How many Data Server processes are recommended on nodes that do not run file store processes?

The recommendation of having 2 Data Server processes on nodes that do not run file store processes is based on the need for redundancy and load balancing within Tableau Server architecture. By having two Data Server processes, the system can handle requests more efficiently and provide failover capabilities. This ensures that if one process encounters an issue or becomes overloaded, the other can manage the traffic, thus maintaining a smoother performance and availability for users accessing data sources.

The balance of resource allocation also plays a critical role in supporting multiple simultaneous connections. Having two processes allows the system to effectively distribute workloads, providing a more resilient and responsive environment, especially when dealing with higher data demands or concurrent user queries.

Nodes that do run file store processes typically have their own set of requirements and responsibilities, which is why the recommendation is aimed specifically at nodes not handling file storage. The configuration is optimized for performance and reliability, making it a best practice for Data Server management in Tableau Server environments.
