METHOD FOR CONTROLLING DATA TRANSFER AND DEVICE FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To solve such problem that the data transfer processing time is increased due to the mutual relation of the queuing of a data transfer controller and a data storage device in a conventional data transfer control method. SOLUTION: A main control part 10 of a data transfer controller 80 transmits a message through a communicating part 60 to another data transfer controller 80, and counts the number of data transfer controllers according to the return of the message. The main control part 10 sets the depth of a data transfer request queue 20 by using the final number of the data transfer controllers and the number of data storage devices and the depth of a data transfer processing queue 120 of a data storage device 100.
