Distributed computing system configuration

A single-geo system includes a network configuration generator and a first computing system rack, or a multi-geo system includes a network configuration generator, a first computing system rack, and a second computing system rack are described. The system receives network information for a first plurality of nodes and a second plurality of nodes, and generates a system-wide network configuration file including network configuration information for the first plurality of nodes and the second plurality of nodes. Each plurality of nodes includes a controller node to receive the system-wide network configuration file, identify network configuration information for this plurality of nodes in the system-wide network configuration file as being part of the computing system rack, and update network configuration for this plurality of nodes based on the identified network configuration information for the computing system rack.
