Abstract

The invention discloses a data brushing-down system, and a method comprises the steps that a processor sends a power supply instruction to a controller when detecting that equipment is powered off; sending a first data brushing control command to the controller; when it is detected that equipment power supply returns, sending a second data brushing-down control command to the controller; enablingthe controller to control a preset standby battery to supply power to the equipment; generating and sending a first data brushing-down instruction to a device memory; generating and sending a second data brushing-down instruction to a persistent memory; enabling the device memory to swipe down the data to the persistent memory according to the first data swipe-down instruction; enabling the persistent memory to brush down the data to the disk according to the second data brushing-down instruction; and arranging the persistent memory between the device memory and the disk. According to the method, the non-volatility and high efficiency of the persistent memory are fully utilized, the data brushing efficiency is greatly improved, the data is prevented from being lost, and the data reliability is improved. The invention further discloses a data brushing-down device and equipment and a storage medium, and the corresponding technical effects are achieved.

Description

technical field [0001] The present invention relates to the field of storage technologies, in particular to a data downloading system, method and computer-readable storage medium. Background technique [0002] When using storage devices, users need to pay special attention to power outage scenarios, whether it is a single controller or multiple controllers. If a sudden power outage will cause device data loss, it may cause great harm to users. Therefore, the power-down protection mechanism is particularly important. For the current unified storage device, using a backup battery unit is a relatively common solution for handling power-failure protection scenarios. Specifically, when the unified storage device encounters a sudden power failure, due to the existence of the backup battery unit, the device will not be shut down immediately due to the power failure, so that the data in the memory will not be lost immediately. So as to achieve the function of power failure protect...
