Storage management cost is a significant fraction of the total cost of ownership of large, enterprise storage systems. Consequently, software automation of common storage management tasks so as to reduce the total cost of ownership is an active area of research. In this paper, the authors consider a policy-managed storage system a system that automates various management tasks and focus on the problem of the storage allocation techniques that should be employed in such a system. They study two fundamentally different storage allocation techniques for policy-managed systems: narrow and wide striping.
