Exchange 2010 ARR
Posted on 2014-03-05
Setting up a new Exchange 2010 environment with Server 2008R2 ARR IIS server for my front end OWA access. Question is should I setup load balancing on my ARR server, or Windows NLB my Client Access Array and point my ARR server to the cluster?
I have tested both solutions and both seem to work, though I am not testing under a heavy load.
Setting up the load balance on ARR requires client affinity, while using NLB on the CA cluster automatically by design will connect the client with only one node. (I believe)
