Use the options on the Servers tab to do the following:
Adjust the number of processes running on Tableau Server,
Configure a distributed Tableau Server environment, and
Select the preferred active repository for failover situations.
You can also use the Server tab to add computers on which to run Tableau Server processes.
Number of processes per server
Tableau Server deployments run multiple processes. You can choose to run the processes one computer, or to distribute them across multiple computers. To improve performance, you can adjust the number of processes that run on each computer, for each process type.
For more information on changing the number of server processes for a single-server environment, see Reconfigure Processes.
For more information on how many processes to run in order to improve performance, see Performance Tuning Examples.
For more information on setting up a multi-server, or distributed, environment, see Distributed Environments.
Preferred active repository
When you configure Tableau Server after the initial installation, you have the option to specify a Preferred Active Repository. This is an optional step, and if you do not specify a preferred active repository, Tableau Server will select the active repository on startup.
Configure a preferred active repository if you want Tableau Server to select a specific node on startup. You might want to do this if you have a particular server you want to use for your active repository (a computer with more disk space or memory for example), or if you are using custom administrative views. Custom administrative views have embedded connection information that refers to the repository for which you created the views.
