Abstract
An assigning system and an assigning method are provided for assigning a storage device or a unitary logical unit of the storage device. A VLU-LU correspondence table is provided which shows a correspondence between virtual logical units (VLU) virtually set in a host computer and logical units (LU) of a plurality of storage devices connected to a network. This table stores evaluation items of each storage device such as a delay time and an access frequency. An evaluation unit calculates an evaluation value of each evaluation item in the table, and a unitary logical unit of the storage is assigned in accordance with the evaluation value.
