Select the buffer location

The buffer location is the folder containing the buffer queue file (or files) used to temporarily store buffered data for each Data Archive server if it becomes unavailable. When the connection is restored, PI Buffer Subsystem sends the data from the queue file to the server.

The Buffering Configuration pane shows the available drives and the available space on each drive. Use this pane to select the buffer location for all buffered servers that will receive data from this computer.

Note: For optimal performance and reliability, select a drive that does not contain the operating system or the Windows page file.
