QLogic Assigned Five Patents

Communication between computing system and device
QLogic, Corporation, Aliso Viejo, CA, has been assigned a patent (9,256,562) developed by Sarcar, Kanoj, Fremont, CA, and Thekkeettil, Madhusudhan Harigovindan, Bangalore, India, for a “method and system for communication between a computing system and a device.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Machine implemented method and system are provided. A processor for a computing device allocates an address range with an address to write to an intermediate storage location. The processor configures a device communicating with the computing device for writing information at the intermediate storage location and at a plurality of storage locations. The computing device sends the address for the intermediate storage location with data that needs to be written at one of the plurality of storage locations with an identifier identifying the one of the plurality of storage locations, and the device first writes the data at the intermediate storage location and then updates the one of the plurality of storage locations identified by the identifier.“

The patent application was filed on October 4, 2012 (13/644,535).

Data integrity
QLogic, Corporation, Aliso Viejo, CA, has been assigned a patent (9,256,491) developed by Dropps, Frank R., Maple Grove, MN, for a “method and system for data integrity.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A device having a storage location for receiving an original data and a corresponding original error correction code, (ECC) is provided. The device includes ECC modification pattern generator logic for comparing modified data and the original data for generating a pattern for modifying the original ECC and ECC modification logic for modifying the original ECC based on the pattern.“

The patent application was filed on September 23, 2013 (14/034,006).

Intelligent storage adapter used for both SAN and local storage access
QLogic, Corporation, Aliso Viejo, CA, has been assigned a patent (9,232,005) developed by Shah, Shishir, Irvine, CA, Singh, Ajmer, Rancho Santa Margarita, CA, Micalizzi, Jr., Charles, Capistrano Beach, CA, and Ponnachana, Sudhir T., Aliso Viejo, CA, for a “methods and systems for an intelligent storage adapter used for both SAN and local storage access.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An adapter for processing requests from a computing device is provided. The adapter includes a processor executing: a storage protocol driver for interfacing with a storage protocol controller that communicates with a storage device of a storage area network, (SAN) via a port for providing SAN connectivity to the adapter, and a storage driver for interfacing with a solid state storage device managed by the adapter and available to the computing device as a local caching device.“

The patent application was filed on March 8, 2013 (13/790,846).

High speed multiple buffer allocation
QLogic, Corporation, Aliso Viejo, CA, has been assigned a patent (9,229,791) developed by Thekkeettil, Madhusudhan Harigovindan, Bangalore, India, for a “system and method for high speed multiple buffer allocation.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”An adapter for high speed multiple buffer allocation is provided. The adapter is configured with logic to search a data buffer availability vector corresponding to data buffer storage elements from low priority to high priority and from high priority to low priority in parallel thereby enabling multiple data buffers to be located in a single path and reducing the impact of pipelining.“

The patent application was filed on August 24, 2012 (13/594,343).

Remote cache direct data placement
QLogic, Corporation, Aliso Viejo, CA, has been assigned a patent (9,223,518) developed by Emralino, Normin A., Huntington Beach, CA, for a “method and system for remote cache direct data placement.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Method and system for processing a read request are provided. The first adapter receives the read request from a client to read data using a logical object managed by a second adapter. The first adapter is configured to generate a vendor unique command descriptor block for the second adapter to obtain the data and write the data at a location specified by the read request. The second adapter is configured to retrieve the data from a storage location specified by the logical object and writing the data at the location specified by the read request, and notifies the first adapter after writing the data.“

The patent application was filed on November 22, 2013 (14/088,082).
