  • Consistent transition from asynchronous to synchronous replication in hash-based storage systems
    Patent number: 10534547
    Abstract: A System, computer program product, and computer-executable method of transitioning replication on a data storage system including a production site and a replication site from asynchronous replication to synchronous replication, the System, computer program product, and computer-executable method including receiving a request to transition from asynchronous replication to synchronous replication and changing the data storage system to a transition mode, wherein the data storage system transitions the data storage system from using asynchronous replication to synchronous replication.
    Type: Grant

  • Snapshot mechanism
    Patent number: 10445184
    Abstract: A memory management system for a thinly provisioned memory volume in which a relatively larger virtual address range of virtual address blocks is mapped to a relatively smaller physical memory comprising physical memory blocks via a mapping table containing entries only for addresses of the physical memory blocks containing data. The memory management system comprises a snapshot provision unit to take a given snapshot of the memory volume at a given time, the snapshot comprising a mapping table and memory values of the volume, the mapping table and memory values comprising entries only for addresses of the physical memory containing data. The snapshot is managed on the same thin provisioning basis as the volume itself, and the system is particularly suitable for RAM type memory disks.

  • Scalable block data storage using content addressing
    Patent number: 9104326
    Abstract: A device for scalable block data storage and retrieval uses content addressing. Data storage devices store data blocks, and are connected over a network to computing modules. The modules comprise control modules and data modules and carry out content addressing for both storage and retrieval. The network defines separate control paths via the control modules and data paths via the data modules.
