Adaptive storage management for optimizing multi-tier data storage system
Quantum Corporation, San Jose, CA, has been assigned a patent (9,965,389) developed by Doerner, Don, San Jose, CA, for an “adaptive storage management for optimizing multi-tier data storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Embodiments provide adaptive storage management for optimizing multi-tier data storage. A storage manager may interact with storage decision advisors. The manager may adaptively make storage management decisions, (e.g., flush, evict, recall, delete) after considering recommendations from and the credibility of the storage decision advisors. The manager may update the credibility of storage decision advisors based on how their recommendations affected optimization. The manager may adaptively choose when to rebalance or reconfigure the credibility of the storage decision advisors. Storage decision advisors may themselves be adaptive. Storage decision advisors may examine credibility feedback from the storage manager to determine which recommendations were useful and which were not. Storage decision advisors may then change when they will make a recommendation, when they will abstain from making a recommendation, the type of recommendation provided, or other behavior. Optimization may concern performance, cost, power usage, or other factors.”

The patent application was filed on September 1, 2015 (14/841,788).

Power savings in cold storage
Quantum Corporation, San Jose, CA, has been assigned a patent (9,965,351) developed by Arslan, Suayb, Irvine, CA, and Goker, Turguy, Vista, CA, for a “power savings in cold storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Methods and apparatus associated with data cold storage are described. Example apparatus include an array of data storage devices arranged in rows and columns. Columns of the array are orthogonal to rows. A row has an associated row-centric power supply, and a column has an associated column-centric local electronics module, (LEM) that controls a data storage device in the column independently of other data storage devices in the array. Example apparatus include logics that control a power mode of a data storage device independently of other data storage devices in the array, that control a power mode of an LEM, that adaptively regulate the level of data stored in a buffer, and that determine whether a data object will be stored in the buffer or stored on a data storage device in the array, based on the probability the data object will be accessed within a threshold period of time.”

The patent application was filed on January 21, 2016 (15/002,560).

Providing file system viewing of storage environment
Quantum Corporation, San Jose, CA, has been assigned a patent (9,959,131) developed by Wade, Gregory L., San Jose, CA, and Haile, J. Mitchell, Somerville, MA, for “systems and methods for providing a file system viewing of a storage environment.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data identification system and method for operating the data identification system are provided. The method comprises identifying processing elements contained within the storage environment, identifying virtual processing elements contained within the processing elements, identifying virtual storage elements contained within the virtual processing elements, identifying contents of the virtual storage elements, generating the file system view of the storage environment, wherein the file system view comprises the processing elements, the virtual processing elements, the virtual storage elements, and the contents of the virtual storage elements arranged in a hierarchical order. The file system view of the storage environment is then provided.”

The patent application was filed on August 2, 2010 (12/849,006).

Single pass file system repair with copy on write
Quantum Corporation, San Jose, CA, has been assigned a patent (9,898,468) developed by Preslan, Ken, Minneapolis, MN, and Lord, Stephen, Prior Lake, MN, for a “single pass file system repair with copy on write.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Example apparatus and methods concern identifying an error in a file system. The error is identified during one or more b-tree traversals through the file system. A fix for the error is produced upon detecting the error. Data or metadata associated with the fix is not initially written to the file system, but instead is stored somewhere other than the file system using a copy on write approach. After the traversals are complete, the file system may be fixed using the data or metadata stored using the copy on write approach.”

The patent application was filed on December 18, 2013 (14/132,324).

Vectored data de-duplication
Quantum Corporation, San Jose, CA, has been assigned a patent (9,886,470) developed by Saliba, George, and White, Theron, Boulder, CO, for “methods and systems for vectored data de-duplication.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present invention is directed toward methods and systems for data de-duplication. More particularly, in various embodiments, the present invention provides systems and methods for data de-duplication that may utilize a vectoring method for data de-duplication wherein a stream of data is divided into ‘data sets’ or blocks. For each block, a code, such as a hash or cyclic redundancy code may be calculated and stored. The first block of the set may be written normally and its address and hash can be stored and noted. Subsequent block hashes may be compared with previously written block hashes.”

The patent application was filed on March 10, 2015 (14/642,988).

Messaging policy controlled email de-duplication
Quantum Corporation, San Jose, CA, has been assigned a patent (9,876,746) developed by Wideman, Roderick B., Shakopee, MN, for a “messaging policy controlled email de-duplication.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Example methods and apparatus associated with a messaging policy controlled email deduplication are provided. In one example a messaging policy is accessed. It is determined whether a received message complies with the policy based on rules of the messaging policy. If a message complies with the messaging policy, the message is displayed. If the message does not comply with the messaging policy, it is determined whether the message is duplicative. If the message is deemed duplicative it is not displayed. Conversely, if the message is not deemed duplicative it is displayed.”

The patent application was filed on October 16, 2014 (14/515,705).

Vectored data de-duplication
Quantum Corporation, San Jose, CA, has been assigned a patent (9,875,271) developed by Saliba, George, and White, Theron, Boulder, CO, for “methods and system for vectored data de-duplication.“

Log structured block device for hard disk drive
Quantum Corporation, San Jose, CA, has been assigned a patent (9,851,926) developed by Doerner, Don, San Jose, CA, for a “log structured block device for hard disk drive.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Example apparatus and methods provide a log structured block device for a hard disk drive, (HDD). Data that is to be stored on an HDD is serialized and written as a series of data blocks using a sequential write. Information about where individual data blocks were supposed to be written, (e.g., actual address), neighboring data blocks, where data blocks were actually written, and how often data blocks are accessed is maintained. During garbage collection, data blocks that are being accessed with similar frequencies may be relocated together, with the most frequently accessed, (e.g., hottest) data blocks migrating to the outer cylinders of the disk and the least frequently accessed, (e.g., coldest) data blocks migrating to the inner cylinders. Blocks stored in the same temperature regions that were intended to be located together when written may be repositioned to facilitate sequential reads.”

The patent application was filed on June 2, 2015 (14/728,038).
