SQL Server requirements for System Platform components

SQL Server is required when any of the following System Platform components are selected for installation:

• Application Server Galaxy Repository (GR)

• Historian Server

• System Monitor Manager

The prerequisites installation workflow diverges if SQL Server is required but not already installed, and you will be prompted to install SQL Server during the installation. At this point, you have a choice of having System Platform install SQL Server 2022 Express Core automatically, or exiting System Platform installation and installing SQL Server before proceeding.

• If you are installing a small system (less than 25,000 I/O), you can allow System Platform to continue installing, and SQL Server Express Core will be installed during the System Platform installation process. You do not have to install SQL Server Express Core separately.

• If you cannot use SQL Server Express due to your system requirements, exit the installation program and install a supported SQL Server version. Resume System Platform installation after you have installed and configured the supported SQL Server version.

To see if one of the SQL Server-required components is selected for installation, click the Customize Installation checkbox and scroll through the product/component list. In some cases, you can deselect the SQL Server-dependent component, if you decide that the component is not needed for the product or role you are installing. For some roles and products, you will not be able to deselect the component and still have the functionality required for that particular role or product.
