  • Patent number: 8037362
    Abstract: One or more switches are interposed between a controller portion and a storage device. When transmission of a command to a certain storage device fails, a command is transmitted starting from an upstream side to a downstream side of a path between the controller portion and the switch to which the certain storage device is connected, and when command transmission fails while transmitting a command from a kth switch (k is an integer of 0 or more) which is connected to a (k+1)th switch and is one level upstream of the (k+1)th switch or from any port of the controller portion, it is determined that a failure has occurred in a power source that supplies power to the (k+1)th switch.

  • Patent number: 7992027
    Abstract: The power supply device of the present invention supplies power individually to a plurality of disk drives by rendering a plurality of DC/DC converters redundant. One redundant power supply substrate is assigned to a plurality of normal power supply substrates. One redundant power supply substrate supports the outputs of a plurality of normal power supply substrates. The main DC/DC converters in the normal power supply substrate correspond with the subgroups on a one-for-one basis. The secondary DC/DC converters in the redundant power supply substrate each correspond with all of the respective subgroups and are able to supply power to a predetermined single disk drive among the respective disk drives in the subgroups for each of the subgroups.

  • Patent number: 7925930
    Abstract: A storage control system of the present invention can carry out settings for a storage device using redundantly configured access channels. A controller of the storage control system can access a storage device using a plurality of access channels of system A and system B. Respective I/F control units each comprise a plurality of normally open-type switches. The switches of system A and the switches of system B are respectively wired-OR connected. A disk control unit outputs a control signal to an I/F control unit on the basis of a setting table. When a failure occurs in an I/F control unit of system A, the output signals of the respective switches transfer to a high-impedance state. Therefore, a storage device can be set by outputting, from an I/F control unit of system B, a signal corresponding to a desired operational mode and identification information.
