That's not generally true. In almost all cases, you are better off using the bonded interface. > > My concern is that the new link would also have it's own IP.

Basically you would have to start with the second interface on a different subnet, establishing routing, etc. All nodes need to know about it. You're really better off with bonding. cliffw > > Thanks, > Jake > _______________________________________________ > Lustre-discuss mailing list > Lustre-discuss@lists.lustre.org > http://lists.lustre.org/mailman/listinfo/lustre-discuss _______________________________________________ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
