ISE 2.6 Sizing

[JSS73]

I have read the sizing docs and watched the Cisco Live presentations, but I am still confused about the number of active endpoints, total endpoints, total active sessions etc. per deployment and per PSN.

If I have the following ISE 2.6 deployment all running on 3655, how many sessions can I have? I am seeing 25K per deployment then I read 50K per PSN, so I don't know what is the correct value.

- 1x PAN(P) + MnT(S)
- 1x PAN(S) + MnT(P)
- 4x PSN

Thanks
