ISE Deployment

[nupur jain]

I have a customer who has 8 PSN Nodes running along with the PAN and MNT running on the same appliance! 

The CVD however mentions that there should only be 5 PSNs in the deployment 

What are the negative impacts of having 8 PSNs in this scenario 

Impact in terms of perf degradation, latency issues etc!

It difficult to say as it is not a tested & validated configuration. Please refer to the following Cisco Live presentation for ISE scale guidance.
