ISE scaling question for 400k endpoints

Hi all,

quick question about scaling with ISE 2.1 and 3595-Appliances: According to documentation a 3595-Appliance can serve up to 40.000 concurrent active endpoints. So if I had a pure centralized deployment (all in one datacenter) and if I had perfect distribution of the sessions 10 PSNs would be (in theory) good to serve 400k endpoints. Practically, we have to consider unequal distribution of sessions and redundancy as well of course.

Am I right with this assumption? What I would like to know if we can count on linear scaleability at that point.

Thanks in advance.

Roland

This should be done behind Load Balancers to allow more control, ease of deploying more PSNs, ability to take them offline for maintenance, also will help with redundancy for N+1 scenario

I don't understand your linear question
