Creating a CAS Array on 2 Exchange Servers with DAG
Posted on 2011-09-09
I've been looking around at articles as there are plenty about but I have also read about some conflicting information about NLB, Vmware, and Clustering.
As this is a Live system I thought I'd best check!
Exch1 - All roles. Active copy of MBDB01
Exch2 - All roles. Passive copy of MBD01 + empty MDB02 (not used for now)
Both on VMWare with 1 Production NIC and one Replication NIC
Both configured in a DAG.
DNS: remote, autodiscover pointing to Exch1
How should I proceed in creating a CAS array?
End result I would like to achieve:
1. Load balancing between the 2 servers - not important but if it can be achieved without Hardware LB, great.
2. Automatic failover for ALL services (Mailbox and Client Access) should one server go down
3. Failback? Or is this manual?
