DHTbd: A Reliable Block-Based Storage System for High Performance Clusters

Large, reliable and efficient storage systems are becoming increasingly important in enterprise environments. The authors' research in storage system design is oriented towards the exploitation of commodity hardware for building a high performance, resilient and scalable storage system. They present the design and implementation of DHTbd, a general purpose decentralized storage system where storage nodes support a distributed hash table based interface and clients are implemented as in-kernel device drivers. DHTbd, unlike most storage systems proposed to date, is implemented at the block device level of the I/O stack, a simple yet efficient design. The experimental evaluation of the proposed system demonstrates its very good I/O performance, its ability to scale to large clusters, as well as its robustness, even when massive failures occur.
