Storage Tiering Explained

Research from the Enterprise Strategy Group (ESG) indicates that tiering ranks in the top ten planned storage investments for 2011. As reported in this Network Computing article, storage tiering, the act of placing different data on various types of storage media and systems, is a hierarchy dependent on many factors.

"Factors affecting where data is stored include: the importance of the data in terms of performance, retention, or business value; the differing levels of service needed from users, customers, applications or business units; and the availability of capacity and management resources and funding available. The report includes analysis of 23 vendors, although that is only a subset of the total market, notes Peters, and breaks down the market structure into five main segments: array-based migration, array-based caching, file system-based, software tools, and archive emphasis."
