In a method to automate configuration of a storage virtualized environment in a system that includes one or more storage systems having array groups and one or more storage virtualizers, a management terminal selects an array group that is able to meet specifications for allocating a logical volume. The management terminal requests that the volume be allocated in the selected array group on a selected storage system. The management terminal determines the storage virtualizer that meets predetermined criteria, such as having the lightest workload, and selects an appropriate virtualizer. The management terminal requests that a virtual volume be created on the selected virtualizer, with the virtual volume mapping to the newly-allocated logical volume on the storage system and to one or more specified client hosts.
