You're the one that works at redhat, you tell me. :)
Seriously though, I'm sure Red Hat probably only supports the SAN
setup, the iscsi setup should be workable (there are companies using
it in production environments), the firewire, as I said, is only good
for testing. But from what I understand all the linux-cluster code
isn't really supported (as in approved for use on RHEL) by Red Hat at
this point anyways.
