* Functionally flexible. Because the information needs of an organization will evolve and grow over time, the demands placed upon an enterprise storage system will change over time. In order to extend its useful life and reap the greatest return on the investment placed in the system, enterprise storage must be able to be re-deployed from its original purpose to a newer purpose providing a new function within the information infrastructure. For example, a system may start off providing storage to a legacy mainframe application that eventually gets retired so that the system then can be re-deployed to provide network attached storage for a web environment.
