  • Simulation of failure recovery within clustered systems
    Patent number: 7770063
    Abstract: Failure recovery within clustered systems is simulated. For each of a number of failure conditions for an initial state of a number of computing elements of a computerized system, a failure state of the computing elements is generated that corresponds to the failure condition and that is based on the initial state of the computing elements. A failure condition may include one or more hardware and/or software failures. For each failure state of the computing elements, a recovery state is then generated, or simulated, for the computing elements, based on the failure state and the initial state of the computing elements and on a number of recovery rules for the computing elements. Each recovery state is then output for subsequent analysis, where such analysis may be either with human interaction, or automatically and without human interaction.
