Microsoft Office Communications Server 2007 R2 Group Chat Server is an optional server role for both Office Communications Server Standard Edition and Office Communications Server Enterprise Edition. Group Chat Server supports persistent chat sessions. Unlike group instant messaging (IM), an Office Communications Server group chat session persists, along with all messages, files, Web links, and other data that was part of the ongoing conversation.
Group Chat Server consists of the following components:
- Chat Server, which runs three server roles: Lookup Server,
Channel Server, and Web Services
- Group Chat database
- Compliance Server for archiving group chat activity, if
required to meet compliance regulations
- Compliance database
Group Chat Server has the following requirements:
- Before you deploy Group Chat Server, you must deploy Office
Communications Server 2007 R2.
- Each Chat Server, as well as the Compliance Server, requires a
certificate issued by the same certification authority (CA) as the
one used by Office Communications Server 2007 R2.
- The only database collation supported for Group Chat is
- For details about additional requirements and requirements
related to compliance, see
the Planning and Architecture documentation.
In a Group Chat topology, the following considerations apply:
- Chat Server and the group chat database must be installed on
- Compliance Server, if deployed, must be installed on a separate
computer from Chat Server.
- The Group Chat database and the Compliance database can be a
shared database for small deployments.
- Group Chat can be scaled by adding up to two additional Group
Chat Servers (for a total of three servers).
