The networking configuration and deployment are crucial 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 system. Figure 5 shows the entire network architecture.
