Power supply component and storage system

Abstract

The invention relates to the technical field of computer data storage, and provides a power supply component and a storage system. When a computer is powered down, a power supply control module sends a connection signal to an electronic switch according to a power-down trigger signal sent by a second transformer, and a first energy storage device powers a first transformer; a voltage conversion module acquires a direct current from a mainboard power interface, and powers a plurality of data power-down protection devices of the computer after a plurality of times of voltage conversion; controllers of the data power-down protection devices concurrently backup data in a volatile memory to a nonvolatile memory after receiving the power-down trigger signal generated by the second transformer from the power supply control module. By the storage system, multiple data power-down protection devices can be powered through one power supply component, so that convenience in extension for users is improved, and extension cost of the users is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of computer data storage, and in particular to a power supply assembly that provides power supply for a data power-off protection device with data backup function when an abnormal power-off occurs in a computer, and a storage system including the power supply assembly. Background technique [0002] With the development of servers and network storage devices, higher requirements are put forward for the security of data running and stored in computers. However, for some sudden power failures, such as mains power outages or when the power of the computer is cut off by human error, the data running in the central processing unit and memory of the computer will be lost. [0003] In order to solve the above problems, UPS (uninterruptible power supply) or super-capacitor (Super-Capacitor) are usually used in the prior art to provide short-term power supply for the central processing unit and memory of the c...

AI Technical Summary

Problems solved by technology

Since the size of the supercapacitor is usually relatively large, the layout in the main chassis of the computer is relatively cramped

[0007] On the other hand, since each PCB is equipped with a circuit structure that interacts with a supercapacitor to provide a data power-down protection function, the manufacturing cost of the entire data power-down protection device is relatively high

[0008] In addition, because the data power-off protection device backs up the data in the memory to a non-volatile memory (such as NAND flash memory) according to the capacity of the entire memory when the computer unexpectedly loses power, so when the user includes the memory When upgrading the data power-down protection device of non-volatile memory and non-volatile memory, it is often impossible to predict whether the total charge storage capacity of the supercapacitor contained in the computer can meet the needs of data backup at the moment

[0009] When the computer unexpectedly loses power, it may happen that the power in the supercapacitor is not enough to back up all the data in the central processing unit and memory to the non-volatile memory, which will lead to the instability of the computer system; Supercapacitors often do not know how much supercapacitor capacity needs to be added

[0010] Because the price of the supercapacitor itself is relatively expensive, too much connection of the supercapacitor will cause waste, and too little connection of the supercapacitor will cause the power stored in the supercapacitor to be insufficient when the computer is unexpectedly powered off, causing the computer system to Instability and consistency and many other problems occur
