Abstract
Data associated with a workload is stored in a first composite array of data storage devices that meets first data storage requirements of the workload, and is automatically stored in a second composite array in response to detecting second data storage requirements of the workload, wherein the second composite array of data storage devices meets the second data storage requirements. The data may be stored in the second composite array by either converting the first array or migrating the data to another array that more closely meets the current data storage requirements of the workload. Alternatively, the array conversion or the data migration may be performed in response to a predictive failure alert from one of the data storage devices in the first composite array.
