Abstract

The embodiment of the invention provides a data processing method and a data processing device. The data processing device comprises a processor, a memory and a standby power supply. The processor isused for responding to power failure of an external power supply of the data processing equipment, stopping service software from accessing the memory by running firmware, and brushing cache data written in the memory into a disk. The standby power supply is used for supplying power to the processor and the memory when the external power supply is powered down. According to the embodiment of the invention, universal write cache data power-down protection for hardware and software platforms can be realized.

Description

technical field [0001] The embodiments of the present application relate to the field of storage technologies, and in particular, to a data processing method and device. Background technique [0002] When the computer is powered off, the data in the memory of the computer may be lost. Therefore, in order to ensure that the write cache data in the memory is not lost, a backup power is required to persist the write cache data in the memory when the power is off. [0003] Current backup power mainly includes backup power implemented by hardware and backup power implemented by software. For backup power implemented by hardware, a non-volatile dual in-line memory module (non-volatile dual in-line memory module, NVDIMM) is usually used as backup power. Wherein, the NVDIMM may include a dynamic random access memory (dynamic random access memory, DRAM) used as a memory and a NAND FLASH for storing data. When the processor receives a power-off command, it will notify the NVDIMM to ...
