InfoWorld has a special report: “Information lifecycle management turns traditional storage on its head, separating information from raw data and storing it based on its business value.”
The current darling of the storage industry, ILM is based on two simple concepts. First, not all information has the same value to the organization. Second, whatever value information has tends to change over time.
If these assumptions are true, then why apply the same level of expensive storage, management, and protection to all information in an enterprise? By moving less-valuable information to less-expensive storage and applying appropriate levels of protection to each storage tier, companies save money and reserve high-end resources for the information that demands them.
The result: Mission-critical systems are less bloated, more stable, and better performing. Backup windows shrink, storage runs out less often, upgrades are less frequent, and the overall cost of storage and storage management drops.
