Storage management mechanism for a scalable streaming media system

Streaming media is pervasive on the Internet now and continues to grow rapidly. A large scale streaming media system may demand thousands of disks tosatisfy both the bandwidth and storage capacity requirements imposed by thousands of concurrent clients. While performance has long been the focus of large scale storage systems research, manageability has become the dominant criterion in evaluating storage solutions, as the cost of storage management outweighs the cost of the storage devices themselves by a factor of three to eight. This paper designs and implements a highly reliable and available distributed media data oriented innovative Storage Management Mechanism (SMM) in a scalable streaming media system. Allheterogeneous storage resources across the system are aggregated as a single logical view which strikes a good balance between a distributed data storage and centralized storage …
