Good article! An important side note - you must use Windows 2008 ENTERPRISE to utilize DAG.

True, and there are more sidenotes to DAG, like the fact that Public Folders can not take advantages of DAG, you still need to use Public Folder replication mechanism! But a pubic folder database can be homed on a server, who is a member of a DAG :-)

And what about Personal Archive databases in SP1? Five databases is the limit for the sum of active, passive, public folder and personal archive databases?

So, if i got it right, there is a limit of 5 databases per server. Does that mean that if you had tried to add the copy to the other server (the one with only 2 databases) would it have been successful?

NOPE !!! FAIL!!!
5 Databases PER Server !!!
look here: technet.microsoft.com/.../bb232170.aspx
In Your Scenario you already have 5 Databases on E2010CHM1 !!!

It looks like the 'Soleil' db is already part of a DAG(?)
Also, if you had attempted to add 'Employees' to your DAG would it have worked (since server 2 has less than 5 databases)?

I have a question that is related - 2 Std edition with 5 databases each - 2 Active - 2 passive and 1 PF each (5 DB per server) what about adding a 3rd Enterprise server and creating a 3rd copy of each database on the enterprise. I am virtually sure this is fine as the Ent server is not attempting to copy anything back to either std servers.

Hi guys:
I got a question about licensing Exchange into a specific scenario.
Here´s my story:
My company has 4 mailbox servers running on EXchange 2010 Enterprise.
We are moving to DAG configuration, from microsoft website we know that Enterprise version can support up to 100 databases (Active, passive and public folder).
Since we have 4 instances running with Exchange 2010 Enterprise, and as we know this version support up to 100 databases , does that mean that my environment could have 400 databases as maximum?
