  • Patent number: 10445372
    Abstract: A method includes accessing, in response to initiating an operation targeting data, auxiliary mapping data to determine whether the auxiliary mapping data includes an indication of a key associated with a node of a hierarchical data structure that is associated with the data. In response to the auxiliary mapping data including the indication of the key, the data is accessed from a memory using a node identification associated with the key. In response to the auxiliary mapping data not including the indication of the key, the data is accessed from the memory using a search operation.
    Type: Grant
    Filed: February 1, 2016
    Date of Patent: October 15, 2019
    Assignee: SanDisk Technologies LLC.

  • Publication number: 20170123971
    Abstract: Systems, methods, and/or devices are used to store metadata in a storage system. In one aspect, a first user space module sends a logical memory request to a memory management module of a kernel space module. The logical memory request includes data and metadata. A second user space module obtains the metadata of the logical memory request. A storage engine of the second user space module determines, in accordance with the obtained metadata, a location in non-volatile memory for the data. A second user space module generates a physical memory request including an indication of the non-volatile memory for the data. The second user space module transmits the physical memory request to the kernel space memory management module.

  • Publication number: 20150261465
    Abstract: A method of storing data to an aggregate storage system including: receiving data at the aggregate storage system, wherein the aggregate storage system includes a random-access storage component and a sequential-access storage component, and wherein the data includes one or more data portions and one or more metadata portions; identifying each portion of the data as either one of the data portions or one of the metadata portions; in response to determining that one of the metadata portions is identified, writing the metadata portion to the random-access storage component and the sequential-access storage component; and in response to determining that one of the data portions is identified, writing the data portion only to the sequential-access storage component.
