Overview of NFS Over RDMA

If InfiniBand hardware is available on the system, the default transport protocol changes from TCP to the RDMA protocol. The RDMA protocol is a technology for memory-to-memory transfer of data over high-speed networks. Specifically, RDMA provides remote data transfer directly to and from memory without CPU intervention. To provide this capability, RDMA combines the interconnect I/O technology of InfiniBand with the Oracle Solaris OS. However, if you use the proto=tcp mount option, NFS mounts are forced to use TCP only. For more information about using the RDMA protocol for NFS, see NFS Over RDMA.
