  • Patent number: 11119977
    Abstract: Cognitive compression with varying structural granularities in a NoSQL database by establishing a data training set for compressing and decompressing data stored within the NoSQL database. The data training set includes received user policy goals, compression parameters, and metered feedback associated with data usage and workload characteristics. A compression parameter model is dynamically implemented in real-time for the data selected according to the established data training set to compress and decompress the data at a given structural granularity.

  • Patent number: 11068465
    Abstract: In one embodiment, a computer-implemented method for object-granular policy assignment in an object storage environment includes: automatically assigning a plurality of objects stored within the object storage environment to one or more policies; and locating one or more of the objects among a plurality of policy rings within the object storage environment based on semantics of the one or more policies. A virtual namespace maps each object to at least one of the policy rings based on the one or more policies assigned to the object; and the virtual namespace is scalable with a number of the plurality of objects stored within the object storage environment. Corresponding systems and computer program products are also disclosed.

  • Publication number: 20190187904
    Abstract: A method includes determining a data record partition size based on resources used for transferring data from a higher storage tier that comprises first memory to one or more lower storage tiers that comprise second memory, determining a distribution mapping of the first memory, identifying all sets of contiguously stored data records on the higher storage tier that are suitable for export and greater in size than the data record partition size, sending a list of sets of contiguously stored data records to an exporter, transmitting from the higher storage tier to the one or more lower storage tiers, by the exporter, each set of contiguously stored data records, and transmitting from the higher storage tier to the one or more lower storage tiers, all remaining data records that are suitable for export and are not included on the list of logically sorted sets of contiguously stored data records.

  • Patent number: 10305516
    Abstract: Embodiments relate to a system with multiple erasure codes, and selecting and encoding for a write file with one of the codes to mitigate costs associated with storage recovery. The codes include a fast recovery code for frequently accessed data and a higher storage efficiency code for less frequently accessed data. State data is tracked to ascertain frequency of access to the file. One of the erasure codes is dynamically selected based on the tracked data, with the focus of the code select to lower recovery costs, and the data is encoded with the selected erasure code. Accordingly, the original coding of the write file is subject to change based on the tracked state data.

  • Patent number: 10296215
    Abstract: In one embodiment, a method includes determining a data record partition size based on resources used for transferring data from a higher storage tier to one or more lower storage tiers. The method also includes determining which data records stored to the higher storage tier are suitable for export to the one or more lower storage tiers, determining a distribution mapping of the first memory, the distribution mapping indicating a relative distribution of storage locations for all of the data records that are stored to the higher storage tier, identifying all sets of contiguously stored data records on the higher storage tier that are suitable for export and greater in size than the data record partition size, logically sorting, in a descending order of size, the sets of contiguously stored data records, and sending a list of logically sorted sets of contiguously stored data records to an exporter.

  • Patent number: 10242014
    Abstract: A filesystem includes a pool of data blocks and a pool of index blocks. Non-overlapping subpools of data blocks, including a first subpool of data blocks and a second subpool of data blocks, are identified within the pool of data blocks. Likewise, non-overlapping subpools of index blocks, including a first subpool of index blocks and a second subpool of index blocks, are identified within the pool of index blocks. A first file group is mounted within a global namespace on a first mount point on the filesystem. A second file group is also mounted within the global namespace on a second mount point on the filesystem. The first subpool of data blocks and the first subpool of index blocks are allocated to the first mounted file group, and the second subpool of data blocks and the second subpool of index blocks are allocated to the second mounted file group.

  • Patent number: 10127097
    Abstract: The present disclosure describes systems and methods for propagating port state to intermediary devices of a cluster in a static link aggregation environment. The methods and systems include a cluster comprising a plurality of intermediary devices in communication with a network device via a static link aggregation comprising aggregated ports from different intermediary devices of the cluster. A first device of the static link aggregation is configured to detect that a health of the first device is below a predetermined threshold and, responsive to the detection, identify one or more ports in the aggregated ports as down. A second device of the link aggregation is configured to, responsive to the identification, remove the ports from a distribution list for the static link aggregation. Upon detection that a health of a device is above a predetermined threshold, the first device may identify the ports as up.
