After reading many different methods of setting up DAGs I finally got round to installing a system.
I am only looking for opinions on my set up below to see if I could do anything differently.
The aim is to provide mailbox availability in case of a long term (more than a few hours) site/server failure.
I have 3 geographically dispersed sites(UK, IE,DE) all connected via VPN
My original setup has each site hosting its own local mailbox/cas server.
In each site I added an additional mailbox server for the DAG. I cannot add multiple servers in each site and as each server can only be in one DAG, I have created a DAG group as follows:
DAG Name: DAG Group
Member Servers: MBX-IE, MBX-DE, MBX-UK
Witness Server is a file server in the IE site
MBX-IE - Hosts active copy of database for lcoal users, plus a copy of MBX-DE and MBX-UK
MBX-DE - Hosts active copy of database for lcoal users, plus a copy of MBX-IE and MBX-UK
MBX-UK - Hosts active copy of database for lcoal users, plus a copy of MBX-DE and MBX-IE
I have replication working ok, but I have disabled automatic failover, as I don't want databases switching over when there is only a WAN failure.
I have tested the manual failover by:
take MBX-IE offline
on MBX-DE which is 2nd in the activation preference, manually activate Database Copy
This seems to work ok, and users can get their messages from MBX-DE.
After bringing MBX-IE back online again, I can switch the database back again.
