Why not get two Sun boxes connected by ethernet and run Oracle Parallel Server? You can also use dual mirrors to prevent downtime and allow for cold image backups. This may only provide redundancy at the database level not the OS or user process level, however. If you need the later, you have to accept the fact that redundancy is expensive.

You might also call Compaq. They just bought Tandem Computers a couple months ago. Tandem is a market leader in faul tolerant systems, esp in financial arenas. You do have to accept one fact: fault tolerance is expensive.

Enjoy!
