UK data centres need to embrace energy saving green technologies

UK data centres are starting to make efforts to become more energy efficient, but there is plenty of room for improvement, according to a recent survey by the organisers of Data Centre World 2012

On the upside, 71% have replaced inefficient equipment and 67% deploy measures to optimise cooling and airflow. A further 61% have adopted server virtualisation, which is a key strategy for both energy and cost reduction.

But 62% do not currently deploy low energy servers, 72% of management admit to failing to consult on energy requirements before making purchases and only 15% currently recycle heat from the data centre.

Overall, the results mean that the majority of UK data centres (76%) expect their energy consumption to increase or stay the same over the coming year.

Data Centre World conference director John Hatcher says it is encouraging that many data centres are moving towards greener technologies like server virtualisation.

“[But] the lack of communication within facilities teams is a concern and with budgets tight due to the stalling economy, it is surprising that server virtualisation rates are not higher,
” he warns.

The research also raises concerns that the lack of “informed decision-making” could cost the sector when it comes to the UK’s new CRC legislation, which requires large energy users to report carbon emissions and take action on making reductions.

In fact, just over half of those surveyed did not know their PUE – which provides a comparison of data centre energy performance – or have a below-average rating of above 2.0.

Although the UK has some of the most advanced data centres in the world, the survey shows there is still a great deal of work that needs to be done,” says Hatcher. “If we’re to see a credible reduction in data centre carbon footprint in our lifetime, the industry needs to embrace innovative green technologies."
