    Two member DAG scenario.

    You can have more members but consider performance and scaling when doing this as it will obviously put more load on the servers with more roles.

  • Just to follow up on Chris's comment.  If you have multiple roles on each server and configure them in a DAG, then you will not be able to use Network Load Balancing for the CAS role.  If you want to load balance the CAS role you will have to use a Hardware Load Balancer.
