A Network World testclaims that Linux – and notably Red Hat's Enterprise Linux (RHEL) 5.1 – turnsout to use considerably less power than Windows Server 2008.
"Our tests point to Linux as the winner of the green flag bymargins that topped out at 12 per cent. But we must note that our results are full ofstipulations imposed by our test bed, and as the more truthful caradvertisements might warn -- your wattage may vary," says Network World's report.
Linux wins out
"We ran multiple power consumption tests using WindowsServer 2008 Enterprise Edition, Red Hat's Enterprise Linux (RHEL) 5.1 and SUSEEnterprise Linux 10 SP1 on four, popular 1U server machines, one each from Delland IBM and two from HP," it continues.
"The results showed that while Windows Server 2008 drewslightly less power in a few test cases when it had its maximum power savingsettings turned on, it was RHEL that did the best job of keeping the power drawin check across the board."
It’s an interesting test and sure to stimulate much debate,with eco-friendly power-saving considerations becoming increasingly importantin the development and marketing of technology in general.
