Problems solved by technology

However, the BBU also has quality risks: although the storage system can detect the quality of the BBU when the system starts, some BBUs start to become worse and worse after the storage system is used.
[0004] Therefore, for such a BBU, the storage system needs to implement a detection method to prevent the BBU from being unable to provide continuous power supply when a real accidental power failure occurs.

Abstract

The invention discloses a method and system for detecting a battery backup unit. The method includes: cutting off the power supply of a power source through a complex programmable logic device; triggering the power supply of the battery backup unit; recovering the power supply of the power source through the complex programmable logic device after the power supply is cut off for a set time; calculating the discharge capacity of the battery backup unit in the set time, and judging whether the discharge capacity is in a standard range or not. By the arrangement, the method has the advantages that the battery backup unit which has a quality problem during the operation of a storage system can be detected by detecting the health state of the battery backup unit, and accordingly a client can be reminded to replace the battery backup unit as soon as possible, the power supply module of the storage system is perfected, the power supply ability of the storage system is guaranteed, the potential safety hazard of data loss is avoided, the safety operation of the storage system is guaranteed, and the reliability of the storage system is increased.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method and system for detecting an electric storage battery. Background technique [0002] In the storage field, most storage system designs use a battery backup unit (BBU for short) to ensure the power supply security of the storage system. When the storage system is unexpectedly powered off, the BBU can continue to supply power for a short period of time, so that the temporary data in the storage system can be safely and reliably written to the hard disk, ensuring the stability of the data in the storage system. [0003] For the BBU, the storage system has a requirement: the continuous power supply time of the BBU is a time estimated by the storage system based on the design. Only when the continuous power supply time of the BBU meets the requirements of this time can the data reliability of the storage system be guaranteed. However, BBUs also have quality risks: Although t...
