Problems solved by technology

[0004] There are problems with the existing solutions, the most critical of which are two points: First, the switching process needs to be controlled, and the switching time is related to the capacitive load of the board, circuit design, and PCB routing. Problems with switching time control may easily lead to data loss in storage devices , the actual debugging process is very complicated, and probabilistic problems are prone to occur, and the positioning process is complicated; second, voltage drops are prone to occur during the switching process. Voltage amplitude drops), which leads to many problems in the switching process

Abstract

The present invention provides a hot backup switching system based on a storage system, including a PSU unit, a BBU unit, a first switching device, a second switching device, and a voltage stabilizing circuit, wherein the PSU unit is connected through the first switching device to the storage system; the BBU unit is connected to the storage system through the second switching device; the voltage stabilizing circuit is connected to the output end of the BBU unit, and is configured to output the BBU unit to the first The voltage value of the second switching device is stable below the normal output voltage range of the PSU unit. The invention properly optimizes the traditional BBU unit switching circuit and modifies it into a hot standby scheme, thereby improving the overall reliability of the system.

Description

technical field [0001] The present invention relates to the field of storage systems, and more specifically, to a storage system-based hot backup switching system. Background technique [0002] Unified storage series products, including next-generation platform servers and storage server products, need a solution to save dirty data in the write cache (Dirty Data) when the AC is powered off. The current mainstream solution in the industry is to use the BBU for power backup. After the AC is powered off, the system can switch to the BBU for power supply through the relevant switching circuit. This circuit generally adopts the relatively mature Oring circuit in the industry, and the switching action is completed by the system control. [0003] When the PSU (Power Supply Unit, power supply unit) (AC power supply) AC input is abnormal, the system will detect the AC_FAIL signal of the PSU. The AC_FAIL signal is generally sent to the system 1~10ms before the AC input. After the syst...
