Abstract: Volume deployment is optimized while adopting layering corresponding to IO density is adopted. A storage management apparatus calculates remaining IO density based on an amount of remaining IOPS and an amount of a remaining capacity in IOPS and a capacity that are providable by a node, the remaining IOPS and the remaining capacity being not allocated to any volume, controls the layers of the node based on the remaining IO density, selects a node on which a volume is to be deployed based on the difference between the IO density of a deployment target volume and the remaining IO density of the node, and determines a node having the smallest difference between the IO density of the deployment target volume and the remaining IO density of the node in the selection of the node as a deployment destination of the volume.

Abstract: A computer system comprising computers, wherein the computers include a first computer and second computers for providing resources to a business system. The business system includes a first VM capable of changing its performance by executing scale-out, and a second VMs capable of changing their performance by executing scale-up. The resource optimizing module included in the first computer is configured to: execute first processing for applying resource changing methods that are light in processing load to the active second VM and the standby second VM in a case of detecting an incident of an increase in load on the active second VM; and execute second processing for applying resource changing methods that are heavy in processing load to the active second VM and the standby second VM in a case of increasing the load on the active second VM.
