STORAGE CONTROLLING DEVICE, AND ITS OPERATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a storage controlling device capable of efficiently using a full duplex type communication passage. SOLUTION: This storage controlling device connects to an upward processing device through the full duplex type communication passage and stores and manages data received through the communication passage into a data storing means. The storage controlling device has a plurality of channel processors for inputting or outputting data from a data storing means in response to a command included in the data (frame) transmitted from the upward processing device, and assigns the channel processors for inputting or outputting the data related to the data (frame) in response to the command included in the data (frame).
