    Abstract: The present invention provides a high-performance storage access environment to a user who moves around a wide area, while increasing the fault resistance of the system. A plurality of network storages (volumes) is assigned to the user. Then, at the occasion of logging in to a volume by the user, the volume that can be accessed with high performance from a position he made access is located. Addresses at a computer with which user makes access are associated with addresses of the volumes provided by a storage device in advance in an assigned volume management table so as to increase access performance. Then, a management server performs control so that the address of the volume associated with the user access position is returned as a response, at the time of logging in.

    Abstract: Provided is a computer system including a first storage subsystem and a second storage subsystem. The first storage subsystem has a first storage unit and a first control unit. The second storage subsystem has a second storage unit and a second control unit. The first control unit records journals, and identifies, when data stored in the first storage unit is to be migrated to the second storage unit, which ones of the recorded journals are related to the data that is to be migrated. The first control unit chooses the identified journals one at a time in reverse chronological order, and judges whether or not the chosen journal corresponds to a data update made at some point between a current time and a time that precedes the current time by a length of a journal retention term set for the second storage subsystem.

    Abstract: A first storage system includes a first storage area for storing data written by a computer. A second storage system includes a second storage area to which the data stored in the first storage area migrates. A third storage system includes a virtual storage area corresponding to the second storage area. An access request to the virtual storage area is converted into an access request to the second storage area to be issued. A management computer transmits, to the third storage system, an instruction to migrate the data of the second storage area to a third storage area of the third storage system based on a determination result between a value of the data migrated to the second storage area and a predetermined threshold value.

    Abstract: A storage system has a pool which is made up of a plurality of storage regions supplied by physical disks, and allocates the storage regions within this pool to volumes supplied to host computers, and cancels such allocations. When a volume addition event has occurred, a management computer forecasts, for each volume, the capacity which is to be required at a certain time point in the future, based on usage capacities acquired for each volume, calculates a non-required capacity from this capacity which has been forecast and the capacities of the storage region groups which are already allocated to the volume, decides, based on one or more non-required capacities which have been calculated, whether or not there is a storage region enough to satisfy the capacity requested for a volume which is the object of addition, and, if a positive decision result is obtained, allocates storage regions equivalent to the non-required capacity to the volume which is the object of addition.
