As matter of interest, what hardware do you use? i.e. what CPU's, size
of RAM and RAID cards do you use on this size system?

Everyone always recommends to use smaller RAID arrays than one big fat
one. So, I'm interested to know what you use, and how effective it
works. i.e. if that 30TB was actively used by many hosts how does it
cope? Or is it just archival storage?
