Introduction to Squeeze Aggregation (12/18/18)
The Squeeze Aggregator enables a user to scan multiple servers/volumes and estimate a combined dedup and compression ratio for all volumes scanned. This document describes how to use the Squeeze Aggregator.
The major steps are:
- Execute a Squeeze scan on each server that you wish to analyze. The output is an encrypted file with the extension .SIOKIT
- Upload the SIOKITs to Live Optics
- Logon to the Live Optics portal
- View the consolidated dedup and compression estimate for all uploaded SIOKITs
This example demonstrates running Squeeze on three servers and then viewing the aggregated results on the Live Optics Portal. The target platform in this example is XtremIO.
- The user first downloads the Squeeze collector from Live Optics. See Appendix 1 for instructions on this step.
- The user then opens a command window with administrative privileges and executes a Squeeze scan on each of the servers. The command is:
Squeeze –XtremIO –dedup C:\Users\wolfeb3\Temp ~Server_1
- The command is repeated once for each of the servers.
- The intermediate results are stored on the user’s host in an encrypted file with the extension .SIOKIT. The three files created are:
- Next the user uploads the SIOKITs to the Live Optics Portal. The upload command is:
squeeze –upload 0.siokit squeeze_Server_2_XtremIO.1.siokit squeeze_Server_3_XtremIO.2.siokit
Alternatively, if the files are located in the same directory:
Squeeze –upload *.siokit
- The Squeeze uploader asks the user to confirm her identity and then uploads the SIOKITs.
- The user then logs on to the Live Optics portal at the URL: http://www.liveoptics.com. The most recent project is the aggregated Squeeze results.
Interpreting Squeeze Results
The screen shot below shows a typical output for an XtremIO Squeeze scan. Outputs for VMAX/PowerMax are similar. The upper right of the screen shows a bar chart for illustrating the capacity required for the customer’s data. The bottom of the chart shows deduplication and compression ratios. Clicking on the Volumes Tab shows the data reduction achieved for each volume scanned.

Detail of the Data Reduction bar chart. In this example, the disk has a total capacity of 235.42 GB of which 226.79 GB is used. After deduplication and compression (deduplication is always done first), the required space is reduced to 167.33 GB.
Detail of the Ratios and Capacity section. Here we see the total used capacity and the space required after data reduction. The deduplication and compression ratios are listed as well as the overall data reduction ratio.
Click the Volumes tab to see the size and data reduction for each volume scanned. Note that in this example, only one disk was scanned.
Appendix 1: Downloading the Squeeze Collector
- Access the Live Optics portal (https://www.liveoptics.com ) and login with your account credentials.
- If you have never logged into Live Optics before, go to https://www.liveoptics.com/register and request your account be created or contact your Dell Sales Team and request they register you to the Live Optics portal.
- Goto the Squeeze Utility download page by first selecting “Collectors” and then select “Squeeze”
- Squeeze is supported on both Windows and Linux platforms. Select the appropriate platform and click to download the utility.
- Click on the “Windows” option and download the Squeeze .ZIP file. The .ZIP file contains an executable image of the Squeeze Utility and an End User License Agreement (EULA).
- Open and read the EULA. By executing the Squeeze utility, you are accepting the terms and conditions in the EULA.
- Copy the Squeeze utility to a directory on your computer. Live Optics recommends that you create a new directory (i.e. C:\Program Files\LiveOptics) and modify the Windows Path variable to include the new directory.
