The first request includes a set of parameters in accordance with a defined interface and include a source area and a target area. The source area includes source ranges and source devices. Each of the source ranges identifies a portion of a logical address range of a different one of the source devices. The target area includes target ranges and target devices.

The first request is partitioned in to a plurality of other requests each of which is a request to copy a portion of source data located in the source area to a corresponding location in the target area.
