For example if I were to suggest box with dual 8 core E5 CPUs, hardware PERC RAID card with 1GB cache, 48TB of 7.2k SATA in RAID6 and 32GB (or more) of RAM running as a SD
I actually use a Raspberry Pi with attached USB disks as an SD. I have about a dozen clients (including some VMs) and it works fine. Where you need the horsepower is for the database, so in my case, the Pi only runs the SD (and an FD for backing itself up), and the director and database run on a different machine with much more memory and CPU power.
