Test method, device and system for independent power supply of BBU (battery backup unit) and readable storage medium

Abstract

The invention discloses a test method, device and system for independent power supply of a BBU (battery backup unit) and a readable storage medium. The test method comprises the following steps: judging whether a rectification module outputs a power-down signal within a first period after power-down of data storage equipment after detection of power-down of the data storage equipment; if so, judging whether a controller outputs an enable signal within a second period after receiving the power-down signal; if so, judging whether the BBU supplies power to the data storage equipment immediately after receiving the enable signal and outputs a backup preparation signal to the data storage equipment within a third period, so as to facilitate data backup for the data storage equipment, if so, determining that the BBU supplies power independently normally, otherwise, determining that the BBU supplies power independently abnormally. The test of independent power supply of the BBU in the power supply preparation phase is achieved, normal power supply of the BBU to the data storage equipment is effectively ensured, and reliability and safety of power supply of the BBU to the data storage equipment are improved.

Description

technical field [0001] The invention relates to the technical field of equipment power supply testing, in particular to a testing method, device, system and readable storage medium for independent power supply of a BBU. Background technique [0002] In the field of network data storage technology, data backup is extremely important for any enterprise. Once data is lost or damaged, it will have a significant impact on the daily production of the enterprise, and even cause irreparable losses. For data storage devices, it should be possible to back up all relevant data without loss. [0003] Under normal circumstances, the mains power is rectified by the rectifier module to supply power to the data storage device. If the mains power is suddenly cut off, the data storage device will not be able to continue to back up data. In order to solve this problem, a BBU (Battery Backup Unit, battery backup unit) is usually used in the prior art to immediately supply power to a data stora...

AI Technical Summary

Problems solved by technology

In the prior art, the function of the BBU is usually verified when the BBU is in a normal working state, that is, when the BBU has already supplied power to the data storage device. Whether the data storage device can be powered normally reduces the reliability and security of the BBU's power supply to the data storage device
