Interconnection architecture for main board and BBU

Abstract

The invention provides an interconnection architecture for a main board and a BBU (Battery Backup). A logic compiling module maintains the time series status of a BBU module; a power module is connected with the logic compiling module, and fault signals of the power module are filtered by the logic compiling module and then sent to a detection control module and a main board management module as interrupt signals; the detection control module is connected with the BBU module and the logic compiling module respectively, the logic compiling module detects the in-place status of the power module every preset time period, after the logic compiling module detects power-off of the power module, the logic compiling module sends a power module fault signal to the detection control module, the detection control module sends an enabling signal to the BBU module, and the BBU module begins discharging when receiving the enabling signal. When the power module is powered off, the power of the BBU module can enable data cached in a server host to be stored into a system disk within certain time, thereby avoiding data loss caused by power-off.

Description

technical field [0001] The invention relates to the field of server motherboards, in particular to an interconnection architecture between a motherboard and a BBU. Background technique [0002] When the server is working, when there is a problem with the power supply, such as a power outage or a hardware failure of the server, it is easy to cause the host to suddenly shut down, the data stored in the controller cache is lost, and sometimes the temporary data files in the system disk cannot be accessed. Saving will affect the normal work of the server later. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides an interconnection architecture between a motherboard and a BBU, including: a BBU module and a motherboard; [0004] The main board includes: logic compilation module, main board management module, detection control module, power supply module; [0005] The main board management mod...
