Problems solved by technology

However, the failure rate of memory in the current system can be as high as 0.1%. Memory failure may not only cause the system to run unstable, but also cause the system to crash
[0004] The existing technology cannot realize the migration of memory data in the computer. When a memory failure occurs in the system, the migration of data in the faulty memory board or faulty memory stick cannot be realized when the computer is running normally, so online maintenance of the faulty memory cannot be performed. , the faulty memory board or faulty memory module can only be replaced after powering off the computer

specific Embodiment 1

[0113] combine figure 1 For the computer shown, the embodiment of the present invention provides a method for migrating memory data, such as image 3 As shown, it is used to migrate the memory data in the computer, for example, the memory data of the source memory card can be migrated to the backup memory card, and the source memory card is a memory card visible to the OS 103, that is, the OS 103 can perform read and write operations Memory card, that is, a memory card that may fail and need to migrate data, such as memory cards 101-A and 102-B in this embodiment, the backup memory card is a memory card that is invisible to OS 103, that is, OS 103 temporarily A memory card that cannot be read and written may be used as a target device for data to be migrated, such as the memory card 101-C in this embodiment. After the memory data is migrated, the configuration information of the backup memory card can be changed, such as It allocates system addresses so that OS 103 can perfor...

specific Embodiment 2

[0177] combine figure 1 For the computer shown, the embodiment of the present invention provides a method for migrating memory data, such as Figure 4 As shown, for migrating the memory data in the computer, for example, the memory data of the source memory card of the computer can be migrated to the backup memory card, the source memory card can be a memory card 101-A, and the backup memory card can be a memory card 101-C, the memory card 101-C can be a memory card that has been inserted into the hardware slot before the computer is turned on, or it can be a temporarily newly added memory card. Before performing memory data migration, the memory card 101-C The identification is configured in the ACPI list and the initialization process is completed before performing the migration. The method for migrating memory data in the embodiment of the present invention may include:

[0178] S401: The OS acquires and records the identifier of the designated backup memory card.

Abstract

The embodiment of the invention provides a migration method, a computer and a device of stored data, used for migrating the stored data in the computer. An operation system of the computer suspends current executed mission to execute the migration of the stored data after gaining a first trigger command, ensures a source memory card of the stored data to be migrated, ensures a back-up memory card for the source memory card, indicates a memory controller of the source memory card to perform the migration of the stored data to make the memory controller read the stored data in the source memory card according to the indication of the operation system, writing the stored data of the source memory card into the back-up memory card to migrate the stored data in the source memory card when the computer is out of power, thereby realizing online maintenance of the fault stored data and solving the problem that replacement and maintenance of the fault memory card can be performed only when the computer is out of power.

Description

technical field [0001] The invention relates to computer technology, in particular to a memory data migration method, computer and device. Background technique [0002] Memory (Memory), also known as main memory, is one of the most important components in a computer. All programs in the computer run in the memory, so the performance of the memory has a great impact on the computer. The memory can be used to temporarily store the calculation data in the processor, as well as the data exchanged with external storage such as hard disk. As long as the computer is running, the processor will transfer the data that needs to be calculated into the memory for calculation. After the calculation is completed, the processor will send the result out. The operation of the memory also determines the stable operation of the computer. [0003] Under the X86 architecture, the server supports more and more memory, the latest Intel E7 V2 processor, a single processor can support up to 2 memo...
