Internal striping inside a single device

A computer program product for performing internal striping within a subset of slices, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable and/or executable by a processor to cause the processor to perform a method comprising:

• receiving, by the processor, a logical unit;
• splitting, by the processor, the logical unit into a plurality of data chunks;
• and
• distributing, by the processor, the plurality of data chunks across the subset of slices such that the plurality of data chunks are striped across the subset of slices, and striped across a plurality of physical partitions in each of the subset of slices,
• wherein the subset of slices are in a single physical storage module in a single storage device.

A system comprising:

• a processor;
• and
• logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
• receive, by the processor, a logical unit;
• split, by the processor, the logical unit into a plurality of data chunks;
• and
• distribute, by the processor, the plurality of data chunks across a subset of slices such that the plurality of data chunks are striped across the subset of slices, and striped across a plurality of physical partitions in each of the subset of slices,
• wherein the subset of slices are in a single physical storage module in a single storage device,
• wherein the single storage device includes a collection of successive partitions which are grouped together and managed as a single internally striped entity.
