We recommend that you install the interface on the same computer as the source Data Archive and push data to the pi buffer subsystem (which sends data to the Data Archive) in order to reduce or eliminate arising from a network outage.

Place the PI to PI interface as close to the source Data Archive as possible

The source and target Data Archives are established in the interface's startup batch file. Whether the interface pushes or pulls data depends on where the interface is installed. From a performance standpoint, AVEVA recommends that the PI to PI Interface push data to the destination server and be installed on the same computer as the source Data Archive. The PI Buffer Subsystem should be enabled on the interface machine to push data to the destination Data Archive, thus reducing network outage issues. If it is not possible for the PI to PI Interface to be on the same computer as the source Data Archive, then it is preferable to place it as close as possible to the source Data Archive. If the interface is installed on the same computer as the destination Data Archive and pulls data then there is a greater chance for loss of connection issues.

Recommended option: Interface running on the source Data Archive, pushing data to the target Data Archive

Interface running on the target Data Archive, pulling data from the source Data Archive

Interface running on a separate node
