Hi All

Tell me how many DAGs could be created in Exchange sever 2010, for example... DAG01,DAG02.....................limit?

Hi Kapil,

You can create as many DAGs as required. There's no hard limit to the number of DAGs you can have in an Exchange 2010 org.

Exchange 2010 Enterprise edition can have up to 100 databases. This includes active as well as passive database copies. So it's really this limitation that controls how many database copies you can have in a DAG plus the number of DAG members in the particular DAG. For instance, if you have a DAG that consists of two DAG members, you can have a total of 50 replicated databases (50 active and 50 passive on each DAG member). If you have three DAG members, you can have 33 and so on.

Thanks Sunny :)

Is there any Technet article regarding this confirmation.
