  • Patent number: 10776258
    Abstract: A method is disclosed for avoiding out-of-space conditions in an asynchronous data replication environment. In one embodiment, such a method creates a consistency group on a primary storage system of an asynchronous data replication environment. The method determines a number of additional extents that will be needed on a secondary storage system to accommodate the consistency group. The number of additional extents is compared to a number of free extents on the secondary storage system. In the event the number of additional extents does not exceed the number of free extents, the method transfers the data from the primary storage system to the secondary storage system. In the event the number of additional extents exceeds the number of free extents, the method automatically takes actions on the secondary storage system to provide the number of additional extents. A corresponding system and computer program product are also disclosed.

  • Patent number: 10733060
    Abstract: One general aspect of asynchronous local and remote generation of consistent point-in-time snap copies in consistency groups in accordance with the present description, is directed to receiving a local-remote pair point-in-time snap copy establish command to establish a local point-in-time snap copy in a local data storage system, and a remote point-in-time snap copy in a remote data storage system. In one aspect, establishment of the remote point-in-time snap copy relationship may be delayed as a function of the state of a consistency group formation process upon receipt of the local-remote pair point-in-time snap copy establish command. As a result, consistency of the local-remote pair of point-in-time snap copies may be realized, notwithstanding an asynchronous relationship between the local and remote storage systems. Other features and aspects may be realized, depending upon the particular application.

  • Publication number: 20200117749
    Abstract: A method for more intelligently managing storage space in journal volumes is disclosed herein. In one embodiment, such a method includes maintaining, on a primary storage system, a change recording data structure that documents updated storage elements of a primary volume on the primary storage system. The method further determines in which extents of the primary volume the updated storage elements reside. These extents are recorded in an extent-based data structure. The method transmits the extent-based data structure from the primary storage system to a secondary storage system that is in an asynchronous mirroring relationship with the primary storage system. The extent-based data structure is then read at the secondary storage system. The method frees, from a journal volume on the secondary storage system, extents that are not recorded in the extent-based data structure. A corresponding system and computer program product are also disclosed herein.
