System Sizing Guidelines

The following table provides guidelines for hardware configurations suitable for System Platform 2023, based on application size. 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 Technology Matrix on the AVEVA Global Customer Support website for supported versions of Windows operating systems and SQL Server.

• An HD display is recommended for engineering tools such as the System Platform IDE.

• A 64-bit operating system is required, regardless of system size.

• A Windows Server operating system is required for large installations.

• SQL Server Express is supported only for small systems, that is, installations with less than 25,000 I/O per node.

• Pagefile.sys, the Windows paging file (also called the swap file or virtual memory file), must be enabled. The Windows default setting is enabled.

Definitions

In the table below, hardware guidelines for different types of System Platform are listed. Definitions for the terminology used in the table are:

Level (Minimum and Recommended)

Minimum level describes the baseline hardware configuration that will provide at least minimally acceptable performance for the role. Recommended level describes an expanded hardware set that provides improved performance.

Application Server Node

Application Server nodes, also called IDE nodes, are engineering workstations. These are used for creating, editing, and deploying objects.

Galaxy Repository Node

Galaxy Repository nodes, also called GR nodes, host the galaxy database once it has been deployed from an Application Server node.

Historian Server Node

Historian Server nodes host the AVEVA Historian. At its core, the Historian is essentially a Microsoft SQL database server.

Thin Client

Thin clients include include smart phones and tablets. In the context of System Platform, thin clients are platforms for web browsers and remote desktop sessions (for example, InTouch Access Anywhere clients).

Client

In the context of System Platform, clients are computers that can be used for development applications, such as remote IDE workstations, as well as for run-time applications like WindowViewer, AVEVA OMI ViewApps, and Historian Insight.

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.
