IT Administrators like to consolidate as many server roles & applications as they can on a single server, while maintaining reliability and compatibility. Of course, Office Communications Server 2007 has many components (Edge Server, Media Server, Director, Front-End Server, Web Conferencing Server, etc.), some of which must be installed on separate servers and cannot be collocated on the same computer. Consolidating as many server roles as possible not only reduces hardware costs, but makes administration and maintenance easier as well, thus lowering TCO. Microsoft has released a useful chart identifying which components that explicitly cannot be collocated and those that can. Any combination that is not identified has not been tested and is not supported.Via Microsoft:
The following table identifies the Office Communications Server roles that can and cannot be collocated. In addition to the server roles identified in the table, the following collocation scenarios are explicitly not supported for Office Communications Server 2007 R2:
- Any server role on an Active Directory domain controller
- Exchange UM and Office Communications Server
