Server utilization and seperation. I need 10 web servers, none of which are going to be busy, but each organization in my business wants their "own". 10 vms on a 2 cpu box makes more sense that 1 web server on each of ten. Add a second vm host for some redundancy, etc, etc. On Fri, 27 May 2011, Digimer wrote: > On 05/27/2011 02:33 PM, James B.
