The XtremIO Data Reduction Estimator is a stand-alone tool that can be used to determine the exact deduplication ratio for specific volumes. The tool supports multiple platforms and environments, and can be run on a drive or mount point, raw device or a folder, as targets. The Data Reduction Estimator performs a read-only scan, then analyzes the content in a similar fashion to an XtremIO storage cluster, and reports the exact deduplication savings. Running the tool can take an extended period of time, depending on the size of the data set scanned and the throughput provided by the server, and the type of underlying storage device.

The tool can also scan multiple targets in parallel, and reports the dedup rate per target as well as the global deduplication across all targets scanned. The data deduplication ratios are directly proportional to the volume of redundant data in the server. For example, if there are more repetitive data in the database or in the server similar to data files or other files ,  higher ratios of data deduplication will happen. If there are multiple operating systems, the data deduplication ratios will get reduced.

The XtremIO Data Reduction Estimator tool has multiple distributions (as you can see below):





The windows installation EXE file allows you to choose between the full install the XtremIO Data Reduction Estimator or just a one-off install, in which case all files are immediately deleted upon exiting the session.


To install for Windows:

  1. Double-click the file called ‘XtremIO Data Reduction Estimator.exe’.
  2. Select either:
    • Run the application as a stand-alone — deploys the application, which then starts within a couple of seconds.


    • Install the application — deploys the application and creates shortcuts on both the Start menu and the Desktop.

Once the installation has completed, click either shortcut to run the application. Once started, the Data Reduction Estimator tool scans all local drives and the main view is loaded.


Defining Data Reduction Estimator Targets Data Reduction Estimator

  • Add scan targets by clicking + .
  • Raw devices are added by default.
  • Add a drive or a mount by clicking zz3.pnglocated adjacent to the ‘plus’ button. A drive or mount can then be selected from the resulting drop-down list.


Device Options

The Data Reduction Estimator does not directly support network shares. However one can mount network shares to the operating system, and then add the operating system as a folder target. Results differ only by the unreadable metadata.

Memory Allocation

The amount of memory and read bandwidth to be used by the Data Reduction Estimator can be restricted as per user’s requirement. The maximum memory displayed is the maximum amount of memory allocated to the process by the operating system.  A memory limit higher than the maximum can be set. Once it is detected, the Data Reduction Estimator prompts to re-launch. Relaunching is necessary in order to increase the amount of memory allocated to the process.

Running the Data Reduction Estimator

After adding scan targets, limiting memory and bandwidth, the scan can be started.To start the scan:

  • Click zz5.png


A folder scan target may take some time to start as it needs to scan all files and/or folders within the target. During the scan, current results and progress are displayed in the results table, located in the lower section of the screen(displayed above).


When the process finishes (for all scan targets), an additional results row is added to the table, showing the global results across all scanned targets.




This tool is an awesome tool which can be used with the XtremIO storage to get the following information.
