Semiconductor integrated circuit for communication, storage apparatus, and method for managing failure in storage apparatus

A semiconductor integrated circuit for communication (212) includes: a plurality of first circuit parts (2121) that are responsible for communicating with a higher-level apparatus (4); a plurality of second circuit parts (2122), which analyze a command included in a series of communication processes, and which share the processing of a plurality of commands included in the series of processes with another second circuit part; a common connector (2123) for connecting the first circuit parts to the second circuit parts; and a failure management part (2124), which, when a failure has occurred in any circuit part, causes the stoppage of processing by a stop-target circuit part that must stop processing.
