Abstract: A method for application migrating from a first cluster to a second cluster. The method may include detecting application migration request from the first cluster to the second cluster for performing application migration; identifying first volumes associated with the first cluster that are used by the application; establishing data copying from the first volumes of a first storage device associated with the first cluster to second volumes of a second storage device associated with the second cluster; determining if a copy condition is met based on the data copying; for meeting the copy condition, stopping the application on the first cluster; flushing uncopied data from the first volumes to the second volumes; determining whether the flushing of the uncopied data is completed; and for the flushing of the uncopied data being completed, deploying the application on the second cluster.

Abstract: To quickly and appropriately adjust a performance of a storage system. A storage configuration optimization device for managing a storage system including one or more storages implemented by a plurality of SDS nodes includes a virtual CPU. The virtual CPU is configured to receive a request for an execution period and a necessary performance of a project using the storage system, and select, based on consumption information and performance information of a resource of the storage system, one or more change patterns satisfying the request for the execution period and the necessary performance from among a plurality of change patterns indicating configuration changes of the storage system.

Abstract: A storage-based migration is performed in a VVOL environment. A migration processing unit generates a migration group in which a virtual volume to be migrated, a protocol endpoint related to the virtual volume, and a storage container that cuts out the virtual volume are grouped, and migrates the migration group to a storage node; and a configuration changing unit configures, based on information of the migration group transmitted from the storage node, a protocol endpoint, a virtual volume, and a storage container on a storage node which are the same as the protocol endpoint, the virtual volume, and the storage container configured on the storage node.

Abstract: To detect an abnormality of logical and physical addresses, a storage device includes: plural drives each having a storage medium configuring a logical volume provided to a host device; a front end I/F that receives an I/O request including a logical address for identifying a logical storage area of the logical volume, and user data from the host computer; a processor that controls conversion from the logical address into the physical address for identifying a physical storage area of the storage medium; and a back end I/F that controls write/read of user data with respect to the drives based on the physical address. In the drives, data where a first guarantee code obtained based on the physical address and the logical address corresponding to the physical address is added to the user data is stored in the physical storage area designated by the physical address of the storage medium.

Abstract: An object of the invention is to quickly and appropriately adjust performance of a storage system. Provided is a storage management system including: a storage system including a plurality of storage nodes; and a management device. The storage node includes a storage device and an instance to which a resource is virtually allocated and that controls access to the storage device. The storage management system further includes an instance management node configured to manage the instance of the storage node. The management device is configured to determine whether a configuration of the resource allocated to the instance of the storage node needs to be changed, and cause the instance management node to change the configuration of the resource allocated to the instance when the configuration of the resource needs to be changed.

Abstract: A processor of each node of a storage system executes rebalancing to transfer a volume between pool volumes for the node in such a way as to equalize throughput of a data input/output process and/or data capacities between the pool volumes making up the pool. When a plurality of external volumes are transferred to a node in the storage system, the storage management apparatus determines a transfer destination node for the volumes and order of transferring the volumes and executes volume transfer in such a way as to equalize throughput of the data input/output process and/or data capacities between the pool volumes making up the pool after completion of or during the volume transfer.

Abstract: The present invention is directed to realize a QoS function in the unit of a virtual volume group existing over a plurality of storage apparatuses. A management system of a storage system forms a virtual volume group by using a plurality of volumes provided by a plurality of storage apparatuses. In the virtual volume group, a QoS setting value including a data input/output amount is set. IO processing ability provided from each of the volumes to the virtual volume group is set so as to satisfy the QoS setting value. The management system sets the IC processing ability provided from each of the volumes to the virtual volume group on the basis of operation information of each of the volumes.

Abstract: The computer system executes environment classification of classifying a plurality of subsystems, each being a physical or virtual computer system, into one or more environment groups being one or more groups. The computer system stores classification result data which is data representing a relationship between the environment group and the subsystems belonging to the environment group. The computer system selects, from the classification result data, the environment group to which the subsystem having undergone a problem belongs. The computer system generates a reproduction subsystem which is a virtual subsystem virtually reproducing the subsystem for each of the subsystems belonging to the selected classification result group. The computer system applies the countermeasure to at least one reproduction subsystem for the purpose of verifying the countermeasure for the problem.
