Site database server

The site database role is automatically installed during the deployment of each ConfigMgr server type, as each saves data in the database. This role cannot be uninstalled.

Administrators managing environments with more than one ConfigMgr server might change the configuration of this role, for instance, by enabling the compression of data synchronized between SQL Servers:

The administrator can also change the port used by the SQL service broker for connection between SQL Servers. There is also a possibility of moving ConfigMgr SQL database to another machine after the server is installed.
