An information processing system includes a storage unit that stores association information that is obtained by associating identifying information of a plurality of second communication networks that are interconnected via a first communication network with identifying information of a virtual device that exists in the second communication network; a first specifying unit that specifies according to the association information a second communication network in which a target virtual device exists, in a case in which the first specifying unit acquires a request for a setting change to the target virtual device; a second specifying unit that specifies a physical server on which the target virtual device runs from among physical servers that exist in the specified second communication network; and a setting unit that performs the setting change to the target virtual device that runs on the specified physical server.

Information processing system and information processing method

After a first copy request is received and copy operation from a copy source area to a copy destination area is activated, information indicating an update section is recorded when a data update of at least one of either the copy source area or the copy destination area is generated. When a second copy request is received, data in the copy source area corresponding to the update section is copied to the copy destination area, in accordance with the recorded information.

Copy controller and method thereof

A processing method for copying between storage device data regions and a memory system are provided to allow immediate access in a state of having completed copying in response to a copy instruction, even when actual data is being copied in a remote system, thus preventing a decrease in the performance of the access to the copy source during copying. Processes include copying data in a data region of a copy source to an intermediate media data region for each prescribed block unit in response to a copy instruction, as well as copying the data copied to the intermediate media data region to a copy destination data region. Processes also include interrupting copying and processing an access when there is an external access for a block of the copy source or the copy destination data region during the copy processing.
