Estimating Disk Space Requirements for Tableau Server

How to estimate free disk space requirements for installing and running Tableau Server depends on how you plan to deploy and use Tableau Server.


  • Tableau Server


In general, when estimating the amount of additional disk space to allocate for Tableau Server for day-to-day usage, you must consider whether or not extracts will be published to Tableau Server.

  • If you anticipate using extracts, Tableau recommends that you begin with a few hundred gigabytes (GB).
  • If you do not anticipate using extracts, you may only need around 50 GB to fulfill your usage needs.

Because usage scenarios can vary dramatically, review the following details to help you understand disk space requirements.

1. Publishing extracts to Tableau Server

If using extracts, consider the number of extracts that will be published to Tableau Server and the size of each extract. Test your needs by publishing several extracts to Tableau Server, and then checking the disk space. You can use this amount of disk space to help you figure out how many extracts will be published to Tableau Server over time as well as how each existing extract will increase in size.

2. Refreshing extracts

If using extracts, consider the space needed by the temp directory during an extract refresh. The temp directory, which is where an extract is stored to during a refresh, may require up to the square of the number of gigabytes of the final file size of the extract.

Note: This means you square the gigabyte value, you do not convert gigabytes to bytes and square that. For example, a 1 GB extract may take up to 1 GB of disk space (1^2), while a 12 GB extract may take up 144 GB of disk space (12^2) to complete the refresh.

3. Creating many workbooks

If using workbooks, consider the number of workbooks that will be published to Tableau Server. Individual workbooks tend to take up a small amount of disk space. However, if you anticipate thousands of workbooks being published, you may want to allocate additional disk space to accommodate those workbooks.

4. Logging

To assist with daily management and troubleshooting, Tableau Server creates log files as a part of its normal operations. Depending on the level at which the logging is configured, it can significantly impact the amount of disk space necessary on the Tableau Server computer.
