Hi All,
I have some questions about a 3 node Dag. Two of the nodes are going to be in the same site (server A and B) and the other in another Physical/AD site (server C)
All servers are going to be running all three Exchange roles. Server A will be Phyiscal using lcoal storage and Servers B and C will be Virtual on shared storage. Servers A and B will be sitting behind a netscaler for load balancing of the CAS role.
My question is if i can have server's A and B in an Active Active DAG (dont even know if this is possible) so i can have local site redundancy and load balancing for the mail box role. then the server C will be a passive DAG node.
Also, for redundancy of incoming mail, can i just set up two MX records pointing to the netscaler and the other to Server C (mx for Server C would have a different prioirty value)
Is this a valid high level design. am i missing anything out.
Thanks
