Abstract

Cooperation between storage devices is an important aspect of autonomic storage system. By employing multiple distributed storage resources, storage system can greatly improve its performance. In this paper, agent-based methodology is introduced to build an autonomic storage system infrastructure. To select appropriate storage devices, queuing models are established to estimate the future storage device performance. A replica selection method and a data allocation algorithm are presented to gain an aggregate transfer rate according to the predicted performance. The results show that our models are useful for evaluating the mean response time of storage devices.
