    摘要: A controller for a storage device is connected to a host system and the storage device. A buffer memory includes first and second storage areas. A timer counts a preset given time in response to an instruction to start counting and sends a deadline notification when A given time is elapsed. A command responding portion, when receiving a read command from the host system, instructs the timer to start counting and thereafter outputs a read instruction to read data from the storage system. A data processing portion, in response to the read instruction by the command responding portion, reads specified data from the storage device and holds the read data in the second storage area of the buffer memory. A read control portion sends the host system the data held in the second storage area of the buffer memory when the deadline notification is received from the timer.

    摘要: According to one embodiment, a controller for a storage apparatus is disclosed having interfaces connectable to a host system, a first storage apparatus and a second storage apparatus. A data in the first storage apparatus and a data in the second storage apparatus are duplicates. A status table stores the operating state regarding the first storage apparatus and the second storage apparatus, wherein the operating state indicates among writing, reading, or standing by. A monitor monitors the interfaces and set up the operating state into the status table. A buffer memory buffers the data for writing in the first storage apparatus and the second storage apparatus. A command response unit receives the data for writing and write-in request from a host system, and directs the writing of the data to the first storage apparatus and the second storage apparatus while making the buffer memory buffer the received data.

    摘要: A controller is connectable to a host system and a plurality of storage devices. A monitor unit monitors operating status of a plurality of storage devices and sets the operating status of the storage devices in a status table. Upon receiving a write command from the host system, a command responding unit receives write data sent from the host system within a certain period of time after the write command, holds the write data received in a buffer memory, instructs a timer to start counting, sets a write destination for data in the status table, outputs a control signal that gives an instruction to write data to the storage device of the write destination, and returns a write completion response corresponding to the write command to the host system when receiving the deadline notification from the timer.
