This paper addresses the problem of Data Centers (DC) energy efficiency by proposing a proactive optimization technique to schedule the day-ahead DC operation to minimize the operational cost. The proactive optimization technique is formalized as a Mixed Integer Optimal Control Problem, known to be NP-hard. Because the time needed for solving this problem by some of the gradient-based solvers depends...
This paper addresses the problem of Data Centers (DC) energy efficiency by proposing a complex consolidation technique which aims at optimizing the DC operation such that both the IT equipment power consumption and cooling system power consumption is minimized. The paper presents a thermo-electrical DC model that defines the relation between the server utilization due to VM deployment, the server...
