Servers running Microsoft Lync Server 2010, Enterprise Edition are intended for large organizations as the main organizational deployment. Enterprise Edition server is designed to scale to approximately 80,000 homed users per pool. The main difference between Enterprise Edition and Standard Edition is Standard Edition does not support the high availability features of Enterprise Edition. For high availability, multiple Front End Servers are deployed to a pool, the SQL Server-based server can be clustered, and the SQL Server database is deployed as a dedicated SQL Server-based server and maintains instances of data for the Front End pools. With Enterprise Edition server you can choose to collocate or define stand-alone servers for A/V Conferencing Server and Mediation Server. The Monitoring Server and Archiving Server can use a stand-alone SQL Server-based database server, or can have instances created on the SQL Server-based server for the Front End Servers and pools.
