The following figure shows the two storage networks needed to create a dual-link direct interconnect between two clustered nodes (also known as back-to-back). The numbered blue lines indicate the recommended cabling order, beginning with the network adapter in the lowest slot number (port 1). After cabling storage, connect all nodes, LOM/rNDC/OCP, and ports 1 and 2 to a management/VM network.
Note: The two-node, back-to-back storage topology supports all available RDMA-based network adapters that are supported in the solution.
