Freeradius Hardware requirements

[nf-vale]

Hi all,


Please help me if you can. I need some data about Freeradius hardware
"requirements".

This is for a project I'm working on and I need to establish a minimum
hardware requirements for a radius server (Freeradius 2.0.5) that will
serve about 3000 users, and will be used as authentication and
authorization server for some wireless AP's and 802.1x switches.

It's expected that users will massively login (400 or more) at certain
time and after that re-authentication will happen every 6 or 10 mn, for
802.1x clients.


Also I have some doubts about were to store user info, sql DB (postgres
maybe) or LDAP. What would it be the better solution, in terms of
performance.

The OS is a debian alike (2.6.19 kernel).

Can anybody provide me some info on this?


Thanks in advance
