Problems solved by technology

[0005] On the contrary, if the load generated by multiple virtual servers to be deployed is too high compared with the sum of the performance obtained by using one or more physical servers in operation, there will be no processing margin in the physical servers in operation, and it will not be possible to cope with emergencies. There is a possibility of delays during processing due to a sudden increase in virtual server load

Embodiment Construction

[0034] (1) System configuration

[0035] Hereinafter, for the overall configuration of the network system (hereinafter simply referred to as "system") including the management server of the embodiment, refer to figure 1 Be explained.

[0036] like figure 1 As shown, in this system, the management server 2, the management terminal 3, and the managed server group 4 are connected via a network. In this system, the management server 2 controls such that one or more virtual servers are allocated to each physical server in the managed server group 4 . At this time, it is desired to perform efficient virtual server placement from the viewpoint of the processing capability of the physical server and its power consumption.

[0037] like figure 1 As shown, the managed server group 4 includes a plurality of virtual servers (indicated by "V" in the figure.) and a plurality of physical servers (indicated by "P" in the figure.), which become managed by the management server 2 via the ne...

Abstract

When a plurality of virtual servers is distributed to a plurality of physical servers, efficient distribution is performed from the perspectives of the processing capacities of the physical servers and power consumption thereof. First, a future second load of each virtual server is predicted based on a first load during the specified period until the current time of each of the plurality of virtual servers. Next, the schedule is determined to distribute the plurality of virtual servers to the plurality of physical servers based on the second load of each virtual server so that the one second load or the sum of the second loads of a plurality of virtual servers distributed to the physical servers enters the specified ratio ranges for the processing capacities of the physical servers. Furthermore, the distribution is indicated (execution of redistribution) in accordance with the schedule.

Description

technical field [0001] The present invention relates to a technology of virtual computing for operating a plurality of virtual servers on a plurality of physical servers, and more specifically, relates to a plan for placing virtual servers on physical servers. Background technique [0002] With the development of virtual server technology in recent years, a technology (live migration) of operating a plurality of virtual servers on a physical server and moving the virtual servers between different physical servers without changing the operating state has been applied. Regarding migration, it is mentioned in Patent Document 1, for example. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2006-244481. [0004] However, when the load generated by the plurality of virtual servers to be placed is too low compared with the sum of the performance obtained by using one or more physical servers in operation, the physical servers may run uselessly. That is, in t...
