Publication number: 20080228987Abstract: The present invention uses memory resources effectively and connects each storage device by a plurality of paths in a switchable manner, thus improving reliability and ease of use, by virtualizing external memory resources as internal memory resources. External storage 2 is connected to the main storage 1, and the actual volume 2A is mapped onto the virtual volume 1A. A plurality of paths is connected between the storage 1 and 2. When a failure occurs in a path in use (S3), the path having the next highest priority is selected (S4), and processing is continued using this path (S5).Type: ApplicationFiled: May 16, 2008Publication date: September 18, 2008Inventors: Shuichi Yagi, Dai Taninaka, Takao Mashima

Patent number: 7426517Abstract: The time (response time) from the issue of a display request for the display of constructional information to the obtaining of predetermined desirable constructional information and the completion of display is long when a terminal device having (a graphical user interface) to manage and control the operation of a storage system by using a storage managing server is used. To reduce response time, the storage managing server receives a first request issued from a storage managing terminal for executing the processing of the storage managing server, and a second request for executing processing including the communication of constructional information of a storage device between the storage device and the storage managing server. The storage managing server starts processing with respect to the second request before the storage managing server transmits a response to the first request to the storage managing terminal.Type: GrantFiled: March 3, 2004Date of Patent: September 16, 2008Assignee: Hitachi, Ltd.Inventors: Toshimichi Kishimoto, Shuichi Yagi
