The power consumption control method of rack group system
Technical field
The present invention relates to the rack cluster field, relate in particular to a kind of power consumption control method of rack group system.
Background technology
At present, in calculating the rack group system, can deposit more rack usually.These racks can produce bigger heat when work, the server machine in-cabinet temperature is too high to be the ubiquitous problem of data center.For the normal operation that guarantees rack and the serviceable life of rack, rack is dispelled the heat and freezes is the previous commonplace measure of order.Yet, in energy shortage more and more serious today, carry out the research of the aspect of cluster power consumption control and management, have very high society and economic worth to saving electric power resource.
Usually, the mode of heat radiation mainly is to install an air-conditioner in the rack group system or directly to rack group system discharging cold air, owing to load in the rack group system spatially and be pockety on the time, the distribution that causes temperature also is uneven, and focus and cold spot are arranged.The heat dissipation design of existing rack group system is based on generally that thermodynamics stable state system carries out, and has caused a large amount of energy and the waste of resource.Therefore, by setting up thermodynamics heat radiation model, set up the real-time monitoring of cluster power consumption and the mechanism that power consumption is distributed, accurately freezing is one of present research emphasis.
Mainly be that the radiating mode of rack group system is simulated at present, thereby determine refrigeration modes.Usually the analog form that is adopted mainly contains following two kinds:
(1) Finite Element Method: adopt distributed model.This method is set up the model of object in computing machine, it is divided into hundreds of thousands even junior unit up to a million, provide the external condition simulation of dispelling the heat then, afterwards, need carry out a large amount of computings by computing machine, every bit is simulated, and the advantage of this method is that degree of accuracy is higher as a result, and error is generally about 10%.But because the calculated amount in simulation process is very big, when simulating in conjunction with the thermodynamic behaviour of each rack, calculating scale and time can increase several magnitude.
(2) experimental formula method: use centralized model.Centralized model is just represented the parts of being concerned about with an abstract point for distributed model, this point has the numerical value of physical parameters such as temperature, power, represents whole parts; Parts have volume, and its temperature inside may be different at diverse location, and this abstract point does not have volume, has only a temperature, represents whole parts.The model of Jian Liing is just fairly simple like this.Because most of lattice points are very little with the temperature difference of contiguous lattice point in the Finite Element Method, so carried out a large amount of unnecessary calculating, in order to address this problem, the experimental formula method is according to the material of object, geometric configuration, simulate with heat exchange pattern, can simplify heat transfer process, and when simulation, can replace distributed model with centralized model, the experimental formula of having summed up in view of the above with reference to forefathers, can rule of thumb adjust heat-conduction coefficient, its advantage is the computation process simple and fast, shortcoming is that error is bigger, the object of only suitable geometric configuration comparison rule is especially in complicated system, owing to will use a plurality of experimental formulas, result's precision can be subjected to the obvious influence of accumulated error, can not obtain good simulate effect.
A kind of computer to dissipate heat analogy method is provided in the Chinese patent application of publication number for CN101650760A.This computer to dissipate heat analogy method comprises: each rack in the machine room is carried out the real-time monitoring and the analysis of power, determine that according to monitored results the focus at each rack place distributes; Utilize centralized model to determine the temperature of each rack internal part,, utilize Finite Element Method to determine the temperature of each rack place focus according to the temperature of each rack internal part, and the temperature of definite machine room.The calculated amount that said method has solved the existence of cooling machine cabinet simulation mechanism is big, degree of accuracy is low and the problem of the comparatively serious power consumption that lags behind.
Yet rack and cooling device have accounted for the share more than 80% altogether in the general power in the rack group system, and the heat that produces when the function of cooling device is moved with server is closely related.In said method, only relate to the temperature of determining the rack group system.Thereby the defective of this method is after definite rack group system temperature, can not be in time, effectively the rack group system is carried out power consumption control and distribution.In addition, because can not be in time, effectively the rack group system is carried out power consumption control and distribution, so can cause and produce negative consequence owing to temperature is too high, and the situation of all taking the mode of high-power refrigeration plant to dispel the heat for excessive temperature and higher temperature can appear, can cause power wastage like this.

Step S102: the rack in the rack group system is carried out the real-time monitoring of power, determine focus distributed intelligence in the rack according to monitored results, wherein, the focus distributed intelligence comprises the quantity and the positional information of focus.For high-power rack, can be considered a plurality of focuses (quantity that is to say focus is by the power decision).Under default situations, these focuses are in the inner evenly distribution of rack.Under the situation that can accurately know each regional power in the rack (for example device power supply (DPS) can provide power information accurately), focus is according to the position distribution of equipment in rack, but a zone can only be represented with a focus at the most.Thus, by rack being divided into a plurality of zones, and the zone is corresponding with focus, can more easily determine the quantity and the positional information of focus, thereby improve the efficient of rack group system power consumption control process.
Step S104: according to determined focus distributed intelligence, determine the group system temperature, to obtain and the corresponding rack group system of rack group system temperature parameter.Fig. 5 shows the flow process according to the acquisition rack group system temperature parameter method of the embodiment of the invention.As shown in Figure 5, can specifically obtain rack group system temperature parameter: step S502 by the following method:, utilize centralized model to determine the temperature of rack interior zone according to determined focus distributed intelligence.Wherein, the focus distributed intelligence comprise focus quantity and with the positional information of the corresponding rack interior zone of each focus.Step S504: according to the temperature of rack interior zone, utilize Finite Element Method to determine the temperature of rack, to determine rack group system temperature.Step S506: determine rack group system temperature parameter.Rack group system temperature parameter comprises rack group system temperature changing speed, rack group system range of temperature and rack group system temperature real time temperature value.It will be understood by those skilled in the art that this rack group system temperature parameter is not limited to the top content that is limited, and can also comprise multiple other parameter.
Step S106: judge whether rack group system temperature parameter reaches the preset temperature parameter.If reached, then get back to step S102; If do not reach, then need to carry out step S108.
Step S108:, adjust for the power consumption of rack group system if rack group system temperature parameter does not reach the preset temperature parameter.Adjustment process has comprised dual mode, is directed to the power consumption of the equipment that moves in the power consumption of refrigeration plant and the rack respectively.
Below, will be by the mode of example, the multiple mode that the power consumption of rack group system is adjusted is described in detail.
