The NFS filesystem was designed as a work-group filesystem, making a central file store available to and shared between a number of client workstations. However, more recently NFS has grown in popularity in the server room, connecting large application servers with back-end file servers. In this environment, where high-speed access to data is critical, high capacity interconnects like gigabit Ethernet, Fibre Channel and Infiniband are to be expected. With RDMA technology we can fully utilize the data capacity of these interconnects, while providing relief for host CPU and memory buses from the demands of managing a "fire hose" of data.Here we describe the use of RDMA as an RPC transport layer. We show that the NFS protocol running over this new transport achieves higher throughput than a conventional TCP transport along with a reduction in CPU utilization. The benefits of an RDMA transport are enjoyed not only by the applications that use NFS mounts, but extend to any RPC service that requires high speed and efficient transfer of large volumes of data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
