Abstract
A technique balances data storage activity within a mapped-RAID environment. The technique involves selecting, by processing circuitry, a source slice of storage from multiple slices of storage of the mapped-RAID environment, the source slice containing particular data to be relocated. The technique further involves selecting, by the processing circuitry, a destination slice of storage from the multiple slices of storage of the mapped-RAID environment. The technique further involves relocating, by the processing circuitry, the particular data from the source slice to the destination slice to balance data storage activity within the mapped-RAID environment. The mapped-RAID environment includes multiple storage devices. Each storage device provides multiple non-overlapping device extents. Each slice of the multiple slices of storage of the mapped-RAID environment is formed of storage stripes extending across device extents provided by a group of storage devices that includes less than all of the storage devices of the mapped-RAID environment.
