Abstract

The invention discloses a BBU capacity restoration method used in a storage system. The BBU capacity restoration method comprises the steps of charging a BBU until the BBU is in a cut-off state to obtain a charged BBU; performing standing on the charged BBU until the battery core activity of the BBU reaches a stable state to obtain a first BBU after standing; performing discharging on the first BBU after standing at a constant current of 800mA until the discharging current of the first BBU after standing is zero to obtain a discharged BBU; performing standing on the discharged BBU to obtain asecond BBU after standing, and reading the electric quantity value of the second BBU after standing in the standing process; and when the electric quantity value of the second BBU after standing is equal to an electric quantity rated value of the BBU, stopping standing on the second BBU after standing to obtain a recovered BBU. Through the method, it is ensured that when the system is in power down, the BBU capacity is not jumped, thereby avoiding loss to a user caused by failure data dump in system power down. Correspondingly, the invention discloses a BBU capacity restoration system used inthe storage system, wherein the capacity restoration system has the abovementioned beneficial effects.

Description

Technical field

[0001] The invention relates to the field of computer communication, and in particular to a method and system for repairing BBU capacity in a storage system. Background technique

[0002] In the field of data storage, BBU (Battery Back-up Unit) is often used as the backup power supply of the system to ensure that the data in the storage system can be dumped to the hard disk in time in the process of power failure. In order to ensure that the data in the system is not lost, but due to the unpredictability of system power failure, it is necessary to ensure that the battery capacity can reach the best performance during the use of the BBU.

[0003] The BBU is composed of a lithium battery and an electronic control circuit. The life of the lithium battery depends on its aging degree. As the use time of the BBU increases, the capacity of the BBU often jumps. This phenomenon is because in the process of using the BBU, High-power discharge occurs in the BBU, or it is caus...
