So if you are looking at trying to trim costs and stuff more gear in the Datacentre than is physically possible then this might also be a useful way of "getting more out of less"? ;-)
HP adds thermal mapping to energy-saving services
Knowledge of air-flows in datacentres can lead to greater efficiency, vendor says
HP has added thermal mapping capabilities to its datacentre assessment services that show customers how they can potentially save between 10% and 45% on energy costs by using cooling systems more efficiently and optimising datacentre design.
HP Thermal Zone Mapping uses technology developed by HP Labs to create a three-dimensional model of how much, how often and exactly where air conditioners are blasting systems with cold air. The model, HP says, will help datacentre managers better arrange systems and other resources to optimise the use of air conditioning.
The company adds that when Thermal Zone Mapping is coupled with HP’s Dynamic Smart Cooling (DSC) products, customers can save up to 45% on energy costs spent on cooling.
