5 node DAG and majority

[Jude Perera]

Hi team,

In am Exchange Server 2010 5 node DAG architecture where a FSW is also configured in the DAG config. settings the servers are placed as below;

3 - Head Office

2 - DR Site

Lets say if the DR is completely down due to maintenance. In such a situation what will happen if 1 of my HO server goes down?

Will the DAG fail?

Thank you.

Regards,

Jude.

You have an odd number of nodes, so FSW isn't used. In this setup, 3 nodes should remain up to keep quorum (and DAG up). When DR is down or unavailable, you can't tolerate server failure in primary DC.
