Power will become the single most important factor in data centre operating costs as more space is taken up with IT equipment and overall power consumption rises, a report from consulting firm BroadGroup warns.
At the same time, the report noted that the incidence of carbon concerns has increased since 2006.
BroadGroup said that a number of smaller providers had entered the market with a 'carbon neutral' data centre offering as a form of differentiation.
But the principal concern across all companies surveyed is the soaring cost of energy. The reduction of energy usage and adoption of green policies is now a top priority in the IT environment.
Blade servers, once considered a solution, are typically running at below full capacity with no more than 20 blades being put into a rack owing to cooling limitations.
The survey concluded that it is unlikely that a standard data centre design will be able to improve on the 1.0 unit of power to 0.6 cooling ratio unless there is a change in technology.
However, new types of energy storage and power hold the promise of further efficiency gains once their commercial potential can be proven.
