Patent number: 11126591Abstract: Example apparatus and methods identify files that are so small or so large that they compromise the efficient operation of a file system that uses re-assignable one-to-one inodes and inode numbers. Small files are aggregated into collections of files and large files are subdivided into collections of smaller files. Information for locating multiple related files with fewer lookups is generated and stored in a folder. An inode having a new type of inode number is then created. The new type of inode number encodes information for finding the folder. The encoded information may include a folder identifier that acts as a primary key into a database that is configured to locate a member of the aggregated or subdivided files with a single lookup. A filter file system may be updated with the new inode. The new inode number is unique within the filter file system and may not be re-assigned.Type: GrantFiled: October 31, 2019Date of Patent: September 21, 2021Assignee: Quantum CorporationInventors: Roderick B. Wideman, Don Doerner, Michael Zeis

Patent number: 10853187Abstract: Methods and apparatus deduplicate and erasure code a message in a data storage system. One example apparatus includes a first chunking circuit that generates a set of data chunks from a message, an outer precoding circuit that generates a set of precoded data chunks and a set of parity symbols from the set of data chunks, a second chunking circuit that generates a set of chunked parity symbols from the set of parity symbols, a deduplication circuit that generates a set of deduplicated data chunks by deduplicating the set of precoded chunks or the set of chunked parity symbols, an unequal error protection (UEP) circuit that generates an encoded message from the set of deduplicated data chunks, and a storage circuit that controls the data storage system to store the set of deduplicated data chunks, the set of parity symbols, or the encoded message.Type: GrantFiled: February 26, 2019Date of Patent: December 1, 2020Assignee: Quantum CorporationInventors: Suayb S.

Patent number: 10496523Abstract: An example method includes determining a configuration of two or more partitions for a sequential access medium. At least one partition stores data de-duplication data structures while at least one other partition stores a repository of unique data blocks associated with the data structures. The method also includes controlling a data de-duplication computer to configure the sequential access medium according to the configuration. The method includes producing an output sequence for writing the data structures and a set of unique data blocks associated with the set of data structures to the sequential access medium as configured with the two or more partitions. One embodiment includes controlling a data de-duplication computer to write the data de-duplication data structures and the set of unique data blocks to the sequential access medium according to the output sequence.Type: GrantFiled: December 20, 2016Date of Patent: December 3, 2019Assignee: Quantum CorporationInventor: Roderick B.

Patent number: 10484016Abstract: Example apparatus and methods combine erasure coding with data deduplication to simultaneously reduce the overall redundancy in data while increasing the redundancy of unique data. In one embodiment, an efficient representation of a data set is produced by deduplication. The efficient representation reduces duplicate data in the data set. Redundancy is then added back into the data set using erasure coding. The redundancy that is added back in adds protection to the unique data associated with the efficient representation. How much redundancy is added back in and what type of redundancy is added back in may be controlled based on an attribute (e.g., value, reference count, symbol size, number of symbols) of the unique data. Decisions concerning how much and what type of redundancy to add back in may be adapted over time based, for example, on observations of the efficiency of the overall system.Type: GrantFiled: May 23, 2017Date of Patent: November 19, 2019Assignee: Quantum CorporationInventors: Roderick B.

Patent number: 10474571Abstract: Example apparatus and methods provide improved reclamation, garbage collection (GC) and defragmentation (defrag) for data storage devices including solid state drives (SSD) or shingled magnetic recording (SMR) drives. An erasure code (EC) layer that facilitates logically or physically erasing data from the SSD or SMR as a comprehensive GC or defrag is added to the SSD or SMR. Erased data may be selectively recreated from the EC layer as needed. Pre-planned EC write zones may be established to further optimize GC and defrag. Recreated data may be written to selected locations to further optimize SSD and SMR performance. Erasure code data may be distributed to co-operating devices to further improve GC or defrag. Example apparatus and methods may also facilitate writing data to an SMR drive using tape or VTL applications or processes and providing a pseudo virtual tape library on the SMR drive.Type: GrantFiled: June 9, 2017Date of Patent: November 12, 2019Assignee: Quantum CorporationInventors: Roderick B.

Patent number: 9876746Abstract: Example methods and apparatus associated with a messaging policy controlled email deduplication are provided. In one example a messaging policy is accessed. It is determined whether a received message complies with the policy based on rules of the messaging policy. If a message complies with the messaging policy, the message is displayed. If the message does not comply with the messaging policy, it is determined whether the message is duplicative. If the message is deemed duplicative it is not displayed. Conversely, if the message is not deemed duplicative it is displayed.Type: GrantFiled: October 16, 2014Date of Patent: January 23, 2018Assignee: Quantum CorporationInventor: Roderick B. Wideman
