I've used heartbeat (http://www.linux-ha.org) a few times before,
rather successfully - it just works. However, I'm now looking at
deploying it fro a project in a large organisation which has a very
expensive network infrastructure and there is some concern about how
their switches will react when packets from IP address w.x.y.z suddenly
start arriving in on port B when they used arrive on port A (I presume
this is an ARP issue of some sort). This has never been an issue
whenever I've used heartbeat before, but it has been raised by the
networking people in this organisation.
I realise that without more details about the networking
infrastructure, which I don't currently have, it might be hard to say,
but I'll ask anyway. In general, can this cause a problem, and if so,
how can it be obviated?
