Display server deployments with multiple data servers
The display server maintains connections with the data servers named in attachments and commands of its client dashboards.
Illustration of display server with multiple data servers
Important: 
In a display server deployment, each named data server must be started with the --namedServerMode option.
The logical data server names specified in the Builder's Application Options dialog are recorded in the file OPTIONS.ini, which is used by the Deployment Wizard to define deployment logical names. You can override these logical name definitions with the --namedServer name:host:port option to the display server executable. Below is an example. This is a sequence of command-line options which should appear on a single line as part of the command to start the executable:
--namedServer Server1:ProductionHost_A:3278 --namedServer Server2:ProductionHost_B:4278 --namedServer Server3:ProductionHost_C:5278
Here Server1, Server2 and Server3 are the server logical names.
