Abstract:
Provided is a method of using a dynamic chunk allocation function to efficiently carry out data volume migration. A storage apparatus according to the present invention includes first and second storage units and divides a storage extent in the second storage unit into chunks to add the chunks to a chunk pool to dynamically allocate the chunks in the chunk pool to a newly created logical data volume (see FIG. 3).
