Office Communications Server 2007 R2 offers three general topologies:

  • Office Communications Server Enterprise Edition in a consolidated configuration.

    This topology is recommended for most organizations of any size. It provides performance, high availability, and scalability. For details, see Enterprise Edition Consolidated Topology.

  • Office Communications Server Standard Edition.

    This topology is for small or midsize deployments, such as branch and pilot deployments, that do not have high availability and performance requirements. For details, see Standard Edition Topology.

  • Office Communications Server Enterprise Edition in an expanded configuration.

    The Enterprise Edition in an expanded configuration continues to be supported in Office Communications Server 2007 R2. However, the recommended configuration in Office Communications Server 2007 R2 is the consolidated configuration. The primary advantage offered by the expanded configuration in Office Communications Server 2007 was its ability to scale in very large deployments. In Office Communications Server 2007 R2, the limitations for scaling have been removed from the consolidated configuration, making it the preferred solution both in terms of scaling and simplified administration. For details about the expanded configuration, see Enterprise Edition Expanded Topology.

The following figure is a reference topology that illustrates the server roles and components in a consolidated configuration. The topics that follow describe the various topologies, components, and configurations that are supported for the internal network and the perimeter network.
