UMH/UMA : Deployment Roles

Deployment Roles
The role that you assign to your Dell SonicWALL GMS instance defines the Dell SonicWALL Universal Management Suite services that it will provide. Dell SonicWALL GMS uses these services to perform management, monitoring, and reporting tasks.
Your Dell SonicWALL GMS instance can be deployed in any of the following roles:
In the UMH or UMA system management interface, clicking Details in the same row as a role provides a list of the services that run on a system in that role, and information about using the role.
As the number of managed appliances increases, a more distributed deployment provides better performance. To manage large numbers of SonicWALL appliances, you can use several SonicWALL GMS appliances operating in different roles in a distributed deployment. You can also use Windows Server machines running SonicWALL GMS in any of the roles.
The All-In-One or Database Only roles automatically include the MySQL database.
You can add multiple consoles to your GMS Deployment and that in such a deployment, all consoles except one should be marked as redundant consoles, and that the Include Redundancy check box can be used for configuring a GMS console as a redundant console.
You can scale your deployment to handle more units and more reporting by adding more systems in the Agent role. Agents provide built-in redundancy capability, meaning that if an Agent goes down, other Agents can perform the configuration tasks and other tasks of the Agent that went down.
When first deploying GMS, if you are going to use a Microsoft SQL Server as the GMS database, then make sure you install the SQL Server database first and then use the IP and credentials of the SQL Server for role configuration of all GMS appliances and servers. If using MySQL, first install a GMS appliance/server that has MySQL database included with it.
You can install a GMS appliance/server that has a MySQL database included in one of the following ways:
By selecting Include Database (MYSQL) if configuring the appliance with any other role
You can configure the role of the UMA EM5000 appliance without using the Role Configuration Tool.
All role configuration is performed in the appliance management interface, available at the URL: http://<IP address>:<port>/appliance/
