Futurewei Technologies Assigned Five Patents

Generating parity for storage device
Futurewei Technologies, Inc., Plano, TX, has been assigned a patent (10,169,142) developed by Tang, Xiangyu, Canada, and Wu, Yunxiang, Cupertino, CA , for a “generating parity for storage device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method is performed by a solid state device, (SSD) controller to generate a parity. The method includes receiving input data to be stored to pages of a storage device, wherein each page is capable of being allocated with multiple codewords, configuring codewords of the pages into multiple groups, wherein each group has an integer number of codewords, at least one of the pages is allocated with a non-integer number of codewords, and wherein the integer number is larger than the non-integer number, obtaining parities for the multiple groups, and storing the parities to reserved spaces of the storage device. With the calculation of a parity decoupled from physical pages, the selection of a rate of code used is unconstrained by an integer number of codewords per page.“

The patent application was filed on July 12, 2016 (15/208,583).

Cross-controller request handling in active/active storage systems
Futurewei Technologies, Inc., Plano, TX, has been assigned a patent (10,162,775) developed by Kampe, Mark, Los Angeles, CA, Chen, Can, Chengdu, CN, Liu, Jinshui, Frisco, TX, and Zhang, Wei, Shenzhen, China, for “system and method for efficient cross-controller request handling in active/active storage systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system and method for cross-controller data storage operations comprises interconnecting a responding storage controller and an owning storage controller with a direct memory access, (DMA) capable fabric, the responding storage controller and the owning storage controller each comprising an interface from a data bus connected to the DMA capable fabric, configuring and implementing a shared DMA address space in accordance with the DMA capable fabric, the shared DMA address space including memory on the responding storage controller and the owning storage controller, the shared DMA address space being one of a symmetric or asymmetric address space, and exposing one or more local buffers of the responding storage controller and one or more local buffers of the owning storage controller through the shared DMA address space.“

The patent application was filed on December 22, 2015 (14/979,264).

Data protection for cold storage
Futurewei Technologies, Inc., Plano, TX, has been assigned a patent (10,152,378) developed by Zhu, Xiaogang, and Mortazavi, Masood, Santa Clara, CA, for a “data protection for a cold storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A cold storage system includes data storage devices and parity storage devices. The data storage devices and the parity storage devices form a multiple dimensional matrix which has multiple rows and multiple columns. A controller receives a data write request, selects a data storage device for storing a plurality of data blocks, and writes the data blocks sequentially into memory blocks of the selected data storage device, each data block belonging to a row stripe distributed over one row of the matrix and to a column stripe distributed over one column of the matrix. The controller also generates a row protection block for the row stripe and a column protection block for the column stripe, and writes the row protection block and the column protection block to parity storage devices in the system.“

The patent application was filed on October 4, 2016 (15/285,128).

Application driven and adaptive unified resource management for data centers
with multi-resource schedulable unit
Futurewei Technologies, Inc., Plano, TX, has been assigned a patent (10,129,101) developed by Luo, Min, San Jose, CA, Estevez, David, San Francisco, CA, and Zhu, Jiafeng, San Ramon, CA, for an “application driven and adaptive unified resource management for data centers with Multi-Resource Schedulable Unit, (MRSU).“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An apparatus comprising a processor configured to obtain estimated processing requirements, estimated memory requirements, estimated storage requirements, and estimated network communication requirements for a plurality of data center, (DC) tenants, determine a Minimum Resource Schedulable Unit, (MRSU) for the tenants, the determined MRSU comprising a dynamically allocatable group of processor resources, processing memory resources, storage resources, and network resources comprised in at least one of a plurality of DC servers, wherein the MRSU is determined such that each DC tenant’s estimated processing requirements, estimated memory requirements, estimated storage requirements, and estimated network communications requirements are met by allocation of a corresponding integer value of MRSUs, and allocate the corresponding integer value of MRSUs to each DC tenant as an MRSU allocation, and a transmitter coupled to the processor and configured to transmit the MRSU allocation to the DC servers for allocation to the DC tenants.“

The patent application was filed on April 19, 2016 (15/132,443).

SSD storage access
Futurewei Technologies, Inc., Plano, TX, has been assigned a patent (10,089,017) developed by Huang, Yiren, San Jose, CA, Wang, Yong, Sunnyvale, CA, and Lin, Kui, Redwood City, CA, for “method and apparatus for SSD storage access.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A media management system including an application layer, a system layer, and a solid state drive, (SSD) storage layer. The application layer includes a media data analytics application configured to assign a classification code to a data file. The system layer is in communication with the application layer. The system layer includes a file system configured to issue a write command to a SSD controller. The write command includes the classification code of the data file. The SSD storage layer includes the SSD controller and erasable blocks. The SSD controller is configured to write the data file to one of the erasable blocks based on the classification code of the data file in the write command. In an embodiment, the SSD controller is configured to write the data file to one of the erasable blocks storing other data files also having the classification code.“

The patent application was filed on May 22, 2012 (13/477,924).
