摘要： An information processing apparatus controls writing to a disk. A command reception section receives from a host apparatus a write command and a control command controlling a cache about the write command. A queue storage section stores a queue for the write command and the control command received by the command reception section. A control section determines which of a first write command for data of a file and a second write command for metadata corresponding to the file the write command stored in the queue is, groups, when the control command is received by the command reception section, at least one first write command and at least one second write command that have been received and stored in the queue, assigns an execution sequence numbers to the first write command and the second write command in the group such that data write of the first write command to the disk is executed in priority to the data write of the second write command, and controls execution of the first write command and the second write command according to the assigned execution sequence numbers.
