Freeradius Clustering

[Fred Zinsli]

Hello everyone

Sorry if this has been covered, but I have googled without finding.

I am looking to replace our current servers and am looking to 
reconfigure the network.

I am wanting to know if Freeradius can be clustered? and if so can 
someone point me to some documentation on the subject.

I am also wanting to know how the calculate the new specs for the new 
servers.

Many thanks in advance.

Regards

Fred
