Panzura Assigned Two Patents

Performing deduplication in distributed filesystem
Panzura, Inc., Campbell, CA, has been assigned a patent (9,679,040) developed by Davis, Andrew P., Santa Cruz, CA, Taylor, John Richard, Tiburon, CA, and Chou, Randy Yen-pang, San Jose, CA, for a “performing deduplication in a distributed filesystem.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The disclosed embodiments provide techniques for performing deduplication for a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems, the cloud controllers cache and ensure data consistency for the stored data. During operation, a cloud controller receives an incremental metadata snapshot that references new data that was added to the distributed filesystem by a remote cloud controller. The cloud controller extracts a set of deduplication information from this incremental metadata snapshot. Upon receiving a subsequent client write request, (e.g., a file write that includes one or more data blocks, the cloud controller uses the extracted deduplication information to determine that one or more data blocks) in the client write request have already been written to the distributed filesystem.“

The patent application was filed on February 15, 2013 (13/769,200).

Deleting file from distributed filesystem
Panzura, Inc., Campbell, CA, has been assigned a patent (9,678,968) developed by Taylor, John Richard, Tiburon, CA, Chou, Randy Yen-pang, San Jose, CA, and Davis, Andrew P., Santa Cruz, CA, for a “deleting a file from a distributed filesystem.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The disclosed embodiments disclose techniques for deleting a file from a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems, the cloud controllers store metadata for the distributed filesystem, and cache and ensure data consistency for the data stored in the cloud storage systems. During operation, a cloud controller receives a request from a client to delete a file from the distributed filesystem. The cloud controller updates a user view of the distributed filesystem to present the appearance of the target file being deleted to the client, and then initiates a background deletion operation to delete the target file without negatively affecting the performance of the other users of the distributed filesystem.“

The patent application was filed on February 15, 2013 (13/769,194).
