The most fully redundant model would be to _not_ interconnect the 2 switches so it's 2 IB subnets rather than a single subnet. This means you need at least 1 SM on each subnet (with different subnet prefix) but you might want more if you're worried about some SM failing and not having an SM on that subnet. -- Hal -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
