  • Systems and methods for enabling replication targets to reclaim unused storage space on thin-provisioned storage systems
    Patent number: 9965224
    Abstract: A computer-implemented method for enabling replication targets to reclaim unused storage space on thin-provisioned storage systems may include: 1) replicating data from a replication source to a replication target, 2) identifying unused storage space within the replicated data, 3) generating a reclamation request for reclaiming the unused storage space from a thin-provisioned storage system that provides thin-provisioned storage for the replication target, and then 4) issuing the reclamation request to the thin-provisioned storage system in order to reclaim the unused storage space from the thin-provisioned storage system. Various other related systems, methods, and configured computer-readable media are also disclosed.

  • Method and system of providing exclusive and secure access to virtual storage objects in a virtual machine cluster
    Patent number: 8495323
    Abstract: A system, method, and medium for implementing I/O fencing in a virtual machine cluster sharing virtual storage objects. A volume manager driver receives access requests from virtual machines directed to a virtual storage object such as a volume. The volume manager driver then translates the access request to point to a storage device underlying the volume. The access request includes keys and/or other group reservation data required to implement an I/O fencing method so as to prevent access to shared data by malfunctioning or non-responsive virtual machines.
