There is little connection between corporate plans to introduce "green" policies and what is actually happening in IT departments, according to a survey of 800 datacentre managers by Symantec.

The "Green Datacentre" survey showed that although 56% of organisations have a green policy in place, only one in seven have implemented a green datacentre.
"One of the main reasons for this disconnect is the fact that datacentres are run by IT managers who do not see the power bills," said Alex Rabbets, managing director at Migration Solutions.
Rabbets said there was a need for a much more holistic approach to green datacentres, where managers of IT, facilities and finances all work together on a co-ordinated programme to reduce environmental impact.
"The problem is everyone is working in their own silos, and while individual initiatives such as more power efficient servers are good, they are not joined up enough to have an overall positive effect," said Rabbets.
He said that with 3% of UK power being used by datacentres, and despite various green initiatives, the overall power consumption by datacentres continutes to increase.
"Business has got to stay ahead of regulations and the only way to do that is by taking action now to look at the overall picture and co-ordinate efforts to measure, benchmark and reduce power consumption," said Rabbets.
He said although saving the planet was the long term goal of making datacentres more power efficient, companies could save up to 20% in costs by looking beyond the servers at the whole operation.
"Many do not realise that they need to look at things like power efficient lighting, using lighting only when necessary, consolidating and rationalising storage, not running test and development environments when not needed, and a bunch of other things," said Rabbets.
