Mirrored Memory Configuration Method and Apparatus, and Computer Storage Medium

A computer, comprising:

• a processor;
• and
• a memory storing program code executable by the processor, wherein the program code includes instructions for:
• obtaining a mirrored memory establishment request, wherein the mirrored memory establishment request carries a first identifier of a first physical memory space and a second identifier of a second physical memory space;
• in response to obtaining the mirrored memory establishment request, switching a current state of the computer from an operating system (OS) state to a basic input/output system (BIOS) state through system interruption;
• configuring the first physical memory space and the second physical memory space to be in a mirroring relationship;
• obtaining an identifier of a mirrored memory space corresponding to the first physical memory space and the second physical memory space;
• switching the current state of the computer from the BIOS state to the OS state;
• and
• allocating a memory address range to the mirrored memory space based on the identifier of the mirrored memory space.

A non-transitory computer readable storage medium storing a program that is executable by a processor, the program including instructions for:

• obtaining a mirrored memory establishment request, wherein the mirrored memory establishment request carries a first identifier of a first physical memory space and a second identifier of a second physical memory space;
• in response to obtaining the mirrored memory establishment request, switching a current state of a computer from an operating system (OS) state to a basic input/output system (BIOS) state through system interruption;
• configuring the first physical memory space and the second physical memory space to be in a mirroring relationship;
• obtaining an identifier of a mirrored memory space corresponding to the first physical memory space and the second physical memory space;
• switching the current state of the computer from the BIOS state to the OS state;
• and
• allocating a memory address range to the mirrored memory space based on the identifier of the mirrored memory space.
