Maybe your looking for putting them in a virtual environment,
to cluster applications like that is fairly complex, Oracle has it's
own clustering(RAC), MySQL has clustering(with some potentially serious
limitations depending on your DB size), NFS clustering is yet another
animal, and samba clustering, well CIFS is a stateful protocol so
there really isn't a good way to do clustering there at least with
generic samba, that I'm aware of, if a server fails the clients
connected to it will lose their connection and potentially data if
they happened to be writing at the time.
In any case it sounds like clustering isn't want your looking for, I
would look towards putting the systems in VMs with HA shared storage
if you want to consolidate and provide high availability.
