Abstract
The invention discloses an efficient and energy-saving method for adjusting and controlling fans of a SmartRack cabinet. The method includes the steps that fan rotating speed control meters are installed in BMC processing chips of server nodes of the SmartRack cabinet, and the fan rotating speeds required by the nodes are determined through temperature sensors arranged at the server nodes. The fan rotating speeds required by the nodes are determined through the various temperature sensors of the nodes of the SmartRack cabinet, the fans are directly adjusted and controlled through RBP modules, and the whole fan adjusting and control time is fundamentally saved; PWM of the fans is calculated according to the various temperature sensors, and adjusting and control are more accurate accordingly; and the fans are adjusted and controlled according to temperature information of the fans, and therefore energy consumption is reduced. By means of the method, the fans of the SmartRack cabinet are more conveniently, more flexibly and more safely adjusted and controlled, and the cooling requirements of the nodes of the SmartRack cabinet are guaranteed to the maximum degree.
Description
Technical field
The present invention relates to software and hardware regulating and control technical field of heat dissipation, be specifically related to a kind of energy-efficient SmartRack cabinet fan regulate and control method.
Background technique
Relative to traditional frame and blade server, whole machine cabinet server S martRack is the server of a class innovation form, break the mentality of designing of traditional server, take standard rack as architect, the heat radiation of traditional server and supply module, administration module are concentrated into the unified power supply of frame, fan wall and administration module, traditional server is only as the computing module of frame, this product is that cloud records center calculates and memory module, is also that conventional data centers is to cloud computation data center evolution the only way which must be passed.
SmartRack is the novel high-density Cabinet-type server based on tide sea of clouds exploitation strategem, take Customer Requirement Design as starting point, integrate and concentrate heat radiation theory, rotation speed of the fan control table is arranged on RMC(RackManagementController) in managing chip, the temperature data of each server node CPU is obtained by RBP administration module poll, and send these data to RMC, RMC obtains the maximum cpu temperature value of node by calculating, determine the rotating speed PWM of whole cabinet fan group, and by RBP administration module, entirety regulation and control are carried out to fan group.This fan regulation and controlling method obtains the maximum cpu temperature of node by RMC, then calculates fan PWM, regulates and controls whole machine cabinet fan group.First the method materially increases the fan overall regulation and control time; Secondly the method calculates fan PWM value only by cpu temperature, does not consider other factors, too unification; The method is to the regulation and control of whole machine cabinet fan entirety again, cannot determine the rotation speed of the fan that this node needs, can not reach energy-conservation object by the temperature sensor of each node.Therefore, be badly in need of proposing a kind of more reasonable, science and energy-efficient SmartRack cabinet fan regulate and control method, ensure the requirement that the node of SmartRack rack dispels the heat to greatest extent.
Summary of the invention
The technical problem to be solved in the present invention is: the invention provides a kind of energy-efficient SmartRack cabinet fan regulate and control method, take into full account with Customer Requirement Design to be starting point, integrate the design concept concentrating heat radiation, determine to regulate and control the rotation speed of the fan that this node needs separately to each fan window by the temperature sensor of each node.
The technical solution adopted in the present invention is:
A kind of energy-efficient SmartRack cabinet fan regulate and control method, described method, by rotation speed of the fan control table being arranged in the BMC process chip of each server node of SmartRack rack, being arranged at and determining by the temperature transducer of each server node (sensor) rotation speed of the fan that this node needs.
Described method specific implementation process is as follows: SmartRack rack arranges multiple RBP administration module, each administration module is responsible for n server node of its correspondence, the entering air temp that each server node BMC will obtain, core cpu temperature, internal memory temperature, PCH temperature and VR temperature data carry out calculating with the rotation speed of the fan control table being embedded in BMC inside and determine final rotation speed of the fan PWM, and this PWM is sent to the RBP administration module of its correspondence, RBP module gets the maximum value of a corresponding n fan rotating speed signals, this maximum value is sent to corresponding fan window, thus realize energy-efficient fan regulation and controlling method.
Described in the present embodiment, method operating procedure is as follows:
1) entering air temp of acquisition, core cpu temperature, internal memory temperature, PCH temperature and VR temperature data and the rotation speed of the fan control table being embedded in BMC inside carry out calculating and determine final rotation speed of the fan PWM by server node BMC;
2) PWM is sent to the RBP administration module of its correspondence by server node;
3) RBP module gets the maximum value of n fan rotating speed signals, and this maximum value is sent to corresponding fan window.
Described n is 4.
Beneficial effect of the present invention is:
The various temperature sensor of each node of SmartRack rack determines the rotation speed of the fan that this node needs, and directly passes through RBP module to fan regulation and controlling, fundamentally saves the fan overall regulation and control time; Calculate fan PWM according to many temperature Sensor, make regulation and control more accurate; According to respective temperature information, fan is regulated and controled respectively, reduce energy consumption.By the method, more convenient and flexible and safely SmartRack cabinet fan is regulated and controled, ensure the requirement of the node heat radiation of SmartRack rack to greatest extent.
