Abstract
In certain techniques, a plurality of storage devices of a storage system are sorted into a sequence of storage devices by capacity. A first number of at least one storage device with maximum capacity in the sequence of storage devices is determined. A group of storage devices are selected from the sequence of storage devices based on the first number, a device number of storage devices in the sequence and a threshold device number, the number of storage devices in the group of storage devices being less than or equal to the threshold device number. A user storage system is built based on storage space in the group of storage devices, the user storage system having a predetermined width for representing a sum of a data width and a parity width in one stripe of the user storage system. Accordingly, efficiency of storage space utilization can be improved.
