The networking configuration and deployment is also a crucial component for HCI deployments. In the Dell Integrated System for Microsoft Azure Stack HCI system used in this solution, we configured two Dell S5248F-ON switches as ToR switches with L2 multipath support using Virtual Link Trunking (VLT) for high-availability across the switches. We used them with the NVIDIA Mellanox ConnectX-6 Dx Dual Port 100 GbE QSFP56 Adapters to provide Remote Direct Memory Access (RDMA) with RDMA over Converged Ethernet (RoCE) capabilities for our storage network. The overall network architecture is described in Figure 9.
