Patent number: 7725664Abstract: A system creates a configuration definition table to be used for accessing a physical disk according to a host I/O request, to decrease a memory size of the configuration definition table even if common firmware is used for models with different scales. For this, a model correspondence table to show the definition of each model is provided in a configuration setup processing module, the maximum values of this model are recorded in a memory based on this content, and a memory area for each item is secured. And the actual content of the configuration definition is developed on the secured memory. Therefore even for a diversity of models, the memory size of the configuration definition table can be decreased to a size matching the model, with common firmware regardless the model.Type: GrantFiled: September 30, 2005Date of Patent: May 25, 2010Assignee: Fujitsu LimitedInventors: Hidejirou Daikokuya, Mikio Ito, Kazuhiko Ikeuchi, Shinya Mochizuki, Katsuhiko Nagashima, Akihito Kobayashi, Koji Uchida, Shinichi Nishizono

Patent number: 7567514Abstract: An interdevice communication monitoring unit 62-1 calculates a variable timeout time (T2?T) by subtracting an elapsed time T from a predetermined fixed timeout time T2 for monitoring an intermodule communication to monitor an elapsed time of an intermodule communication. The fixed timeout time T2 is a time shorter than a predetermined interface connection check time T1 for monitoring an interface connection with a channel. When the elapsed time T of the intermodule communication exceeds the variable timeout time (T2?T), the interdevice communication monitoring unit requests a channel to separate the interface connection, and then when an end response is obtained from a control module, requests the channel for an interface reconnection and then transmits an end response.Type: GrantFiled: September 20, 2005Date of Patent: July 28, 2009Assignee: Fujitsu LimitedInventors: Akihito Kobayashi, Hidenori Yamada, Katsuhiko Nagashima, Hideaki Omura, Koji Uchida, Shinichi Nishizono

Patent number: 7487289Abstract: In the present invention, for each set of blocks [#(0) to #(N?1)] storing update data, a history block [#(N)] storing an update state value, for example, a generation, time or check code, showing an update state is provided, constituting a set of management data as a check object. When writing update data on a disk, a new update state value is calculated for the same set of management data and stored in memory as update state confirmation value. The new update state value is also set as write data in the history block in the same set of management data, and the entire of the set of management data including update data and update state value are written onto a disk. The history block is read and disk write omissions are detected by comparing the update state value and the update state confirmation value stored in memory.Type: GrantFiled: February 7, 2006Date of Patent: February 3, 2009Assignee: Fujitsu LimitedInventors: Mikio Ito, Hideo Takahashi, Shinya Mochizuki, Hidejiro Daikokuya, Kazuhiko Ikeuchi, Hideki Yamanaka, Katsuhiko Nagashima, Akihito Kobayashi, Koji Uchida, Shinichi Nishizono

Publication number: 20080052537Abstract: In a redundant array of inexpensive disks (RAID) device, an encrypting unit encrypts data to be written back at a timing when a write-back processing unit performs a write-back of the data. The write-back processing unit stores the encrypted data in an encryption buffer, and then writes back the encrypted data stored in the encryption buffer to a disk.Type: ApplicationFiled: February 26, 2007Publication date: February 28, 2008Applicant: FUJITSU LIMITEDInventor: Shinichi Nishizono
