How I analyze user disk space with ShowSize

in Usage notes

“I use ShowSize as a tool to assist in the development of Excel Workbook Reports for our IT staff. The tool has also become valuable in the migration (virtualization) of our servers into an IBM Data Center running VMware Infrastructure and analyzing data at the multi-terabyte level.

At my most routine use, ShowSize allows me to investigate where data is hiding when a user reports a space usage problem, or when a fellow IT member wants to know where (and to whom) disk space is allocated on a particular server.

For analysis, I use ShowSize in gathering the size information of all data on our file servers and then exporting those scans into Excel where I can further analyze the data. For instance, getting the size data on top-level shares allows me to create folder-size comparison sets at the departmental and section (or building) level and reporting that into average and total amounts per server and location.

I also use ShowSize in analyzing NTFS ownership information on the data itself. Getting this information from our servers allows the creation of in-depth reports showing our users’ space utilization. When aggregating this information across servers (and across users) it allows me to create summaries on the lowest, highest, and average points of space utilization per user in our organization at the server, department, or section level.

Using the data gathered from ShowSize, I create reports on a regular basis for storage comparison or for specific projects. Since ShowSize works at any point between the server and user level it has become a key resource in analyzing our data. This allows us to plan future storage needs thus assisting us with expense projections for additional disk and backup hardware.”

Note from ShowSize support: The ShowSize report that William often uses is the Owners report. This report is available in the minimum 5 user license edition of ShowSize. The 5-user edition also supports saving of reports for subsequent viewing on any systems, even those not connected to the original system or its disks. The report viewer is fully interactive, allowing you to apply the filters or sorts on the collected data and to see any of the 7 reports in a tabbed interface.
