For automated takeover systems, especially critical ones (tho you can argue that any system setup with automatic takeover is critical by definition), you should have multiple heartbeat paths. Ethernet, serial cable, on shared disk, fibre or whatnot. Having false takeovers due to missed heartbeat on one set of ethernet cards could also likely be missed on another set of cards, even with a crossover cable. Maybe you should investigate alternate paths? -- //Morten Torstensen //Email: morten at mortent.org //IM: morten.torstensen at gmail.com I can't listen to that much Wagner.
