摘要： A second core calculates an intervening variable v that is defined by an inner function g(x), when a time derivative dx/dt of a state variable x is expressed by a function f(x, g(x), u) having the state variable x, the inner function g(x), and an observable input variable u as independent variables. A first core calculates a function f(x, v, u) by using respective values of the state variable x, the intervening variable v, and the input variable u, and obtains a value of the state variable x by time-integration of a value of the function f(x, v, u). In the calculation of the function f(x, v, u), the value of the state variable x calculated in previous time, a value of the intervening variable v calculated by the second core in the previous time, and a value of the input variable u inputted in this time are used.

摘要： Embodiments of the present invention provide a method for writing data into a storage system and a storage system. The storage system includes a redundant array of independent disks (RAID). The RAID includes a control device and X storage devices, a data stripe stripe is stored in the RAID, and the stripe includes T members. The control device determines that at least one first storage device of the X storage devices is out of service, where at least one member is stored in the first storage device; selects a second storage device from the X storage devices, where a quantity of members stored in the second storage device is less than T/X; and then writes target data into the second storage device, where the target data is a data unit or a check unit used to update the at least one member that is stored in the first storage device. This can ensure data reliability to an extent.

摘要： A method for proactively rebuilding user data in a plurality of storage nodes of a storage cluster is provided. The method includes distributing user data and metadata throughout the plurality of storage nodes such that the plurality of storage nodes can read the user data, using erasure coding, despite loss of two of the storage nodes. The method includes determining that one of the storage nodes is unreachable and determining to rebuild the user data for the one of the storage nodes that is unreachable. The method includes reading the user data across a remainder of the plurality of storage nodes, using the erasure coding and writing the user data across the remainder of the plurality of storage nodes, using the erasure coding. A plurality of storage nodes within a single chassis that can proactively rebuild the user data stored within the storage nodes is also provided.

摘要： According to one embodiment, a memory system includes a nonvolatile memory (5) and a controller (4). The controller (4) manages a plurality of namespaces (NS #1 to NS #n) for storing a plurality of kinds of data having different update frequencies. The controller (5) encodes write data by using first coding for reducing wear of a memory cell to generate first encoded data, and generates second encoded data to be written to the nonvolatile memory (5) by adding an error correction code to the first encoded data. The controller (4) changes the ratio between the first encoded data and the error correction code based on the namespace to which the write data is to be written.

摘要： The present invention discloses a memory access apparatus for a message-type memory module, where the apparatus includes: a read-write module, configured to store, to a corresponding DRAM, an SCBC to be stored within a current read-write cycle; and a processing module, configured to: calculate one group of error detecting code for each SCBC in a memory row, and calculate one group of error correcting code for all SCBCs in a memory row; where the read-write module is further configured to: store the error detecting code in an (M+2) th DRAM in the memory row, and store the error correcting code in a Z th DRAM in the memory row, where Z is a positive integer, 1 ‰¤ Z ‰¤ (M+1), and error correcting codes in consecutive (M+1) memory rows are stored in different DRAMs. Embodiments of the present invention further provide a corresponding method. According to the technical solutions of the present invention, fine-granularity encoding protection is performed in a basic read-write unit of SCBC, and variable-granularity memory access is supported, so that error-correcting can be implemented for any multi-bit error in a single DRAM.

摘要： Mixed-granularity higher-level redundancy for NVM provides improved higher-level redundancy operation with better error recovery and/or reduced redundancy information overhead. For example, pages of the NVM that are less reliable, such as relatively more prone to errors, are operated in higher-level redundancy modes having relatively more error protection, at a cost of relatively more redundancy information. Concurrently, blocks of the NVM that are more reliable are operated in higher-level redundancy modes having relatively less error protection, at a cost of relatively less redundancy information. Compared to techniques that operate the entirety of the NVM in the higher-level redundancy modes having relatively less error protection, techniques described herein provide better error recovery. Compared to techniques that operate the entirety of the NVM in the higher-level redundancy modes having relatively more error protection, the techniques described herein provide reduced redundancy information overhead.
