  • Patent number: 11928492
    Abstract: Techniques are provided for managing quality of service (QoS) policies in a virtual storage environment. A data storage system receives a request from a host system to connect to a target virtual volume in a storage array of the data storage system, and determines a protocol endpoint which has an assigned QoS policy which corresponds to a QoS policy of the target virtual volume. The data storage system binds the target virtual volume to the protocol endpoint which is determined to have an assigned QoS policy which corresponds to the QoS policy of the target virtual volume, and sends a unique identifier of the protocol endpoint, which is bound to the target virtual volume, to the host system. The data storage system utilizes the protocol endpoint, which is bound to the target virtual volume, to handle data access requests received from the host system for accessing the target virtual volume.

  • Patent number: 11928228
    Abstract: Facilitating an object protocol based access of data within a multiprotocol environment is presented herein. In response to receiving a simple storage system (S3) protocol based request to access data via a storage device of a filesystem, the filesystem determines a type of S3 bucket that represents the data; and based on the type of S3 bucket, the filesystem facilitates an S3 protocol based access of the data via the storage device. For example, the S3 protocol based request comprises a file request to create, read, write, and/or delete a file within the storage device. In another example, the S3 protocol based request comprises an object request to create, modify, read, and/or delete an object within the storage device.

  • Patent number: 11928091
    Abstract: Embodiments include a method of storing digital data in a blockchain by receiving the digital data from a user, deduplicating the data in a deduplication system of the user to form deduplicated data, and encoding the deduplicated data into an array format for storage on a blockchain. A smart contract is deployed for deduplication on the destination side of the data, and the deduplicated data is encoded into a Binary Aligned Map (BAM) format for storage on the blockchain. A process on the destination side stores the deduplicated array data as a next block in the blockchain only if the next block agrees with the smart contract, and the blockchain is stored in system storage comprising hard disk, solid state, tape, or optical devices.

  • Patent number: 11921747
    Abstract: Replication operations of replicating data from a production site to a replica site. The replication is performed using independent Merkle trees. The Merkle trees are updated asynchronously using Merkle trees that have been augmented with a time-based value. The synchronization is verified by comprising root hashes of the independent Merkle trees at certain points in time. The replication and Merkle trees are self-healing and trigger a resynchronization when a discrepancy is discovered.

  • Patent number: 11921590
    Abstract: A three-phase full quorum commit method enabling backing up of network devices that do not offer direct hooks in order to have application consistent protection. Devices are verified to be ready to perform a backup, and a condition of reaching and maintaining a full quorum of devices within a maximum time period is required before the system can be backed up. The three phase backup process reduces the chance of changes to network devices from corrupting consistency among the saved states of the different and disparate network devices. Multiple devices of different makes and models participate together as a unified backup as a network partition and all devices are verified as being in a ready state. The device configuration data is moved from device memory to local disk, and can then be tiered to secondary storage.
