A slightly different approach to archive this is to use "Adaptive
Infrastructure", a combination of Blade servers and a NAS storage. It will
enable you to switch the servers as needed. Blades are booted from the NAS
and get their information through a bootimage and can be switched
dynamically since all the setup is stored centrally. I think there are
already productive customers using this infrastructure.

Search SMP for "adaptive computing" or "adaptive infrastructure".

Maybe this will help you without using proprietary technolgies (such as
Veritas) which are not and will maybe never supported officially because SAP
will not certify tainted kernels.
