Summary

NFS/RDMA is a binding of NFS v2, v3, v4 atop RDMA transport, such as Infiniband and iWARP, providing significant performance optimization and enabling NAS in high-end environments. Benefits of RDMA include reduced client overhead, data copy avoidance, userspace I/O, reduced latency, and increased throughput. The NFS/RDMA protocol stack consists of NFSv3, NFSv4, NFSv4.1, RPC-TCP, RPC-UDP, and RPC-RDMA. Active protocol specifications are being developed by the IETF NFSv4 Working Group, including RPC/RDMA and NFS Direct. RPC/RDMA provides a core RDMA transport binding for RPC, while NFS Direct provides NFS binding for RPC/RDMA. Key features include encoding, inline and direct transfer, credits, and exactly-once semantics. Implementations are being developed on Linux and OpenSolaris, with next steps including further development and testing of the protocol specifications.
