The RDMA_CONNECTION_INFO view returns one row for each Remote Direct Memory Access (RDMA) connection.
RDMA_LINK_INFO view
The RDMA_LINK_INFO view returns one row for each Remote Direct Memory Access (RDMA) link. The information represents all RDMAs, not just a single Network Redundancy Group (NRG).
