Abstract : It is highly important to design a reliable Distributed Storage System (DSS) in the age of increased growth of data. Secure and reliable storage of data have become the top priority for all organizations dealing with high volume of data. To provide availability, scalability and fault tolerance, Replication and/or Dispersal technique is adopted in DSS. The presence of hybrid failures in DSS highly affects its performance. To design a reliable DSS, hybrid failure should be modelled and handled. This paper explores how a Dual quorum (DQ) protocol can be integrated with Dispersal technique to provide security (confidentiality) in addition to the fundamental DSS features. The paper analyses the performance of DQ-dispersal with that of DQ-replication in the presence of hybrid failures. © International Science Press.
