    摘要: Embodiments of the present invention provide a memory data migration method and apparatus, and a computer, to migrate memory data that is in the computer. After acquiring a first trigger instruction, an operating system of the computer can suspend a task that is being executed, to execute memory data migration, determine a source memory card of to-be-migrated memory data, determine a backup memory card for the source memory card, and instruct a memory controller of the source memory card to perform the memory data migration, so that the memory controller of the source memory card reads memory data of the source memory card according to an instruction of the operating system, and writes the read memory data of the source memory card into the backup memory card. Therefore, the memory data of the source memory card can be migrated without powering off of the computer, thereby implementing online maintenance on a faulty memory card and resolving a problem in the prior art that a faulty memory card can be replaced or maintained only after an entire computer is powered off.

    摘要: The storage devices of a storage device set (e.g., a RAID array) may generate a nonvolatile representation of the configuration of the storage device set, including logical disks, spaces, storage pools, and layout and provisioning plans, on the physical media of the storage devices. A computer accessing the storage device set may also generate volatile memory representation of the storage device set to use while accessing the storage devices; however, the nonvolatile representation may not be performant due to its different usage and characteristics. Presented herein are techniques for accessing the storage device set according to volatile memory representation comprising a hierarchy of logical disks, slabs, and extents, and an accessor comprising a provisioning component that handles slab accesses while applying provisioning plans, and that interfaces with a lower-level layout component that translates slab accesses into storage device accesses while applying layout plans to the storage device set.

    摘要: If the first storage apparatus is suspended, it is determined which of the update number which the journal recently reflected in the second storage apparatus comprises and the update number which the journal recently reflected in the third storage apparatus comprises is the newer. It is determined, in the newer storage apparatus which is determined to comprise the newer update number, whether one or more differential journals from the journal comprising the update number next to the update number which is not determined to be the newer to the journal comprising the update number determined to be the newer exist or not. If the result of the determination is positive, from the newer storage apparatus to the previous storage apparatus which is not the newer of the second and the third storage apparatuses, one or more differential JNLs are copied. In the previous storage apparatus, one or more differential JNLs are reflected in order of the update numbers, to the data volumes in the previous storage apparatus.

    摘要: A system for displaying time-based events on a time line is described. A first timeline unit (1) displays a first timeline showing a first plurality of events within a first time segment (3) bounded by a first begin time and a first end time. A second timeline unit (2) displays a second timeline showing a second plurality of events within a second time segment (4) bounded by a second begin time and a second end time, wherein the first timeline and the second timeline are displayed in the same scale. An interaction unit (5) enables a user to indicate a change to the displayed time segments (3, 4). A time segment updater (6) determines an updated first time segment (3) and an updated second time segment (4) based on the indicated change, keeping the scale of the first timeline equal to the scale of the second timeline, and keeping an offset between the first time segment (3) and the second time segment (4) constant. The timeline units (1, 2) are arranged for updating their respective displays according to the updated time segments (3, 4).

    摘要: Embodiments of the present invention disclose a method and an apparatus for implementing protection of redundant array of independent disks in a file system, and are applied in the field of communications technologies. In the embodiments of the present invention, after receiving a file operation request, the file system needs to determine the type of a file to be operated as requested by the file operation request, and perform file operations in a hard disk drive of the file system directly according to a file operation method corresponding to the determined file type, that is, a redundant array of independent disks RAID data protection method. Therefore, corresponding file operations may be performed in a proper operation method according to each different file types, and data of an important file type is primarily protected, thereby improving reliability of data storage.
