Abstract: When a first service providing device and a second service providing device located on a network have a dependent relationship, services can be disclosed and provided, with the dependent relationship held. A service utilizing device inquires of a service disclosing device regarding available services. The service disclosing device refers to service information and sends back, to the service utilizing device, an address of the first service providing device for providing a first service. The service providing device accepts a service request from the service utilizing device, refers to manageable target information, and issues a service request to the second service providing device by use of an address of the second service providing device being under non-disclosure. The second service providing device executes services and sends back requested information to the service utilizing device via the first service providing device.

Abstract: The present invention proposes a highly reliable storage system and data storage method that can prevent a data copying failure from occurring. If the allocation of a dynamically variable storage area to a primary/secondary logical volume from within that provided by a primary/secondary pool volume results in a storage area shortage in a primary pool volume, the storage system allocates an additional storage area to that primary pool volume from within the storage area provided by a physical volume, and together with this allocation, also allocates an additional storage area to all secondary pool volumes related to that primary pool volume.

Abstract: Provided is a storage controller that will not impair the operation of a storage control system even when a new storage area is added to a pool corresponding to an AOU volume. This storage controller includes a logical volume accessible by a host system; a pool associated with the logical volume and including one or more physical storage areas configuring a storage area of the logical volume; and a memory for storing attribute information showing an attribute of a physical storage area included in the pool; wherein the controller is configured to add a new physical storage area to the pool based on the attribute information.

Abstract: A data processing system in which resources of a remote copy are prevented from being wasted uselessly during a data-retention period is provided. The data processing system includes: an application server 2000, a primary storage system 4000 which stores data used by the application server in a first storage volume, a secondary storage volume 5000 which stores the copy of data stored in the primary storage system in a second storage volume, and a management server 1000 which controls the primary storage system and secondary storage system; and the primary storage system and secondary storage system are configured to include an access control table in which an access inhibited or access permitted state with respect to the first storage volume and second storage volume is stored, and a remote copy pair table in which a corresponding relation between the first storage volume and the second storage volume is stored.

Abstract: In remote data replication between storage systems, there are cases where the storage extent capacity used as the temporary storage extent in the storage system will incur waste. In a system having a management computer, a host computer, a first storage system, and a second storage system, when maintaining the replicated data of the first storage system in the second storage system via remote data replication, a change or the like in the traffic from the host computer to the first storage system is monitored, and the management computer instructs the storage system to switch the remote data replication mode in accordance with such traffic.

Abstract: In an information processing system including a computer device and a storage device storing data used by the computer device, the region in which the data is held is managed in association with a change, over the passage of time, in the performance and availability required of the data holding region. The computer device includes a storage device managing unit for managing the storage device which stores data used by the computer device. The storage device managing unit periodically monitors temporal characteristics information, and moves data, if the storage region having functional characteristics corresponding to the temporal characteristics information is different from the storage region to which the data is currently assigned.

Abstract: A computer system having a work computer, first storage systems, and second storage systems also has a network, a network routing device, and a management computer. Upon receipt of the update data from the work computer, the first storage system stores the update data in a first storage volume and stores the update data in a second storage volume until the update data is transferred to the second storage system. The management computer obtains an used capacity of the second storage volume of each of the first storage systems and controls the routing of the data by the network routing device based on the obtained used capacity to prevent the cache of each of the storage systems from being overflown.

Abstract: When a first service providing means and a second service providing means located on a network have a dependent relationship, services can be disclosed and provided, with the dependent relationship held. A service utilizing device 10 inquires of a service disclosing device 30 available services. The service disclosing device 30 refers to service information 44 and sends back, to the service utilizing device 10, an address of a service providing device 50 for providing a first service. The service providing device 50 accepts a service request from the service utilizing device 10, refers to manageable target information 65, and issues a service request to a service providing device 70 by use of an address of the service providing device 70 being under non-disclosure. The service providing device 70 executes services and sends back requested information to the service utilizing device via the service providing device 50.

Abstract: According to the prior art, it has been impossible for each program vendor to permit only specific alliance partners to use extended programs having high value-added functions.

Abstract: An information processing system has a computer, a plurality of memory devices for storing data used by a program of the computer and an allocation unit for allocating the data to a predetermined storage area for data storage. The allocation unit determines a position of a storage area for allocation on the basis of characteristic information of a memory device and volume requirement information indicative of the kind or utilization purpose of the data.

Abstract: A method for specifying an apparatus among a plurality of apparatuses composing a network. The method comprises the steps of transmitting an apparatus identifier for identifying an apparatus composing the network, receiving the apparatus identifier transmitted from the apparatus, referring to an apparatus information table indicating correlation between apparatus identifiers of the plurality of apparatuses composing the network and patterns arranged in a network configuration diagram, searching for a pattern corresponding to the apparatus identifier received, and creating a screen image indicating which of the patterns in the network configuration diagram corresponds to the searched pattern.
