One thing holds true in the modern
storage environment—data fills all available

IBM tiered storage management helps reduce costs and complexity

  1. 1. Simplifying storage lifecycle management IBM tiered storage management helps reduce costs and complexity One thing holds true in the modern storage environment—data fills all avail- able space. And as organizations across all industries are adding daily to the mountains of customer data, finan- cial records, e-mails, images and other electronic content, many are realizing that these heaps of data are actually driving every decision and process throughout the enterprise. Not all data is created equal, however, and deriving business value from infor- mation dispersed over many different sources means integrating, analyzing and optimizing heterogeneous types and sources of information throughout its lifecycle.

This helps lower manual intervention costs and reduces risks. By classifying and segmenting data into a multi-tiered structure, companies can create services and service level poli- cies that support each tier and leverage IBM storage software to not only struc- ture the tiers but also do operational management once the tiers are estab-Yet many companies are overwhelmed Increasingly, customers want to organ- lished.
