Data Center Server Energy Consumption Optimization Algorithm

Understanding, modelling and reducing data center power consumption is a complicated undertaking. Individual data centers are highly complex systems, with a number of interacting mechanical, electrical and computational subsystems. The paper presents an optimization algorithm which reduces the energy consumed by the informational systems by assign virtual machines to physical servers. This action is achieved taking into account the different degrees of freedom of the used resources. The considered problem is formulated as a mixed integer linear programming problem where all transfer functions, constraint functions and objective function are expressed under a linear form.
