The method of the autonomous switching of the control that the cold and hot backup of two-shipper provided the present embodiment below independently switches and information handling system is described.
The autonomous changing method of a kind of cold and hot backup of two-shipper, comprises the following steps:
S1, provides the two-shipper control that cold and hot backup independently switches and information handling system 10;
S2, to system power supply, main frame 100 and standby host 200 work simultaneously, enter startup self-detection state, obtain primary processor 120 and the duty for processor 220;
S3, the mode of operation that system will be taked is judged according to the primary processor 120 got and the duty of standby processor 220, if main frame 100 and standby host 200 all normally work, then main FPGA110 control energy supply control module 500 disconnects standby host power supply, and system enters cold standby mode of operation; If main frame 100 normally works, standby host 200 has exception, then main FPGA110 control energy supply control module 500 disconnects standby host power supply, and inner marker standby host fault, system enters main frame list remaining duty; If it is abnormal that standby FPGA210 detects main frame 100, then control energy supply control module 500 for FPGA210 and disconnect host power supply, system enters standby host list remaining duty.
In step S1, the control that the cold and hot backup of described machine independently switches and information handling system 10 can be the maximum system of all functions module comprised in embodiment, also can be the minimum system be only made up of main frame 100, standby host 200, energy supply control module 500, power input interface 900 and power output interface 910, or the combination of above-mentioned minimum system and partial function module.
In step S2, give system power supply by power input interface 900, main frame 100 and standby host 200 obtain power supply by energy supply control module 500 and start working, and now main frame 100 and standby host 200 all externally do not carry out information interaction.The method obtaining the duty of primary processor 120 and standby processor 220 described in the present embodiment is: carry out heartbeat detection by serial ports between primary processor 120 and main FPGA110, main FPGA110 obtains the information whether primary processor 120 normally works, carry out heartbeat detection between processor 220 and standby FPGA210 by serial ports, standby FPGA210 obtains the information whether standby processor 220 normally works.

Further, system can switch between cold standby pattern and hot-standby mode.
1) cold standby pattern switches hot-standby mode
If startup self-detection main frame 100 and standby host 200 all without exception, then system enters cold standby mode of operation, now, primary processor 120 is monitored own resource expense and is obtained power consumption information by the voltage and current detection circuit in energy supply control module 500, when the excessive and power consumption of resource overhead still has surplus, main frame 100 controls energy supply control module 500 repeat circuit 510 and closes as standby host is powered and by working in the information of hot-standby mode with standby FPGA210 interconnect signal line delivery request standby host 200.Standby host 200 detects interconnect signal line after starting shooting and works in hot-standby mode.Under hot-standby mode, standby host 200 bears part evaluation work simultaneously, but does not externally export the information such as serial ports, network interface, image, Energy control.
2) hot-standby mode switches cold standby pattern
Under Hot Spare mode of operation, if by the voltage and current detection circuit in energy supply control module 500, main frame 100 detects that system power dissipation transfinites, then can to standby host 200 power-off, system enters cold standby mode of operation.
It should be noted that, when retraining without other, the changing method of the cold and hot backup of above-mentioned two-shipper autonomous changing method method and cold standby pattern and hot-standby mode is equally applicable to the situation of many external function modules, Multi-netmouth, Multi-serial port, many buttons, many picture output signals line.
