    摘要： A database system includes a center server and local servers. The center server includes a replication requesting unit, a data consolidating unit including a center DB freeze requesting unit and a center DB freeze release requesting unit, a replication source managing table and a data consolidation completion notifying unit. Each of the local servers includes a local DB freeze requesting unit, a remote volume split requesting unit, a remote volume split completion notifying unit and a local DB freeze release requesting unit. The center server permits replications of local DB's in local storage subsystems to be created in the center storage subsystem and accesses shadow images of the replications to give a consolidated access to the plurality of local DB's.

    摘要： Provided is a computer system including: a computer running as a DB server; a storage system including a plurality of disk drives for storing data; and a management module, in which: at least one of the plurality of disk drives stores data of a DB schema written by the computer; the management module specifies the DB schema to be accessed based on a received query, transmits, to the storage system, an instruction to copy at least a portion of the data of the specified DB schema from the disk drive to a memory, and transmits, to the storage system, an instruction to control an rpm of the disk drive that stores the data of the specified DB schema; and the storage system controls the rpm of the disk drive based on the instruction. Accordingly, power consumption of the storage system can be reduced even if installed disks increase in number.

    摘要： A disk rotation control part for controlling the rotations of a plurality of disk devices is provided. The configuration is such that a disk of a disk device for which an access will not be generated is rotated at a second rate of speed, which is faster than 0, and slower than a first rate of speed, which is the rotation speed at access time. DB management information comprises information denoting which DB schema inside a DB is stored in which location. The disk rotation control part, based on a query plan of a query received by the DBMS, and DB management information, specifies the storage location of a DB schema to be accessed when this query is processed, and rotates a disk of the disk device comprising the specified storage location at a first rate of speed.

    摘要： A database (DB) server in which a database management system (DBMS) operates and a prefetch server connected to a storage device storing DB data are provided with an acquiring unit for acquiring information on a storage location on the storage device of a DB schema managed by the DBMS, information on DB processing executed by the DBMS, and information on an access to DB data made when the DBMS executes the DB processing, from the DB server, a predictor for predicting data to be read out on the basis of the acquired information, and a prefetch instructing unit for providing the storage device with an instruction to prefetch the corresponding data. Having received the prefetch instruction, the storage device reads out specified data onto a cache memory.
