The abstract of the patent published by the U.S. Patent and Trademark Office states: “Mass storage is allocated to a logical server. The logical server is deployed to a real server.“

The patent application was filed on March 17, 2009 (12/406,059).

Direct attached storage for implementing multiple simultaneous storage schemes
Hewlett Packard Enterprise Development LP, Houston, TX, has been assigned a patent (9,542,116) developed by Thomas, Fred Charles, Walker, Phillip M., Fort Collins, CO, and Lipinski, Greg J., Loveland, CO, for a “direct attached storage system and method for implementing multiple simultaneous storage schemes.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A direct attached storage, (DAS) system configurable to simultaneously implement a plurality of data storage schemes, comprising one or more storage devices, a controller coupled to the storage devices for implementing and managing a plurality of data storage schemes on the storage devices, an I/O port for inputting data to and outputting data from the storage devices, and an apportionment selector coupled to the controller for selecting a portion of the storage devices to be allocated to a determined data storage scheme.“

The patent application was filed on October 23, 2008 (13/054,610).

Query summary generation using row-column data storage
Hewlett Packard Enterprise Development LP, Houston, TX, has been assigned a patent (9,535,961) developed by Dash, Debabrata, Vaud, Switzerland, Tang, Wenting, Sunnyvale, CA, Orayani, Marylou, San Jose, CA, Cleveland, Bradley W., Los Altos, CA, and Utsumiya, Masaki, San Jose, CA, for a “query summary generation using row-column data storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage system includes a column store and a row store. The data storage system may generate a query summary. The data storage system determines query summary fields comprised of a subset of fields from a schema used to store data in the row store. The data storage system searches the column store or the row store for query results in the query summary fields. A query summary field is generated from the query results in the query summary fields.“

The patent application was filed on November 18, 2011 (14/358,500).

Non-volatile cache
Hewlett Packard Enterprise Development LP, Houston, TX, has been assigned a patent (9,535,835) developed by Russo, Leonard E., Tomball, TX, Gaspard, Walter A., Magnolia, TX, and Bellamy, Walter W., Spring, TX, for a “non-volatile cache.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for managing a storage device including determining whether the storage device includes a non-volatile cache, scanning for a clear cache instruction received from a computing machine, and clearing the non-volatile cache on the storage device in response to authenticating the clear cache instruction.“

The patent application was filed on April 12, 2010 (13/639,514).

Automatic WORM-retention state transitions
Hewlett Packard Enterprise Development LP, Houston, TX, has been assigned a patent (9,514,150) developed by Sparkes, Andrew M, Bristol, Great Britain, Kannan, Rajkumar, Bangalore, India, Spitzer, Michael J, Portland, OR, and Fernandes, Joseph E, Bangalore, India, for a “automatic WORM-retention state transitions.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Example embodiments relate to automatic WORM-retention state transitions. In example embodiments, a storage computing device may detect a request to access, via a file system, a file that is associated with a first retention state. The first retention state may indicate either a first type of WORM-retention protection for the file or no WORM-retention protection for the file. The storage computing device may determine, in response to the request, that the file should be designated with a second retention state. The second retention state may indicate a second type of WORM-retention protection for the file. The determination may be based on a retention policy file that is tightly integrated with the file system and metadata of the file. The storage computing device may transition the file, (e.g., by communicating with the file system) to be associated with the second retention state instead of the first retention state.“

The patent application was filed on April 19, 2013 (13/866,732).

Performance assist storage volumes
Hewlett Packard Enterprise Development LP, Houston, TX, has been assigned a patent (9,513,837) developed by Jenkins, Aaron L, Tomball, TX, Miller, Paul, Houston, TX, and Wu, Chiung-Sheng, The Woodlands, TX, for a “performance assist storage volumes.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques for allocation of storage volumes are described. Response times of a primary storage may be monitored to determine if the primary storage is input/output limited. A performance assist storage volume may be allocated and data replicated between the primary storage and the performance assist storage volume. Input/output requests may be distributed between the primary storage and the performance assist storage volume.“

The patent application was filed on October 12, 2011 (13/271,563).
