Disk array system with fail-over and load-balance functions, has microprocessor to detect failure in several channels to terminate operation of failed channel and to divide data into equal units for transmission through remaining channels

摘要

A microprocessor (110) detects a failure in one of several channels (131-134,231-234), so that communication operation through failed channel is terminated and transmission data is divided into several equal units for transmission through the remaining non-defective channels.
