Configuring DAG Mailboxes Exchange 2010 with a Remote Site for Disaster Recovery
Posted on 2014-12-03
I am planning an Exchange 2010 DAG setup for Mailbox Databases with a Disaster Recovery ability.
We have 2 locations that are connected via a 100Mb Fibre VLAN provided by our ISP.
Site 1 Main Office all users, Site 2 Warehouse no local users
Plan is to have (2) Exchange 2010 servers in Site 1 both with CAS, HUB and Mailbox roles (EX1, EX2) and 1 Exchange 2010 server in Site 2 with CAS, HUB and Mailbox Roles (EX3).
EX 1 will have a Mailbox database with DAG to EX2 and 3rd priority to EX3.
EX 2 will have a Mailbox database with DAG to EX1 and 3rd priority to EX3.
Exchange 2010 CAS Array including EX1, EX2 and EX3.
Outlook will point to a Network Load balancer (kemp or Baracuda).
Any thoughts or suggestions on this configuration would be appreciated.
