Embodiment Construction

[0043] Embodiments of the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, and therefore are only examples, and cannot be used to limit the protection scope of the present invention.

[0044] figure 1 The implementation flow diagram of the BBU power-down protection implementation method provided by the present invention is shown, which specifically includes the following steps:

[0045] In step S101, when it is detected that the BBU in the storage system enters the power-off fault state, the fault type of the BBU currently in the power-off fault state is judged, and the fault type of the BBU includes a fatal fault and a non-fatal fault;

[0046] In step S102, if it is determined that the BBU currently in the power-off fault state is a fatal fault, then control the controller corresponding to...

Abstract

The invention relates to the technical field of servers, and provides a BBU power-down protection implementation method and system, and the method comprises the steps: judging the fault type of a BBUin a power-down fault state when the BBU in a storage system is detected to enter the power-down fault state; if it is judged that the BBU in the power-down fault state currently is a fatal fault, controlling a controller corresponding to the BUU in the power-down fault state to enter a service mode; if it is judged that the BBU in the power-down fault state currently is a non-lethal fault, executing a power-down protection action on the BBU in the power-down fault state currently according to a pre-configured non-lethal fault management script tool. The defect of a single-control write-distance mode is overcome, the storage system is in a double-control running state, and the running reliability and stability of the storage system are improved.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a BBU power-down protection implementation method and system. Background technique [0002] In the field of storage server battery backup unit (Battery Backup Unit, BBU) power-down protection design, in the current storage design, power supply units (Power supply units, PSU) and BBU are integrated design, when replacing the PSU, it is also necessary to replace the BBU Unplug, at this time the storage system will send out an alarm, and the controller corresponding to the power-off BBU will enter the write-back mode. After 5 minutes, the controller will enter service, and correspondingly, the controller of the other redundant BBU will enter write-through mode. [0003] However, in the single-controller write-through mode, the performance of the storage system is poor, and there is also a risk of unreliable operation. Contents of the invention [0004] Aiming at the ...
