  • Patent number: 11651065
    Abstract: The present disclosure relates to methods and systems for evaluating a storage medium. The method may include receiving, via a user interface of a host, a user request to evaluate a storage medium coupled to a first controller. The method may also include determining whether there is a first binding history table associated with the storage medium stored in the host. In response to a determination that there is no first binding history table stored in the host, the method may include retrieving a binding history table from the storage medium via the first controller and determining the storage medium as a second-hand storage medium if there is at least one second controller different from the first controller in the binding history table.

  • Patent number: 11645006
    Abstract: A memory controller managing a memory device receives a memory read command from a host device that is communicably coupled to the memory device. The memory device includes a storage memory comprising a first type of memory cells and a cache memory comprising a second type of memory cells. The memory controller determines, from the memory read command, a physical address of a target memory location in the storage memory indicated by the memory read command. The memory controller executes a read operation on the target memory location corresponding to the physical address. The memory controller determines a read attribute of the target memory location. Conditioned on determining that the read attribute satisfies one or more threshold conditions, the memory controller programs an entry in the cache memory with information corresponding to the target memory location.

  • Patent number: 11640241
    Abstract: A data path connection can be established between a target of a remote source system and an initiator of a local destination system. A storage object of the remote source system exposed over such a data path connection can be mapped to a local storage object name of the local destination system. Such a remote storage object of the remote source system can be accessed as a local storage object of the local destination system using the local storage object name. Within the destination system, the local storage object name of the destination system can be used as a proxy to access the remote storage object of the remote source system. Accessing the remote storage object from the destination system can be used in several data mobility use cases, including, but not limited to, offloaded data copy across arrays, snapshot mobility and backup use-cases.

  • Patent number: 11614883
    Abstract: A distributed data storage system using erasure coding (EC) provides advantages of EC data storage while retaining high resiliency for EC data storage architectures having fewer data storage nodes than the number of EC data-plus-parity fragments. An illustrative embodiment is a three-node data storage system with EC 4+2. Incoming data is temporarily replicated to ameliorate the effects of certain storage node outages or fatal disk failures, so that read and write operations can continue from/to the storage system. The system is equipped to automatically heal failed EC write attempts in a manner transparent to users and/or applications: when all storage nodes are operational, the distributed data storage system automatically converts the temporarily replicated data to EC storage and reclaims storage space previously used by the temporarily replicated data. Individual hardware failures are healed through migration techniques that reconstruct and re-fragment data blocks according to the governing EC scheme.

  • Patent number: 11604608
    Abstract: Disclosed are computer-implemented methods, non-transitory computer-readable media, and systems for processing blockchain transactions. One computer-implemented method includes receiving M blockchain transactions and executing N blockchain transactions out of the M blockchain transactions in parallel using K threads of a first thread pool. A second thread pool is dedicated for accessing blockchain data stored in a storage system. For blockchain transactions distributed to each one of the K threads, one or more coroutines are used for each blockchain transaction so that the blockchain transactions are executed asynchronously using the coroutines. A blockchain block is generated to include the M blockchain transactions and added to a blockchain stored in the storage system.

  • Patent number: 11593020
    Abstract: Techniques are provided for consistent entity tags with multiple protocol data access. In an example, a file storage system is configured to process data according to file storage protocol(s) and object storage protocol(s). An object storage protocol can utilize entity tags that indicate whether an object (represented with a file in the file storage system) has changed. Where a file storage protocol is utilized to modify a file, an indication may be stored that indicates that the file lacks a valid entity tag. If an object storage operation is made to retrieve an object, and if the object corresponds to a valid entity tag, then that entity tag can be returned as part of the response. If the object does not correspond to a valid entity tag, then the file storage system can generate a new entity tag and return the newly generated entity tag as part of the response.

  • Patent number: 11586356
    Abstract: A processing device controls delivery of input-output (IO) operations from a host device to a storage system over selected paths through a network, and maintains counts of IO operations for each of a plurality of initiator-target pairs, the initiators being implemented on the host device and the targets being implemented on the storage system, each initiator-target pair being associated with a corresponding subset of the paths. Responsive to detection of at least a threshold number of errors relating to the IO operations for a given one of the initiator-target pairs, the processing device determines whether or not the detected errors satisfy one or more specified conditions based at least in part on the maintained count for that initiator-target pair, and responsive to the detected errors for the given initiator-target pair satisfying the one or more specified conditions, the processing device updates link performance issue information for the given initiator-target pair.
