System Sizing Guidelines

The following table provides guidelines for hardware configurations suitable for System Platform 2023 software based on the size of the application. These guidelines are subject to the limitations of your Windows operating system, and if applicable, to the SQL Server edition (Express, Standard, or Enterprise). See the AVEVA GCS Technology Matrix for supported versions of Windows operating systems and SQL Server.

• We recommend an HD display resolution for engineering tools such as the Integrated Development Environment (IDE).

• A Windows Server operating system is required for large installations with more than 50,000 I/O per node.

• SQL Server Express is not supported for installations with more than 25,000 I/O per node (small installations only).

• 32-bit operating systems are no longer supported. Installation is blocked on unsupported operating systems.

• 32-bit versions of SQL Server are no longer supported. Installation is blocked when an unsupported version of SQL Server is detected. The unsupported version must be deleted and then a supported version installed before installation can proceed.

  The following guidelines are provided for reference only. The system configuration required for your application will depend on multiple factors, including but not limited to the size and complexity of the application, and the features and components used.

  1) To calculate the number of logical processors: multiply the number of physical cores by the number of threads each core can run. A four core CPU that runs two threads per core provides eight logical processors. The terms "Hyper-Threading and "simultaneous multithreading" (SMT) are also used to describe logical processors. 2) SSD drives are highly recommended. 3) In redundant environments, increase CPU and RAM to maintain a maximum of 40% typical resource utilization. 4) For optimal performance of all-in-one nodes, a high clock speed (>2.8 GHz) is recommended. 5) For Application Server platform nodes, it is recommended that you deploy no more than two AppEngines per logical processor (typically one primary AppEngine and one backup). 6) For large applications on all-in-one nodes, dual XEON processors are recommended.
