  • Managing storage devices in a distributed storage system
    Patent number: 10372329
    Abstract: Storage systems store data in a storage pool comprising storage devices or virtual devices. The storage pool may be allocated for a particular purpose. If a virtual device within the storage pool needs to be repurposed, the virtual device is removed from the storage pool. Data is moved from the removed virtual device to one or more target virtual devices. Segments of the source virtual device being removed are copied to target virtual devices. Mapping tables associating source segments with target segments are stored. If the storage system receives a request to access data stored on a virtual device that is removed, the storage system processes the mapping tables to determine where the data is stored.

  • Retrieving point-in-time copies of a source database for creating virtual databases
    Patent number: 10346369
    Abstract: A storage system maintains copies of a source database to allow virtual databases to be provisioned. Transaction logs received from the source database are applied to database blocks stored in the storage system to update the database blocks. The storage system checks if there are defect in the transaction logs of the source database. If a defect in transaction logs is detected, the storage system obtains a latest copy of the source database. The storage system matches database blocks of the received copy with database blocks already available in the storage system to determine whether a corresponding database block is already available in the storage system. If a received database block is different from database blocks already available at the storage system, the received database block is stored in the storage system. The database blocks may be matched using a hash value of the database blocks.
