WekaIO has been assigned patents (10545669) for "congestion mitigation in a distributed storage system," and (10545921) for "metadata control in a load-balanced distributed storage system," and has 41 more patents pending.

The abstract of the patent (10545669) published by the U.S. Patent and Trademark Office states: A system comprises a plurality of computing devices that are communicatively coupled via a network and have a file system distributed among them, and comprises one or more file system request buffers residing on one or more of the plurality of computing devices. File system choking management circuitry that resides on one or more of the plurality of computing devices is operable to separately control: a first rate at which a first type of file system requests (e.g., one of data requests, data read requests, data write requests, metadata requests, metadata read requests, and metadata write requests) are fetched from the one or more buffers, and a second rate at which a second type of file system requests (e.g., another of data requests, data read requests, data write requests, metadata requests, metadata read requests, and metadata write requests) are fetched from the one or more buffers.

The patent (10545669) application was filed on March 15, 2019 (16/355,126).

The abstract of the patent (10545921) published by the U.S. Patent and Trademark Office states: A plurality of computing devices are communicatively coupled to each other via a network, and each of the plurality of computing devices is operably coupled to one or more of a plurality of storage devices. A plurality of failure resilient address spaces are distributed across the plurality of storage devices such that each of the plurality of failure resilient address spaces spans a plurality of the storage devices. The plurality of computing devices maintains metadata that maps each failure resilient address space to one of the plurality of computing devices. The metadata is grouped into buckets. Each bucket is stored in a group of computing devices. However, only the leader of the group is able to directly access a particular bucket at any given time.

The patent (10545921) application was filed on August 7, 2017 (15/670,189).
