Abstract: A data mapping management server collects data mapping information about functions for providing virtual storage regions, and provides an administrator with a management view on which the virtual storage regions created/managed in each virtual storage region providing function can be comprehensively grasped based on the collected information. The order to migrate data with the destination after mapping alteration can be accepted on interactive views. The data mapping management server produces a procedure plan for carrying out the accepted data mapping alteration order, and presents it to the administrator. The administrator decides if this plan can be carried out. If the administrator permits this plan to be carried out, the server orders each virtual storage region providing function to migrate data and create new virtual storage regions according to the produced plan.

Abstract: A computer system is provided with a collection section for collecting load information related to an application server and a storage subsystem, a transmission section for predicting a write processing property based on the load information collected by the collection section and for transmitting the write processing property to the storage subsystem, and a write control section for controlling a write processing to a hard disk drive in the storage subsystem based on the write processing property transmitted by the transmission section. A target of the writable cache amount is set so that a write processing amount from a cache of the storage subsystem to the hard disk drive is averaged in terms of time, and the write processing to the hard disk drive is performed to satisfy the target of the writable cache amount.

Abstract: An object of remote copy can be specified in units of a file or a directory more detailed than in units of a volume. If a host computer issues a write request of a file to NASa, NASa references a source NAS of remote copy and a source directory of remote copy at each entry on a copy file table and determines whether the file to be written is an object of remote copy; if it is determined to be an object of remote copy, the file to be written is remotely copied to a target directory of remote copy of a target NAS thereof.

Abstract: A database management system (DBMS) manages a database existing in a second storage device with an access speed lower than that of a first storage device. In an execution of a query, the DBMS dynamically generates tasks two or more executable tasks in parallel. The DBMS generates task start information which is information representing a content of the execution of the task, manages the task start information, and executes a content represented by the task start information by the task. The task start information includes a data address set existing in the second storage device. The DBMS controls movement of the data address sets between the first storage device and the second storage device based on a management state of the task start information. In addition, the DBMS selects the task start information based on whether or not the data address set exists in the first storage device.

Abstract: This analysis system analyzes the behavior of a DBMS in a computer system having a computer which executes tasks in parallel and reads data from a database (DB) when executing a query. This analysis system acquires the number of selected rows corresponding to a key value of an index key used in the query, and calculates a model-based predicted degree of processing parallelism of the processing corresponding to the query. The system acquires, from the storage device, event information on an input-output event with respect to the storage medium when the processing corresponding to the query is executed actually, calculates a measured degree of processing parallelism when the processing corresponding to the query is executed actually, based on the event information, and displays information based on the model-based predicted degree of processing parallelism and the measured degree of processing parallelism.
