Abstract:
1. A storage system including a first storage apparatus and a second storage apparatus capable of partitioning an internal resource into logical partitions and managing the logical partitions, and which replicates data written into a first volume of the first storage apparatus to a second volume of the second storage apparatus, comprising: a configuration information sending unit for sending configuration information of the logical partition, to which the first volume belongs, to the second storage apparatus; and a logical partition setting unit for setting the configuration of the logical partition to which the second volume belongs based on the configuration information of the logical partition to which the first volume belongs sent from the configuration information sending unit; wherein the configuration information of the logical partition includes the capacity of a virtual cache, which is a virtual cache memory allocated to the logical partition to which the first volume belongs; and wherein the logical partition setting unit initially sets the capacity of the virtual cache to be allocated to the logical partition to which the second volume belongs to be smaller than the capacity of the virtual cache allocated to the logical partition to which the first volume belongs.
