A storage system including: channel control portions each including a circuit board on which a file access processing portion for receiving file-by-file data input/output requests sent from information processors through a network and an I/O processor for outputting I/O requests corresponding to the data input/output requests to storage devices are formed; disk control portions for performing data input/output of the storage devices in response to the I/O requests sent from the I/O processors; and a computer communicatably connected to the channel control portions and the disk control portions. The storage system is formed so that when one of the channel control portions detects occurrence of failure in the channel control portion, the channel control portion gives a notice of occurrence of failure to the computer.
