Distributed object storage architectures have become the de facto standard for high-
performance storage in big data, cloud, and HPC computing. Object storage deployments …

This paper explores the feasibility of a cost-efficient storage architecture that offers the
reliability and access performance characteristics of a high-end system. This architecture …

Data replication has been widely used as a mean of increasing the data availability of large-
scale storage systems where failures are normal. Aiming to provide cost-effective …

Large-scale cluster storage systems typically consist of a heterogeneous mix of storage
devices with significantly varying failure rates. Despite such differences among devices …

Massive storage systems typically replicate and partition data over many potentially-faulty
components to provide both reliability and scalability. Yet many commerciallydeployed …

This paper explores the feasibility of a storage architecture that offers the reliability and
access performance characteristics of a high-end system, yet is cost-efficient. We propose …

In this paper, we investigate a dynamic replica placement strategy to achieve minimum
repair time during a complete loss of data center in large-scale distributed object storage …

Highly available cloud storage is often implemented with complex, multi-tiered distributed
systems built on top of clusters of commodity servers and disk drives. Sophisticated …

Brick and object-based storage architectures have emerged as a means of improving the
scalability of storage clusters. However, existing systems continue to treat storage nodes as …

Network bandwidth between sites is typically more scarce than bandwidth within a site in
geo-replicated cloud storage systems, and can potentially be a bottleneck for recovery …
