Fuzzy Reliability Analysis of an iSCSI-Based Fault Tolerant Storage System Organization

ISCSI is a newly emerging protocol with the goal of implementing the storage area network (SAN) technology over TCP/IP, which brings economy and convenience whereas it also raises performance and reliability issues. This paper presents a implementation of iSCSTbased fault tolerant storage system, and then analyzed the reliability of this system by combination of fuzzy logic and Markov modeling. This reliability method is a technique for analyzing fault tolerant designs under considerable uncertainty, such as is seen in compilations of component failure rates, the presented model provides the estimation of the lower and upper boundary of iSCSTbased fault tolerant storage system with a single run of the model.
