Patent number: 7876557Abstract: A disk array device comprises: a hard disk drive module including a disk for recording information thereon and having one side that has a length substantially equal to the diameter of the disk; a battery nodule; an operation module; a fan module having at least one cooling fan; a controller module having a controller; a power supply module provided for supplying power to the modules; a circuit board to which the above-mentioned modules are connected via electrical connectors; and a substantially box-shaped chassis in which the modules and the circuit board are housed. A front surface and a rear surface of the chassis are opened in a rectangular shape. A length of one side of the opened front surface of the chassis is substantially the same length as the one side of the hard disk drive module.Type: GrantFiled: June 9, 2009Date of Patent: January 25, 2011Assignee: Hitachi, Ltd.Inventors: Katsuyoshi Suzuki, Masahiko Sato, Kenichi Tateyama, Naoto Matsunami, Koichi Kimura, Hidehiko Iwasaki, Kenichi Takamoto, Kenji Muraoka, Takamasa Ishikawa, Nobuhiro Yokoyama, Kiyotaka Takahashi, Yoshinori Nagaiwa

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
