Abstract

PURPOSE: To improve the reliability of a highly reliable system with use of a multiplex system storage by performing the coincidence processing for the equivalent restoration with a cluster to which an interruption is reported.
CONSTITUTION: A system storage SSUO stores the data given from a cluster and then reads out this data via a control circuit. An equivalent damage error detection circuit EDaO detects an equivalent damage error when no write is carried out to the write request given from a cluster CLEO. This detecting result of the EDaO is applied to an equivalent damage error transmission circuit ETC. An equivalent damage error report circuit ERbO is connected to the ETC and receives the detecting result of the EDaO. The ERbO receives the output signal (error report) given from an ETC' via an ERb'2 and also receives the output signal given from C and outputs these signals to the CLEO. Mean while an ERb'1 outputs the output signal applied to the ETC and C' via an ERb'3 to a cluster CLE1. So is with the clusters 2 and 3.
