Abstract: When creating a storage pool with external volumes, it is not possible to put together the volumes that have the same level of reliability if consideration is only given to the physical attributes of such volumes. Further, the reliability demanded between a host computer and a storage apparatus does not necessarily match the reliability between storage apparatuses. When creating a storage pool in the data processing system of this invention, not only is consideration given to the characteristics of the physical disks themselves, consideration is also given to the connection status of the backend network between a storage apparatus and a switch loaded with external storage function, and an external storage apparatus. What is more, volumes are allocated to a host machine after said system considers both the redundancy of a backend network of between storage apparatuses and that of a network path between the host machine and storage apparatus.

Abstract: This invention provides, when optimizing a configuration of a storage system using a pool, an optimal configuration while ensuring a policy set by an administrator, the policy concerning a power saving performance, a response performance, or the like. The management computer sets, according to the set policy, priorities to volumes held by a storage subsystem, and reserves volumes satisfying the capacity of the pool, in descending order of the priority. Only some of the reserved volumes are registered for the pool in descending order of the priority. At this time, it can be guaranteed that a host computer makes no access to the volumes which have not been registered for the pool, and therefore the sleep state is set to physical drives forming the volumes or to a controller controlling the physical drives.

The management apparatus includes a storage unit that stores configuration information, performance information and threshold values used for performance management regarding the devices in the first and second storage systems connected to the management apparatus; and a setting section that adopts and sets, when internal management information and data are copied from the first storage system to the second storage system, threshold values assigned to the devices in the first storage system to the devices in the second storage systems.

Abstract: The present invention provides a high-performance storage access environment to a user who moves around a wide area, while increasing the fault resistance of the system. A plurality of network storages (volumes) is assigned to the user. Then, at the occasion of logging in to a volume by the user, the volume that can be accessed with high performance from a position he made access is located. Addresses at a computer with which user makes access are associated with addresses of the volumes provided by a storage device in advance in an assigned volume management table so as to increase access performance. Then, a management server performs control so that the address of the volume associated with the user access position is returned as a response, at the time of logging in.

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.

Abstract: This invention provides a system including a computer and a storage-subsystem comprising at least either a first storage area for storing data sent from the computer or a second storage area to be associated with the first storage area, for storing replicated data of data stored in the first storage area. This system includes a replication processing status referral unit for referring to a replication processing status of data of the first storage area and the second storage area to be associated, and an output unit for outputting first performance information concerning data I/O stored in the first storage area, and outputting second performance information concerning data I/O stored in the second storage area together with the first performance information when the replicated data is being subject to replication processing from the first storage area to the second storage area as a result of referring to the replication processing status.

Abstract: Access to the physical disks is differentiated as access from a host computer, and access based on processing (data migration processing, copy processing) for storage management. Whether to switch the state of the physical disks from a normal power consumption mode to a power saving mode is determined according to the access from the host computer after the access based on processing for storage management is complete, and the state of the physical disks are switched from the normal power consumption mode to the power saving mode based on the determination result.

Abstract: A burden placed on an administrator in creating a volume is reduced. An evaluation hint value and a performance hint value are employed as hint values for each hint. The evaluation hint value is determined by the administrator considering a service usage and the like of the service server 1 to which the volume is allocated. The performance hint value is used to determine a performance and a setting of the volume to be created in the storage system 3. The management server 2 has a conversion table indicating a correspondence between the evaluation hint value defined considering the hardware configuration and the performance hint value, with respect to each storage system 3. The management server 2 converts the evaluation hint value designated by the administrator to a performance hint value, by use of the conversion table associated with the storage system to which the volume is to be created, and the management server creates the volume in the storage system 3 according to the performance value.
