Abstract

A managing computer (manager) manages replication of data areas inside a storage or among storages. A storage volume management module of the manager manages policy of the volume and its properties. When replication of a volume is set, a volume of a replication destination appropriate for a volume of a replication source is generated using the policy and the properties to form a replication pair. A route management module of the manager and its volume management module bring the policy and the properties of the volumes, and the policies and conditions of lines into conformity with one another. When any fault occurs in a line route used for data transfer during replication of the volume, a separate line route is utilized, and a fault countermeasure is taken for replication of the volumes in accordance with the policy and properties of the volumes.

Claims

1-17. -17. (canceled)

18. A storage system coupled to a computer, comprising:

a plurality of storage devices comprising a plurality of volumes; and

a managing computer coupled to the plurality of storage devices having capacity information representing volume capacities of the plurality of volumes and read/write information representing read/write frequencies of the plurality of volumes;

wherein the management computer receives a request designating a copy source volume among the plurality of volumes, selecting a copy destination volume, which capacity is the same or larger than a capacity of the copy source volume, from the plurality of volumes based on the capacity information,

wherein a copy source storage device among the plurality of storage devices corresponding to the copy source volume forms a copy pair between the copy source volume and the copy destination volume, and copies the contents of the copy source volume to the copy destination volume, and

wherein the copy source storage device releases the copy pair after the copy, according to a part of the read/write information corresponding to the copy source volume.

19. A storage system according to claim 18, wherein the copy destination volume is included in a copy destination storage device, which is one of the plurality of storage devices, and wherein the selection of the copy destination volume is based on a distance between the copy source storage device and the copy destination storage device.

20. A storage system according to claim 18, wherein the read/write information includes a plurality of values for representing the read/write frequencies of the plurality of volumes, each of the plurality of values corresponding to a read/write frequency of each of the plurality of volumes.

21. A storage system according to claim 20, wherein the part of the read/write information corresponding to the copy source volume is one of the plurality of values corresponding to the copy source volume.
