Due to the high performance and reliability compared with single big disk systems, RAID systems have been the dominant products for back-end storage systems since they appeared in the late 1980s. However, the problems of disk failure, reconstruction time and contention for the shared interconnection medium have limited the scalability of modern RAID systems.

In order to address the aforementioned problems to meet the scalability demands of RAID systems, my PhD proposal presents two objectives.

1. building simulation models of RAID systems in HASE environment and studying the scalability of RAID systems, and
2. developing a storage system simulator in HASE environment.
