  • Patent number: 11036707
    Abstract: According to some embodiments, so-called “NS-Tree” indexes may be used to calculate whether all (or a portion) of two independent tables are consistent. The NS-Tree indexes may be comprised of various elements, e.g., a synchronization time, a primary key, a hash of the complete record itself, and an aggregate value associated with each index entry (e.g., an accumulated XOR value). At any point in the index, an entry may possess the accumulated aggregate value of all key entries in the table up to that point. That aggregate value may be used to validate data consistency with another table(s) maintaining the same index. Due to the unique composition of the NS-Tree index, users can also validate two data sets within a ‘sub-range’ of the entire data set. According to other embodiments, NS-Tree indexes may also be applied to two different clusters of nodes by applying the NS-Trees at a ‘federated’ level.

  • Patent number: 11036505
    Abstract: An arithmetic unit performs store-to-load forwarding based on predicted dependencies between store instructions and load instructions. In some embodiments, the arithmetic unit maintains a table of store instructions that are awaiting movement to a load/store unit of the instruction pipeline. In response to receiving a load instruction that is predicted to be dependent on a store instruction stored at the table, the arithmetic unit causes the data associated with the store instruction to be placed into the physical register targeted by the load instruction. In some embodiments, the arithmetic unit performs the forwarding by mapping the physical register targeted by the load instruction to the physical register where the data associated with the store instruction is located.

    Abstract: Embodiments presented herein describe techniques for deduplicating chunks of data across multiple clusters. A process executing in a storage system identifies one or more chunks in an incoming stream of data. For each chunk, a first fingerprint corresponding to the chunk is generated. The process determines whether the first fingerprint matches a second fingerprint listed in a corresponding entry in a deduplication map. Each entry of the deduplication map corresponds to a chunk stored in a location in one of the storage clusters. Upon determining that the first fingerprint matches the second fingerprint, the process writes, to a local persistent storage, a pointer referencing the location in that storage cluster.

    Abstract: Methods and systems for implementing network-aware caching are disclosed. Respective performance characteristics are determined for accessing a plurality of storage locations from a client computing device. The storage locations comprise one or more shared network-access storage locations accessible to the client computing device over a network and optionally one or more dedicated storage locations of the client computing device. One of the storage locations is selected for storing data to which access is requested by the client computing device. The selected storage location is determined based on the respective performance characteristics of the storage locations. The data is cached in the selected storage location.

  • Patent number: 10684994
    Abstract: One or more techniques and/or computing devices are provided for data synchronization. For example, an in-flight log may be maintained to track storage operations that are received by a first storage node, but have not been committed to both first storage of the first storage node and second storage of a second storage node that has a replication relationship, such as a disaster recovery relationship, with the first storage node. A dirty region log may be maintained to track regions within the first storage that have been modified by storage operations that have not been replicated to the second storage. Accordingly, a catchup synchronization phase (e.g., asynchronous replication by a resync scanner) may be performed to replicate storage operations (e.g., replicate data within dirty regions of the first storage that were modified by such storage operations) to the second storage until the first storage and the second storage are synchronized.

  • Patent number: 10684800
    Abstract: Processing within a computing environment that supports pageable guests is facilitated. Processing is facilitated in many ways, including, but not limited to, associating guest and host state information with guest blocks of storage; maintaining the state information in control blocks in host memory; enabling the changing of states; and using the state information in management decisions. In one particular example, the guest state includes an indication of usefulness and importance of memory contents to the guest, and the host state reflects the ease of access to memory contents. The host and guest state information is used in managing memory of the host and/or guests.

  • Patent number: 10657005
    Abstract: A method for efficiently managing extents of backup volumes in a tiered storage system is disclosed. In one embodiment, such a method includes identifying a lifespan associated with a backup volume. The lifespan indicates how long extents of the backup volume are retained in a tiered storage system before being released. The method further assigns a temperature value to the extents that determines where the extents are stored in the tiered storage system. The method utilizes the lifespan to determine the temperature value, where the temperature value is inversely proportional to the lifespan. The method places the extents on tiers of the tiered storage system in accordance with their temperature value, such that higher temperature extents are placed on higher tiers of the tiered storage system, and lower temperature extents are placed on lower tiers of the tiered storage system. A corresponding system and computer program product are also disclosed.

  • Patent number: 10628074
    Abstract: Example tiered storage systems, storage devices, and methods provide tier configuration for routing of data commands by peer storage devices. Each tiered storage device is configured to communicate with a plurality of peer storage devices with storage device identifiers. Each storage device is assigned to a performance tier in a tier configuration that determines which host data tier should be stored in the storage media of the storage device, the local performance tier for the storage device. If the local performance tier of the storage device does not match the host data tier for a data command or stored data element when the storage device determines the host data tier, the storage device selectively forwards the host data to another peer storage device with the performance tier that matches the host data tier.

  • Patent number: 10599622
    Abstract: A distributed storage system stores a storage volume as segments that are allocated as needed and assigned VSIDs according to a monotonically increasing counter. The storage volume may be provisioned by an orchestration layer that manages the storage volumes as well as containers executing executable components of the storage volume. A storage volume may be stored across multiple tiers with a storage node managing on which tier a segment is stored based on a volume tier policy and usage of the segments. The tiering policy may be used to relocate the entire storage volume to a tier, such as a cloud computing platform, after which an application may be restored on the tier. Segments on a tier with built in redundancy may be used as both primary and backup copies.

  • Patent number: 10599351
    Abstract: One or more storage systems are connected to one or more storage boxes comprising multiple storage devices. Multiple storage areas provided by one or more storage boxes include an allocated area, which is a storage area that is allocated to a virtual volume, and an empty area, which is a storage area that is not allocated to any logical volume. Multiple owner rights corresponding to multiple storage areas are set in one or more storage systems. A storage system having an empty area owner right changes an empty area to the allocated area by allocating the empty area. In a case where a configuration change (a relative change in the number of storage boxes with respect to the number of storage systems) is performed, a first storage system that exists after the configuration change sets, in the first storage system, either more or fewer owner rights than the owner rights, which have been allocated to the first storage system before the configuration change.
