Abstract: Embodiments of the present disclosure provide a write request processing method, a processor, and a computer. A first computer is connected to a second computer, respective operating systems run on the first computer and the second computer respectively, the first computer includes a first processor, the first processor is connected to a second processor of the second computer by using a system bus, the first computer includes a first memory address space, a second memory address space of the second computer is a mirror address space of the first memory address space, and the first processor mirrors data written into the first memory address space to the second memory address space by using the system bus, which can reduce mirroring operation latency and improve IOPS performance of a system.
