High availability for autonomous machine control system

A control system (10) for a work site (12) including an autonomous machine (16) includes a central control system (14) that includes a cluster of servers (46) configured to execute an autonomous control server application on exactly one (72) of the cluster of servers (46). A RAID system (56) is in communication with the cluster of servers (46). A first switch (42) interconnects a first network (38) with the cluster of servers (46), and a second switch (44) interconnects a second network (40) with the cluster of servers (46). A UPS system (60) interconnects a power source (62, 63) with the cluster of servers (46), the RAID system (56), and the first and second switches (42, 44). The machine control system (24) is communicatively coupled with the central control system (14) via a wireless network (74) and one of the first and second networks (38, 40). The machine control system (24) transmits machine position information to the autonomous control server application and receives a route plan (90) generated by the autonomous control server application.
