I don't think they are mutually exclusive, but I'd rather start off with one machine. I would find it easiest if it were on something like CentOS6.5. When we have that running and reporting like we want it we can add a FreeBSD server. The idea is that these machines would be available for a long time, ideally quite a few years. We want to have them with a stable time series of performance data so that when something disturbs the performance it sticks out like a sore thumb. cheers andrew
