The Office Communication Server 2007 Planning Guide provides loose guidelines on infrastructure sizing. These are only guidelines and not hard limits, except that an Enterprise Pool will only support up to 125,000 users.

Topology Recommendations:

Topology

Servers Required

Maximum Users Supported

Standard Edition 1 – Standard Edition server
1 – (Optional) Archiving Server collocated
5,000
Enterprise pool:
Consolidated Configuration
4 – Enterprise Edition Front-End servers running all server roles
1 – Backend
(Optional) 1 Archiving Server
30,000
Enterprise pool:
Expanded configuration
With Mid-Range SQL Backend
4 – Front-End Servers
2 – Web Conferencing Servers
2 – A/V Conferencing Servers
2 – IIS Servers
1 – Backend SQL Server
(Optional) 1 Archiving Server
50,000
Enterprise pool:
Expanded configuration
With High Performance SQL Backend
8 – Front-End Servers
4 – Web Conferencing Servers
4 – A/V Conferencing Servers
2 – IIS Servers
1 – Backend SQL Server
(Optional)2 Archiving Servers
125,000

Edge Server Topology Recommendations:

Topology Supported Performance
Stand-alone Access Edge Server 15,000 client connections
Stand-alone Web Conferencing Edge Server 3,000 client connections
Stand-alone A/V Edge Server 1,500 concurrent audio/video sessions
Collocated Access Edge & Web Conferencing Edge Server Access Edge Server: 5,000 client connections

Web Conferencing Edge Server: 1,500 client connections
Collocated Access Edge, Web Conferencing Edge & A/V Edge Servers (Consolidated Edge Topology) Access Edge Server: 5,000 client connections

Web Conferencing Edge Server: 1,000 client connections

A/V Edge Server 500 concurrent audio/video sessions

Note A/V experience may be degraded if sessions approach the maximum limit. We recommend that you deploy a separate A/V Edge Server for the optimal A/V experience
