Huawei Assigned Two Patents

Block storage-based data processing
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (9,507,720) developed by Yu, Qiang, and Wang, Daohui, Shenzhen, China , for a “block storage-based data processing methods, apparatus, and systems.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present disclosure relates to the field of information technology, and in particular, to a block storage-based data processing method, apparatus, and system. The block storage-based data processing method provided in embodiments of the present disclosure is applied in a system including at least two storage nodes, each storage node including a CPU, a cache medium, and a non-volatile storage medium, and the cache medium in all the storage nodes forming a cache pool. According to the method, after receiving a data operation request sent by a client, a service processing node sends the data operation request to a corresponding storage node in the system according to a logical address carried in the data operation request, so that the data operation request is processed in the cache medium of the storage node under control of the CPU of the storage node.“

The patent application was filed on December 30, 2013 (14/143,186).

Generating and recovering memory snapshot of virtual machine
Huawei Technologies Co., Ltd., Shenzhen, China, has been assigned a patent (9,507,672) developed by Ye, Chuan, Hangzhou, China, for a “method, apparatus, and system for generating and recovering memory snapshot of virtual machine.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for generating and recovering a memory snapshot of a virtual machine is provided. The method includes: obtaining a current S.sup.th memory page of the virtual machine, identifying a page type of the current S.sup.th memory page, where the page type includes an invalid data page and a valid data page, and recording the page type of the current S.sup.th memory page in a memory snapshot file when the page is an invalid data page, and recording the page type and page data of the current S.sup.th memory page in the memory snapshot file when the page is a valid data page, so that only valid data is stored according to the embodiments of the present invention, thereby reducing backup of invalid data, greatly shortening the generation time of the memory snapshot, reducing the size of the memory snapshot file, and saving storage resources.“

The patent application was filed on April 14, 2014 (14/251,785).
