ISE 2.4 PSN Dedicated PSN Max Connections

[mcavinat]

Hello folks,

This was an easy information to find in old Installing Guides but has been removed since then.

1) Considering a dedicated PSN (35xx), what is the max devices that it supports?

I've seen documents saying a 3515 after 2.1 can support 7.5k and 3595 can support 40k but haven't seen that for ISE 2.4.

2) This used to be public on the Install Guide (NW Deployment in ISE). On 2.4 is not there. Where can I find this public?

Thanks

I'll admit, it's not as straight forward as it could be for dedicated deployments. It is covered in the scaling guide.
