Patent number: 9652421Abstract: A computer system includes a switch having a plurality of ports, a plurality of devices coupled to the plurality of ports, and a management system coupled to at least one of the plurality of devices and the switch. The coupling between the plurality of devices and the switch is a communication interface in which the number of master devices capable of existing in the same space is defined. The management system collects device coupling data of each of the plurality of devices coupled to the switch. Each of the device coupling data includes an ID of a port to which the device is coupled and information representing an attribute indicating whether the device is a master or a slave. The management system determines a coupling configuration on the basis of the plurality of the collected device coupling data and a communication interface protocol and, configures, to the switch, coupling information that is information in accordance with the determined coupling configuration.Type: GrantFiled: April 25, 2014Date of Patent: May 16, 2017Assignee: HITACHI, LTD.Inventors: Satoshi Muraoka, Keisuke Hatasaki, Mutsumi Hosoya, Yasunori Kaneda, Toshihiro Ishiki

Patent number: 8035989Abstract: In the invention, a finger board is bent like a “letter V”, and a thickness adjustment plate is provided between the finger boards of modules to be able to move, thereby being able to adjust the height of a finger. Such a configuration enables to increase the contact pressure of the finger by increasing the height of the finger when the finger is inserted, and when the finger is detached, reduce the contact pressure by reducing the height of the finger. This accordingly provides a shield chassis of suppressing any possible noise with no loss of insertability/removability.Type: GrantFiled: June 10, 2008Date of Patent: October 11, 2011Assignee: Hitachi, Ltd.Inventors: Tsutomu Hara, Junichi Funatsu, Toshihiro Ishiki

Publication number: 20110016201Abstract: A server system has, in addition to extensibility of scale-out type of a braid server system, extensibility of scale-up type by making SMP coupling among nodes. Each node has a unit for SMP coupling to other nodes. A module management unit responds to system configuration information to switch between a mode in which the node operates singularly as a braid server and a mode in which the node operates as a constituent module of an SMP server. Links among individual nodes are laid through equidistant wiring lines on a back plane and additionally a loop wiring line having a length equal to that of the inter-node link on the back plane is also laid in each node, thereby setting up synchronization among the nodes. Synchronization of reference clocks for SMP coupled nodes is also established.Type: ApplicationFiled: September 30, 2010Publication date: January 20, 2011Applicants: HITACHI, LTD., HITACHI INFORMATION TECHNOLOGY CO., LTD.Inventors: Toshihiro Ishiki, Naoto Sakuma, Junichi Funatsu, Takeshi Yoshida, Tomonaga Itoi, Morihide Nakaya, Shisei Fujiwara

Links among individual nodes are laid through equidistant wiring lines on a back plane and besides a loop wiring line having length equal to that of the inter-node link on back plane is also laid in each node, thereby setting up synchronization among nodes. Each node has a reference clock distribution unit mounted on back plane and adapted to distribute reference clocks to individual nodes and by switching reference clocks by a clock distributor inside each node, synchronization of reference clocks for SMP coupled nodes can be established.Type: ApplicationFiled: September 16, 2005Publication date: June 15, 2006Inventors: Toshihiro Ishiki, Naoto Sakuma, Junichi Funatsu, Takeshi Yoshida, Tomonaga Itoi, Morihide Nakaya, Shisei Fujiwara
