Patent ID: 8151080

Claim:
A storage system having at least two storage apparatuses capable of partitioning an internal resource into logical partitions and managing the logical partitions, and which replicates data written into a primary volume of a primary storage apparatus as the replication source storage apparatus to a secondary volume of a secondary storage apparatus as the replication destination storage apparatus, comprising: a configuration information sending unit for sending configuration information of the logical partition, to which the primary volume belongs, to the secondary storage apparatus; and a logical partition setting unit for setting the configuration of the logical partition to which the secondary volume belongs based on the configuration information of the logical partition to which the primary 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 primary 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 secondary volume belongs to be smaller than the capacity of the virtual cache allocated to the logical partition to which the primary volume belongs.
