    摘要: A reliable remote copy system is provided at low costs. The remote copy system includes a first storage system connected to a first upper level computing system to transmit or receive data to or from the first upper level computing system; a second storage system connected to the first storage system to receive data from the first storage system; and a third storage system connected to the second storage system to receive data from the second storage system and connected to a second upper level computing system to transmit or receive data to or from the second upper level computing system. Therefore, failover can be made from the first upper level computing system to the second upper level computing system. As a result, the upper level computing system connected to the second storage system is not required, and an inexpensive remote copy system can be realized.

    摘要: A storage system having a plurality of storage devices including a first type storage device and a second type storage device, a reliability attribute and/or a performance attribute of the first type storage device being different from a reliability attribute and/or a performance attribute of the second type storage device. The storage system also has a control unit and managing a plurality of virtual volumes. If necessary, a storage area allocated to a first portion of a virtual volume of the plurality of virtual volumes is changed from a first type storage area of the plurality of first type storage areas to a second type storage area of the plurality of second type storage areas while another first type storage area of the plurality of first type storage areas is allocated to a second portion of the virtual volume.

    摘要: There is provided a storage control system in which various controls to a plurality of storage controllers connected to each other can be effectively performed. The storage control system controls first and second storage controllers, in which a second storage controller 10 is connected to a first storage controller 1-1 to which a host system 1-2 is connected. With reference to a memory in which a table defining correspondence relationships between internal logical volumes and a host logical volume 32 of the second storage controller 10 is stored, a channel adapter 1-3 of the first storage controller 1-1 controls power supplies of driving mechanisms of storage devices corresponding to the internal logical volumes.

    摘要: Information about remote copy target volumes of other storage systems 2 each having one and the same original volume V1 is registered for each remote copy target volume in advance. When there occurs a failure in a copy source storage system 2, a copy source volume for remote copy target volumes using the storage system 2 having a failure as their copy source is selected newly from the registered copy source volumes, and remote copy is resumed.

    摘要: The present invention provides a storage control device which enables the time between failures to prolong as much as possible, though it uses HDD's whose mean time between failures is relatively short. The storage control device controls spindle motors in a manner that a spindle motor is rotated regarding the HDD of data which can access from a host computer and a spindle motor is stopped regarding the HDD of data which are clearly judged that a host computer does not access the data. Whether the host computers can access the HDD or not is judged by the fact that whether the memory region (internal logical volume) provided by the HDD is in mapped to the host logical volume or not which is recognized by the host computer and is able to access thereby.
