It's not. :) > does IB have node-level forwarding? No, you can't forward traffic between non-directly connected nodes in such a ring topology (without any switch). You would need intra-node routing mechanisms which are not present in OFED. I don't know in other implementations, though. Besides, for each cross-over pair, you'll be creating a separate subnet, and each subnet requires its own subnet manager. However, in a 3-nodes ring, each node can directly connect to all the other ones, and strictly speaking, you only have 2 subnets. So I guess node-level fowarding is not an issue, and that's probably a viable solution.
