20080201593 | Storage control device - The storage control device of the present invention reduces the power consumption amount by stopping the transmission of power to enclosures that are not accessed. A plurality of additional enclosures are switch-connected via backend switches to a base enclosure. Drives that have not been accessed for a predetermined time or more undergo spin-down. When all of the drives in the enclosure enter a spin-down state, the supply of power from the power supply in the enclosure to the respective drives is stopped. The base enclosure that manages the system constitution of the storage control device turns OFF the switch connected to the enclosure when all of the drives in a certain enclosure have spun down. The transmission of power to this enclosure is accordingly stopped. | 08-21-2008 |
20090237877 | Storage subsystem - The storage subsystem is connected to an external device and comprises a storage device arrangement portion, on which a plurality of storage devices is arranged, and a control device that controls communications between the plurality of storage devices arranged on the storage device arrangement portion and the external device. The storage device arrangement portion is constituted such that the plurality of storage devices is arranged upright in the directions of two dimensions. | 09-24-2009 |

20100118484 | Storage Control Device - With the storage control device of the present invention, it is possible to mount a larger number of storage devices and to cool them effectively. A plurality of sub-storage units are provided within one storage unit. Each sub-storage unit includes a plurality of hard disk drives, a plurality of enclosures, and a plurality of power supply devices. A cover is divided into a front cover which covers over the front side of a case, and a rear cover which covers over the rear side of the case. Shield portions are provided on the upper sides of the hard disk drives and the enclosures. By these shield portions contacting the adjacent modules (other disk drives and other enclosures), it is possible to reduce the negative influence upon cooling air draft passages within the case, even when a cover has been removed. | 05-13-2010 |
20110004712 | STORAGE SYSTEM EFFECTIVELY USING FREE PORTS - A first free port present in a controller or a switch device is physically connected to a second free port present in a switch device (switch device in another storage device unit) other than the controller or switch device comprising the first free port. The possibility of logical connection via a physical path connecting the first free port and second free port is controlled. | 01-06-2011 |
20110264943 | STORAGE CONTROL DEVICE - The storage control device of the present invention reduces the power consumption amount by stopping the transmission of power to enclosures that are not accessed. A plurality of additional enclosures is switch-connected via backend switches to a base enclosure. Drives that have not been accessed for a predetermined time or more undergo spin-down. When all of the drives in the enclosure enter a spin-down state, the supply of power from the power supply in the enclosure to the respective drives is stopped. The base enclosure that manages the system constitution of the storage control device turns OFF the switch connected to the enclosure when all of the drives in a certain enclosure have spun down. The transmission of power to this enclosure is accordingly stopped. | 10-27-2011 |
20120226875 | STORAGE CONTROL APPARATUS - A storage unit is provided with a plurality of sub storage units configured to include a plurality of hard disk drives, an enclosure, a printed wiring board, a power supply device, and a cable holder. The sub storage units each operate separately. The enclosure is provided in the array of the hard disk drives so that the distance can be shorter between the enclosure and each of the hard disk drives. With the provision of the cable holder, communications cables can be both brought closer to the printed wiring board. With such a configuration, the coupling point among the communications cables and the printed wiring board, and the enclosure can be favorably reduced. The resulting storage control apparatus can be mounted with a larger number of storage devices, thereby being able to maintain good signal quality. | 09-06-2012 |
20120297114 | STORAGE CONTROL APPARATUS AND MANAGMENT METHOD FOR SEMICONDUCTOR-TYPE STORAGE DEVICE - The present invention is provided for maintaining and replacing storage devices systematically in accordance with schedule. A storage control apparatus | 11-22-2012 |
20120297159 | VIRTUALIZATION CONTROLLER AND DATA TRANSFER CONTROL METHOD - System for controlling data transfer between a host system and storage devices. A virtualization controller implements the data transfer and includes first ports for connection with the storage devices, a second port for connection with the host system, a processor, and a memory configured to store volume mapping information which correlates first identification information used by the host system to access a first storage area in one of the storage devices, with second identification information for identifying the first storage area, the correlation being used by the processor to access the first storage area. When data stored in the first storage area is transferred to a second storage area, the processor correlates the first identification information with a third identification information for identifying the second storage area and registers the first identification information and the third identification information in the volume mapping information. | 11-22-2012 |
