Greetings, we are looking at deploying ACS 4.2 in our estate to support AAA services, essentially all we want to achieve is the ability control access to a variety of Cisco network devices (Switches, Routers, Firewalls) as well as perform command accounting functions.
I appreciate that v5.2 is now avaliable but it appears too feature rich and expensive for our needs, however after checking the data sheets for 4.2 im unable to determine the maximum number of hosts 4.2 will support or whether it is possible to virtualize the Windows host that ACS will be installed on?
Any assistance would be greatly appreciated.
Regards

Hi Mark,
The following link gives the details of the max AAA clients and users that can be configured.
It says the following:
Maximum users supported by the ACS internal databaseāThere is no theoretical limit to the number of users the ACS internal database can support. We have successfully tested ACS with databases in excess of 100,000 users. The practical limit for a single ACS authenticating against all its databases, internal and external, is 300,000 to 500,000 users. This number increases significantly if the authentication load is spread across a number of replicated ACS instances.
Maximum number of AAA clients supportedā ACS has been tested to support AAA services for approximately 50,000 AAA client configurations. This limitation is primarily a limitation of the ACS memory.
You can install the ACS 4.2 on a windows machine and it works fine. it runs perfect on virtual machines as well.
Hope this helps.
Regards,
Anisha
