The question of SQL AlwaysOn support is coming up again and again from SQL administrators on Lync deployments and workshops at the moment.
Sadly at the moment (March 2014) SQL AlwaysOn is not supported for providing high availability for Lync Databases. Only using SQL Mirroring and server clustering is supported.
But there is some good new….
At Lync Conference 2014, it was announced during ‘What’s new in Lync Server/Service’ (SERV203) session by Ali Rohani and Brandon Bernier that support for AlwaysOn Availability Group for Lync Server 2013 back-end server high availability is coming in Q3 CY2014
Here is slide 17 from the session
SQL Administrators rejoice!
