Hubs are required to support Reflection Gateway Jobs. If you plan on configuring Jobs, you must add one or more Hubs to this list.
The Reflection Hub service makes connections to SFTP servers and executes the Job actions you have define from the . page
You can add multiple Hubs to ensure availability of the Reflection Hub service. If you configure connections to more than one Hub, Reflection Gateway uses a round robin load balancing system to determine which Hub to connect to.
