Hi there again,
About this solution can anybody help about the best partition layout for
these machines?
For such a OSS system we need these 4 machine and having best partition
layout for them is important for example maybe we need a big /var/log for
Radius Server and etc.

   1. Load Balancer (ipvs)
   2. Radius Server (radiator/freeradius)
   3. Database Server (mysqld)
   4. Web Server for Billing (apache2)

Thanks
