Thin provisioning and data deduplication are strategies for reducing the growth rate and space consumption of new data or finding more efficient ways of storing it. These strategies must be combined with addressing unnecessary data storage in order to fully utilize existing assets. The largest container of unnecessary and obsolete data is unstructured data.

Email is the biggest unstructured information pain point today and a top target for data reduction via archiving. The Radicati Group estimates that the volume of email will increase by 30 percent from 2006 to 2010. Although storage costs continue to fall on a per-unit basis, email is often stored many times in the email server, on the user’s PC, in a Microsoft Exchange or IBM Lotus Notes file, on file servers, saved in SharePoint, and in backups. Because of the excessive storage consumed, the cost of power and cooling is also commensurately higher.

During periods of economic growth, organizations may be tempted to take the “quick fix” to storage management problems. The incremental cost of adding storage is relatively small and can be absorbed by the budget. Such a short-cut may facilitate faster project roll-out, but it also leads to underutilized storage. Many organizations operate at only 30 to 40 percent utilization. According to InfoPro, the average is 35 percent.

Accurate storage allocation is difficult because data growth rate information is incomplete or unavailable. Consequently, storage allocation does not correlate to consumption. New applications, with no historical trend data, receive storage allocation on a “best estimate” basis. If the allocated capacity is too high, then the excess capacity may languish unused for the life of the array.

Needless spending is the primary consequence of benign neglect. Having an array only 50 percent utilized is like paying...
