IT directors have been advised to increase efforts to reduce energy consumption as new evidence emerged highlighting the financial cost to IT departments of power-hungry hardware and soaring electricity prices. Gartner warned that while energy costs currently account for around 10% of overall IT budgets, the increased use of high-density blade servers coupled with rising electricity prices could result in power accounting for over half of IT budgets within the next few years.
"You can now put 10,000 servers in a datacentre without too many people needed to manage them," explained chief of research at Gartner, Steve Prentice. "So whereas you used to make datacentre decisions based on management costs and skills availability, now sensible firms are making those decisions based on energy. Google and Microsoft make no secret of the fact that their next generation datacentres in the US are being located in the Pacific North West because it puts them close to low-cost and reliable hydro-electric power."
