Do you really mean that 30 active sessions eat 70% of 12 cpus, i.e 9
cpus? And how many concurrently active users would your dr box
support? My best guess it would be most of those 30 wouldn't it? If so
You'd be mad to choose anything other than an identically specced box.
If on the other hand you actually intended 300 concurrent users and
the dr box would only be supporting far fewer then you'd likely get
away with fewer cpus.
