Roles of physical hardware on Exchange 2007 server

Question

On the same physical hardware can the Exchange 2007 server roles be deployed and configured?

Answer 1

Since Exchange 2007 is role-based, you can install all Exchange Server 2007 server roles, apart from the Edge Transport server role on a one physical server. When you are clustering, you can’t install the Mailbox server role on same server as the Client Access, Hub Transport, Edge, or Unified Messaging Transport server roles. When the server roles are installed on same or shared hardware, they function as the separate entities.
