This is very similar to what we are doing, except we have an additional
crossover network cable and a inhouse written lock on the disk to
prevent split-brain.  We also use the standby machine for our MRTG
installation, so it can failover in the other direction.  The adaptec
serveraid card also has some nice locking features.
