e-SAFE: An Extensible, Secure and Fault Tolerant Storage System

With the rapidly falling price of hardware, and increasingly available bandwidth, the storage technology is seeing a paradigm shift from centralized and managed mode to distributed and un-managed configurations. The key issues in designing such system include scalability, extensibility and robustness to name a few. This paper describes e-SAFE , a scalable distributed storage system that deploys a pastiche of theoretical and practical techniques, providing tolerance of malicious faults, reduced management overhead such as periodic repairs, and very high availability at an archival scale. e-SAFE is designed to provide a storage utility for environments such as large-scale data centers in enterprise networks where the servers experience high loads and thus show temporary unavailability (as opposed to P2P systems, where servers disappear over the long run). Consequently, the design goals of e-SAFE is to provide high load resilience in a seamlessly extensible way. e-SAFE is based on the s...
