Sun's 2008 summary of measured watts & watt/performance
Thursday Jan 08, 2009
Sun has shown measured watts with measured performance on UltraSPARC for over four years!:
2008: UltraSPARC T2+ T5240 & UltraSPARC T2+ T5440
2007: UltraSPARC T2
2005: UltraSPARC T1 & T2000 blogs with power-performance
Sun is now showing measured watts with measured performance for Xeon-based and Opteron-based servers as well, Sun is saying we are going see a lot more soon:
2008 Xeon: Virtualization, Web
2008 Opteron: Java, Mail, Web
Real measured watts on a variety of workloads with real-sized memory configurations is critical to truly inform customers. I heard that one vendor was giving out top-secret watt measurements in a 16C datacentre (61F) as a way to lower their watt numbers... but does that make any real sense? But let's look at the big picture: Datacentre managers need to be look at by "power usage effectiveness" (PUE). To keep a datacentre that cold you need to burn LOTS of watts -- so great way to slash your server numbers for marketing, but really net loss for a real customer.
Sun is looking at a variety of ways to save customers money. Take a look at this ZDnet article "Some like it hot: Why waste dough cooling down a data center?"
Expect to see many more measured results from Sun in 2009... its been years will any other system vendor step up and show the same or will they just do slick marketing and give you dozens of reasons why they can't give you a number you can simply measure? ...or ask you just to measure idle?

I guess you can keep a cold datacenter without bur...
Or you could put you datacenter in a hot clima...
Or you could bury them in any climate and take adv...
