[Abstract]:Cloud computing data centers are made up of a large number of servers connected by high-speed networks. An effective energy saving measure is to maintain the number of active servers in proportion to the system load and switch the remaining servers to idle mode. Thus, the operation energy consumption and the switching energy consumption are generated respectively. In this paper, the problem of how to configure the number of active servers to minimize the energy consumption of data centers under the condition that the load in different service slots is known is studied. First, the NP mathematical model of the problem is established, then the characteristics of the optimal solution without switching energy consumption are analyzed. Finally, by eliminating the recursive process of integer dynamic programming, the optimal algorithm with polynomial complexity is obtained. The numerical results show that the optimal algorithm can ensure the minimum energy consumption and the smooth calculation process under different load trends.
