Proposed are a method and a device for managing the performance of a storage apparatus which uses a combination of different types of drive devices which mutually have different limits as its storage medium so that measures can be systematically taken against problems that may arise in the future as a result of the drive devices reaching their limit. Based on a premise of being able to tier two or more types of storage mediums which have mutually different rewriting limits and response performances and migrate data between the respective tiers according to the response performance, a performance management device estimates a decrement of a storage capacity pursuant to each of the two or more types of storage mediums reaching a rewriting limit, estimates a performance influence on the virtual volume and a timing of occurrence, and displays information related to the estimated performance influence and the timing of occurrence.

Method and device for managing performance of storage apparatus

Multiple storage apparatuses each provide a virtual logical volume composed of multiple logical pages to a host computer. A management computer determines a target logical page to which data are migrated to achieve a volume goal performance on the basis of access path information that can identify a storage apparatus that receives an I/O request in which the virtual logical volume is specified, an actual volume response performance, the volume goal performance to be attained, a page response performance of the logical page, and storage destination information that can identify a storage apparatus in which a storage area allocated to the logical page is present, and migrates data of the logical page between storage apparatuses.

Method for selecting a page for migration based on access path information and response performance information

The management system includes pair management information for managing pair groups and resource management information for managing resources allocated to the pair groups. The management system monitors data transfer latencies in asynchronous remote copy in the pair groups. In a case where data transfer latencies in a first pair group of the pair groups reach a threshold, the management system selects a first asynchronous remote copy pair from the first pair group with reference to the pair management information. The management system selects a second pair group allocated resources different from resources allocated to the first pair group as a candidate migration destination of the first asynchronous remote copy pair with reference to the resource management information.

Computer system

An information processing systemconfigured to include a plurality of storage monitoring serversthat manage performance information related to performance in a storage systemincluding a storage apparatusand a host serverthat accesses the storage apparatusand monitoring information to be monitored in the storage system. The storage monitoring serversacquire performance information and monitoring information to determine the storage monitoring serverto be responsible for managing individual performance information and individual monitoring information based on the acquired performance information and monitoring information, and transfers, according to a distribution plan determined by the storage monitoring servers, individual performance information and individual monitoring information to a storage monitoring serverresponsible for managing individual performance information and individual monitoring information.

Information processing system, and management method for storage monitoring server

The present invention provides a configuration which can realize both two objects of prevention of performance deterioration and a reduction in storage management cost and shift a volume to a storage device which supports a hierarchical pool. To provide the configuration, a storage managing system acquires access information indicating an access load to a logical volume in a storage subsystem from a device file in a host server as access information in a page unit. The storage managing system acquires, from a storage subsystem having a hierarchical pool function, information concerning the configuration and a capacity of hierarchies of the storage subsystem. A capacity of the logical volume is calculated from the number of pages and a page unit capacity indicated by the access information. The storage managing system calculates, on the basis of information concerning the capacity of the logical volume and information concerning the configuration and the capacity of the hierarchies, a configuration candidate of a hierarchical pool for allocating a storage region for storing data included in the logical volume via the hierarchical pool to a virtual logical pool and outputs the configuration candidate of the hierarchical pool.

Storage managing system, computer system, and storage managing method

The present invention provides a technique for arranging a virtual logical volume group for satisfying target response performance and realizing a cost reduction. For this purpose, in the present invention, in a storage managing system which manages a storage subsystem comprising in a pool using plural storage devices (hierarchies) having different performances and provides plural virtual logical volumes from the pool, the plural virtual logical volumes are classified into plural groups on the basis of information concerning target response performance concerning each of the plural virtual logical volumes such that each of the plural virtual logical volumes satisfies the target response performance. A new pool is allocated to each of the plural groups of the virtual logical volumes. Further, information indicating a correspondence relation between the pool and the virtual logical volumes included in the groups is generated and the information is output.
