CitectScada 2018 R2 Clustering Scenarios

Steve

Hello,

I am hoping to get some assistance with clustering. I am trying to do some testing before fully deciding if and or how to cluster our system. We have a large alarm database and I have been told that putting our "SOE" events in their own cluster would be beneficial. 

I have done some testing and created a new cluster and added the SOE alarm records to the new cluster. The issue I have now is that the SOE digital alarm records are based on variable tags that I need to keep in the original cluster. 

Am I able to have a digital alarm in a different cluster than the variable tag its triggered off of? 

Hoping to get any help or advice possible.

Thanks,

Steve

  • Thanks for the information! I will have to update the ini file with those additions. We have roughly 90,000 alarm tags. One of the challenges is that any clients that have more than 4 monitors really start to struggle with performance. We have had to make other changes just to ensure the clients do not get overwhelmed.

    We are still on the fence with how to improve performance for these clients. As mentioned one suggestion from support was that the clients will have difficulty updating alarms with an alarm database that large and clustering is an option to reduce it . We have seen a direct correlation between alarm server performance and multi-monitor client performance. Any suggestions beyond clustering or do you believe clustering would help performance for multi-monitor clients?

    Thanks again!
