Standby power supply system and storage system

Abstract

The invention discloses a standby power supply system. The standby power supply system comprises a first standby power module and a second standby power module, wherein the first standby power moduleis connected with the first controller group, and the second standby power module is connected with the second controller group; and the first controller group and the second controller group are mutually independent controller groups in the storage system. The two standby power modules are connected with the corresponding first controller group and the second controller group respectively, and the two standby power modules are adopted to achieve standby power supply for different controller groups in the storage system respectively, so that the phenomenon that one standby module realizes standby power supply for the storage controller completely is avoided, and the reliability and the stability of the standby power supply are improved. The invention further discloses a storage system which has the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of computer equipment, in particular to a backup power supply system and a storage system. Background technique [0002] With the continuous development of information technology, in the field of storage system technology, in order to ensure the consistency of tree storage and the integrity of data storage, it is necessary to implement different aspects of consistency protection and integrity protection for the storage system. Among them, the integrity of the power supply to the storage system is one of the most critical factors affecting the reliability and availability of the entire product. Therefore, in the prior art, the power backup system usually supplies power to storage products. [0003] In related technologies, a PSU (Power supply unit, power supply unit) power module is usually used to supply power to storage products. However, the mains power may be interrupted for some reason. At thi...

Problems solved by technology

[0003] In related technologies, a PSU (Power supply unit, power supply unit) power module is usually used to supply power to storage products. However, the mains power may be interrupted for some reason. At this time, there will still be a large amount of customer data stored in the storage product memory If the data in the memory cannot be saved in time, it will inevitably cause the loss of customer data. If some core data is lost, it will inevitably cause serious losses to customers.
