– In vSphere 6.0, the vCenter Server Watchdog feature was introduced. vCenter Server Watchdog monitors and protects vCenter Server’s VPXD providing better availability by periodically checking the vCenter Server processes (PID Watchdog) or the vCenter Server API (API Watchdog).
– … third-party solutions are available to protect VMware vCenter Server 5.x and 6.0 … these solutions are not certified by VMware for use with vCenter Server to provide high availability … Microsoft SQL Server 2012/2014 AlwaysOn Availability Groups (AG), Microsoft SQL Server 2012/2014 AlwaysOn Failover Cluster Instance (FCI) & Microsoft SQL Server Database Mirroring
