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 invention discloses a control device and a method for on and off of a server, which comprises the following steps: a BMC is used for obtaining configuration instructions of a remote user; An IO Expander connected with the BMC, which is used for obtaining a configuration instruction and outputting a corresponding level according to the configuration instruction; The CPLD connected to both IO Expander and BMC is used to disable or enable the physical keys that control the server to switch on and off, depending on the level. In this invention, Relevant configuration instructions to disable orenable physical keys are stored in the IO Expander, independent of BMC and CPLD, If the BMC or CPLD is powered down and restarted, The configuration instruction in the IO Expander will not be changed, the output level will not be changed, and the state in which the physical keys in the control device are disabled or enabled will not be uncontrollable as in the prior art, so that the controllability of the server is improved, and the stability and safety of the use state of the server are ensured.

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...
