Cluster Management and Lead Host Designations

There are two main configuration settings that determine how the cluster functions with respect to cluster management:

leadHostManagement : This cluster-level setting determines what will perform the cluster management role. When true, lead hosts perform the cluster management role. If you have chosen to store your cluster configuration settings in a shared network folder, true is the only valid value for this setting. False indicates that SQL Server will perform the cluster management role. If you have chosen to store your cluster configuration settings in SQL Server, this setting will default to false. When using SQL Server to store cluster configuration settings, you can set this setting to true and let lead hosts perform the cluster management role.

quorumHost : This cache host-level setting determines which cache hosts will be lead hosts when lead hosts perform the cluster management role. Even if SQL Server is going to perform the cluster management role, the installation program designates lead hosts, in case you later change the LeadHostManagement setting.

For more information about changing these settings, see How to: Set the Cluster Management Role and Lead Host Designations (Velocity).

Note 
The "quorum" reference is a term that was used in a previous community technology preview (CTP) of "Velocity" to refer to a lead host. The name of this setting may change in the future.
