Configure SQL Server in Lync Server 2013
Topic Last Modified: 2015-01-22
For each database that you deploy, you can use a single SQL Server instance for all databases for your Lync Server 2013 deployment that can be collocated on a database server. For details about database collocation, see Supported server collocation in Lync Server 2013 in the Supportability documentation.
Additionally, each SQL Server instance must be installed and available prior to completing the steps in Topology Builder that set up the databases, or manually creating the databases with Windows PowerShell cmdlets. For details about SQL Server supportability, see Hardware setup for Lync Server 2013.
