The cost of managing IT infrastructures is growing four times faster than IT hardware spending, according to HP.

Energy is now a top concern for companies running data centres. If this problem is not addressed, companies will face power shortages in the future. For this reason, HP is offering its customers more efficient ways to manage their data centres and energy consumption.

"63% of the energy that comes into a data centre is used for cooling," says HP. "Some servers and racks do not need to be cooled as much as others, but they are still allocated the same cooling resources. This is a waste of energy."

HP's Dynamic Smart Cooling' strategy is designed to automatically monitor and control cooling resources in a data centre. With DSC, a series of sensors is placed on each server rack to measure the temperature. These sensors report to the control module, which can prompt the air-conditioners to reduce or increase cooling, as and when needed. DSC can save 15% to 40% of costs spent in cooling, HP claims.

HP's Adaptive Infrastructure strategy promotes low-cost, flexible and automated IT environments that can scale according to business needs.

HP also offers the Insight Power Manager, an integrated energy monitoring and management application that enables centralised control of power consumption in servers. "It can produce real-time reports on the power usage of all your servers in a data centre, so that you are aware of exactly how much power each server is consuming," says HP.

Thin provisioning enables a company to allocate storage space to servers as and when it is needed. A company need not be wasting energy to power up storage that it does not yet require.
