Abstract
Techniques are disclosed which monitor the distribution of I/O activity across the storage drives of a data storage system and detect non-uniform distributions of I/O operations across the storage drives by monitoring I/O operations directed to disk extents supporting mapped RAID extents. In response to detecting non-uniform distributions of I/O operations across the storage drives, these techniques identify LUNs with non-uniform I/O patterns and redistribute data stored in those LUNs across RAID extents supporting those LUNs.
