Hi all,
As part of an ACS migration to ISE, I am looking for metrics on the sizing of ISE servers which will initially carry the 3 roles Adm, MnT and PSN, for functions only Tacacs + (especially) and Radius (occasionally) for administration of 3600 devices.
On this link : https://community.cisco.com/t5/security-documents/ise-tacacs-deployment-amp-sizing-guidance/ta-p/3612253, I only saw information in terms of TPS on dedicated servers.
Do you have more detailed metrics?
In addition, the solution must then evolve to support a greater number of devices (15,000 to 25,000), and possibly towards NAC functions.
I will propose to evolve from a simple design to a distributed design with dedicated PSNs either to NAC or Tacacs +, by remobilizing the ISE servers from the initial target.
WHAT do you think of this approach?
Same as before, which metrics to use for servers?
Thank you in advance for your insight.
Regards
Serge
