Executive summary

Data growth in the Enterprise world is enormous. In the traditional system, to achieve high performance needs, all the data must reside in the high performing disks irrespective of the access pattern. However, all the data residing in these disks may not be accessible all the time as a result high performing disks are used inefficiently. To avoid this, many storage vendors have adopted a concept called tiering . Tiered storage consists of different disks that differ in cost, performance, and capacity. Tiered storage enables placing the data in the right tier based on usage pattern, performance, and cost requirements but it requires a manual intervention to move and reformat data.

In Dell™ Compellent™ storage systems, this process of tiering is automatic. You get the benefit of automatic tiering by enabling data progression, which automatically moves data to the right place at the right time based on usage pattern and performance needs. This paper emphasizes Dell Compellent Automatic Tiering and provides the cost and performance benefits that are achieved using the automatic storage tiering features like Fast Track, Data Instant Replay, and Data Progression for Oracle® database OLAP workload.
