Vast Data Assigned Three Patents

Data recovery in storage
Vast Data Ltd., Tel Aviv, Israel, has been assigned a patent (11734117) developed by Vaknin, Yogev, Klipper, Lior, and Berger, Alon, Tel Aviv, Israel, for a “data recovery in a storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for recovering failed chunks, the method may include (i) obtaining a failure indication about a failure of a first number (X1) of failed chunks, wherein the chunks were stored in a group of disks, the group of disks is configured to store a second number (α) stripes of multiple (N) chunks, wherein each stripe comprises a first plurality (K) of data chunks and a second plurality (R) of parity chunks, wherein R exceeds ( X ⁢ 1 α ), and (ii) performing at least one recovery iteration until fulfilling a stop condition. Each recovery iteration of the at least one recovery iteration may include (a.i) selecting valid chunks to provide selected valid chunks, wherein a number of selected chunks is smaller than a product of a multiplication of R by α, (a.ii) retrieving valid data chunks that are relevant to the selected valid chunks, and (a.iii) attempting to reconstruct the failed chunks based on the retrieved chunks.”

The patent application was filed on 2021-04-29 (17/302318).

Hierarchical workload allocation in a storage system
Vast Data Ltd., Tel Aviv, Israel, has been assigned a patent (11726827) developed by Goren, Avi, Vaknin, Yogev, Levy, Asaf, and Sonin, Oded, Tel Aviv, Israel, for a “hierarchical workload allocation in a storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for hierarchical workload allocation in a storage system, the method may include determining to reallocate a compute workload of a current compute core of the storage system, wherein the current compute core is responsible for executing a workload allocation unit that comprises one or more first type shards, and reallocating the compute workload by (a) maintaining the responsibility of the current compute core for executing the workload allocation unit, and (b) reallocating at least one first type shard of the one or more first type shards to a new workload allocation unit that is allocated to a new compute core of new compute cores.”

The patent application was filed on 2021-03-02 (17/249463).

Maintaining availability of storage system
Vast Data Ltd., Tel Aviv, Israel, has been assigned a patent (11726662) developed by Goren, Avi, Miron, Amir, Yellin, Ido, and Levy, Asaf, Tel Aviv, Israel, for “maintaining an availability of a storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for maintaining an availability of a storage system, the method may include obtaining, by a control module of the storage system, problem related information generated by one or more compute nodes of the storage system, the problem related information is indicative of one or more problems associated with an execution of one or more storage operations, determining, by the control module and based on the problem related information, whether to forbid an execution of a storage operation of the one of more storage operations, and updating, by the control module, and based on the determining, a forbidden storage operation data structure that is accessible to the compute nodes of the storage system.”
