In the scenario where the primary storage target IP is within the same IP block as the "high bandwidth" interface you describe, I don't think that a route should be needed beyond the normal block level route that sends traffic out that interface. My assumption is that the host's default gateway is going out the other interface in this scenario. Do you agree that this is the case, and that the issue only pertains to scenarios where the traffic would need a specific route to send traffic to a gateway on that storage network? -chip
