Hitachi Vantara Assigned Six Patents

Service plan tiering, protection, and rehydration strategies
Hitachi Vantara Corporation, Santa Clara, CA, has been assigned a patent (10,425,480) developed by Haapaoja, Steven, Boston, MA, Kats, Yury, Belmont, MA, Lee, Cody, Leominster, MA, and Isherwood, Benjamin, Tweksbury, MA, for “service plan tiering, protection, and rehydration strategies.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A storage system stores objects and copies of objects on the storage system and other storage systems external to the storage system. The storage system stores the copies in storage pools of volumes, which are organized into one or more tiers. The configuration settings of each tier and each pool within the tier may be configured according to a user’s preferences. In one example, the number of copies of data content and the number copies of metadata associated with the data content an individual pool stores may be specified. When objects are migrated between tiers, the objects are stored among the storage pools of the tiers. If the number of data content copies or metadata copies is increased, the data or metadata is copied from a determined copy source and if the number of copies decreases, the data is removed from the volumes in the pools.”

The patent application was filed on June 26, 2014 (14/316,319).

Metadata favored replication in active topologies
Hitachi Vantara Corporation, Santa Clara, CA, has been assigned a patent (10,387,449) developed by Isherwood, Benjamin, Tewksbury, MA, and Grimaldi, Kevin Canuette, Austin, TX, for a “metadata favored replication in active topologies.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method and apparatus for metadata favored replication in an active/active topology. When replicating data objects between multiple storage systems, metadata is sent first while the associated data content is sent at a subsequent time. Metadata is stored and made visible on a target storage system thereby reserving the object path in a namespace to reduce collisions in the namespace. After metadata is transferred to the target storage system, the target system performs collision processing to determine if an object already exists in the namespace prior to receiving the transferred metadata. After collision processing is performed, the winning object is made visible for access on the target storage system regardless of whether the associated data content has been transferred to the target system.”

The patent application was filed on May 30, 2014 (15/103,892).

Elastic metadata and multiple tray allocation
Hitachi Vantara Corporation, Santa Clara, CA, has been assigned a patent (10,372,537) developed by Bennett, Jr., Charles C., Carlisle, MA, Clark, Nathan W., Millbury, MA, Canuette Grimaldi, Kevin S., Watertown, MA, Maxwell, Morgan Tyler, Ashland, MA, Curry, Clayton A., Framingham, MA, and Cooper, Robert Barton, Somerville, MA, for “elastic metadata and multiple tray allocation.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”In some examples, both object data and corresponding metadata are stored on thin provisioned block storage in which blocks for the storage of the object data and the metadata are dynamically provisioned from a shared pool. For instance, the metadata may be stored on the block storage using a tree data structure that may grow proportionally with the corresponding stored object data. The object storage may automatically adapt to the size and number of objects being stored, and storage space for metadata may be allocated dynamically on demand. Additionally, some implementations include storing data across multiple trays. For instance, a plurality of storage extents of an extent group may be allocated across a plurality of storage devices on multiple trays. The extent allocation may be tray-aware by allocating extents to maximize the probability that data remains available/recoverable in the presence of a failure in one or more trays.”

The patent application was filed on October 7, 2015 (15/308,916).

Digital evidence management
Hitachi Vantara Corporation, Santa Clara, CA, has been assigned a patent (10,354,348) developed by Grbac, Arno, Santa Clara, CA, Avlani, Ankur, Sunnyvale, CA, Raghunathan, Sathish, and Mittal, Sumeet Kumar, Santa Clara, CA, for a “digital evidence management.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”In some examples, analysis metadata may be generated for received digital assets based on analysis of content of the digital assets. As one example, a service computing device may receive and store a digital asset and first metadata for the digital asset. The service computing device may determining a content category of content of the digital asset, and may analyze the content of the digital asset based at least in part on the content category to obtain at least one analysis result as additional metadata for the digital asset. The service computing device may store the analysis result in association with the digital asset and may store analysis metadata in association with the first metadata.”

The patent application was filed on May 17, 2016 (15/300,434).

Related computer-program for managing access request in multi-tenancy environments
Hitachi Vantara Corporation, Santa Clara, CA, has been assigned a patent (10,318,194) developed by Chittenden, Andrew Stephen, Reading, Great Britain, Smith, Jonathan Mark, Bracknell, Great Britain, Carlini, Antonio Robert, Abingdon, Great Britain, Payyanadan, Ashwin, Godalming, Great Britain, and Williams, Robert Ian, Reading, Great Britain, for “method and an apparatus, and related computer-program products, for managing access request in multi-tenancy environments.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The apparatus comprises a plurality of interfaces, each interface having an associated interface ID, and a hardware-side processing device including at least one programmable hardware-implemented chip configured to process request packets, which are received from host computers and relate to access requests to one or more file system managed by the apparatus, and to generate response packets for the processed request packets, wherein, for a request packet which is received from a first host computer, at least one programmable hardware-implemented chip is configured to: determine the client ID being associated with the first host computer, determine the interface ID being associated with the first interface, determine whether the determined client ID and interface ID represent a permitted ID set or a prohibited ID set, and refrain from processing the received request packet if the determined client ID and interface ID represent a prohibited ID set.”

The patent application was filed on October 2, 2014 (15/504,337).

Queue based object cloning
Hitachi Vantara Corporation, Santa Clara, CA, has been assigned a patent (10,311,152) developed by Berrington, Neil, and Ngo, Hoc D, San Jose, CA, for a “system for queue based object cloning.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A file cloning process allows for quickly cloning files within a filesystem, such as when a user makes a copy of a directory containing files and subdirectories of files. A priority based main queue is filled by a depth first traversal of the directory to be copied with work items corresponding to files and subdirectories. Worker threads refer to the main queue for file cloning, subdirectory copying and directory traversal. Files that have not been modified since a most recent checkpoint are cloned without issuing a checkpoint request. Files that have been modified since the most recent checkpoint are moved to a delay queue. Once a checkpoint of the file system completes, the files in the delay queue are then moved to the main queue to retry cloning thereof. A secondary queue is also provided to prevent worker threads from becoming deadlocked in the main queue.”

The patent application was filed on December 20, 2013 (15/105,196).
