Utilization Strategy

Power provision is coming to be the most important constraint to data center development, how to efficiently manage power consumption in the data center is urgent. For solving this problem, we designed the Request-Response Hierarchical Power Management model (RRHPM) for data center and analysed its performance in our latest work. Because failures are quite common in current data centers, in addition to performance, the fault-tolerance is another important metric of power management system. In this paper, we further explore the fault-tolerance of RRHPM for the data center. Numerical results show that the Equal Utilization Strategy has higher fault-tolerance than popular Equal Degree Strategy.

Utilization Strategy

Power provision is coming to be the most important constraint to data center development, how to efficiently manage power consumption according to the loads of the data center is urgent. In this paper, we provide the Request-Response Hierarchical Power Management (RRHPM) model for data center, and based on queuing theory, analyse the performance and constraints of two strategies hierarchical structure implement of RRHPM. Numerical results show that the Equal Utilization Strategy has less average response time, can manage more service nodes with the same response time threshold, and require less power management nodes than popular Equal Degree Strategy.
