Patent number: 11003558Abstract: A method of resilvering a plurality of failed devices in storage pools includes detecting a failure of a first storage device in a storage pool, identifying data blocks that were stored on the first storage device that are also stored on other storage devices, and resilvering the first storage device by transferring the data blocks from the other storage devices. While resilvering the first storage device, the method includes detecting a failure of a second storage device in the storage pool, identifying a subset of the data blocks that were stored on the first storage device that were also stored on the second storage device, and reusing a set of sequential I/O commands to resilver at least a portion of the second storage device with the subset of the data blocks.Type: GrantFiled: May 27, 2020Date of Patent: May 11, 2021Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Eric Carl Taylor, Zhu Xiao

Patent number: 10671501Abstract: A method of reconstructing data from a failed storage device in a storage pool includes identifying a plurality of data blocks that are stored on the failed storage device, and sorting the plurality of data blocks in an order in which the plurality of data blocks are located on the failed storage device. Each of the plurality of data blocks may be associated with an I/O operation. The method may also include grouping the I/O operations for the plurality of data blocks into sequential I/O operations based on the order in which the plurality of data blocks are located on the failed storage device, and executing the sequential I/O operations to resilver a new storage device replacing the failed storage device.Type: GrantFiled: May 31, 2017Date of Patent: June 2, 2020Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Eric Carl Taylor, Zhu Xiao

Patent number: 10671500Abstract: A method of resilvering a plurality of failed devices in a storage pool may include detecting a failure of a first storage device in the storage pool, and determining a plurality of data blocks that are stored on the first storage device. The method may also include sorting the plurality of data blocks into one or more buckets in an order in which the plurality of data blocks are located on the first storage device, and detecting a failure of a second storage device in the storage pool after detecting the failure of the first storage device. The method may further include determining that one or more of the plurality of data blocks are also located on the second storage device, and reusing at least part of the one or more buckets to resilver the second storage device.Type: GrantFiled: January 17, 2017Date of Patent: June 2, 2020Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Eric Carl Taylor, Zhu Xiao

Publication number: 20160015001Abstract: A recombinant dog chews from animal skin forming technique is disclosed. The process comprising the steps of: granulate the scrap skin materials. After cortical granulate, the piece size is 0.5 mm-20 mm; put the skin particulates into clean water and soak, the soaking time is not less than 2 h; 3) After soaking, the cortical granules were melted at a pre-set temperature. Forming a gel and extruded to form a whole piece skin. Through this process the recombinant animal skins become homogeneous structure, there is no grainy after this process, the product quality was enhanced. Since we do not add any kind of binder such as gelatin, a recombinant hide has a very excellent flexibility, the toughness was almost the same, thus it's easier to tie a knot during the manufacturing process later on.Type: ApplicationFiled: July 14, 2015Publication date: January 21, 2016Applicant: WENZHOU YUANFEI PET TOY PRODUCTS CO., LTDInventors: Zhuang Ming Yun, Zhu Xiao Rong
