Fuzzy Reliability of Mirrored Storage System Based on iSCSI

摘要

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 three implementations of mirrored storage system based on iSCSI, then the membership function of the states is defined and the reliability of mirrored disk system is analyzed by using the reliability theory based on fuzzy state.
