According to one embodiment, an interface control apparatus includes an interface, a table, a command processor, and a controller. The interface transmits and receives information to and from a host. The table holds management information for managing an address in a memory space in the host. The command processor carries out a command process of accessing the memory space in the host using the management information. The controller releases the management information corresponding to the command process from the table in response to completion of the command process.

Interface control apparatus, data storage apparatus and interface control method

According to one embodiment, an interface control apparatus includes an interface, and a controller. The interface is configured to transmit information between a host and a data storage apparatus. The controller is configured to fetch request information making a processing request for the data storage apparatus, from an element being a storage unit of a queue provided on the host through the interface. The controller is configured to execute read request processing of fetching first request information divided into a plurality of elements and stored, with priority over second request information which is different from the first request information, when the request information is fetched.

Interface control apparatus, data storage apparatus and method for interface control

A data reading unit reads inner offset data from an offset reading in an inner direction toward a center of a storage medium and outer offset data from an offset reading in an outer direction toward a circumference of the storage medium. A data comparing unit compares the inner offset data and the outer offset data read by the data reading unit. A data-output control unit that outputs the read-data when a result of comparison by the data comparing unit indicates that the inner offset data matches the outer offset data.

Storage device, data-assurance control device, and data assurance method

A method of setting a parameter of a peripheral device, for controlling an operation of the peripheral device includes collecting and storing a command issued for the peripheral device by an external device, analyzing a command issue pattern for the peripheral device based on the stored command, and determining a most proper value of the parameter based on the command issue pattern. The most proper value of the parameter determined is set as a parameter for controlling the operation of the peripheral device.
