  • Publication number: 20240177002
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for training an actor neural network used to select actions to be performed by an agent interacting with an environment. One of the methods includes obtaining a minibatch of experience tuples; and updating current values of the parameters of the actor neural network, comprising: for each experience tuple in the minibatch: processing the training observation and the training action in the experience tuple using a critic neural network to determine a neural network output for the experience tuple, and determining a target neural network output for the experience tuple; updating current values of the parameters of the critic neural network using errors between the target neural network outputs and the neural network outputs; and updating the current values of the parameters of the actor neural network using the critic neural network.

  • Patent number: 11797234
    Abstract: A system includes a cluster of nodes including a storage domain, a memory, and a processor. The processor is configured to receive a request to determine an amount of allocated blocks associated with a virtual disk comprising a first volume. Each volume that includes metadata associated with allocated blocks is designated into a first set. Each volume within the one or more layers that lacks metadata associated with allocated blocks and includes an allocation table is designated into a second set. Each volume within the one or more layers that is omitted from the first set and second set is designated into a third set. The amount of allocated blocks within the first volume is determined based on inspecting the metadata of each volume of the first set, inspecting each allocation table of each volume of the second set, and inspecting each block of each volume in the third set.

  • Patent number: 10447670
    Abstract: Implementations of the disclosure provide for secret keys management in a virtualized data-center. In one implementation, a system is provided. The system comprising a memory to store secret key data and a processing device coupled to the memory. The processing device is to detect activation of a hypervisor on a host system. A request is received from a virtual machine (VM) associated with the hypervisor to access a data storage domain. A secret key providing authenticated access to a data storage device domain is registered to the hypervisor. The secret key includes a universally unique identifier (UUID). To register the secret key, the processing device is to store a data structure indicating an association between the UUID of the secret key and the hypervisor in a volatile memory associated with the processing device. Thereupon, the UUID of the secret key is transmitted to the hypervisor associated with the VM.

  • Patent number: 10241713
    Abstract: Mechanisms for snapshot management are provided. A request that requests that a first storage entity of type volume entity be generated is sent to an external storage service via an external interface. An entity chain associated with a virtual machine is generated. A first entry contains a first identifier (ID) that identifies the first storage entity, an entity type ID that identifies the first storage entity as a volume entity, and an active storage entity indicator. A first snapshot command is received. A request is sent to the external storage service via the external interface that requests that a second storage entity of type snapshot-volume entity be generated. A second entry is added to the entity chain that contains a second ID that identifies the second storage entity, an entity type ID that identifies the second storage entity as a snapshot-volume entity, and a reference to the first entry.
