Problems solved by technology

[0004] However, in this method, when the BMC restarts or the CPLD restarts, the GPIO status may change, and the CPLD internal registers will be reset, which may cause the system to be in an uncontrolled state for a certain period of time, and cannot achieve the effect of shielding physical buttons.

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] With the improvement of users' demand for server performance, users' demand for server computing nodes is also increasing. More users choose to centrally place a large number of servers in remote computer rooms or data centers, and use the server monitoring and management module BMC to monitor remote management. The server monitoring and management module can implement operations such as switching on and off and restarting the service, so that users can...

Abstract

The application discloses a control device and method for switching on and off a server, including: BMC, used to obtain configuration instructions from remote users; IO Expander connected to the BMC, used to obtain configuration instructions, and output corresponding level according to the configuration instructions ; The CPLD connected to both the IO Expander and the BMC is used to disable or enable the physical keys for controlling the power on and off of the server according to the power level. In the present invention, relevant configuration instructions for disabling or enabling physical keys are stored in the IO Expander, which is independent of the BMC and CPLD. If the BMC or CPLD is powered off and restarted, the configuration instructions in the IO Expander will not change, and the output level will remain unchanged. , the state of the physical button in the control device being disabled or enabled does not have the possibility of being out of control as in the prior art, which improves the controllability of the server and ensures a stable and safe use state of the server.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a control device and method for switching on and off a server. Background technique [0002] With the improvement of users' demand for server performance, users' demand for server computing nodes is also increasing. More users choose to centrally place a large number of servers in remote computer rooms or data centers, and use the server monitoring and management module BMC to monitor remote management. The server monitoring and management module can implement operations such as switching on and off and restarting the service, so that users can manage the server by remotely connecting to the BMC through the network, and perform operations such as switching on and off and restarting the server without entering the computer room to operate the physical host. At this time, the server is in a remote location. In the computer room, users have limited physical access and protection to...
