Job scheduling and computer room air conditioning control method for data center energy consumption minimization

Abstract

The invention discloses a data center energy consumption minimization-oriented operation scheduling and equipment room air conditioner regulation and control method. According to the method, firstly,a data center operation distribution matrix A, a CRAC regulation and control dynamic energy consumption model PDC and a data center temperature prediction model are respectively built through historical data of a data center equipment room; the thermal coupling relation between the set temperature of refrigeration equipment and the operation temperature of IT equipment is built through the data center temperature prediction model; during operation scheduling and refrigeration equipment control, the temperature of the data center equipment room is enabled to be under a constraint condition; thePDC is minimized by using a simulated annealing algorithm through the CRAC state regulation and the integral regulation and control of the refrigeration equipment; and the overall energy consumptionof a data center is reduced. The method provided by the invention has the advantages that the overall energy consumption of the data center is the lowest, and safe operation of equipment is ensured.

Description

technical field [0001] The invention belongs to the technical field of data center job scheduling, and in particular relates to a job scheduling and computer room air-conditioning control method for data center energy consumption minimization. Background technique [0002] At present, the Power Usage Effectiveness (PUE) of large data centers is about 1.5, and there is a common problem of energy waste, and most data centers still use air cooling as the main cooling method, technologies such as liquid cooling and free cooling are still Not commonly used. Reducing data center energy consumption and improving energy efficiency are of great significance for promoting the healthy development of data centers and reducing the pressure on social power supply. [0003] At present, the main energy waste problems faced by data centers can be summed up in the following three points: [0004] (1) Due to the single consideration of the job scheduling strategy of IT equipment, the energy ...

Problems solved by technology

[0004] (1) For IT equipment, due to the single consideration of the job scheduling strategy, the energy consumption of IT equipment is wasted, and it may affect the safe operation of IT equipment

[0005] (2) In order to cope with various emergencies in the data center, the refrigeration equipment usually sets the temperature relatively low, resulting in excessive cooling

[0006] (3) Refrigeration equipment is usually based on feedback control and adjusted according to the temperature of IT equipment. Due to the characteristics of air cooling, the thermal coupling relationship of the data center is complicated, which can easily lead to the problem of cooling lag and affect the operation of IT equipment.
