Qumulo Assigned Three Patents

Access verification for distributed file systems
Qumulo, Inc., Seattle, WA, has been assigned a patent (10,614,241) developed by Kirby, Michael Patrick, Lynnwood, WA, Peet, Iain Michael Christopher, Low, Anthony Moon-Git, Martynov, Aleksei, and Sturgeon, Jason Allan, Seattle, WA, for an “access verification for distributed file systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Managing data in a file system with a verification engine that may obtain a user identifier associated with a user, an object identifier, and a target object. The verification engine may determine target identities associated with two or more file system protocols based on the user identifier. The verification engine may determine permission entries associated with the two or more file system protocols associated and the target object. The verification engine may employ the target identities and the permission entries to directly verify access rights to the target object for the user. Accordingly, the verification engine may provide a report that includes the target identities, the permission entries, or the access rights.”

The patent application was filed on December 27, 2018 (16/234,334).

Client aware pre-fetch policy scoring
Qumulo, Inc., Seattle, WA, has been assigned a patent (10,614,033) developed by Rothschilds, Thomas Gregory, Unger, Thomas R., Youngblut, Eric E., and Godman, Peter J., Seattle, WA, for a “client aware pre-fetch policy scoring system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Embodiments are directed to managing data in a file system. A pre-fetch engine may receive requests from a client the file system that includes a pre-fetch storage tier and a file storage tier of storage devices. The pre-fetch engine determines a pre-fetch policy based on the requests such that the pre-fetch policy determines which blocks to copy to the pre-fetch storage tier. And, the pre-fetch policy may be associated with a score model that includes score rules where one of the rules may be associated with a client score. The pre-fetch engine may obtain scores associated with the score rules such that the scores are based on previous requests made by the client. In response to scores exceeding a threshold value, the pre-fetch engine may copy the blocks to the pre-fetch storage tier. The pre-fetch engine may update the scores based on the performance of the pre-fetch policy.”

The patent application was filed on January 30, 2019 (16/262,790).

Continuous replication for secure distributed filesystems
Qumulo, Inc., Seattle, WA, has been assigned a patent (10,606,812) developed by Cooper, Ezra Elias Kilty, Fachan, Neal Thomas, Liang, Junjie, O’Neill, Kevin Ross, and Chmiel, Michael Anthony, Seattle, WA, for a “continuous replication for secure distributed filesystems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Embodiments are directed to file systems. A replication engine may establish a secure communication channel between a source file system and a target file system. The replication engine may: instantiate a replication job associated with rules, determine changes in the source file system, determine characteristics of the replication job that may be based on the changes, compare the to the characteristics and a black-out schedule, execute the replication job to communicate the changes in the source file system to the target file system based on a result of the comparison. Upon completion of the replication job, the replication engine may automatically instantiating a next replication job to copy subsequent changes in the source file system to the target file system.”

The patent application was filed on September 7, 2018 (16/125,573).
