Embodiment 1

[0030] figure 1 It is a method flowchart of a data center load distribution and virtual machine migration energy-saving method provided by the first embodiment of the present invention, which includes steps 101 to 107.

[0031] Step 101, collect relevant data reflecting server resource utilization and energy efficiency ratio, and generate an overloaded server list;

[0032] This step monitors the running status and resource usage of the servers and virtual machines in the data center in real time, and regularly records the running status and resource utilization information of the servers, calculates the resource idleness of the servers and the energy efficiency ratio sequence of each server, and generates an overloaded server list ;

[0033] Step 102, select the virtual machine list VM to be migrated from the overloaded server list;

[0034] This step traverses the list of overloaded servers, selects the virtual machine with the highest priority on the list of overloaded se...

Embodiment 2

[0060] Please refer to Figure 4 , a data center load distribution and virtual machine migration energy saving system 100 provided by the second embodiment of the present invention, which includes:

[0061] Overloaded server list generation module 110, used to monitor the running status and resource usage of data center servers and virtual machines in real time, and regularly record the running status and resource utilization information of servers, and calculate the idle status of server resources and the energy efficiency ratio of each server sequence, generating a list of overloaded servers;

[0062] The first virtual machine list formation module 120 to be migrated is used for traversing the overloaded server list, selecting the virtual machine with the highest priority on the overloaded server list and requiring the smallest resource utilization rate to move out, and updating the server resource information, and then using the overloaded server The list generation module...

Abstract

The invention relates to the field of internet communication and discloses a method for distributing data center load and saving energy during virtual machine migration. The method comprises the following steps of generating an overload server list, according to the sequence that the utilization rate of optimally required resources is increased, forming an ordered list of virtual machines to be migrated, and migrating the virtual machines in the ordered list of virtual machines to be migrated to a target server; and selecting the server sm which is in an under-load state and is lowest in energy efficiency ratio, pre-distributing all the virtual machines onto the other servers by using a load distribution policy of energy efficiency perception, if pre-distribution is successful, migrating all the virtual machines on the server, and searching whether the server sm meeting condition exists or not again, and otherwise, not migrating the virtual machines and concluding an under-load server virtual machine distribution stage. According to the method provided by the invention, the low-energy-consumption load distribution and virtual machine migration can be realized, and the use ratio of a server in a data center is effectively improved.

Description

technical field [0001] The invention belongs to the field of Internet communication, and in particular relates to a data center load distribution and virtual machine migration energy-saving method and system. Background technique [0002] At present, the energy-saving methods of data centers do not consider the heterogeneity of servers in the data center. For example, the models and performances of servers purchased in different batches generally vary, which leads to the performance / power ratio of different servers. different. Therefore, the present invention considers the energy efficiency factor of the server in load distribution and virtual machine migration, and proposes a method for making the data center more energy-saving. [0003] Currently, there are existing energy-saving methods for cloud data centers based on virtual machine migration and load-aware integration. The integration process is based on the load operation characteristics, and the virtual machines or l...
