Hardware Specifications

The following hardware specifications are recommended for the Workflow engine:

  • A minimum of 20 GB of free disk space

  • At least 16 GB RAM memory


    The memory should increase based on the type of workflows that you plan to deploy and run. For example, if your workflows have a large number of tasks and a high level of complexity, you might need to increase the memory to optimize the Workflow engine performance.

    The Workflow engine includes the SQL Server software. The software installation requires 30 GB of disk space for the Microsoft SQL Server application and database and 20 GB of temp space.

    In the future, you might need to provide additional space (several GB) to allow for database growth.

Database Engine

Microsoft SQL Server 2016 Standard Edition is automatically installed during the installation of the Workflow software. If you have Microsoft SQL Server 2012 Enterprise Edition already installed in your environment, the Workflow Engine will use the existing SQL Server.

For more information, see Database Engine under System Requirements - CommServe.

.NET Framework

.NET Framework

Microsoft .NET Framework 3.5 Service Pack 1 and 4.6 are required and are automatically installed.


For .NET Framework 3.5, if the server is Windows 2012 or higher, the role is only enabled during installation if the machine has an internet connection. If there is no internet connection, you must manually enable the role.

The File System Agent is installed automatically during the installation of this software component (if it is not installed already). To review the system requirements of the File System Agent, see System Requirements - Microsoft Windows File System Agent.
