OCS Standard Edition

Office Communications Server Standard Edition is deployed with the Front End Server, Back-End Database, A/V Conferencing Server, Web Conferencing Server, and Web Components Server installed on a single physical computer.

Office Communications Server 2007 R2 also automatically installs the following on the same Standard Edition computer:
* Application Sharing Server
* Four new unified communications applications:

• Response Group Service
• Conferencing Attendant
• Conferencing Announcement Service
• Outside Voice Control

Archiving Server Component

Microsoft Office Communications Server 2007 R2 Archiving Server is an optional server role for both Office Communications Server Standard Edition and Office Communications Server Enterprise Edition. This component archives for compliance purposes the content of instant messaging (IM) sent in Office Communications Server.

Archiving Server consists of the Archiving service and a SQL Server database, which is called the Archiving database.

In Office Communications Server 2007 R2, Call Detail Record (CDR) information is no longer collected in the Archiving database. CDR information is now collected by the new Monitoring Server in the Monitoring database. For details about supported configurations for Monitoring Server, see Monitoring Server Component.

If you deploy Archiving Server, you can choose one of the following configurations:

* Collocate the Archiving service with the Archiving database on a single computer.
* Install the Archiving service and the Archiving database on separate computers.
* In an Enterprise Edition expanded configuration, connect different Archiving Servers to different Front End Servers to eliminate a single point of failure.
* Collocate the Archiving service with a Standard Edition server

Monitoring Server Component

Microsoft Office Communications Server 2007 R2 Monitoring Server is an optional server role for both Office Communications Server Standard Edition and Office Communications Server Enterprise Edition. This component collects two types of data:

* Quality of Experience (QoE) data: numerical data that indicates the quality of your network media, and information about participants, device names, drivers, IP addresses, and endpoint types involved in calls and sessions.
* Call Detail Records (CDR): usage information related to Voice over IP (VoIP) calls, instant messaging (IM) messages, audio/video (A/V) conversations, meetings, file transfers, application sharing, remote assistance, and file transfers. CDR data does not include the content of IM messages.

Monitoring Server consists of the CDR and QoE services and their associated databases, which are always installed together in a single SQL Server instance and are known collectively as the Monitoring database.

If you deploy Monitoring Server, you can choose one of the following configurations.

For Standard Edition

* Collocate the Monitoring service with the Monitoring database on a computer that is separate from the computer running Standard Edition.
* Collocate the Monitoring service with the Monitoring database on the computer running Standard Edition.

Note:
This configuration is appropriate for very small deployments only.
If the Monitoring database is collocated with a Standard Edition server, you still need to install a full edition of SQL Server on the server. For details about supported versions, see Internal Office Communications Server Component Requirements.
