Well what I'm looking for is two machines, but they must act like ONE machine
on the network. Load balancing is not that important. If one machine goes down,
the other one must just continue, but there must be mirroring between these
two, that if one comes up, the other one must update the one that has gone down.
I know HP has software for Windows NT that does this. These machines look as
one Machine on the network, but you can add any amount of machines to this
cluster. So serv01, serv02, serv03, looks like "serv", but it is actually 3
machines.
