ISE - Large Deployment - 50 PSNs

GRANT3779 — Wed, 12 Jan 2022 09:08:06 GMT

Hi CSC,

Can an ISE "large" deployment have up 50 PSNs (max) regardless of the VM sizing? Quite difficult to get an exact answer via Cisco documentation. From what I can make out the only requirement to being able to scale like this is that the Admin and MnT personas need to be on their own servers.

Pre - 3.1 - I'm assuming if I had "medium" VM licenses I could still scale up to 50 PSNs following the large deployment model?

3.1 + - With the common VM license, a company could base the VM resources on their needs and still be able to scale to 50 PSNs if following large deployment model?

I guess the ultimate question is - Does following the large deployment model (max 50 PSNs) have any dependency on the actual size type of VM license / resources? With 3.1 having a one tier common license however, I'm thinking the ability to scale to 50 PSNs is based on the Admin / MnT personas being split from a design POV?

yes 50 is still the case as per the cisco deployment model

50 can be an size, so you need to looking sizing guide based on the session.

If you requirement is more than 50X large and more, this is quite a big investment, this can not be over community discussion.

contact cisco partner to offer you different services how you can split the traffic dependss geo location and different deployment methods
