Regarding the power tangent (Score 2, Interesting)

We've been using virtualization technology for some time, but not on production server systems. We are considering doing that now for a variety of reasons (not the least of which include facilitating software upgrades and disaster recovery by leveraging the hardware abstraction layer). Because we run a [un?]healthy mix of operating systems, we are currently looking at VMware, but perhaps OSDN is in a position for considering Xen? It might well help your power needs scale much better.

Isn't there some Computer Science adage about solving problems by adding another layer of abstraction?
