When Dell unveiled its M-Series blade systems earlier this year, the company pointed a very green spotlight on the machines, touting their high energy efficiency. That power savings stems not only from the machines' 90-plus percent efficient power supplies but an innovative cooling-system design and management software.

That power savings stems not only from the machines’ 90-plus percent efficient power supplies but an innovative cooling-system design and management software. The company certainly had a convincing green tale to tell, prompting me to do a deep-dive write-up in January. But the proof is always in the pudding, and Test Center Analyst Brian Chee had a taste just recently. In a hands-on test he did, indeed, find that system to deliver impressive energy efficiency: “For the six days we ran the system, our biggest, baddest blade (dual Quad Core Intel Xeon E5430 2.66GHz) used a grand total of 21.7 kilowatts of power. That’s nice!”Notably, energy efficiency isn’t a sole selling point for a machine, but Chee found plenty more to like about the system. You can read his review right here. Technology Industry
