For the most part, and especially with respect to data center class server systems, driving the performance component of the price : performance ratio has been our focus. But the economics of the industry are shifting...even evolving, as systems initial purchase price represents a decreasingly significant component of their "total cost of ownership" thanks to rising power and cooling costs. This trend coupled with the realization that overall data center utilization remains low (15% or so), implies the opportunities in this space are enormous.

Although performance remains key, at what cost should that performance be delivered? We *must* engineer systems to deliver the performance that Sun / Solaris customers have come to expect while using no more resources than is necessary to do so. Beyond performance, we must deliver efficiency. Therein lies the challenge of Project Tesla
