ACS Performance & Scale

we are planning to deploy ACS with large deployment license on Virtual machine to support up to 30,000 NAD's If we size virtual machine as per cisco's 3415 specification will that suffice the requirement ?

Regards,

Hi Velpalani,

What version of ACS are you running? Just want to let you know that the last version of ACS is 5.8. BU is planning to announce EOL for 5.8 later this year(2016). Please see the EOL details here. 3595 is supported in 5.8.1. For ACS 5.8.1,150,000 network devices are supported in 35xx appliance. Here is the information from the release notes. Older appliance support upto 100,000 network devices.

That said, ISE will be the future platform for TACACS+ or for secure access. ISE is supported from ISE 2.0 onwards, the latest ISE 2.1 supports upto 100000 devices, ISE is easy to use, configuration can be easily deployed with Workcenters for creating workflows, centralized upgrade and a lot of serviceability options outlined here. Here is the latest ISE 2.1 release notes and for ISE scaling and performance
