Just a quick drop on the Data Reduction Tool that we use in the field to help estimate how much storage customers will save by running their data on our A9000 All Flash Array. This system (not SSDs) is based on the XIV Grid architecture and is available to customers since this past summer. 

One of the things that many of our customers tell us is our competition is out offering silly data savings only based their word. IBM has for the past 5 years giving customers a real estimate on their compression savings using our compression estimation tool within 5% with out change to your code or storage system. Now we have the ability to run the tool on your data for savings on our compression, deduplication and pattern analysis. 

This tool is downloaded from the IBM site and run on the host against the storage lun/volume. At the end you will be able to see the savings broken down in those three categories plus how much could also be saved using thin provisioning. The tool is CLI based and should be run by an admin with proper access.

All said this tool is the best thing out there to really give customers an idea of true savings. For more information please follow these link below

For more information about the tool or help running it feel free to contact me or your local IBM Storage Engineer.
