In a non-converged network topology, storage (SMB) traffic passes via dedicated NICs and is segregated from Management and Compute traffic. This topology is ideal for environments where you expect heavy write IOs. Management and Storage traffic will pass via a different pair of NIC ports. In the host operating system, a pair of RDMA capable NICs are used for storage traffic while Management/Compute can use any supported network card. The following figure shows this configuration in the host operating system.
