The power consumption control method of machine cabinet cluster system
Technical field
The present invention relates to the rack cluster field, relate in particular to a kind of power consumption control method of machine cabinet cluster system.
Background technology
At present, in calculating machine cabinet cluster system, usually can deposit more rack.These racks can produce larger heat when work, excess Temperature is the ubiquitous problem of data center in the server cabinet.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 machine cabinet cluster system or directly to machine cabinet cluster system discharging cold air, owing to loading in the machine cabinet cluster system spatially and be pockety on the time, the distribution that causes temperature also is inhomogeneous, and focus and cold spot are arranged.The heat dissipation design of existing machine cabinet cluster system generally is based on thermodynamics stable state system carries out, and has caused a large amount of energy and the waste of resource.Therefore, by setting up the thermodynamics heat dissipation 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 machine cabinet cluster system is simulated at present, thereby determine refrigeration modes.Usually the analog form that adopts mainly contains following two kinds:
(1) Finite Element Method: adopt distributed model.The 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, then provide the external condition simulation of dispelling the heat, afterwards, need to carry out a large amount of computings by computing machine, every bit is simulated, and the advantage of the 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 large, when simulating in conjunction with the thermodynamic behaviour of each rack, calculation scale and time can increase several orders of magnitude.
(2) experimental formula method: use centralized model.Centralized model namely represents the parts of being concerned about with an abstract point for distributed model, this point has the numerical value of the physical parameters such as temperature, power, represents whole parts; Parts have volume, and its inner temperature may be different at diverse location, and this abstract point does not have volume, only has a temperature, represents whole parts.The model of setting up like this is just fairly simple.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 accordingly 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 larger, be only suitable for the object of geometric configuration comparison rule, especially in complicated system, owing to will use a plurality of experimental formulas, result's precision can be subject to the obvious impact of accumulated error, can not obtain good simulate effect.

Yet rack and cooling device have accounted for the share more than 80% altogether in the general power in machine cabinet cluster 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 machine cabinet cluster system.Thereby the defective of the method is after definite machine cabinet cluster system temperature, can not be in time, effectively machine cabinet cluster system is carried out power consumption control and distribution.In addition, because can not be in time, effectively machine cabinet cluster system is carried out power consumption control and distribution, so can cause owing to excess Temperature produces negative consequence, 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.
