UMH/UMA : Deployment Roles

Configuring the Database Only Role
The Database Only role is used in a multi-server SonicWALL GMS deployment. In this role, the server is configured to run only the database service. SonicWALL recommends that one of the servers in a multi-server GMS deployment is assigned a Database Only role.
Only the SonicWALL Universal Management Suite Database service runs on a Database Only system.
The MySQL database engine is pre-installed along with the SonicWALL GMS installation. SonicWALL GMS can also use a MySQL database or a Microsoft SQL Server database installed on a server. Only the MySQL database included in the installer is supported. On the Deployment > Role page in the SonicWALL GMS appliance management interface, you can configure your SonicWALL GMS systems to use either a MySQL or a SQL Server database.
To deploy your SonicWALL GMS in the Database Only role, perform the steps described in the Configuring Database Settings section, on page 730.
