Hi,
Got a customer considering upgrade to ISE 2.6 using 'Small' VMS equivalent to SNS-3615 spec. Approx 20,000 total endpoints, assumed to be not all concurrent.
Had been looking at 6-node cluster of 2xPAN, 2xMNT, 2xPSN but Install Guide(1) and Performance and Scale page(2) don't provide data for this type of deployment. Is that because it's not supported, or not recommended, or just not tested?
Alternative may be to go to 4 'Medium' nodes (SNS-3655) with Hybrid model (2 x PAN+MNT, 2 x PSN) but that's more resources than the 6x3615 which is unfortunate
