Ensuring Reliability in Deduplicated Data by Erasure Coded Replication Myat Pwint Phyu Thandar Thein As computer systems are taking more and more responsibilities in critical processes, the demand for storage is increasing due to widespread applications. Saving the digital information in a large disk is expensive and unreliable. As a result, if the disk fails all the data is lost. Therefore, the yearning for a better understanding of the system’s reliability is ever increasing. In greatest hit storage environments, deduplication is applied as an effective technique to optimize the storage space utilization. Usually, the data deduplication impacts the bad result for the reliability of the storage system because of the information sharing. In this paper, reliability guaranteed deduplication algorithm is proposed by considering reliability during the deduplication process. The deduplicated data are distributed to the storage pool by applying the consistent hash ring as a replicas placement strategy. The proposed mechanism is evaluated and the result is compared with pure replication and erasure coded replication. The proposed mechanism can provide the better storage utilization and the one hundred percent of assurance for demanded reliability level in compared with the existing systems. 2014-02-18 http://hdl.handle.net/20.500.12678/0000002926 https://meral.edu.mm/records/2926
