Mutually combination.Describe the application in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Fig. 1 shows the operating method or the base of server for the baseboard management controller that can apply the server of the application
The exemplary system architecture 100 of the embodiment of the operation device of board management controller.
As shown in figure 1, system architecture 100 can include baseboard management controller (BMC, Baseboard Management)
101st, IPMI (IPMI, Intelligent Platform Management Interface) 102, distal end
Device 103 and network 104.Wherein, baseboard management controller 101 is IPMI (Intelligent
Platform Management Interface, abbreviation IPMI) provide system operator can pass through network or standard serial
The transmission form of port (Serial) monitors the component health parameters of various elements in calculator device, and such as center processing is single
Operating state, the rotating speed of radiator fan, the temperature of main frame board chip and its voltage of member etc..System operator can be to needing prison
The critical value of the section sets sensing of control, the controller of IPMI 101 can lead to when sensing less than normal condition
Cross send e-mails, send Simple Network Management Protocol (Simple Network Management Protocol) etc. come mode lead to
Know system manager's process problem.In addition, by the cooperation of hardware and software, IPMI 101 can also increase
Plus the function that remote side administration and system are replied, allow system operator can be learnt in distal end system be currently in which kind of state,
In such as shutting down, starting shooting, operating system delays machine, and assigns start, shuts down and restart etc. and order.Specifically, intelligent platform pipe
Manage interface 102 can by baseboard management controller 130 (Baseboard Management Controller, hereinafter referred to as
BMC) purpose of remote monitoring far end device 103 is realized.For example, numeral can be periodically polled in baseboard management controller 101
Sensor monitors working condition that far end device 103 is current, and is communicated by system management bus interface with main frame.
That is, baseboard management controller 101 can be considered as an independent arithmetic element, so baseboard management controller 130 generally has
Independent firmware drives the correlation function of baseboard management controller 101.
It should be noted that the operating method of the baseboard management controller for the server that the embodiment of the present application is provided is general
Performed by baseboard management controller 101, correspondingly, the operation device of the baseboard management controller of server is generally positioned at substrate
In Management Controller 101.
It should be understood that the number of the baseboard management controller, IPMI, far end device and network in Fig. 1
It is only schematical.According to needs are realized, can have any number of baseboard management controller, intelligent platform management to connect
Mouth, far end device and network.
With continued reference to Fig. 2, one of the operating method of the baseboard management controller of server according to the application is shown
The flow 200 of embodiment.The operating method of the baseboard management controller of the server, comprises the following steps：
Step 201, the pressing operation performed to the button set on the baseboard management controller of server is monitored.
