My Exchange boxes are DL380 G4's with dual cpu with a lot of disk space left.
Wondering how many exchange mailboxes these servers will support before I
need to add new Exchange servers. I currently have about 2000 users on each
server and my exchange data base runs about 8 - 9 gb on each server. These
servers also act as the DC/GC's for the Unity standalone AD domain. I am
having no issues but need to plan for the future. I expect to be upgrading to
Unity 7 next year.<o:p></o:p></span></p>
