Patent number: 7046470Abstract: The information storage apparatus has an internal structure and arrangement of fans in consideration of the cooling effect. The capacity of the entire apparatus can be smaller than that of a conventional apparatus and an optimum air channel can be formed so as to maintain reliability of performance, life and the like of components at high temperatures. Further, relatively speaking, a module which does not produce a large amount of heat and does not require cooling is provided in a front stage of the channel while a module including heat-producing components and a cooling fan is provided in a rear stage of the channel.Type: GrantFiled: February 23, 2004Date of Patent: May 16, 2006Assignee: Hitachi, Ltd.Inventors: Akira Yamanashi, Hirokazu Takahashi, Takamasa Ishikawa, Kenichi Tateyama

Patent number: 7042722Abstract: An object is to effectively cool down an electronic equipment which is face with height limitations and tends to readily increase in heat generation amount to thereby provide the reliability required. The interior of a chassis of a control unit is partitioned by a back board into a front side space and a rear side space. In the rear side space, two control modules are attached so that these are stacked up and down, while two fan modules and a single duct member are attached in the front side space. Each fan module has two fans as built therein. A cooling air stream or “wind” from each fan flows into the lower-side control module through the duct member and others, whereas a cooling wind from the other fan flows into the upper-side control module. Even when either one of the fan modules goes down during operation, it is still possible by using the remaining fan module to cool down the both control modules.Type: GrantFiled: February 3, 2004Date of Patent: May 9, 2006Assignee: Hitachi, Ltd.Inventors: Katsuyoshi Suzuki, Hirokazu Takahashi, Masakatsu Horii, Kenichi Tateyama, Taro Takahashi, Hiroshi Suwa, Kouji Furuta

Patent number: 6970974Abstract: The present invention manages disk-drive types in a storage device in which a mixture of disk drives of a plurality of types with different interfaces is stored. The storage device enclosure stores a mixture of an FC disk drive 220F with a fiber channel interface and a SATA disk drive with a serial interface. The SATA disk drive is connected to a fiber channel via an FC/SATA interface connection device 233 that performs interface conversion. At startup and so forth, the controller 310 issues an inquiry to the enclosure management unit or to each of the disk drives and, based on the address allocated to each of the disk drives, or similar, automatically confirms the type of each disk drive and manages the confirmation results.Type: GrantFiled: March 25, 2004Date of Patent: November 29, 2005Assignee: Hitachi, Ltd.Inventors: Daisuke Isobe, Azuma Kano, Akihisa Hirasawa, Shingo Itagaki, Kenichi Tateyama, Yoshinori Nagaiwa, Nobuhiro Takahashi
