Abstract
An information processing apparatus that functions as a SUB controller that, for a command group formed of pairs each formed by a command prepared by a host controller and a status, executes processing of each command and returns a status of an execution result of the command processing. In response to a request for processing the command group from the host controller, the SUB controller acquires the command group therefrom as an original command sequence. The original command sequence is divided into a plurality of segments each formed by one or more commands and having a total volume not larger than a threshold. Command groups each formed of pairs each formed by a command and a status are independently set in one or more storage devices connected to the information processing apparatus. Each storage device is notified of a command processing request on a segment-by-segment basis.
