摘要： A storage cluster is provided. The storage cluster includes a plurality of storage nodes within a single chassis. Each of the plurality of storage nodes has nonvolatile solid-state memory for storage of user data. The plurality of storage nodes are configured to distribute the user data and metadata throughout the plurality of storage nodes with erasure coding of the user data such that the plurality of storage nodes can access the user data, via the erasure coding, with a failure of two of the plurality of storage nodes. The plurality of storage nodes are configured to employ the erasure coding to reconfigure redundancy of the user data responsive to one of adding or removing a storage node.

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： An example method involves receiving, at a first memory node, data to be written at a memory location in the first memory node. The data is received from a device. At the first memory node, old data is read from the memory location, without sending the old data to the device. The data is written to the memory location. The data and the old data are sent from the first memory node to a second memory node to store parity information in the second memory node without the device determining the parity information. The parity information is based on the data stored in the first memory node.

摘要： A data storage device may comprise a flash controller and an array of flash memory devices coupled to the flash controller. The array may comprise a plurality of S-Pages that may each comprise a plurality of F-Pages. In turn, each of the plurality of F-Pages may be configured to store a variable amount of data and a variable amount of error correction code. The flash controller may be configured to generate an error correction code across each F-Page of an S-Page and to store the generated error correction code within one or more F-Pages having the largest amount of data.

摘要： A computing system can include a processor and a persistent main memory including a fault tolerance capability. The computing system can also include a memory controller to store data in the persistent main memory and create redundant data. The memory controller can also store the redundant data remotely with respect to the persistent main memory. The memory controller can further access the redundant data during failure of the persistent main memory.

摘要： Technology is disclosed for performing background initialization on protection information enabled storage volumes or drives. In some embodiments, a storage controller generates multiple I/O requests for stripe segments of each drive (e.g., disk) of multiple drives of a RAID-based system (e.g., RAID-based disk array). The I/O requests are then sorted for each of the drives according to a pre-determined arrangement and initiated in parallel to the disks while enforcing the pre-determined arrangement. Sorting and issuing the I/O requests in the manner described herein can, for example, reduce drive head movement resulting in faster storage subsystem initialization.
