The method and system of Management Controller error protection
Background technology
During programmable controller work in server, it may occur that dysfunction, preset program etc. can not be performed ask
Topic.Such case is run into, it is necessary to be resetted to programmable controller.The processing mode of prior art is as follows：It can compile
The reset signal of range controller is connected in house dog watchdog circuits or equipment, and programmable controller is constantly to watchdog
Circuit sends pulse signal, and when programmable controller breaks down, program can not perform pulse signal and can not send.
Watchdog circuits constantly carry out timing, and the value of timing is reset after pulse signal is received.When timing time reaches preset value
When, because pulse signal does not issue, timer causes timing time to reach predetermined value, watchdog circuits without clearing in time
Reset signal is sent to programmable controller, ensures programmable controller normal work.
In server design, Management Controller is often used to the fan of server, voltage, power consumption, error message
Etc. being monitored and control.Management Controller is also one kind of above-mentioned programmable controller, to ensure server reliability, is also needed
Management Controller is resetted when Management Controller breaks down.
Management Controller needs to be initialized when electrifying startup, and it, which is initialized, needs a period of time, typically 1
More than minute.If Management Controller is monitored and resetted using above-mentioned prior art, its timing time must exceed
It the time that Management Controller initialization needs, otherwise can cause Management Controller in electrifying startup, not complete initialization, just exist
Resetted under the control of watchdog circuits, thus the phenomenon that can not start.And timing time it is long the shortcomings that be, managing
Recover normal work, it is necessary to wait and be lot more time to reset when controller breaks down.This can cause Management Controller to exist
In some time can not monitoring server important information, be unfavorable for the reliability of server.

Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.
As shown in figure 1, the system of controller failure protection is managed in a kind of server of the present embodiment, including server, clothes
The Management Controller 1 of business device debugs the signal input part company that signal output part passes through serial port data line 2 and failure protecting device 4
Connect, the reset signal output end of failure protecting device 4 is connected by the reset signal input of reseting data line 3 and Management Controller
Connect, so as to be resetted by failure protecting device 4 to Management Controller 1.
Management Controller 4 is provided with comparison module 41 and timing module 42, and comparison module 41 is used to adjust Management Controller 1
The data sent of examination serial ports are judged, when debug that serial ports sends is the initialization information of Management Controller 1, is not then done and are located
Reason；What is sent when debugging serial ports is to be spaced the specified data of transmission after the completion of Management Controller 1 initializes, then by the timing mould
Block 42 starts timing, and when receiving the specified data next time, the value of the timing of timing module 42 is reset；When the value of timing reaches
During to preset value, failure protecting device 4 does not receive the specified data of Management Controller transmission, then will be managed by reset signal
Controller 1 resets.Further, the preset value of the timing of timing module 42 is 30 seconds.
Present invention also offers a kind of method that controller failure protection is managed in server, comprise the following steps：
The Management Controller 1 of server is debugged into the signal input part that signal output terminates to failure protecting device 4 first,
The reset signal input of the reset signal output end connection management controller 1 of failure protecting device 4, to pass through error protection
Device 4 controls Management Controller 1 to reset.
When Management Controller 1, which breaks down, to be initialized, Management Controller 1 is continuously protected by debugging serial ports to failure
Protection unit 4 sends current init state information, for indicating the initialization degree of Management Controller 1；At the beginning of Management Controller 1
During beginningization normal work, Management Controller 1 can be spaced sends the data specified by debugging serial ports to failure protecting device 4.
Then the data that failure protecting device 4 is sent by the debugging serial ports of Management Controller 1 are judged, when debugging serial ports
When what is sent is the initialization information of Management Controller 1, then do not process；When debugging serial ports send be Management Controller 1 at the beginning of
The specified data of transmission are spaced after the completion of beginningization, then failure protecting device 4 starts timing, and finger described in identical is received in next time
Fixed number according to when, the value of the timing of failure protecting device 4 is reset；When the value of timing reaches preset value, failure protecting device 4 does not connect
The specified data of Management Controller transmission are received, then are resetted Management Controller 1 by reset signal.
Wherein failure protecting device 4 is complex programmable logic device (CPLD) or on-site programmable gate array FPGA, CPLD/
Comparison module and timing module are provided with FPGA.
Specifically, as shown in Fig. 2 the present embodiment is constantly sent when Management Controller 1 initializes by debugging serial ports
Current init state information, indicates which step current Management Controller 1 has been initialised to；Management Controller completes initialization
And during normal work, just send the data specified to CPLD/FPGA by debugging serial ports at predetermined time intervals.
CPLD/FPGA is judged that what such as debugging serial ports was sent is management control according to the data sent of debugging serial ports
The initialization information of device 1, then do not process；What if debugging serial ports was sent is after the completion of Management Controller 1 initializes, periodically hair
The specified data sent, then CPLD/FPGA starts timing, and after the specified data are received again by, resets the value of timing.Work as meter
When value when reaching preset value, pass through reseting signal reset Management Controller 1.
When can shorten Management Controller failure by the method and system of the present invention, it is carried out to reset and recovers institute
The time needed；Increase the time of the normal work of Management Controller 1, lift the reliability of server.
The technology contents of the not detailed description of the present invention are known technology.
