PI OPC DA - OPC Server Failover

Hi All


I have a query on PI OPC DA Interface - OPC Server Failover. e.g. Primary OPC server OPC01 and Secondary OPC server OPC2.


I have around 10K tags which can collect data from OPC01 and OPC02.  Currently configured 5K on each OPC01 and OPC02 . If OPC01 is stopped then 10K tags should be collecting from OPC02 server. Once OPC01 server is online then 5K tags should be collecting OPC01  and 5k tags from OPC02. We dont want a situation where tag count increases then it overloads the OPC server everytime during failover and would like to know the best configuration to avoid overloading.


Please suggest.


Thanks, Lal
