I saw this question come across my desk last night and thought it might be a helpful tip to some you out there. Not only did I think it was useful, it's really cool that we can do it and even script delays to turn on different servers to balance the...(read more)

Games vendors play . . . with power efficiency claims

Gary Thome — Mon, 18 Aug 2008 21:13:00 GMT

These days, server power efficiency is top of mind for everyone. Five years ago, most customers had no idea how much power a server used. Now, everyone knows - its a lot. In some cases, customers are making power consumption the primary criteria for vendor selection. So why is it so dang hard to get a straight story on exactly what options are the most power efficient? We'll fill you in on the dirty little secrets you need to know. ...(read more)

Green servers and ham

newtonja — Thu, 26 Jun 2008 14:21:00 GMT

I didn't know what I would eat for breakfast today, so thanks to Larry Dignan for the V8 slap up against the head this morning. After watching his video blog, "green servers and ham" doesn't sound so good anymore.

We know a lot of businesses wrestle with mandates to be "green". But at the same time many more are struggling to find any way to lower energy costs and to eek out more capacity from their facilities.

We agree with Larry that energy efficiency should not be an exercise in marketing. It's a serious business concern with a real-world engineering answer. That’s why we build Thermal Logic technology into every HP blade server to save power and cooling. That means energy efficient design married with energy efficient control - across the board. No special models, no “plant a tree” promotions, just common sense energy design + control with savings that you see on your electric bill every month and in the long life of your data center.

You decide if you want to take it to the bank or plant a tree with it.
