A control device to be connected to a host and a disk device including at least one Redundant Arrays of Independent Disks (RAID) set, the control device includes circuitry that performs data communication with the host by a protocol capable of connecting one logical device in the RAID set to each port, virtually sets a plurality of ports which are defined by the protocol, sets a plurality of logical devices in the RAID set included in the disk device, and connects the plurality of logical devices to the plurality of ports, respectively, and the circuitry is to be connected to the host through an interface.

Control device for connecting a host to a storage device

A storage control device that includes processing circuitry that receives second access instructions of a plurality of series generated based on a first access instruction for instructing writing of data in a first storage or reading of data from the first storage, through a plurality of channels, the storage control device being connected to a controller configured to perform writing of data in the first storage or reading of data from the first storage according to an instruction for accessing the first storage, reassembles the first access instruction based on the second access instructions of the plurality of series received by the processing circuitry, and outputs the first access instruction reassembled by the processing circuitry to the controller.

Storage control device utilizing a reassembly of first access instructions based on second access instructions

A storage controlling system, coupled to a storage apparatus including storage disk devices, receives writing target data, generates a parity in units of parity generation of a given length for the data, and stores the data and parity into the devices. The system includes a cache memory and controller. The controller includes: a reception section receiving a writing instruction including the writing target data and information for specifying a target sector to write the data to; a decision section deciding whether processing target data is held in the cache memory, the processing target data including at least one unit of parity generation that includes sector data stored in the sector and fraction data other than the sector data; and a writing processing section updating, when the processing target data is in the cache memory, the data based on the instruction and outputting the post-update data as the writing target data to the apparatus.
