N-way buffering for PI interfaces

You can use a buffering service to control the time-series data flowing from a PI interface to Data Archive. When Data Archive is not available, the buffering service temporarily stores the PI interface data. Once the server is available, the buffering service sends the data to Data Archive in the proper order. To support Data Archive HA, you configure the buffering service to use n-way buffering. With n-way buffering, the buffering service queues data independently to each server in a Data Archive collective.
