IBM, of Armonk, N.Y., is looking to improve the overall energy efficiency of its System x servers by making its PowerExecutive featurefirst introduced in its BladeCenter blade servers in 2004available in all of its System x servers, starting with the new Dempsey-based System x2650, x3550 and x3500 servers introduced May 23. They will be available June 9, said Rob Sauerwalt, director of brand management for System x and BladeCenter. PowerExecutive, which is part of the IBM Director server management software, enables users to monitor power usage in a server or group of servers, and develop data to track those trends to better manage the overall power usage in the data center, Sauerwalt said.In the third quarter, IBM will unveil PowerExecutive 2.0, which will enable users to cap the amount of power used by a server or group of servers, giving them more control over power consumption and ensuring that these servers wont go beyond the power capabilities of the data center."Now that I know what I use, I want to control what Im using," Sauerwalt said. "I want to set limits on what I will draw without hurting performance in the data center." He said Intel has done a good job with Dempsey in managing the power envelope, and that PowerExecutive takes advantage of the power-efficiency features in the chip. "Power management is not a software-only solution," he said. "You need to marry the software and the hardware." HP, of Palo Alto, Calif., is rolling out new ProLiant and BladeSystem servers powered by Intels new dual-core chip. The systems offer a number of energy-efficiency features, including power metering that measures power consumption and heat generation and a power regulator that can throttle down CPU power depending on the workload. Other new features include array controllers and SAS drives, and an automated migration featurethe HP ProLiant Essentials Server Migration Packthat makes moving to Intels new processor platform a point-and-click process, said John Gromala, director of server product marketing for HP. Before, administrators had to go through a laundry list of steps before making the move to a new platform. "With one click, this migration pack can move all of these over at one time," Gromala said. HP also is introducing the Integrated Lights-Outor iLO2 management processor, which enables administrators to remotely gain control of ProLiant and BladeSystem servers via a Web browser. The ProLiant DL140, DL360, DL380, ML150, ML350, ML370 and BL20p systems will be available in late June. Dell is bringing Dempsey to its Precision 490 and 690 workstations, which officials said will bring performance gains of 45 percent to 155 percent over current models. A Dell spokesperson said systems powered by Woodcrest will be announced later this summer. The announcement comes less than a week after Dell announced it was going to start selling four-socket systems powered by Opteron by the end of the year. Senior Writer John G.
