Hello Ramesh,

Capacity depends a lot on how the RADIUS server is accessing authentication stores. Are you storing these users in a LDAP or a DB? It is these resources that generally become the bottle-neck first rather than the RADIUS Server.

Also, are you doing authentication and accounting (RAS) or just authentication (EAP)?

Please suggest interms of load balancing and capacity per server.? How many radius servers will be ideal to keep.
