Buffering and high availability

In high availability environments, we recommend using n-way buffering to protect against data loss. With n-way buffering, the buffering service queues data independently to each server in a Data Archive collective.

Starting with version 4.3, PI Buffer Subsystem can buffer data to multiple servers and collectives. It also comes with Buffering Manager, a new tool that provides step by step buffering configuration, including upgrades from API Buffer Server to PI Buffer Subsystem. These improvements are particularly helpful for high availability environments.
