RDMA

Remote Direct Memory Access (RDMA) allows one computer to copy data directly to the memory of a remote computer across the network. This technology provides the foundation for other technologies to operate, and can provide substantial speed increases to data transfers. It requires hardware support, and at this time, most RDMA-capable networking equipment is in the higher-end range. Some of it requires that DCB be present and enabled. Be aware that placing RDMA-capable physical adapters into a team prevents utilization of RDMA.

RDMA is a foundational technology for SMB Direct, which is a new feature of SMB 3.0. It can greatly accelerate data transfers across SMB 3.0 shares, so where feasible, it is recommended for Hyper-V hosts that will store virtual machines on such shares. For R2 hosts, it will also greatly enhance Live Migration speeds when it is set to SMB mode (refer to the Live Migration section of Chapter 5, Network Design, for more information).

If your hardware supports it, RDMA...
