Load balancing scheduling algorithm for storage system based on state acquisition and dynamic feedback

摘要

A load scheduling algorithm for the virtual server cluster which is suitable for the storage system is proposed to solve the problem of uniform load distribution of the current virtual server cluster, according to the characteristics of the storage system. This method, which analyzes the selection schemes of each index's weight, is based on the real server's state collection feedbacks periodically to the load balancer to make decisions. The result of experiment shows that this algorithm can make the external response performance (time to last byte) of the cluster system reach a higher level, and make the internal load performance of system (balance of disk usage) reach a more balanced state.
