US 2010/0250734 A1 · SERVER REASSIGNMENT SUPPORT SYSTEM AND SERVER REASSIGNMENT SUPPORT METHOD

Abstract

A server reassignment support system has a storage device, a deallocated state estimation module and an allocation plan generation module. Stored in the storage device are an operation data indicating operation status of a plurality of physical servers and a plurality of virtual servers and a capacity data indicating resource capacity of each of the plurality of physical servers. The deallocated state estimation module refers to the operation data and the capacity data to extract an overloaded server from the plurality of physical servers, load of the overloaded server exceeding a threshold value depending on the resource capacity. Further, the deallocated state estimation module estimates a state in which at least part of virtual servers allocated to the overloaded server is deallocated as a deallocated server among the plurality of virtual servers. The allocation plan generation module generates an allocation plan for the deallocated server based on the estimated state.

Claims21

Dependent claims

A server reassignment support system that supports reassignment of a plurality of virtual servers allocated to a plurality of physical servers, comprising:

a storage device in which an operation data indicating operation status of said plurality of physical servers and said plurality of virtual servers and a capacity data indicating resource capacity of each of said plurality of physical servers are stored;
a deallocated state estimation module configured to refer to said operation data and said capacity data to extract an overloaded server from said plurality of physical servers, load of said overloaded server exceeding a threshold value depending on said resource capacity, and to estimate a state in which at least part of virtual servers allocated to said overloaded server is deallocated as a deallocated server among said plurality of virtual servers;
and
an allocation plan generation module configured to generate an allocation plan for said deallocated server based on said estimated state.

1 more element

A server reassignment support method for supporting, by using a computer, reassignment of a plurality of virtual servers allocated to a plurality of physical servers, comprising:

reading an operation data indicating operation status of said plurality of physical servers and said plurality of virtual servers from a storage device;
reading a capacity data indicating resource capacity of each of said plurality of physical servers from a storage device;
extracting an overloaded server from said plurality of physical servers, load of said overloaded server exceeding a threshold value depending on said resource capacity, with reference to said operation data and said capacity data;
estimating a state in which at least part of virtual servers allocated to said overloaded server is deallocated as a deallocated server among said plurality of virtual servers;
and
generating an allocation plan for said deallocated server based on said estimated state.
