My personal opinion has been that we have seen great success in large environments with FreeRadius and using radrelay for mysql synchronization then an OpenLDAP-backend. We used FreeBSD/CARP and/or FreeVRRPd for failover but this can be accomplished in other methods.
FreeRadius has a built-in CLUSTERIP module which allows clustering/load-balancing/failover or you could AnyCast the systems for redundancy. As for load balancing other Radius servers which may not have it built in - I would say a hardware solution is usually great because you get support, etc. However, if you don't need the support then there are a ton of options available. You could go as far as load balancing it with LVS (which I personally do not like but MANY do :)) or software load balancers like pen/pound/haproxy.

Which loadbalancer is good to use? LVS or hardware one? or radius as a proxy? How database must be placed? How radius servers talk to DB? And which radius server you suggest? Radiator?
