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 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:
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
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.
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:
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.
