NFS has traditionally used TCP or UDP as the underlying transport. However, the overhead of these stacks has limited both the performance and scalability of NFS. Recently, high-performance network such as InfiniBand have been deployed. These networks provide low latency of a few microseconds and high bandwidth for large messages up to 20 Gbps. Because of the unique characteristics of NFS protocols, previous designs of NFS with RDMA were unable to exploit the improved bandwidth of networks such as InfiniBand.
