DYNAMICALLY-ASSIGNED RESOURCE MANAGEMENT IN A SHARED POOL OF CONFIGURABLE COMPUTING RESOURCES
First Claim
Patent Images
1. A computer-implemented method for managing a shared pool of configurable computing resources, the method comprising:
- identifying, with respect to a target physical host of the shared pool of configurable computing resources, a resource demand value to achieve a target-physical-host-threshold-resource-utilization;
computing, with respect to a first donor physical host of the shared pool of configurable computing resources, a first resource supply value corresponding to a first set of dynamically-assigned resources on the first donor physical host, wherein the first resource supply value indicates expected achievement of a first-donor-physical-host-threshold-resource-utilization without the first set of dynamically-assigned resources;
computing, with respect to a second donor physical host of the shared pool of configurable computing resources, a second resource supply value corresponding to a second set of dynamically-assigned resources on the second donor physical host, wherein the second resource supply value indicates expected achievement of a second-donor-physical-host-threshold-resource-utilization without the second set of dynamically-assigned resources;
reclaiming a first dynamically-assigned resource from the first set of dynamically-assigned resources without exceeding the first resource supply value;
reclaiming a second dynamically-assigned resource from the second set of dynamically-assigned resources without exceeding the second resource supply value; and
distributing, to meet the resource demand value to achieve the target-physical-host-threshold-resource-utilization, the first and second dynamically-assigned resources to the target physical host.

Abstract
Disclosed aspects manage a shared pool of configurable computing resources. A resource demand value is identified for a target host. Resource supply values of dynamically-assigned resources are computed for donor hosts. Using the resource demand value and the resource supply values, dynamically-assigned resources are reclaimed from the donor hosts and distributed to the target host.
