SQL 2008 R2 Now Supported for Lync Server 2010

Today Microsoft announced that Lync Server 2010 officially supports using SQL Server 2008 R2 for a back-end pool database.

Previously only SQL 2008 SP1 or 2005 SP3 were officially supported (as I recently blogged about in The Lync Server Databases blog entry).

Many had used SQL 2008 R2 in labs with no issues. Microsoft needed time to put SQL 2008 R2 through it’s paces (testing) with Lync and found no issues.

You can read more about it here on NextHop: http://blogs.technet.com/b/nexthop/archive/2011/04/20/lync-server-2010-support-for-sql-2008-r2.aspx.

June 7th, 2012 Update: Microsoft SQL 2012 is NOT supported for all Microsoft Lync 2010 roles yet. The Microsoft KB article “SQL Server 2012 is not supported in some Lync Server 2010 server roles” details which Lync 2010 server roles are not supported.

While investigating a recent Lync issue, I had to reacquaint myself with the main databases used in a Lync deployment. In this blog post, I have documented my experiences for the benefit of others.

The Types and Uses of Databases in Lync

Microsoft Lync Server 2010 makes extensive use of Microsoft SQL. The two flavors of the core Front-End Lync Server role requires SQL:
