摘要： A storage system includes a plurality of disk apparatuses configuring a plurality of RAID groups, a spare disk apparatus, and a controller. The controller is adapted to copy data stored in a disk apparatus, whose error count exceeds a first threshold, to the spare disk apparatus. If an error count of a disk apparatus included in a RAID group exceeds a second threshold which is lower than the first threshold, the controller is adapted to check error counts of other disk apparatuses included in the same RAID group. If any of the error counts of the other disk apparatuses included in the same RAID group exceeds the second threshold, the controller is adapted to change the first value of the first disk apparatus and the other disk apparatuses included in the same RAID group.

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.
摘要翻译：与仅在需要时才开启磁盘设备的情况相比，用于磁盘阵列的某些磁盘设备每天24小时都可能会缩短总的活动时间。当磁盘设备每天24小时开启时，磁盘设备的总活动时间缩短，每天24小时不间断运行。因此，磁盘设备的运行时间缩短。这种磁盘设备不适用于24小时连续操作。磁盘阵列容量逐年增加。存在要安装的磁盘设备数量增加的趋势。磁盘阵列的功耗趋于增加。访问磁盘阵列的计算机具有磁盘控制指令程序，该程序允许磁盘阵列打开或关闭其中的特定磁盘设备。磁盘阵列具有磁盘电源控制指令接收程序和磁盘电源控制电路。磁盘电源控制指令接收程序接收从计算机接通或关闭磁盘设备的指令。磁盘电源控制电路打开或关闭与计算机指定的LU对应的磁盘设备。

摘要： A storage system having a plurality of disk controllers for accepting computer access through a SAN, and a plurality of file servers for accepting computer access through a LAN. The disk controllers and file servers are connected through a connection unit to a plurality of disk drive units in a disk pool. A disk pool management unit manages the relationships between the disk controllers and file servers and the disk drive units used by the respective disk controllers and file servers, and sends information identifying the usable disk drive units to the respective disk controllers and file servers. The disk controllers and file servers use the disk drive units based on the received usable disk information.
