  • Patent number: 11494213
    Abstract: Systems and methods for virtual machine memory migration by storage are provided. A method includes receiving a request to migrate a virtual machine from a source host to a destination host. The method further includes mapping, by the source host, a memory of the virtual machine to a storage device accessible over a network by the source host and by the destination host. The method further includes caching, by the source host, a portion of a state of the virtual machine. The method further includes issuing a synchronization command to synchronize the portion of the state of the virtual machine with the storage device. Responsive to determining that a time period to complete the synchronization command is below a threshold time period, the method further includes stopping the virtual machine on the source host. The method further includes starting the virtual machine on the destination host.

  • Patent number: 11435807
    Abstract: Proxy-less power management using an automation engine is disclosed. An entity manager executing on a computing device determines that a first entity requires a power management function to be performed against the first entity. The entity manager generates power management execution information that identifies a power device address of a power management device that controls the first entity. An automation engine is initiated on the computing device with the power management execution information to cause the power management function to be performed against the first entity via the power management device based on the power management execution information.

  • Patent number: 11429935
    Abstract: A method for historically synchronizing tag data related to a computer network is provided. A network management server compares a relations table of entities from a first database to a corresponding relations history table of entities from a second database. The network management server identifies from the comparison a pair of entities having a changed relationship. The network management server updates the relations history table of entities with the changed relationship in the second database. The network management server updates a path and level between a root of a tree of tags and each tag of the pair of tags in a historical configuration details table of tags in the second database based on updating the relations history table of entities.

  • Patent number: 11275659
    Abstract: A system includes a memory and a processor in communication with the memory. The processor builds a preliminary history list of a plurality of commits including intermediary commits and a target commit, instantiates a target file list of files modified by the target commit, and instantiates an intermediary file list for each intermediary commit. Additionally, the processor classifies each intermediary commit as an intersecting commit or an empty commit. Responsive to classifying a respective intermediary commit as an empty commit, the processor removes the respective intermediary commit from the preliminary history list to create a candidate history list. Responsive to classifying a respective intermediary commit as an intersecting commit, the processor retains the respective intermediary commit in the candidate history list. Additionally, the processor joins the respective intermediary file list with the target file list and creates a finalized history list.
