Buffering and collectives

PI Buffer Subsystem 4.3 and later can buffer data to multiple independent servers, including those configured as PI Server collectives. For interfaces to use PI Buffer Subsystem with PI Server collectives, the Data Archive servers must be running Data Archive version 3.4.375 or later.

Caution: API Buffer Server does not detect and validate the PI Server collective configuration. As a result, API Buffer Server requires manual configuration whenever a collective changes. Also, because API Buffer Server results in compression at the Data Archive machine, archives at different servers in the collective could contain different records.
