Abstract: Exemplary embodiments provide data volume migration with migration log confirmation in which the same data volume identifier is used beyond migration for a data volume. In one embodiment, data is migrated to or from a data volume in a data storage area of a storage apparatus. The data being migrated is identified by a data volume identifier which remains unchanged after migration. The same data volume identifier is used in both the source data volume and the destination data volume. The storage apparatus stores migration log information of the data volume. The migration log information includes the data volume identifier, a source name of the source data volume of the data being migrated, a destination name of the destination data volume of the data being migrated, and log information on any prior migration of the data being migrated.

Abstract: Systems for backing up the data of an IT system by utilizing server or storage virtualization technology to create and move logical IT infrastructures dynamically. A virtualized IT system provides a server resource pool and a storage resource pool composed from multiple physical devices either within a datacenter or a globally located plurality of datacenters. The virtual server and the storage volume provisioned from those pools will be paired to form the virtual infrastructure. In other words, the virtual infrastructure becomes a logical IT environment build with the required computing and storage resources needed in order to execute specific applications. The virtual infrastructure can also be migrated within/among datacenter sites.

Abstract: Embodiments of the invention provide a method and apparatus for storage subsystem migration without re-configuration of the I/O path. In one embodiment, a computer system comprises a first storage subsystem, a second storage subsystem, and a computer device connected via a network. The first storage subsystem has a first port name for a first port through which a first volume in the first storage subsystem has I/O connection with the computer device. The second storage subsystem defines a first virtual volume which is associated with the first volume, and a first virtual port having a first virtual port name that is identical to the first port name. After activation of the first virtual port, the computer device switches I/O connection for the first volume from the first storage subsystem to the second storage subsystem via the network using the first virtual port name on the second storage subsystem.

Abstract: In a storage system having a function of acquiring update history information in correspondence with a write operation from a host, update data according to the amount of data written will become enormous. Thus, there is a problem in that long-term backup and data management using update history information is not possible. A management computer defines a service level according to time progress of data, and stores and manages update history information according to the service level in the respective stages. The management computer manages the update history information, and partially migrates update data from a certain storage system to another storage system according to the service level required in the data. The management computer also restores data in the storage system to which the update data was migrated.

Abstract: System and method for agile deployment of servers. The system includes one or more storage subsystems, a host computer and a storage management server or general severs together with a system management server. A system administrator or a storage supplier preliminarily installs an application package on a server. The application package may include an operating system, programs, libraries, configuration data and initial data. When the system requires a new physical or virtual server, the system administrator replicates the installed application package and conducts the new server runs with the replicated application package. Operation sequences are provided for order of copying of the application package between the management servers and the storage subsystems. Change in the data from an initial state may be stored instead of the complete data.

Abstract: Exemplary embodiments establish durable partitions that are unified across storage systems and storage server computers. The partitions provide independent name spaces and are able to maintain specified services and conditions regardless of operations taking place in other partitions, and regardless of configuration changes in the information system. A management computer manages and assigns resources and functions provided by storage server computers and storage systems to each partition. By using the assigned resources, a partition is able to provide storage and other services to users and applications on host computers. When a configuration change occurs, such as addition or deletion of equipment, the management computer performs reassignment of resources, manages migration of services and/or data, and otherwise maintains the functionality of the partition for the user or application.

Abstract: A first storage system includes a first storage area for storing data written by a computer. A second storage system includes a second storage area to which the data stored in the first storage area migrates. A third storage system includes a virtual storage area corresponding to the second storage area. An access request to the virtual storage area is converted into an access request to the second storage area to be issued. A management computer transmits, to the third storage system, an instruction to migrate the data of the second storage area to a third storage area of the third storage system based on a determination result between a value of the data migrated to the second storage area and a predetermined threshold value.

Abstract: 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.

Abstract: To migrate a configuration that an old storage device has to a new storage device. A new storage device obtains a configuration of an old storage device, by using a migration manager, and prepares a logical volume definition of the new storage device based on a logical volume definition in the configuration. Also, based a cache allocation definition in the configuration and cache capacity of the new storage device, a cache allocation definition of the new storage device is prepared. Further, based on a port bandwidth allocation definition in the configuration and bandwidth capacity of a port of the new storage device, a port bandwidth allocation definition of the new storage device is prepared. The prepared logical volume definition, cache allocation definition and port bandwidth allocation definition are set up in a configuration of the new storage device.
