Its a physical box dedicated to just solarwinds (I hijacked a old exchange mailbox server 
) I did remove the thwack web parts. The part that gets me is sometimes its really fast. Just the other day we were on it during a meeting and myself along with another admin couldn't believe how fast it was!
I will try to get some solid states ordered, since we spent so much on all the different sw parts, why not spend a few more thousand for new hardware.
