RDMA enables data in the storage server to be transferred directly to the RAM of the storage client. This communication bypasses many buffering layers required by TCP-based connections. RDMA has two main benefits for these workflows:
RDMA does have various requirements: a lossless network, flow control (global or priority flow control), and a supported NIC. The FilmLightOS onboard Mellanox driver has RDMA support. FilmLight does not recommend installing the Mellanox OFED drivers due to compatibility issues with SMB.
