STORAGE CONTROL APPARATUS

摘要

PROBLEM TO BE SOLVED: To process an I/O to be preferentially processed without being affected by any other I/O processing while maintaining performance by dividing the I/O processing into the priority processing and the non-priority processing, and processing the non-priority I/O while suppressing the processing. SOLUTION: A storage control apparatus 301 is provided with a memory 505 common to I/O processing control parts 501-504, and manages information for dividing plural I/O processing into the priority processing and the non- priority processing, and for controlling them in the memory 505. Thus, it is possible to operate the non-priority I/O while suppressing its processing.
