摘要： Provided is a storage device which partitions data from a host into multiple partitioned data and distributes, encrypts and stores them together with a parity to and in multiple memory mediums. This storage device executes processing of restoring the partitioned data or the parity stored in a memory medium to be subject to encryption re-key based on decrypted data of the partitioned data or the parity stored in each memory medium other than the memory medium to be subject to encryption re-key among the multiple memory mediums, storing the restored partitioned data or the parity in a backup memory medium while encrypting the restored partitioned data or the parity with a new encryption key, and thereafter interchanging the backup memory medium and the memory medium to be subject to encryption re-key so that the backup memory medium will be a memory medium configuring the parity group and the memory medium to be subject to encryption re-key will be the backup memory medium.

摘要： A storage system allocates a data storage area in response to an access request from a first computer if the capacity of a first physical storage device configuring a first logical storage area, provided to the first computer, is equal to or lower than a predetermined threshold. The storage system associates the first logical storage area with another physical storage device, which is different from the first physical storage device associated with a second logical storage area provided to the first computer and a second computer, and allocates a data storage area from the another physical storage device if the capacity of the first physical storage device associated with the first logical storage area exceeds the predetermined threshold.

摘要： The load of managing a storage system is lessened. In a storage system where multiple logical volumes are included in a logical volume group and a copy of the logical volume group is made in a pool area different from the one to which the logical volume group belongs, a management computer adds to the pool area capacity when the capacity of a pool area exceeds a predetermined threshold. When the pool area includes multiple logical volume groups, the management computer requests the storage system to create a pool area for each of the logical volume groups and to create the logical volume groups respectively for the created pool areas. When the pool area includes one logical volume group, the management computer requests the storage system to make the capacity of the pool area coincide with the capacity of a pool area to which the logical volume group is copied.

摘要： In order to manage and operate Pool created in storage system A and a virtual volume using Pool in storage system B, it is required to copy the virtual volume of storage system A into a virtual volume of storage system B and new storage regions for copy of virtual volume into storage system B are needed. Storage system B acquires configuration information of Pool and a virtual volume of storage system A and inputs a logical volume included in Pool of storage system A to storage system B based on the acquired configuration information. Storage system B transforms the acquired configuration information for use in storage system B and creates Pool and a virtual volume from the input logical volume based on the transformed configuration information.

摘要： 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.
