SuperNBD: An Efficient Network Storage Software for Cluster

Networked storage has become an increasingly common and essential component for cluster. In this environment, the network storage software through which the client nodes can directly access remote network attached storage is an important and critical requisite. There are many implementations exist with this function, such as iSCSI. However, they are not tailored for the large-scale cluster environment and cannot well satisfy its high efficiency and scalability requirements. In this paper, we present a more efficient technology for network storage in cluster and also give detailed evaluation for it through our implementation – SuperNBD.The results indicate that SuperNBD is more efficient, more scalable, and better fit for cluster environment.
