Actually, I was aiming more for hardware/performance; this because price:hardware can be very customer dependant. I'm comparing, for example, systems with X cpus of Y gigahertz, with Z core and Q busses.. At a glance, it seems that the case is still strong for power, on similar hardware numbers. I'm trying to comb my bias out of the analysis, but I'm strongly in Richard's camp: On 10/07/2011 11:56 AM, Richard Sims wrote:

My various generations of AIX on power substrate under TSM have been rock-solid for nearly 15 years now, and I've got 8+ TSM instances on each system image. So going 'wide' on less expensive, less performant hardware seems a questionable win at best. On 10/08/2011 03:46 AM, Daniel Sparrman wrote:
A Toyota Prius easily beats a Porsche in a price / performance comparison. However, would you still buy the Prius?
I like the metaphor, but I think it erodes the case I want. What's the maintenance on a Porsche average in the first 5 years? :) - Allen S. Rout
