Abstract: A storage apparatus coupled to a host device comprises a virtual volume which is a virtual logical volume configured of multiple virtual areas and a pool configured of multiple actual area groups of different performances. A controller manages pool status information which is the information showing which actual area is allocated to which virtual area and access load related to the virtual areas. A management system of the storage apparatus, with reference to the pool status information at multiple points of time from past to present and an access load threshold which is equal to or larger than 1, estimates the used capacity of each actual area group at points of time in the future, calculates the installed/removed amount of each actual area group which is the difference between the estimated used capacity and the current storage capacity, and performs the processing based on the calculated result.

Abstract: A storage management system, if the required response performance of the file is added to the access request from the host computer, compares the required response performance of the file with the response performance of the pool volume assigned to the page. If the response performance of the compared pool volume does not satisfy the required response performance, the storage management system selects a pool volume whose response performance satisfies the required response performance from the pool volumes, migrates the page to the selected pool volume, and stores the data in the page to which the pool volume is assigned.

Abstract: A management server manages resources in a cloud system having one or more servers and one or more storage subsystems. The management server is operable to: assign a category of resources to a first application of a first type, the category of resources being associated with a first template of virtualized resources, the first template being associated with threshold values and having a first cost for using the first template; monitor performance of the first template to obtain performance values for the first template; compare a first performance value of the first template with a first threshold value associated with the first template; and generate a first resource migration plan for the first application of the first type based upon a result of the comparing step. The second template is associated with a second threshold value that is greater than the first performance value. The second template has a second cost for using the second template that is less than the first cost.

Abstract: Operation of an environment that supports both host-based replication and array-based replication is realized. According to the present invention, data in the first storage area is copied first to the second storage area using an array-based replication engine. In this case, the execution result of the replication is managed using a flag from which the copy timing can be known. In addition, data in the first storage area is copied to the third storage area using a host-based replication engine, and further, data in the third storage area is copied to the fourth storage area. Then, when data in the second storage area is restored to the first storage area, data in the fourth storage area is returned to the third storage area so that the third storage area has data of the same time as the second storage area (see FIG. 12).

Abstract: A backup is completed within a backup window designated by a user. When copying data in a first storage area, which is a backup target, to a second storage area, the capacity of a medium serving as a third storage area which is sufficient to complete a backup within the backup window, is calculated based on information about a differential bitmap describing an area in the second storage area to which the relevant data is copied from the first storage area, configuration information about a storage system where the storage areas are stored, and performance information about media constituting the storage areas; and differential data is copied using the second storage area and the third storage area; and the data written to the third storage area is copied to the second storage area.

Abstract: A management computer collects a usage condition of a volume from a host computer and a storage apparatus at each site, consolidates management thereof, and prevents a volume from duplicating among applications as a copy source. This makes it possible to select a used volume in an application as a copy source without excess or deficiency and to create a copy pair configuration definition without duplication or incompatibility. If a replication environment is constructed in a large-scale storage system, the consolidated management of a usage condition of a volume collected from the host computer and the storage apparatus at each site makes it possible to create a copy pair configuration definition by a task constituted by a plurality of applications.

Abstract: A storage system comprises multiple virtual volumes (VVOLs) and multiple pools. Each pool is configured of multiple actual area groups of different performances. The storage system accesses actual areas assigned to virtual areas identified by access commands from an access source. A controller manages pool condition information which is the information showing which actual area is assigned to which virtual area and the access load related to the virtual areas. The management system of the storage system comprises management information showing a performance requirement and a performance for each VVOL. The performance of a VVOL is the performance identified with reference to the pool condition information.

Abstract: Systems and methods described herein are directed to determining a partial migration plan to execute based on a policy. In situations where the performance of the virtual volumes is insufficient, the virtual volume should be migrated to a different storage pool or have high-performance media added to its current storage pool. A management program creates several migration plans for execution, which may include more than one partial migration plans. The plans may indicate the original storage subsystem, the target storage subsystem and a number of pages. The management program selects one of the plans, and proceeds to execute the selected plan.

Abstract: Copy pair monitoring is provided for a storage system having plural host computers, at least one storage subsystem, and a management computer. The storage subsystem including volumes storing data requested by the host computer, the management computer being accessible to the host computer and the storage subsystem. The copy pair monitoring includes obtaining every piece of copy pair definition information that is stored in the host computer, removing duplicate copy pair definition information from the whole copy pair definition information obtained, and collecting the copy pair status based on the obtained copy pair definition information from which duplicate copy pair definition information has been removed. Each host computer is assigned a priority level, and, when more than one host computer includes the same copy pair, the host computer with the lowest priority obtains the copy pair information to reduce the load on the higher priority host computers.
