[0003] However, the existing power consumption adjustment method is usually to adjust the power consumption at the cabinet level. By setting the peak power value of the cabinet for each cabinet that is greater than the sum of the peak power values of the servers, the above method leaves a lot of redundancy at the cabinet level. power, there is a problem of insufficient power utilization; or reduce the difference between the peak power value of the server and the peak power value of the cabinet, and use the power consumption capping technology to prevent the server from approaching the peak power at the same time and causing the power supply unit to be overcharged. The function of the above method Power consumption capping technology is to dynamically adjust the frequency of CPU work through dynamic voltage frequency adjustment technology, so as to accurately control the maximum power of the server when it is running, but this control will reduce the performance of the CPU, thereby affecting the completion time of computing tasks

The invention discloses a method and system for adjusting power consumption of a cloud data centre. One specific embodiment of the method comprises the following steps of: acquiring the total power value Pt of a cabinet column; monitoring whether the relationship between the total power value Pt and a pre-set maximum power value Pm of the cabinet column accords with a power consumption adjustment opening condition or not; if so, determining the number t of servers to be suspended according to the total power value Pt and the maximum power value Pm; and suspending t servers in the cabinet column. According to the embodiment, the power utilization rate of the cloud data centre is increased; furthermore, the completion time of a task is not influenced; therefore, the server deployment amount is increased; and the computing power of the data centre is improved.
Description
technical field [0001] The present application relates to the field of computer technology, specifically to the field of network technology, and in particular to a method and system for adjusting power consumption of a cloud data center. Background technique [0002] At present, with the development and maturity of cloud computing technology and the in-depth development of globalization, cloud data centers are constantly being improved. In order to have higher reliability and performance, the cloud data center needs to adjust the power consumption of the servers in the cloud data center to maximize the power utilization of the cloud data center. [0003] However, the existing power consumption adjustment method is usually to adjust the power consumption at the cabinet level. By setting the peak power value of the cabinet for each cabinet that is greater than the sum of the peak power values of the servers, the above method leaves a lot of redundancy at the cabinet level. ...
