Abstract
Data associated with a workload is stored in a first composite array of data storage devices, and is automatically stored in a second composite array in response to predicting failure of one of the data storage devices in the first composite array. The data may be stored in the second composite array by either converting the first composite array or migrating the data to the second composite array. One of the data storage devices may predict its own failure and issue a predictive failure alert.
