Problems solved by technology

[0005] The data written to the cache, the mirrored data, and the data read from the cache will not be physically separated in the memory, so if the system has a large number of memories, the battery must simultaneously All the memory sticks are powered, the power consumption is too large, and the cost is too high

Embodiment 1

[0027] like figure 1 As shown, the method for device power-down protection in the embodiment of the present invention may include the following steps:

[0028] Step S102: When the device is powered off, start a backup power supply to supply power to the device;

[0029] In the embodiment of the present invention, the backup power supply may be a battery or the like; the central processing unit CPU may be triggered to start the backup power supply to supply power to the device.

[0030] Step S104: In the standby power supply mode, physically separate the data of the write cache CACHE from the mirror data and the data of the read cache CACHE.

[0031] In the embodiment of the present invention, the data in the cache cache can generally be divided into three parts: writing the cache, mirroring the board, and reading the cache. For example, there are two memory sticks of the device A and B. Before power failure, the write cache data and mirror data are stored in memory stick A, ...

Embodiment 2

[0043] like Figure 4 As shown, an electronic device provided in an embodiment of the present invention may include:

[0044] The backup power supply 402 is used to supply power to the device when the device is powered off;

[0045] The data separation unit 404 is used to physically separate the data of the write cache CACHE from the mirror data and the data of the read cache CACHE in the backup power supply mode when the device is powered off;

[0046] The write cache data protection unit 406 is configured to perform security protection processing on the data of the write cache CACHE in the backup power supply mode.

[0047] The security protection processing performed by the write cache data protection unit may be specifically writing the data of the write cache CACHE into a safe in the backup power supply mode, or may be writing the data of the write cache CACHE in the backup power supply mode. Do an automatic refresh.

[0048] Further, as Figure 5 As shown, optionally...

Embodiment 3

[0056] An embodiment of the present invention provides a network system, such as Figure 7 As shown, the network system may include: a computer 701 , a router 702 , a server 703 and a storage device 704 . exist Figure 7 In the network system shown, any electronic device among the computer 701 , router 702 , server 703 and storage device 704 may include: a backup power supply, a data separation unit, and a write cache data protection unit. The function of each unit is similar to that of Embodiment 2, so the description will not be repeated here.

[0057] Those skilled in the art can find Figure 7 Other electronic devices such as switches and base stations are added to the network system shown, and any of the added electronic devices may include a backup power supply, a data separation unit, a write cache data protection unit, and the like.

[0058] Each unit of the system in the embodiment of the present invention may be integrated in one device, or distributed in multiple...

Abstract

The embodiment of the invention discloses a method of power failure of equipment, comprising the following steps: initiating a standby power supply to provide power for equipment, when power failure occurs in the equipment; separating the data writing buffer CACHE separately with image data and the data reading the buffer CACHE in a physical state; carrying out safety protection treatment on the data writing the buffer CACHE. The embodiment of the invention also discloses electronic equipment and a network system. The embodiment of the invention has the advantages of reducing the total power consumption of the equipment when power failure occurs, improving the time of preparing electricity for the standby power supply and reducing cost.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a method for device power-down protection, electronic equipment and a network system. Background technique [0002] Storage devices generally implement power-off protection measures for the data in the cache in the system, that is, when the system is powered off, the data in the cache is usually refreshed automatically through the battery to keep the data in the cache from being lost, or The data in the CACHE is moved to the safe through the battery. At present, most of them tend to adopt the latter method, that is, move the data in the CACHE to the safe. In general, the data in the cache can be divided into three parts: the local board writes the cache, mirrors the board, and the local board reads the cache. [0003] The storage device needs to use a battery as backup power to write the data in the cache to the safe. After power failure, it needs to supply power to th...
