Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] The embodiment of the present invention discloses a storage system power backup method, which is applied when the external AC power supply is powered off, see figure 1 As shown, the specific steps include:

[0045] S1: using a group of supercapacitors to supply power to the storage system;

[0046] S2: Turn off the power of irrelevant components, and perform a reset operation on the storage system, while ensuring that the target data in the memory is n...

Abstract

The invention discloses a standby power method for a storage system. When being applied to power down of an external AC (Alternating Current) power supply, the method comprises the steps of supplyingpower to the storage system by use of a group of super-capacitors; turning off the power of irrelative components, carrying out a reset operation on the storage system and meanwhile guaranteeing thattarget data in a memory are not lost during the resetting operation; transferring the target data to a preset hard disc from the memory, wherein the irrelative components are all components, except apreset standby power unit, in the storage system; the standby power unit includes the memory, the hard disc and a preset chip. According to the standby power method for the storage system, the super-capacitors are adopted as a standby power supply; because of the characteristics of the super-capacitors, standby power with maintenance-free can be achieved, the maintenance input in the later periodis reduced, and the defect of low energy density of the super-capacitors is solved by setting a standby power strategy for reduction of power consumption so as to achieve the purpose of transferring and protecting the target data. The invention correspondingly discloses a standby power system and device for the storage system and a readable storage medium.

Description

technical field [0001] The invention relates to data storage, in particular to a storage system power backup method, system, device and readable storage medium. Background technique [0002] The data storage industry has high requirements for data reliability. Generally, it is necessary to ensure that the protection of customer data is foolproof and cannot be lost under any circumstances. For example, when there is a problem with the external power supply, it is necessary to ensure that the system can guarantee the security of the data. [0003] At present, most storage devices are equipped with a BBU (battery backup unit), which is generally a lithium battery pack. When the external AC power fails, the BBU replaces the AC power supply to supply power to the entire system. However, the power backup method of the BBU has several major disadvantages. First of all, the BBU is not maintenance-free and needs to be recharged regularly. Once over-discharge occurs, it will cause p...
