Exchange 2007 UM role shared with CAS, HT or MB? Which is best?
Posted on 2008-10-28
I have an Exchange 2007 environment with 2 load balanced CAS servers (using NLB), 2 HT servers and for now, 2 MB servers. I want to introduce UM into the environment without adding more hardware. Which, if any specific, role is best to share and add UM on in this scenario? All of the hardware is very capable of handling the load. I wasn't sure if there are pros and cons of sharing certain roles on the same hardware of if NLB is helpful or harmful in this case.
