Abstract
The invention discloses an intelligent fan speed regulating method for a server, and belongs to the technical field of computers. The operation method comprises the following steps that, firstly, fan control strategies configured for a CPU, an internal storage and PCIE equipment are debugged through heat dissipation and written into configuration files of an FW, and the FW maintains the configuration files; secondly, a BIOS detects the information of the CPU, the internal storage and the PCIE equipment in the current system in a starting process of the server, the information is sent to the FW through an LPC channel, and the FW stores the information in storage devices; finally, the FW selects one fan control strategy suitable for the current server configuration for running from the configuration files according to the current actual server configuration. Compared with the prior art, waste of fan allowance can be reduced effectively, system power consumption and server noise are lowered, flexible use of the FW configuration files lowers difficulty of customized development and maintenance of the FM, and the reliability and maintainability of the system are improved.
Description
Technical field
The present invention relates to field of computer technology, specifically a kind of intelligent fan speed regulating method of server.
Background technology
BIOS is the abbreviation of English " Basic Input Output System ", and literally rear Chinese is exactly " Basic Input or Output System (BIOS) ".Be one group and be cured to the program on a rom chip on the interior mainboard of computing machine, the program of the most important basic input and output of its in store computing machine, system configuration information, the rear self-check program of start and system self-triggered program.Its major function provides the bottom, the most direct hardware setting and control for computing machine.
PCI-Express is up-to-date bus and interface standard, PCIe belongs to the point-to-point binary channels high bandwidth transmission of high speed serialization, the devices allocation connecting exclusively enjoys channel bandwidth, not shared bus bandwidth, the main active power management of supporting, error reporting, end-to-end reliability transmission, the functions such as hot plug and service quality (QOS).PCIe transfers to PCI-SIG(PCI particular interest tissue) certification issue after be just renamed as " PCI-Express ", be called for short " PCIE ".
FW is server monitoring administrative unit; FAN is fan module.
Along with the development of computer technology, server is more and more to the kind of various peripheral equipment requirements, and the affect difference of these peripheral hardwares on system radiating, for example GPU(graphics process) card thermal value is larger, and PCIE extrapolation network interface card thermal value is relatively little.Meanwhile, arrange in pairs or groups different CPU and internal memory number are not identical on the impact of server system heat radiation yet.In traditional heat dissipation design, generally can select the configuration of thermal value maximum to do heat radiation test, provide the cooling curve of this kind of configuration, for the heat radiation speed governing of all configurations.Do like this and can meet all server configuration heat radiation requirements, but at server configuration CPU, amount of memory is less, when PCI allocation E outer plug-in card is less, still adopt this kind of fan speed-regulating strategy, wasted undoubtedly a lot of fan surpluses, cause server energy consumption to raise, noise strengthens.How can configure and carry out rotation speed of the fan regulation and control according to server flexibly, can not cause again energy consumption waste and noise to strengthen simultaneously just becomes urgent problem.
Summary of the invention
Technical assignment of the present invention is to provide a kind of intelligent fan speed regulating method of server.
Technical assignment of the present invention is realized in the following manner, and FW is connected with TACH signal by pwm signal with at least one FAN, and FW and BIOS are interconnected by lpc bus, and BIOS and internal memory, PCIE equipment pass through SMBus, PCIE bus is interconnected;
Method of operating is as follows:
First, CPU is debugged out in heat radiation, internal memory, and the fan regulation and controlling strategy of PCIE equipment configuration, is written in the configuration file of FW, safeguards this configuration file by FW; Secondly, BIOS detects the CPU in current system in server start process, internal memory, and the information of PCIE equipment, sends to FW by LPC passage, and FW is kept at information in memory device; Finally, FW, according to the server configuration of current reality, selects the fan regulation and controlling strategy operation of an applicable current server configuration from configuration file.
Described pwm signal is the fan rotating speed signals arranging, and TACH signal is the fan rotating speed signals that reads acquisition.
Described BIOS in server start process, detect current system in the information of each equipment comprise equipment number and unit type.
The intelligent fan speed regulating method of a kind of server of the present invention compared to the prior art, can realize according to current server flexible configuration and select optimal fan regulation and controlling strategy, reach the object of server intelligent fan speed governing, in the situation that system configuration is low, can effectively reduce the waste of fan surplus, reduce system power dissipation and server noise, simultaneously the flexible use of FW configuration file, reduce the difficulty of the customized development maintenance of FW, improved the reliability and maintainability of system.
