The following list contains the database management systems for the back-end database, the Archiving database, and the Monitoring database that are supported by Microsoft Lync Server 2010:

  • Lync Server 2010 does not support SQL Server 2008 32-bit edition, SQL Server 2008 R2 32-bit edition, or SQL Server 2005 32-bit edition. You must use the 64-bit edition.

  • SQL Server Web edition and SQL Server Workgroup edition are not supported. You cannot use them with Lync Server 2010.

  • Lync Server 2010 does not support native database mirroring.

  • To use the Monitoring Server role, you should install SQL Server Reporting Services.

In a Front End pool, the back-end database can be a single SQL Server computer. Alternatively, two or more dedicated SQL Server computers can optionally be clustered in a multiple-node active/passive configuration. A SQL Server cluster for the back-end database improves availability by providing failover capabilities. In a multiple-node cluster, the Lync Server 2010 SQL instance must be able to failover to a passive node that, for performance reasons, should not be shared by any other SQL instance.

SQL Server database clustering using Windows clustering is the only SQL Server high availability mechanism supported by Lync Server 2010. SQL Server clustering support includes the following:
