How to setup an exchange 2010 hub/cas array on single site
Hi all,
I have an exchange 2010 test environment that will have the following:
Site 1
2x edge servers
2x hub/cas servers
2x mail servers
Site 2
2x edge servers
1x cas/hub/mail server
all setup in vm at both sites.
So the plan would be:
To achieve this please could you point me in the right direciton with how to/setup guides/links on how I can setup the hub/cas servers so if one fails the other one automatically kicks in.
I know I subscribe the edge servers to the site that the hub/cas servers are on, i also guess I should be creating a DAG group between the 2 servers on the same site, so would i also create a dag between a mail server and another mail server that is on a different site for failover?
Thanks and hope that was understandable to a point!

So the plan would be:
site 1 where all clients connect for mail.
site 2 edge servers sync to site 1 cas/'hub servers (this will allow 2 ways for e-mail to be received if an internet connection goes down)
site 2 mail server has a copy of databases on site 1 for off site replication
if site 1 was completely lost, the cas/hub/mail server at site 2 can kick in?

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You should have more than one hub transport server so tha if one hub server goes down mail will go through the other hub transport server. Make sure you have at least two hub transport servers in case one fails.
for the client access servers I would create client access server array in each active directory site so that you don't have a single point of failure. when you setup a client acces server array in each site multiple client access servers will be part of this array. You still need to utilize a load balancing solution for the array such network load balancing or Hardware load balancing.
NOTE: You cannot shared a load-balanced array of cas servers between sites. You will have to create a cas array in each site.
