1.93 PUE in 2009, representing a year-on-year improvement of 2.1 per cent.

Commenting on the findings, Mike West, Managing Director of Keysource said: “Bearing in mind that PUE is recognised as the preferred industry metric for data centre energy usage, it is somewhat surprising that there is such low understanding of the measurement. With increasing pressure to improve the performance of data centres in terms of corporate responsibility, cost reduction and compliance, I anticipate far higher levels of awareness in the next few years.”

Keysource’s Data Centre Efficiency Audit not only measures the PUE of a facility, but also provides a better understanding of energy performance and identifies areas of improvement. This process can highlight quick wins and best practice to achieve savings of as much as 25 per cent with virtually no capital expenditure.

2011 Events

Keysource has been providing a free seminar programme for the past five years to keep data centre operators updated and informed on current and future issues. To ensure the 2011 programme meets the needs of attendees, the company is seeking feedback and opinion to help shape upcoming events. As a result, a short survey is currently running on our website here: http://www.keysource.co.uk/survey.
