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.
