Microsoft Lync Server 2010 Standard Edition servers are intended for smaller organizations and remote locations from the main organization deployment. A Standard Edition server is designed for a user count of approximately 5000 homed users. The main difference between Microsoft Lync Server 2010, Enterprise Edition and Microsoft Lync Server 2010, Standard Edition is Standard Edition does not support the high availability features of Enterprise Edition. Specifically, you cannot pool Standard Edition servers like you can Front End Servers in Enterprise Edition. Also, the SQL Server database that Standard Edition uses is a collocated SQL Server Express version of SQL Server that is right sized for the workloads of a Standard Edition server. This is not to say that all roles must reside on a Standard Edition server. You can have stand-alone Mediation Servers, Edge Servers, Archiving Servers, and Monitoring Servers. The SQL Server database for the Central Management store and for the purposes of Lync Server 2010 must reside on the Standard Edition collocated SQL Server-based server. The A/V Conferencing Server must also remain collocated with the Standard Edition server. The Monitoring Server and Archiving Server use a stand-alone server with the SQL Server database.
