  • Systems and methods for automatic repair and replacement of networked machines
    Patent number: 7302608
    Abstract: Systems and methods for automatic repair and replacement of computing machines are disclosed. The system may generally include a database including configuration information for the available replacement machines and a failed machine, a machine assignment module to assign a replacement machine based on a comparison of the configuration information for the failed machine and the available replacement machines, and a configuration module for generating configuration data for replacement of the failed machine with the replacement machine in the computer network. The machine assignment module may compare certain configuration parameters such as processor speed, disk drive size, and/or amount of RAM, between the failed machine and the available replacement machines. A replacement module may copy data from another copy of the failed machine in the computer network into the replacement machine. An installation module may install the configuration data in, e.g., dependent machines, and restart the dependent machines.
