Constructing Storage Capacity Migration Policies for Information Lifecycle Management System

To maintain very large amount of increasing dataset, it is critical to enforce the data migration policies across different levels of storage devices. The challenge is to achieve both low storage cost and response efficiency. In this paper, we will investigate the factors for this problem, then adapt dynamic programming technique, and design appropriate ECA trigger rules. From the conducted experiments, our methodology provides a feasible solution for this important kernel issue of the Information Lifecycle Management (ILM) problem.
