With Office Communications Server Enterprise Edition in the consolidated configuration, one or more Enterprise Edition servers are deployed, each running the Front End Server, A/V Conferencing Server, Web Conferencing Server, and Web Components Server. Office Communications Server 2007 R2 also automatically installs the following with the Front End Server:

• Application Sharing Server
  
  
• Application Server
  
  
• Four new unified communications applications:
  
  
  • Response Group Service
    
    
  • Conferencing Attendant
    
    
  • Conferencing Announcement Service
    
    
  • Outside Voice Control
    
    

Enterprise Edition in the consolidated configuration is the recommended topology for most organizations. This topology provides simplified administration, as well as performance and high availability. It can be scaled by adding servers to the pool.

Eight Front End Servers running the recommended hardware can support 100,000 active, concurrent users per pool. For details about hardware requirements, see Internal Office Communications Server Component Requirements.

The following considerations apply to the Enterprise Edition consolidated configuration:

• A single Enterprise Edition server can be configured as an Enterprise pool.
  
  
• A hardware load balancer is required when two or more Enterprise Edition servers make up a pool.
  
  
• The Back-End Database must be deployed on a separate computer.
