  • Patent number: 11416452
    Abstract: Described are a method, system, and computer program product for deduplicating a storage object. A hash of a window of data of a storage object is determined and a determination is made as to whether the window of data of the storage object corresponds to a chunk boundary. A determination is made as to whether the hash of the object matches one pseudo fingerprints in a list of at least one pseudo fingerprint. A storage object chunk boundary based on the window of data is stored in response to the window of data corresponding to the chunk boundary or in response to determining that the hash of the object matches one of the pseudo fingerprints. A determination is made of a new window of data in the storage object following the window of data when the window of data is not an end of data of the storage object.

  • Patent number: 11403150
    Abstract: Provided is a system for managing the resource limit associated with a user, where the resource limit indicates the amount of compute resources the user is allowed to use. As the user requests and obtains additional resources from a pool of resources, the user's resource usage is increased to reflect the additional resources being used by the user. As the resources used by the user are released, to ensure that the pool of resources has sufficient capacity to handle additional resource requests, the replenishment status of the pool is further checked, and if the replenishment status satisfies a condition for updating the user's resource usage, the user's resource usage is decreased to reflect the resources that are no longer in use by the user. The released resources are torn down and re-provisioned back into the pool of resources.

  • Patent number: 11347409
    Abstract: A primary storage system appends a red-hot data indicator to each track of data transmitted on a remote data facility during an initial synchronization state. The red-hot data indicator indicates, on a track-by-track basis, whether the data associated with that track should be stored as compressed or uncompressed data by the backup storage system. The red-hot data indicator may be obtained from the primary storage system's extent-based red-hot data map. If the red-hot data indicator indicates that the track should remain uncompressed, or if the track is locally identified as red-hot data, the backup storage system stores the track as uncompressed data. If the red-hot data indicator indicates that the track should be compressed, the backup storage system compresses the track and stores the track as compressed data. After the initial synchronization process has completed, red-hot data indicators are no longer appended to tracks by the primary storage system.

  • Patent number: 11342008
    Abstract: The invention relates to a method, and an apparatus for accessing to data in response to a power-supply event. The method, performed by a flash controller, includes steps for: repeatedly detecting whether a voltage supplied to the flash controller is lower than a first threshold; and issuing a program command to a flash module for programming data into the flash module and performing a supervision procedure when the voltage is lower than the first threshold. The supervision procedure includes steps for: repeatedly detecting whether the voltage is lower than a second threshold during a time period when issuing the program command to the flash module until transmitting the data to the flash module completely; and cancelling the program command when the voltage is lower than the second threshold.

  • Patent number: 11334443
    Abstract: A method and system for verified data restoration in storage systems is described. The method may include calculating a hash sum relating to initial data for storing in an archive and storing the data into the archive and storing the calculated initial hash sum into a blockchain network. The method may further include retrieving the data from the archive and calculating a retrieved hash sum of the retrieved data. The method may also include comparing the initial hash sum from the blockchain network with the retrieved hash sum. The method may additionally include restoring the data from the archive if the initial hash sum is equivalent to the retrieved hash sum.

  • Patent number: 11330052
    Abstract: Certain embodiments disclosed herein reduce or eliminate a communication bottleneck at the storage manager by reducing communication with the storage manager while maintaining functionality of an information management system. In some implementations, a client obtains information for enabling a secondary storage job (e.g., a backup or restore) from a storage manager and stores the information (which may be referred to as job metadata) in a local cache. The client may then reuse the job metadata for multiple storage jobs reducing the frequency of communication with the storage manager. When a configuration of the information management system changes, or the availability of resources changes, the storage manager can push updates to the job metadata to the clients. Further, a client can periodically request updated job metadata from the storage manager ensuring that the client does not rely on out-of-date job metadata.
