A formal approach to Information Lifecycle Management.

TL;DRAbstract

In this paper we present a framework for simulating Information Lifecycle Management (ILM) scenarios. The framework is derived from a formal approach to ILM which offers concrete mathematical terminology. INTRODUCTION Information Lifecycle Management (ILM) is one of the great trends in the context of information storage. It has its roots in hierarchical storage management (HSM), which was popularized with mainframe storage management strategies in the early 1980s. ILM is a process for managing information through its lifecycle, from conception until disposal, in a manner that optimizes storage and access at the lowest cost. ILM is based on the idea that in an enterprise there are different information with different values. The different information will be stored on different storage devices. The same principle is employed with ILM for storage systems. ILM manages information according to its value. Valuable information is stored on systems with high Quality of Service (QoS) [1]. The
