Vast Data Assigned Two Patents

Snapshot capacity estimation
Vast Data Ltd., Tel Aviv, Israel, has been assigned a patent (11789900) developed by Weissman, Asaf, Zdornov, Vlad, Goren, Avi, and Shamir, Ohad, Tel Aviv, Israel, for a “snapshot capacity estimation.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for determining size information related one or more snapshots related to file systems stored in a storage system, the method may include (a) sampling one or more combinations of points in time and logical spaces, the logical spaces are associated with the one or more file systems to provide sampled combinations of sampled portions of file system entities (FSEs) and sampled points in time, (b) searching for relevant snapshots that are relevant to the sampled combinations to provide relevant snapshots at the sampled points in time, and (c) determining physical sizes of the relevant snapshots at the sampled point in time, wherein a number of samples per sampled FSE is indicative of a size of the sampled FSEs.”

The patent application was filed on 2022-03-30 (17/657339).

Lock metadata re-balancing upon storage expansion
Vast Data Ltd., Tel Aviv, Israel, has been assigned a patent (11789924) developed by Yelin, Ido, Goren, Avi, and Sonin, Oded, Tel Aviv, Israel, for a “lock metadata re-balancing upon storage expansion.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for lock metadata re-balancing upon an expansion of a storage system, the method may include instructing multiple compute entities, by an expansion manager and during a first phase of the lock metadata re-balancing, to acquire locks by using: (a) a current translation function for linking addresses of current lock metadata units (LMUs) to identifiers of stored entities, wherein the current translation function is based on a size of a current storage space allocated to the lock metadata, and (b) a next translation function for linking addresses of new LMUs to identifiers of stored entities, wherein the new translation function is based on a size of a new storage space allocated to the lock metadata, wherein the current space is expanded during the expansion of the storage system to provide the next storage space. Instructing the multiple compute entities, by the expansion manager, and during another phase of the lock metadata re-balancing that follows a release of all current LMUs, to acquire locks and check status of locks using the next translation function without using the current translation function.”

The patent application was filed on 2021-10-14 (17/450991).
