There is not so much "to do" - of course you can write such a high-availability system yourself. We will talk again a few years from now, probably....

What you have to do is to install such a high-availability software and form a cluster. There are several such software out there: HACMP, Veritas, Beowulf, NonStop-Cluster and probably a few dozen others. As you mentioned you run on Itanium i assume you have HP-Ux as OS, so you will probably need to install NonStop Cluster from HP.

I suggest you read up about "Failover-Clusters" and "active-passive clusters", as this is what you describe.

I hope this helps.
