Abstract
Techniques for processing data involve: receiving a request for moving data from a first slice group in a first logical unit to a second logical unit; determining, based on the request, a second slice group from the second logical unit, the size of the second slice group being larger than or equal to the size of the first slice group; and moving data in the first slice group into the second slice group. Such techniques enable moving data into slices in a specified address range in a specified logical unit, moving data into appropriate slices in a target logical unit when data cannot be moved to slices in a specific address range because an address range is not specified or a specified address range is unavailable can be achieved, and moving disk extents (DEs) by a Redundant Array of Multi-Core Disks (MCR) and redistributing IOs between disk extents.
