| Sumario: | The fear experienced by data center administrators presents an ongoing problem due to the low percentage of machines that they are willing to switch off in order to save energy. This risk aversion can be assessed from acognitive system. The purpose of this paper is to demonstrate the extra costs in curred by maintaining all the machines of a data center executing continuously for fear of damaging hardware, degradating the service, or losing data. To this end, an objective function which minimizes energy consumption depending on the number of times that the machines ares witched on/off is provided. The risk version experienced by these data center administrator scan be measured from the percentage of machines that they are willing to switch off. It is shown that it is always the best option to turn off machines in order to reduce costs, given a formulation of the cognitive aspects of the fear experienced by data center administrators. |
