Remote Direct Memory Access (RDMA) is the remote memory management capability that allows server-to-server data movement directly between application memory without any CPU. involvement. RDMA over Converged Ethernet (RoCE) is a mechanism to provide this efficient data transfer with very low latencies on lossless Ethernet networks.

As of AIX 7 with 7100-02 the PCIe2 10 GbE RoCE Adapter can be configured to run in the AIX NIC configuration. As of AIX 7 with 7100-03, the OFED RDMA functionality was also added to the AIX NIC configuration. If you do not have the network-intensive applications that benefit from RDMA, then you can use the adapter as a Network Interface Card (NIC) only.

Mellanox OFED GPUDirect RDMA This new technology provides a direct P2P (Peer-to-Peer) data path between the GPU Memory directly to/from the Mellanox HCA devices. This provides a significant decrease in GPU-GPU communication latency and completely offloads the CPU, removing it from all GPU-GPU communications across the network.
