A combination of under utilisation of existing datacentre server and storage resources and increased demand means one third of UK ICT departments predict they will run out of physical space for data storage within 12 months and 60 percent expect to run out within two years.

That's according to a survey conducted by Computerworld UK on behalf of environmental charity Global Action Plan

The survey found that two-thirds of IT departments surveyed have already used up 75 percent of their datacentre floor space.

Furthermore, most enterprises under-use their existing data storage facilities despite nearly 37 per cent of respondents saying they store all data indefinitely. A fifth - 20 percent - only use under 30 percent of their server capacity. And 36 percent of respondents do not know or cannot measure how much of their server estate is being used.

The research report said the figures revealed an alarming attitude towards the environmental impact of datacentres and the unsustainable nature of current server and storage strategies.

The research surveyed 120 IT professionals with combined budget responsibility of more than £475 million.

Global Action Plan launched the survey as part of a larger in-depth report called The Inefficient Truth to politicians environmental and IT industry leaders at a special event at the House of Commons today. In the in-depth report, the charity detailed technology strategies that could improve datacentre efficiency, such as consolidation, intelligent datacentre design, dynamic cooling and server virtualisation.
