Organisations are spending 80% of the data centre budgets on maintenance, says Chris Ingle, research director at analyst group IDC. And data centre maintenance budgets is set to grow as companies invest more their infrastructure. Its a simple equation: more infrastructure means more maintenance. His reasearch shows that data centres in the UK are an average of 9 years old. Because they use older equipment, its difficult for them to integrate the latest kit into their infrasctructure. Virtualisation, however, is helping datacentres keep costs under control, with 25% of company data centres virtualised by up to 70% or 80%.
