ISE | Virtual Instance Sizing

[hanguye3]

Hi bros,

We have customer with 6000 active users and they consider to choose VM instance or physical appliance to deploy. i have sizing question on the VM Instance and need your advice on the queries below:

- Cisco ISE Virtual Machine Small can have 16GB RAM and up to 6 CPU cores: can it handle 6000 active users?

- can we install this VM with more resources like 32Gb RAm and more CPUs?

Highly appreciate for any quick response.

thanks in advance.

Br,

The easiest method would be to have the customer use the OVAs that are available at cisco.com.  For information on concurrent endpoint count support per appliance size, check out the performance and scale guide:
