Abstract
Supporting combination decisions of virtual resources to be located in a single physical resource includes acquiring change status information indicating a change in each of a plurality of virtual resources designated as virtual resource candidates to be located in a single physical resource and determining, using a processor, whether a high correlation exists between changes in the loads of each of the plurality of virtual resources indicated in the change status information by performing statistical processing on the change status information. A suitability of locating the plurality of virtual resources in a single physical resource is determined according to the determination of whether a high correlation exists.
Claims18
A method of relocating virtual resource into a single physical resource, comprising:
- acquiring, for each of a plurality of candidate virtual resources, change status information indicating a change in a load for each of the respective plurality of candidate virtual resources;
- performing a first statistical processing on the change status information for the plurality of candidate virtual resources to determine whether a high correlation exists between changes in the loads of the plurality of candidate virtual resources;
- performing a second statistical processing on the change status information for the plurality of candidate virtual resources to determine whether a high correlation exists between load values above or below a median line in the loads of the plurality of candidate virtual resources;
- and
- locating, within the single physical resource and based upon both the first and second statistical processing, the plurality of candidate virtual resources in the single physical resource.
A computer hardware system configured to relocate virtual resource into a single physical resource, comprising:
- a hardware processor programmed to initiate the following executable operations:
- acquiring, for each of a plurality of candidate virtual resources, change status information indicating a change in a load for each of the respective plurality of candidate virtual resources;
- performing a first statistical processing on the change status information for the plurality of candidate virtual resources to determine whether a high correlation exists between changes in the loads of the plurality of candidate virtual resources;
- performing a second statistical processing on the change status information for the plurality of candidate virtual resources to determine whether a high correlation exists between load values above or below a median line in the loads of the plurality of candidate virtual resources;
- and
- locating, within the single physical resource and based upon both the first and second statistical processing, the plurality of candidate virtual resources in the single physical resource.
A computer program product for relocating virtual resource into a single physical resource, comprising:
- a computer readable storage hardware device having program code stored thereon, the program code executable by a hardware processor to perform:
- acquiring, for each of a plurality of candidate virtual resources, change status information indicating a change in a load for each of the respective plurality of candidate virtual resources;
- performing a first statistical processing on the change status information for the plurality of candidate virtual resources to determine whether a high correlation exists between changes in the loads of the plurality of candidate virtual resources;
- performing a second statistical processing on the change status information for the plurality of candidate virtual resources to determine whether a high correlation exists between load values above or below a median line in the loads of the plurality of candidate virtual resources;
- and
- locating, within the single physical resource and based upon both the first and second statistical processing, the plurality of candidate virtual resources in the single physical resource.
