Patent number: 8949634Abstract: An OOB sequence monitoring unit detects that an OOB sequence carried out between a base device as a superior device and a connection I/F which operates even if an extension device is in a standby state has proceeded to a given stage. Based on the detection by the OOB sequence monitoring unit, a power supply control unit instructs a starting power supply unit to supply power. When the extension device starts, the OOB sequence is carried out between the extension device and the connection I/F of another extension device in the same manner. As a result, extension devices are started in decreasing order from the extension device closest to the superior device.Type: GrantFiled: December 30, 2008Date of Patent: February 3, 2015Assignee: Fujitsu LimitedInventors: Yuichi Sakagami, Nina Tsukamoto, Oumar Thielo, Nobuyuki Honjo

Patent number: 7949799Abstract: A storage apparatus and method are provided. The storage apparatus including includes a basic storage device having a control unit and an add-on storage device configured to be connected to the basic storage device. The add-on storage device including a first request receiving unit receiving a first operation stop request output from the basic storage device to the add-on storage device second request receiving unit receiving a second operation stop request different from the first operation stop request, communication monitoring unit monitoring communication from the basic storage device, and operation stop processing unit performing processing for stopping the operation of the add-on storage device. The operation stop processing unit determines the validity of the second operation stop request on the basis of a monitoring result obtained by the communication monitoring unit, and stops the operation of the add-on storage device.Type: GrantFiled: August 22, 2008Date of Patent: May 24, 2011Assignee: Fujitsu LimitedInventors: Oumar Thielo, Atsuhiro Otaka, Hidetoshi Satou, Yukihiro Yoshiya, Nobuyuki Honjo

Publication number: 20060274646Abstract: An apparatus for managing a network connection between different types of networks via a master port includes a failure detecting unit and a master-port switching unit. The failure detecting unit detects a failure in other apparatus based on a frame for determining the master port transmitted from the other apparatus. The master-port switching unit switches, when the failure detecting unit detects a failure in the other apparatus, the master port of the apparatus from a standby state to an operation state.Type: ApplicationFiled: September 29, 2005Publication date: December 7, 2006Applicant: Fujitsu LimitedInventors: Daiya Nakamura, Atsuhiro Otaka, Oumar Thielo
