Hi All,
We have a 3 physical box exchange setup with all Client Access\ Mailbox\ Hub Transport Roles on all 3.
We have a DAG comprised of all 3
I wanted to Create a CAS Array but have since learned that a CAS array on boxes contained in a DAG is not possible as the Network Load Balancing cannot be installed to create the cluster.
We have TMG implemented however apparently that cannot be used to do the load balancing for CAS Arrays?
So i then thought, I will then just create 2 new virtual machines and place them on our vSphere infrastructure as dedicated CAS machines in order to create the CAS, and use the Windows Network Load Balancing.
However, looking at the guides online it states that i need a dedicated NICS assigned to these VM's? Is this the case or is it just best practice for large setups?
We have about 700 mailboxes.
