Nexenta Systems Assigned Patent

Nexenta Systems, Inc., Santa Clara, CA, has been assigned a patent (9,710,535) developed by Aizman, Alexander, Mountain View, CA, Bestler, Caitlin, Sunnyvale, CA, and Novak, Robert E., Tracy, CA, for a “object storage system with local transaction logs, a distributed namespace, and optimized support for user directories.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present invention relates to object storage systems that support hierarchical directories within a namespace manifest stored as an object. The namespace manifest is stored as namespace manifest shards that are determined based on a partial key derived from the full name of the referenced version manifest in each directory entry. Each storage server maintains a local transaction log that keeps track of changes to the namespace manifest in response to put transactions. The namespace manifest can be updated after each put transaction is acknowledged, which minimizes the number of write operations required for a put transaction. Updates to the namespace manifest are batched, distributed, and processed concurrently and in parallel by the storage servers that store the corresponding shards. This reduces the latency that would otherwise exist in the object storage cluster as a result of a put transaction. Updates to namespace manifest shards optionally occur in a batch process using MapReduce techniques.“

The patent application was filed on August 6, 2015 (14/820,471).
