  • Method and apparatus for deterministically identifying sets of snapshots on a storage system
    Patent number: 11762807
    Abstract: Snapsets containing snapshots from a group of storage volumes are assigned snapset IDs. The same snapset ID is applied to each snapshot of the snapset, and is a globally unique value within the storage system. The snapset ID is assigned to a snapshot upon creation, and remains the same regardless of creation or deletion of other snapshots on the storage volume. By assigning a snapset ID to each snapshot of the snapset, and maintaining the snapset ID as a constant value as long as the snapshot is maintained on the storage system, it is possible to easily determine which snapshots form a given snapset. Control operations on particular storage groups or across storage groups are implemented by specifying particular actions to be taken on snapsets or snapshots, which are identified using the snapset IDs.

  • Optimal port selection for data migration
    Patent number: 11086522
    Abstract: Automated port selection for data migration includes an algorithm that selects a set of SAN ports with the following properties: the selected ports have the least port utilization among all possible port selections; the number of independent data paths between the selected ports is no smaller than a user configurable minimum number; and the difference between the aggregate bandwidth of the ports on both arrays is minimized.
