About Information Lifecycle Management

An important concept in the context of storage networking is Information Lifecycle Management (ILM). The idea is to ensure a match between data and an appropriate storage product. As information ages, it passes through a continuum in importance, from current work to archived projects that you never expect to work on again. A system’s storage should reflect the changing nature of data.

For example, current projects may be on storage that is both high-performance (so that you lose no time working) and high reliability (so that you don’t miss a deadline due to equipment failure). Older projects, on the other hand, may not need the high performance because they are not under active development, but they may need to be accessed occasionally.

As time goes on, you may not even need the projects to be available immediately; they need to be reliably stored, but it may be acceptable to have access times of up to a day to bring the material back online.

Managing information’s lifecycle can be handled several ways. Often, a manual process moves completed projects into a designated target. You can also use an Xsan system, which can spread folders across different storage types, or affinities. If you use an Xsan system, ADIC’s StorNext Storage Manager can help you set up policies for a lifecycle management workflow. You can define service levels for different classes of data, and automate data placement and protection objectives.

Xsan can act as a client to the StoreNext SAN volume and mount the volume. From a user’s viewpoint, the volume looks and behaves like a standard Xsan volume.
