Failover and load-balancing of connector requests is achieved by each provisioning server based on the CSF configuration defined using csfconfig or Connector Xpress.
Each provisioning server consults the CSF configuration that applies to it and determines which Connector Servers it should use to access each endpoint or endpoint type. Failover and load-balancing occur when there are multiple connectors servers configured to serve the same endpoint or endpoint type.
Failover and load-balancing are unified and cannot be controlled separately. One cannot indicate that a particular connector server is to remain idle except when needed for failover. Instead, a provisioning server that is configured to use two or more connector servers interchangeably will distribute work between these connector servers (load balancing) during normal operation. Should one or more of the Connector Server become unavailable, the remaining connector servers will provide failover support for the unavailable connector servers.
