摘要： According to one embodiment, an information processing system includes a host (2) and memory systems (3). A first memory system stores first data in a nonvolatile memory (5). A second memory system stores second data in a nonvolatile memory (5). The host (2) transmits first update data to the first memory system and transmits second update data to the second memory system. The first memory system generates first XOR data by performing an XOR operation on at least the first data and the first update data, and transmits the first XOR data to the second memory system. The second memory system generates second XOR data by performing an XOR operation on the second data, the second update data, and the first XOR data, and transmits the second XOR data to a third memory system.

摘要： A method for processing a stripe in a storage device and a storage device are provided. The method includes: determining at least two stripes in the storage device that satisfy a garbage collection condition, where each of the at least two stripes includes a stripe unit requiring garbage collection and a stripe unit not requiring garbage collection; determining at least one stripe unit not requiring garbage collection from each stripe; computing parity data of data in the determined stripe units not requiring garbage collection; and storing the parity data into a first idle stripe unit, where the first stripe unit and the determined stripe units not requiring garbage collection are constructed into a new stripe in the storage device. In a scenario of performing garbage collection on a stripe, according to the method, a data migration amount can be effectively reduced, thereby reducing write operations on the storage device, and lowering performance overheads of the storage device.

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： A memory module comprises a volatile memory subsystem configured to coupled to a memory channel in computer system and capable of serving as main memory for the computer system, a non- volatile memory subsystem providing storage for the computer system, and a module controller coupled to the volatile memory subsystem, the non- volatile memory subsystem, and the C/A bus. The module controller is configured to control intra- module data transfers between the volatile memory subsystem and the non- volatile memory subsystem. The module controller is further configured to monitor C/A signals on the C/A bus and schedule the intra-module data transfers in accordance with the C/A signals so that the intra-module data transfers do not conflict with accesses to the volatile memory subsystem by the memory controller.

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： In a memory system where memory units may be separated from each other so as to operate substantially independently, the coordination of related memory operations between such units may be by synchronization of an epoch of time and the start of an epoch of time with a common synchronization source. The source may be distributed directly to each of the memory modules of a memory unit, or through an intermediate synchronization circuit of a memory unit that is common to the modules. Where the data is stored as a RAID stripe on a plurality of synchronized modules, the read and write or erase operations performed by the modules may be arranged such that the write operations or erase operations may not substantially affect the ability to promptly read the stored data of a RAID stripe.
