Storage management apparatus, a storage management method and a storage management program
Abstract:
A storage management apparatus performs migration considering an I/O load that will be generated during migration between a source array group and a destination array group. To migrate data from the source array group to the destination array group, a bandwidth that is available for use between the source and destination array groups is calculated. A volume that is within the source array group, and that has a write I/O amount that is smaller than the calculated bandwidth, is selected as the source volume for the migration, wherein the write I/O amount is the information transmission amount of information that is written. Data is thus migrated from the selected volume to the movement destination array group.
