ABSTRACT:
A method for evaluating failure in an electronic data storage system that includes defining a data storage system in terms of its multiple storage components that are operably interconnected to store and retrieve electronic data. Failed storage components are detected and then evaluated to provide a degree of failure for that particular storage component. The data storage system is then analyzed at the system level for any diminished usability in view of the failed storage component and its degree of failure. This diminished usability can be translated into an effect on the data availability within the data storage system. The impact on data availability is reported to the user so that the user can make intelligent decisions which might preempt system-wide failure. A data storage system with failure evaluation is also described.
