I have a question regarding routing setup for Exchange 2010
I analyzed the current routing using Exchange Routing Viewer
We are currently running coexistence with Notes using CMT binary tree and Exchange 2010
We have two data centers (NY & California) and two regions regionA and regionB with their own just one Exchange 2010 server (CA/HB/MB) in each region
In NY data center there are 2 HB/CAS servers and 3 MBs servers
In California data center there are also 2 servers with two roles (HB/CAS) installed on each, and 3MB servers.
The connectivity is great between two data centers (1GB connection).
Currently ALL 10 servers (5 srvrs in CA and 5 srvs in NY) are in the same site with the total active directory cost set to 0. Also, each
Region A has one Exchange 2010 with all three roles installed.
RegionB is same as region A
What is the best way to configure routing? Also, how does load balancing works for Hub transport role. Currently cisco hardware load balancer is used for the CAS servers, but I don’t see from the Routing Group that DNS round robin is enabled for the HUB transport servers. How does the traffic is redistributed in my scenario if all servers are in the same site.
Can you be as detailed as possible and send me links to documentation regarding best way setting up servers in the similar scenarios.
