Jama Connect User Guide

Resource sizing for application server (KOTS)

For optimal performance, estimate your application server needs before you install Jama Connect.

Requirements

  • Each node must have a minimum volume size of 200 GB. 256 GB is the recommended volume size. Increase this size based on the size of the assets that you plan to save in Jama Connect. We recommend that every node has the same storage space.

  • KOTS must be up and running before you configure the application settings in the KOTS Admin Console.

Important

To avoid performance issues, use the recommended requirements for horizontal scaling, rather than minimum requirements.

Use the following tables to help determine resources for the primary node of your application server.

Tip

Once you're up and running, you can monitor usage and adjust your settings as needed (see "Monitoring memory usage" and "Configure memory settings" in Jama Connect User Guide 9.17.x).
