Overview of buffering versions

Select Tools > Buffering to configure buffering.

• If your computer is configured to buffer data using PI Buffer Subsystem 4.3 or later, the Buffering Manager window opens and shows a buffering dashboard. The dashboard shows information about the status of buffering on this computer. See Buffering Manager for more information.

• If your computer is not currently configured to buffer data, and PI Buffer Subsystem 4.3 or later is installed, you are prompted to configure PI Buffer Subsystem.

  • If you click Yes, the Buffering Manager window opens and shows the installation wizard, which helps you configure PI Buffer Subsystem.

    Note: PI Buffer Subsystem supports only one non-replicated server, or one or more member nodes of a collective. PI ICU verifies if buffering is enabled to more than one server or collective and prompts you for confirmation if there is a conflict. You may need to make configuration changes to support the subsystem.

• If your computer is configured to buffer data using API Buffer Server (bufserv), and PI Buffer Subsystem 4.3 or later is installed, you are prompted to convert to and configure PI Buffer Subsystem.

  • If you click Yes at both prompts, the Buffering Manager window opens and shows the upgrade wizard, which helps you upgrade from API Buffer Server to PI Buffer Subsystem.

• Regardless of your current buffering configuration, if PI Buffer Subsystem 4.3 is not yet installed, the Buffering Manager window opens.

Use Buffering Manager to configure, monitor, and troubleshoot buffering using PI Buffer Subsystem. PI Buffer Subsystem is recommended for applications connecting to PI Server 3.4.375 or later. Older versions of PI Server require API Buffer Server, as do some sites with custom solutions (for example, high availability solutions). See Buffering Manager for more information.
