Exhchange Hub transport fialover
Hi All,
As you may have seen by previous posts we are working to provide an HA exchange solution. We have decided that the best way seems to be with the cloud solution mimecast. However they have a 3rd party system that requires a hub transport to work. We therefore need a fail-over hub transport onsite to ensure continuity in the even of hardware failure.
Can anybody advise on the steps needed to set-up a hub transport fail over?
Thanks.

Hi Will,
What is the process involved for getting that setup?

There's no specific process, you install one Hub Transport role on 1 server, you install another Hub Transport Role on another Exchange server. Each server will automatically detect each and will work hand in hand, without any additional configuration.
Yes that is correct, Hub transprot roles require 2 or more in order to be HA. (this is per SITE). So if you have multiple sites that host exchange (probably not due to using mimecast) but if you do, then you will need to add an additional Hub-T role in your second site.

So we have full exchange 2010 in-house at the moment.
If we just install another server with full exchange will it work off the bat or is there configuring to do with CAS to be done?

For the Hub Transport, no configuration extra.
For Load Balancing the CAS servers, with All roles installed on each server
Without a DAG.. you can set up a Windows NLB for the CAS Array.
With a DAG..you must use a load balancer such as an additional appliance or hardware load balancer and set up a cas array.
Here's some details on how to set up the CAS Array: http://blogs.technet.com/b/ucedsg/archive/2009/12/06/how-to-setup-an-exchange-2010-cas-array-to-load-balance-mapi.aspx
