Abstract
In a network system, a storage configuration information of a storage resource as a data storage destination and a VM resource information related to a VM as storage resource allocation destination are gathered so as to provide storage resources matching the VM characteristics to the VM. Then, based on the gathered storage configuration information, storage areas corresponding to storage tiers having different characteristics are formed, and the storage tier of the storage area allocated to the VM via the VM resource information is specified.
