AMD and APC Cool
Off"> Meanwhile, AMD, of Sunnyvale, Calif., later this month will ramp up the speed in its 64-bit Opteron processor, while staying within the 95-watt power envelope for the 90-nanometer chip, officials said. When the company introduces its dual-core Opteron in the middle of this year, those new chips will fit within the same envelope, offering greater performance at the same power consumption level. AMD announced in December that its PowerNow technologya combination of chip instructions and softwarewill be available in Opteron.PowerNow, similar to AMDs CoolnQuiet technology found in the companys desktop chips, can dynamically increase or reduce the amount of power to the chip depending on the demand. Officials said they expect OEMs to begin turning on the technology in their systems in the first half of the year.To read more about AMDs cooling efforts, click here. Hillcos Jefferson said he has moved server racks farther apart to allow for better airflow between them and has installed a monitoring system to keep tabs on power consumption and heat generation. "I dont think Id be as comfortable going home for the weekend without the monitoring system," Jefferson said. APC is addressing such issues as these with equipment for the data center. The company, based in South Kingston, R.I., offers racks with integrated cooling and power management and air-conditioning units that run closer to the systems than standard wall units. "The most controversial topic right now is heat," said Neil Rasmussen, vice president and chief technology officer at APC. "The average data center today is built for 1.5 kilowatts per rack. And with blade servers, you can populate a rack with 20 watts of power." The ultimate solution, according to Gordon Haff, an analyst with Illuminata Inc. in Nashua, N.H., could be a combination of software that controls the systems and hardware that responds to the software. "The higher-level management software will have to [decide] what gets shut off, what gets powered down," Haff said. "But the hardware really needs to be able to do something useful in response."
