Abstract
The invention discloses a method of a BMC for adjusting a CPU alarm temperature based on CPUs with different powers, and belongs to the technical field of servers, wherein a hardware structure comprises a ROM chip and a BMC of the server, and a BIOS program of the ROM chip is modified so as to enable the BIOS program to be combined with the BMC. The method specifically comprises steps as follows: the BIOS of the ROM chip detects the model of the CPU; the BIOS obtains the power of the CPU according to the model of the CPU; the BIOS computes the CPU alarm temperature according to the corresponding relation between the power of the CPU and the working alarm temperature of the CPU; the BIOS writes the value (of the CPU alarm temperature) into a register of a monitoring chip; the BIOS informs the BMC to read the value of the register; and the BMC sets the value read in the register as the alarm temperature value of the current CPU. In the invention, after the CPU of a server main board is replaced, the BMC can correctly obtain the alarm temperature of the current CPU, so as to ensure that the BMC can correctly monitor the working state of the CPU based on different CPUs.
Description
Technical field
The present invention relates to a kind of server technology field, specifically a kind ofly having BMC (BaseboardManagement Controller, baseboard management controller) on the server master board, how BMC realizes adjusting according to the CPU of different capacity the method for CPU overheat warning Temperature numerical in the monitor message, and promptly a kind of BMC adjusts the method for CPU alarm temperature according to different capacity CPU.
Background technology
Along with development of science and technology, it is extensive all the more that server is used, and along with the development of server technology, all begins in the middle-and high-end server to realize monitoring and management to server with independent BMC.
BMC (Baseboard Management Controller, baseboard management controller) supports the IPMI standard of industry standard.This specification description be built into management function on the mainboard.These functions comprise: local and remote diagnosis, control desk support, configuration management, hardware management and fault are got rid of.
BMC is as server master board monitoring and Management Controller, the monitoring of main charge server switching on and shutting down control and information such as mainboard voltage and temperature, and be one of its critical function to the monitoring of cpu temperature, BMC need obtain the current temperature of CPU and and the comparison of its ultimate temperature, if the temperature range of going beyond the limit of then demonstrates warning message.Because but the alarm temperature of the different CPU of same train power is different, though can be provided with one by BMC meets the minimum temperature alarm thermal constant of all CPU and comes to use on all CPU, but do like this and imperfection, because when the actual alarm temperature of high-power CPU does not also reach alarm threshold, monitor message just begins to have reported to the police.
If can solve the temperature extremes value of the CPU of the different capacity of being installed on the current as can be known mainboard of BMC, can realize that then BMC adjusts cpu temperature alarm numerical value according to the CPU of different capacity.How to realize adjusting cpu temperature alarm numerical value according to the CPU of different capacity with BMC in the server master board, be the problem that the current techniques personnel need solve.
Summary of the invention
Technical assignment of the present invention provides a kind of after server master board is changed CPU, BMC can accurately obtain current C PU alarm temperature, can come the BMC of the duty of accurate monitoring CPU to adjust the method for CPU alarm temperature according to different capacity CPU according to different CPU to guarantee BMC.
Technical assignment of the present invention realizes that in the following manner hardware configuration comprises rom chip, BMC and the monitoring chip of server, and the bios program of revising rom chip matches with BMC; The concrete steps of described method are:
(1), BIOS detects the model of CPU;
(2), BIOS obtains the power of CPU according to the model of CPU;
(3), BIOS calculates this CPU alarm temperature according to the power of CPU and the corresponding relation of CP work alarm temperature;
(4), BIOS is written to this numerical value in the register of monitoring chip;
(5), BIOS notice BMC removes to read the numerical value of this register;
(6), numerical value is set to current C PU alarm temperature numerical value in the register that reads of BMC.
Monitoring chip in the step (4) is SUPERIO or hardware monitor chip.
CPU alarm temperature numerical value is the temperature extremes value of CPU.
BIOS (Basic Input Output System, Basic Input or Output System (BIOS)) is one group of program that is cured in the server on the mainboard on the rom chip, the program of the most important basic input and output of its in store computing machine, system's configuration information, start back self-check program and system's self-triggered program.Its major function provides the bottom, the most direct hardware setting and control for server.
BMC of the present invention has the following advantages according to the method that different capacity CPU adjusts the CPU alarm temperature: after server master board is changed CPU, BMC can accurately obtain current C PU alarm temperature, can come the duty of accurate monitoring CPU according to different CPU to guarantee BMC; Reasonable in design, running convenience, thereby, have good value for applications.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is adjusted the process flow diagram of the method for CPU alarm temperature according to different capacity CPU for BMC.
Embodiment
The method of BMC of the present invention being adjusted the CPU alarm temperature according to different capacity CPU with reference to Figure of description and specific embodiment explains below doing.
Embodiment:
BMC of the present invention adjusts the method for CPU alarm temperature according to different capacity CPU, and hardware configuration comprises rom chip, BMC and the monitoring chip of server, and the bios program of revising rom chip matches with BMC; The concrete steps of described method are:
(1), BIOS detects the model of CPU;
(2), BIOS obtains the power of CPU according to the model of CPU;
(3), BIOS calculates this CPU alarm temperature according to the power of CPU and the corresponding relation of CP work alarm temperature;
(4), BIOS is written to this numerical value in the register of monitoring chip;
(5), BIOS notice BMC removes to read the numerical value of this register;
(6), numerical value is set to current C PU alarm temperature numerical value in the register that reads of BMC.
Monitoring chip in the step (4) is SUPERIO or hardware monitor chip.
For example: on a server master board that has a BMC, laid the CPU of INTEL 55 series on the mainboard, after BIOS detects its CPU model and is INTEL 5560, will learn that its power is 95W, be 81 degree according to the alarm temperature that the computing formula of cpu power and CPU work alarm temperature calculates this CPU this moment.BIOS is written to this numerical value 0x51 in the PECI register of the SUPERIO chip of server then, and notice BMC has upgraded this register value, allow BMC go to read this register value, BMC reads the CPU alarm temperature numerical value that upgrades original setting after these data.When the temperature that detects CPU as BMC is higher than this temperature, will send warning information.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
