DIS for Azure Stack HCI offers a wide array of different networking options to suit a range of deployment sizes. For deployments that include heavy utilization of the underlying HCI storage, like SQL Server based deployments, we recommend using NICs with Remote Direct Memory Access (RDMA) capabilities.
Switch Embedded Teaming (SET) is the recommended mechanism for teaming NICs when used with Azure Stack HCI. Ports need redundancy while being isolated from the rest of the different networks created are ideal candidates. For instance, a SET can be created using ports which can be used for the management layer.
Azure Stack HCI supports Remote Direct Memory Access (RDMA) by implementing either the Internet Wide Area RDMA Protocol (iWARP) or RDMA over Converged Ethernet (RoCE) protocols. SET supports teaming RDMA adapter ports. With Azure stack HCI, if you have a single adapter with RDMA capabilities, it is identified as such during the deployment and assigned as the backend network for your storage traffic to maximize performance and capabilities.
