Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application discloses multi-server system, including a plurality of servers, every the server all includes:
the logic device is connected with the debugging port corresponding to the server;
the BMC is connected with the logic device;
wherein, the logic devices in each server are connected through a communication link.
Taking the example that the multi-server system includes 2 servers, as shown in fig. 2, each server includes a BMC100 and a logic device 200, and the BMC and the logic device are connected through a communication link and can transmit an exception debug command, an exception debug result, and the like. The present embodiment does not limit the kind of Logic devices, such as CPLD (Complex Programmable Logic Device, chinese full name).
The error detecting ports are UART (Universal Asynchronous Receiver Transmitter/Transmitter), each server has a corresponding error detecting port, a user sends an abnormal error detecting command to the server through the error detecting ports, the running state of the server is monitored, error information of the running of the server is collected, and abnormal error detecting results are output through the error detecting ports.
The debugging port is directly connected to a logic device in the server in an interfacing manner, an abnormal debugging command of a user sequentially passes through the debugging port and the logic device to reach the BMC in the server, the BMC is detected to generate an abnormal debugging result, and the abnormal debugging result is output sequentially through the logic device and the debugging port.
The logic devices in different servers are connected through communication links, and the logic devices realize transmission codes of the debugging ports. The logic device can perform shunt control on the received abnormal debugging command, namely when the abnormal debugging object of the abnormal debugging command is the server, the abnormal debugging command is sent to the BMC in the service, when the abnormal debugging object is other target servers, the abnormal debugging command is sent to the target logic device in the target server, and the target logic device forwards the abnormal debugging command to the target BMC in the target logic device.
By the method, when one debugging port is abnormal, namely the abnormality debugging of the corresponding server can not be carried out through the debugging port, a user can carry out the abnormality debugging on the server through the normal debugging port corresponding to the other server.
It should be noted that, in the present embodiment, the corresponding relationship between the server and the debug port is not limited, and may be a one-to-many relationship, that is, one server corresponds to a plurality of debug ports, for example, the server a corresponds to the debug port 1 and the debug port 2, and the user may perform the exception debug on the server a through the debug port 1 or through the debug port 2. When the debugging port 1 fails, a user can perform exception debugging on the server A through the debugging port 2, and when the debugging port 1 and the debugging port 2 both fail, the user can also perform exception debugging on the server A through other debugging ports by using communication connection between the logic devices.
Of course, a many-to-one relationship may be adopted, that is, a plurality of servers correspond to one debug port, for example, server B and server C both correspond to debug port 3, and a user may perform exception debugging on server B and server C through debug port 1. When the debug port 3 fails, the user can perform exception debug on the server B and the server C through other debug ports (such as the debug port 1 or the debug port 2) by using the communication connection between the logic devices.
Preferably, in order to simplify the internal design of the multi-server system, the servers correspond to the debug ports one to one. For example, server D corresponds to debug port 4, and the user can perform exception debugging on server D through debug port 4. When the debug port 4 fails, the user can perform exception debugging on the server D through other debug ports (such as the debug port 1, the debug port 2, or the debug port 3) by using the communication connection between the logic devices.
According to the multi-server system provided by the embodiment of the application, the logic device is additionally arranged in each server, each debugging port is connected with the BMC through the logic device, and each logic device in the system is connected. When the debugging port corresponding to a certain server fails, the abnormal debugging result of the server can be output through other normal debugging ports through the communication link between the logic devices, and the redundant design of the abnormal debugging under the multi-server system is realized.

in this step, the exception debugging object is another target server, the logic device sends the exception debugging command to the target logic device in the target server, and the target logic device forwards the exception debugging command to the target BMC in the target server to detect the running state of the target server, so as to obtain an exception debugging result. The abnormal debugging result is returned to the logic device in the server through the target logic device.
S104: and sending the abnormal debugging result to a debugging port corresponding to the server.
In this step, when the logic device obtains the exception debug result, it is output through the debug port connected to the logic device, that is, through the debug port through which the user sends the exception debug command.
