Abstract
A system and methods employ a redistribution module to predict whether there is data stored in an arrayed storage device that is likely to be data that will be highly accessed in the future. The redistribution module locates high-access data on one or more storage components within the array and redistributes it evenly across all storage components in the array so that no single storage component contains a disproportionate amount of the high-access data. Redistributing high-access data evenly across all storage components (e.g., disks) in a storage array helps prevent I/O (input/output) bottlenecking at any single storage component in the array. I/Os are serviced in a more parallel manner which increases the overall performance of the storage array.
