摘要： The transfer rates of streams are assured if the plural streams are mixed. A disk array system required to process multiple streams from a host computer carries out recognition of the transfer rates, recognition of drive performance and a fault processing time, determines the size of a sequential buffer holding each stream, and determines the drive I/O size. Using the transfer rate and buffer size determined in these processing steps, required end times at which prefetch and destage should be terminated are found. Based on the times, the I/O priorities are determined.

摘要： In order to manage the various types of attribute information within the storage-device system, the storage-device system includes the following databases within a file-access controlling memory: a database for managing index information for managing contents of the files, and an index retrieval program, a database for managing the attribute information on the files, and a database for managing storage positions of blocks configuring a file. When the storage-device system receives an access request to a file, the utilization of these databases allows the storage-device system to make the access to the access-target file.

摘要： While a large amount of files can be intensively managed, the capacity scalability is limited by the number of magnetic disk drives and the number of magnetic tape drives which can be connected to a system, thereby failing to provide satisfactory long-term management for a large amount of information which increases more and more over time. A storage system of the present invention is designed for connection with a heterogeneous storage which can be controlled by the storage system, and creates file systems in a storage area reserved within the storage system and in a storage area provided by the heterogeneous storage.

摘要： Some disk devices used for a disk array may shorten a total active time when they are turned on 24 hours a day in comparison to a case where the disk devices are turned on only when needed. The disk device's total active time shortens when the disk device is turned on 24 hours a day and is operated continuously 24 hours a day. As a result, the disk device's operation period shortens. Such disk device is not suited for 24-hour continuous operations. The disk array capacity increases year after year. There is a trend of increasing the number of disk devices to be mounted. The power consumption for disk arrays tends to increase. A computer accessing a disk array has a disk control instruction program which allows the disk array to turn on or off specific disk devices in it. The disk array has a disk power supply control instruction reception program and a disk power supply control circuit. The disk power supply control instruction reception program receives an instruction to turn on or off disk devices from the computer. The disk power supply control circuit turns on or off a disk device corresponding to an LU specified by the computer.

摘要： A disk array includes a drive management unit, which is a program for identifying kinds of disk devices and managing different disk devices separately, and a drive management table for storing information to be utilized by the drive management unit. The disk array further includes a program for managing accumulated time of disk devices. The program includes a drive lifetime setting portion for setting lifetimes of drives, a drive start/stop portion for intentionally starting/stopping ATA disk devices, and an operation time measurement portion for measuring accumulated operation time. Since it is necessary to be conscious of difference in reliability and performance among disk devices when forming a RAID, a drive kind notification unit, which is a program for notifying of the kind of a disk device when forming the RAID, is provided.
