Executive Summary

The Celerra Data Deduplication feature adds to Dell NX4's impressive storage efficiency capabilities by intelligently reducing space usage and providing further storage efficiency. One can optimize the use of the existing storage environment for file system data through single instancing and compression. A combination of file-level deduplication and compression represents the best technique to provide maximum benefit for the resources consumed. When applied to file system data, one can expect savings in the range of 30 percent to 40 percent for typical file-share data. This feature builds on NX4's ease of use by providing a single-click option in Celerra Manager to enable deduplication for each file system. Celerra Data Deduplication also supports almost all NX4 features and works in accordance with maximum-supported NX4 limits.
