Migration method, computer and device of stored data

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...

AI Technical Summary

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
