Topology redundant standby power achieving method, system and device and readable storage medium

Abstract

The invention discloses a topology redundant standby power achieving method. The method includes: detecting status information of multiple standby power units in an electrical storage device and an external power supply powering a storage system; when the electrical storage device is detected to meet a charging condition, charging the electrical storage device with the external power supply afterraising voltage of the external power supply; when the electrical storage device is detected to meet a discharging condition, powering the storage system through the electrical storage device after reducing the voltage of the electrical storage device; wherein the charging condition lies in that power of any one standby power unit is lower than a first default value and the external power supply performs normal power supply; the discharging condition lies in that the external power supply suspends power supply. By the arrangement, selection of parts is low in cost, flexible space distributionand less space occupation are achieved, voltage of the electric storage device is higher than that of the external power supply and the storage system, storage capacity of the electrical storage device is large, and demands of the system for standby power can be met. The invention correspondingly discloses a topology redundant standby power achieving system and device and a readable storage medium.

Description

technical field [0001] The invention relates to the field of storage servers, in particular to a topology redundant power backup method, system, equipment and readable storage medium. Background technique [0002] In the era of cloud computing, mass data storage and transmission requires a large-capacity storage carrier platform. However, usually such a large-capacity storage carrier is used during the operation of the storage service system to prevent user data from being delayed in time due to abnormal interruption of external power supply. The storage system is lost, so the BBU (Battery Backup Unit, backup battery pack) backup method is specially introduced to deal with the protection. When the BBU is used as backup power, it should ensure its own activity and sufficient power, and it needs to be charged and discharged regularly. In the traditional hardware design of the storage server field, especially the flash memory system, due to the limitation of its own mechanism ...

AI Technical Summary

Problems solved by technology

[0003] The traditional backup method, one is to use an external independent BBU for backup; the other is to use multiple capacitors in parallel for direct charging backup; the former backup method, although it can solve the problem of storage capacity problem, but requires additional space, and at the same time has a high cost and takes up more resources; although the latter backup power method can solve the space problem to a certain extent and reduce the cost, it is limited by the problem of insufficient capacity. If the capacity is increased , also need to sacrifice space, and occupy a higher cost
