[0077] FIG. 9 shows a conceptual diagram of a server 900 according to this embodiment. The second embodiment describes the mirroring mode.

[0078] [Conceptual Diagram of Server 900]

[0079] The server 900 includes: a system controller 901 , CPUs (Central Processing Units) 902 , 903 , 904 , and 905 , memory controllers 906 , 907 , 908 , and 909 , and memories 910 , 911 , 912 , and 913 . Server 900 runs in mirroring mode. The mirror mode is a mode in which the same data is stored in a pair of memories 910 and 911 and in a pair of memories 912 and 913 and the memories 910, 911, 912, and 913 are controlled synchronously. In this mode, data 916 and data 917 are data with the same description. Separate data block 918 stored in memory 910 and separate data block 920 stored in memory 912 are separate data blocks having the same description. Likewise, separate data block 919 stored in memory 911 and separate data block 921 stored in memory 913 are separate data blocks having the ...

Abstract

An information processing apparatus according to the present invention includes a controller for dividing data into a plurality of divided-data; a plurality of storage units for storing the plurality of divided-data, respectively; a plurality of storage controllers for writing the divided-data into the corresponding storage unit or reading out the divided-data from the respective storage units; a plurality of history storage units for storing histories of the operation of the corresponding storage controllers, respectively; an error detector for detecting an error in the divided-data; an error correction controller for controlling correction of the error; and a plurality of history controller for controlling update of the histories in the corresponding history storage units, respectively upon correction of the error.

Description

technical field [0001] The present invention relates to error analysis in an information processing device that can stop recording of processing history when an error occurs. Background technique [0002] An error may occur in a server that can perform synchronous processing for a memory controller that can allocate data to a plurality of memories and control the memories. The memory controller records the operation history of data processing and data to be processed in the history memory (hereinafter, a set of operation history and data is referred to as a log) as error analysis means. Then, when an error occurs, the faulty memory controller stops logging. Users of the server can analyze errors by referring to logs when errors occur. [0003] However, the errors analyzed using only the log in the faulty memory controller are limited to extremely simple errors, and not all errors can be analyzed at present. [0004] Performing a more detailed error analysis requires a log...
