A Dynamic Load Balancing Approach Based on the Remaining Storage Capacity for Mass Storage Systems

摘要

In the mass storage system, load balancing becomes a key issue. The people proposed the load balancing method in the past only to consider the load of the node. In this paper, we propose the load balancing method based on the remaining storage capacity. The method considers the load and the node's remaining storage capacity of the node. By analyzing the load-control model, this paper presents a hybrid control model. Each level uses the different balance strategy. The model can timely spread the load. To collect information consumes few resources. The simulation results show that the approach can markedly reduce the overall response time and balance the global load.
