How do I calculate computing power needed per user?
For instance, a small office with five email power users who want Win2k3 SBS can use a less powerful server than a company with 30 employees you just you regular email. (I am of course referring to exchange).
Then add in the company database, file server, etc....
How do I compute what speed CPU, and how many CPUs are appropriate for the business? How do I computer how much RAM to stick in there?
