The number of servers each broker can start.

Use Maximum Servers Per Broker (-Mpb) to specify the maximum number of servers that multiple brokers can start to serve remote users for any one protocol.

The Maximum Servers Per Broker (-Mpb) parameter may be modified while your database is online using PROMON or through the _DbParams VST. This change will only take effect on the primary broker and its servers. Online changes to existing secondary brokers will require a restart.
