Publication number: 20240028519Abstract: Techniques for data processing involve: performing, according to a determination that a programmable circuit receives user-written data, data feature detection by the programmable circuit on a first part of the user-written data. Such techniques further involve: replacing, in response to the first part matching a predetermined data feature, the first part by the programmable circuit with a data representation corresponding to the predetermined data feature. In addition, such techniques involve: writing the data representation to a cache region of a storage system. Accordingly, such techniques can save cache resources of a storage system and can save CPU of the storage system, thus avoiding the latency due to data feature detection and improving the user experience.Type: ApplicationFiled: February 7, 2023Publication date: January 25, 2024Inventors: Weibing Zhang, Lei Gao, Donglei Wang, Shuning Zhang, Jianping Song

Publication number: 20230407441Abstract: The present disclosure relates to an alloy wire rod and a preparation method and application thereof. The alloy wire rod is made of a tungsten alloy, and the tungsten alloy contains tungsten and an oxide of cerium. The alloy wire rod has a wire diameter of equal to or less than 100 ?m; and the alloy wire rod has a tensile strength of greater than 3,800 MPa. The wire diameter of the alloy wire rod is equal to or less than 60 ?m; the diameter of a push-pull core wire of the alloy wire rod is less than 350 ?m; the elastic ultimate strength of the alloy wire rod is greater than 2,500 MPa; and the tensile strength of the alloy wire is greater than 4,200 MPa. In the present disclosure, the alloy wire rod having ultra-high strength and good toughness is obtained by doping an oxide of cerium.Type: ApplicationFiled: December 15, 2021Publication date: December 21, 2023Inventors: Minfeng TANG, Fusheng PENG, Donghong GUO, Yijin FANG, Sheng LV, Tongkai YAO, Xianyue WU, Weibing ZHANG, Qijian TU

Publication number: 20230125833Abstract: A method of performing synchronous replication from a primary storage system apparatus (PSSA) to a secondary storage system apparatus (SSSA) is provided. The method includes (a) in response to write requests received by the PSSA, (i) calculating metadata changes by the PSSA for accommodating the write requests, (ii) generating, by the PSSA, metadata journal log entries that describe the metadata changes, and (iii) mirroring the metadata journal log entries from the PSSA to the SSSA; (b) regenerating the metadata changes by the SSSA based on the metadata journal log entries mirrored from the PSSA to the SSSA; and (c) writing the regenerated metadata changes to persistent storage of the SSSA. A method performed by the SSSA is also provided. An apparatus, system, and computer program product for performing similar methods are also provided.Type: ApplicationFiled: October 26, 2021Publication date: April 27, 2023Inventors: Joseph Yuan Gu, Tianfang Xiong, Qi Qu, Weibing Zhang, Lei Gao, Wai C.
