ISE Sizing with Mix Appliances Models

I’m having difficult to sizing the design with mix appliances models (SNS-3515 and SNS-3595). Could you please help me to size (max concurrent sessions per site) for both designs attached?

Re: ISE Sizing with Mix Appliances Models

It's generally not recommended to deploy Admin/Mnt on 3595 and PSN on 3515.  The PSNs are actually the workhorses of the deployment as they service all the RADIUS traffic.

When co-locating the Admin and MnT personas on a single node, the max concurrent sessions for the deployment are 20,000 on SNS-3595.

The SNS-3595 has 8 CPU cores running at 2.6GHz and 64GB RAM.

The SNS-3515 has 6 CPU cores running at 2.3GHz and 16GB RAM.

The max concurrent sessions for a SNS-3515 deployment are 7,500.  You MIGHT eke out a total of 10,000, but this is not a design that is tested or recommended so no official numbers will be available.

Re: ISE Sizing with Mix Appliances Models

Charles, why is not generally recommended to deploy Admin / MnT on 3595 and PSN on 3515?

If sessions are scaled correctly
