Full mesh topology
Full mesh topology connects each node to all other cluster nodes, as shown in the following figure.
This topology is highly reliable and fast, but it does not scale well. It is reliable because it provides many paths through the fabric in case of cable or node failure. It is fast with low latency because you can get to any node in the fabric in just one hop. It does not scale well because each additional node increases the number of fabric links and switch ports exponentially. This topology is suitable for smaller fabrics only.
