Abstract: The configuration of a copy pair is prevented in which data replication is conducted from a secondary system to a primary system and data is protected. A first storage device manages first information including a first measurement result related to a command received from a first host, and a second storage device manages second information including a second measurement result related to a command received from a second host. When a management computer makes an instruction to configure data replication from a first volume to a second volume, a storage system determines whether data replication from the first volume to the second volume or data replication from the second volume to the first volume is replication from the primary system to the secondary system based on the managed first information and second information, and the determined result is displayed on the management computer.

Abstract: At least two virtual volumes of a plurality of virtual volumes are associated with at least one pool. At least two pools of the plurality of pools are associated with each of virtual volumes. At least two pools that are associated with each of virtual volumes have a priority level. A storage control apparatus receives a write command and the write target data from a host apparatus. When a virtual area of a write destination specified by the write command is an unallocated virtual area, the storage control apparatus selects one pool based on the priority level of the pools that are associated with a virtual volume of a write destination specified by the write command. The storage control apparatus allocates an unallocated physical area in the selected pool to a virtual area of a write destination, and writes the write target data to the allocated physical area.

Abstract: A storage apparatus automates a mapping operation and can automatically perform online data transfer from a storage unit of a data transfer source between a plurality of storage units. It includes a data transfer means for acquiring the construction information of the second storage in a first storage apparatus before a second storage unit is connected to a communication port for external connection, providing a storage device for performing data migrates from the second storage unit to a first storage control unit on the basis of the acquired construction information of the second storage unit, and performing mapping of the storage device in the second storage unit and data transfer from the second storage unit to the first storage control unit, with respect to an external connection function and an online data transfer function, after the second storage unit is connected to the external connection port.

Abstract: A data management method for managing performance data of a computer system which includes: a storage area for storing the performance data as data including performance information of the computer system and other data; and a controller for controlling the storage area, is provided. The data management method includes: a step in which the controller detects free space of the storage area; a step in which the controller determines a method for storing the performance data depending on the detected free space; a step in which the controller acquires the performance data; and a step in which the controller stores the acquired performance data in the storage area according to the storing method determined in the method determination step.
