SharePoint 2013 HA on two boxes with SQL

 We have two hardware boxes to setup SPS 2013.

 Below is the config,

 Box1: SQL 2012 Sp1 Cu3 - Always On (Primary Replica - ConfigDB/ContentDB) (Failover clustering)

 SPS 2013 - Central Admin, front end

 Box2: SQL 2012 S1 Cu3  - Always On (Secondary Replica - ConfigDB/ContentDB) (Failover Clustering)

 SPS 2013 - Central Admin, front end

 NLB not used because failover clustering already used. load balancing is neither a requirement but failover is. We use SQL Always On listener IP address to connect to this farm.

 Is this a supported scenario as well ?
