Using DAG Internal Cluster IP Address to Point CAS / MX Records - Exchange 2010

In a 2 Exchange Server 2010 environment running a DAG I'm about to point a CAS array to the internal cluster IP address of the DAG.  Any thing I'm missing?  I'm assuming if one server fails in the DAG the client access won't be effected?

Also, I'm taking the email MX record on the DNS server and pointing it to the DAG as well - I'm assuming it would fail over SMTP connectors as well this way?

If I'm missing anything let me know - Both servers are on the same site with only 50 clients using 2010 Outlook and/or Outlook anywhere.

I beleive we already went over this together, pointing your cas array to the dag ip will provide you high availabilty but not load balancin which seems to be ok in your case

You dont need an mx record internally

as they are in the site ,,, Clients will still use the same cas array > but they will be pointed to diffrent database after the primary database fails.

As its a DAG you will not be required to do any manual changes .

See u need a cas array, the RPCClientAccessServer Attribute of the database must be made to point to the Cas Array

I am confused why are u mixing IP of DAG and CAS array when both are diffrent entities or can i say i dont fully understand what do you mean by  " pointing your cas array to the dag ip "

You need onlyy one MX record which points to your cas array for external access

If the author doesn't respond then the question falls to cleanup.

The cleanup volunteers are normally experienced in the subject they are cleaning.  Exchange is one of my zones.  The job of the cleanup volunteer is to identify if a technically correct answer has been proxides and if not mark the question for deletion.

On this particular question, I felt Akhater prvoided a technically correct option, I therefore opted to select it as the solution.
