EV system mailboxes and archiving tasks for Exchange 2010 DAG

[ia01]

There are two DAGs straddling the two AD sites, and each consists of two member nodes:

DAG1 - Members MBX1  (SITE1) , MBX3 (SITE2). SITE1 active, SITE2 passive.

DAG2 - Members MBX2  (SITE1), MBX4 (SITE2). SITE2 active, SITE1 passive.

We have mailboxes distributed across 12 databases. Each DAG hosts 6 active and 6 passive databases.

How many EV system mailboxes and archiving tasks we need?

Many Thanks

You have to create the archving task for the all the exchange server in the DAG running the mailbox server role . you need to failover the DAg to the passive node to create archving task .

You dont need a sperate system mailbox for you passive node , as when you failover to passive node the system mailbox would also be moved to the passive node.
