Hi Hal, The only reason is cost down. The cost of IB switch weighs too much in our product, it seems the ring topology is the only way to go. There's no message across the ring, all the communication occurs within the ring. Would it cause the performance substantially go down?

Is it doable in OFED? I don't understand what you're trying to accomplish with this topology. In IB speak, each HCA <-> HCA link would be a separate subnet. Do you intend to forward across your ring ? If so, only some "router" mode would allow that with the topology you propose. -- Hal > Thanks! > Yicheng > _______________________________________________ > general mailing list > [email protected] > http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general > > To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general _____________________________________________________________________________ Scanned by IBM Email Security Management Services powered by MessageLabs.
