About high availability support for SharePoint Server
The high availability (HA) solution for SharePoint Server is a combination of monitoring and recovery support for SharePoint applications and high availability support for SQL Server databases used by SharePoint Server.
The SharePoint high availability configuration components are as follows:
VCS provides an agent for SharePoint that performs the task of managing the SharePoint Web Applications, Service Applications, and services configured in the server farm. Depending on the configuration, the agent monitors, starts, and stops the SharePoint components in the cluster.
SharePoint Web Applications are configured in a VCS parallel service group. A parallel service group runs simultaneously on multiple nodes in a cluster. The parallel service group manages the Web Applications configured in the farm. The state of the parallel service group represents the state of the Web Applications configured in the farm. If a Web Application becomes unavailable, the agent attempts to restart the application in the farm.
SharePoint Service Applications and services are configured in a separate service group that is created locally on each cluster node. The service group manages the components configured on the local node only. If any of the components become unavailable, the agent attempts to restart the component on the local node.
The VCS agents for SQL Server database agents are used to configure high availability for the SharePoint databases. The agents monitor the health of the SharePoint databases as well as underlying resources and hardware. If a failure occurs, predefined actions bring up SQL Server on another node in the cluster.
