System Requirements for SQL Server
Topic Last Modified: 2012-09-13
Before you deploy Enterprise Edition server, install Microsoft SQL Server 2008 R2 or Microsoft SQL Server 2012 on a dedicated computer that meets the hardware requirements. For details about hardware requirements, see Server Hardware Platforms in the Supportability documentation. For details about software requirements, see Database Software Support in the Supportability documentation.
Before you create the Front End pool, you must also configure Windows Firewall to allow Lync Server 2013 access to SQL Server over specific ports by defining ports for the server using SQL Server Configuration Manager and opening ports in Windows Firewall with Advanced Security.
