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.

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.

Conflict Escalation

Conflicts can be dangerous or may even benefit a relationship, depending on how they are resolved. Because conflict creates strong emotions, emotions are not suitable as a basis for constructive problem solving. Conflict escalation rarely benefits a relationship, especially if it creates selfishness, stubbornness, and withdrawal from relationships. What's worse, conflicts can lead to physical disputes and actual violence, a community can work together, but it can be that at other times the community that has worked together can turn into social conflict. Conversely, people who initially conflict can change to work together for a certain time. For that social processes that occur are very dynamic, these conditions are very dependent on the power management model that runs in the community concerned thus interpreting the conflict based on the causes of conflict are: specific behaviors, norms and personal roles and dispositions. Conflict can also occur in the name of religion, caused by several factors including: superficial religious knowledge, fanaticism, religion as a doctrine, symbols, religious figures, history, fighting for surge.
