Concerns over data centre energy use
03 Oct 2008
The spread of volume servers, which now cover around 90 per cent of the installed base, could be responsible for the increase in the amount of energy required to run a data centre, research has suggested.
Between 2006 and 2007, the amount of power needed rose by 13 per cent, IDC found, adding that data centrepower consumption exceeded 40 TWh in 2007, although this is estimated to reach 42 TWh by the end of 2008.
Giorgio Nebuloni, analyst for European systems and infrastructure solutions at IDC, blamed the increase in volume servers and the fact that often IT staff are not responsible for budgets so may not realise how inefficient a system could be.
The cost of the increase in 2007 was €4.4 billion (£3.4 billion), IDC claims, adding that this is equal to 40 per cent of the new hardware capex.
But it could be said firms do realise that green action is needed and large organisations such as Google have built energy-efficient data centres.
And Heidi Biggar, director of product marketing at Virtual Iron, tells Virtualisation that a Massachusetts-based health care provider replaced its physical server environment with one virtualised server environment, cutting its IT budget by ten per cent every year, for two years, since the deployment.
