(InfoWorld) - IBM will license its technology for cooling servers with water instead of air to a Chicago-area company. Panduit, a global networking and electrical manufacturer, will license IBM's Rear Door Heat eXchanger product, a five-inch deep cooling door to be mounted on the back of a conventional server rack in a data center. Water courses through the door, cooling the processors in the server hardware. IBM's water-cooled system reduces server heat output in data centers by up to 55 percent, compared to air-cooled technology, said Tom Bradicich, chief technology officer for IBM's BladeCenter and System x server product lines. The heat exchanger isÂ part of IBM's CoolBlue portfolioÂ of products to manage data centers more cost-effectively, reducing the heat generated by the increased processing power of servers and the increased number of servers crowded into datacenters. Datacenter operators who use fans for cooling have been slow to embrace water cooling because "it's difficult to do water cooling inexpensively," Bradicich said Wednesday in an interview. But over the last 18 months, the growth of datacenters running more and more industry-standard x-86 type servers "has been getting extremely out of hand," he said. The growth drives up demand for electricity to run more powerful computers and to keep the equipment cool. High energy costs have made water-cooled solutions more viable. Water cooling is getting a closer look from some IT administrators, but they still have some reservations about it, said Michael Bell, a GartnerÂ analyst, in a Wednesday interview. Water cooling can be initially more expensive to introduce into a datacenter than air cooling, and IT managers worry about water systems leaking and causing damage, Bell said. Some are sticking their toe in the water-cooling pool cautiously, clustering their highest powered servers into one part of their data centers and introducing water-cooled technology only in that area. But as datacenter electricity bills grow, "I think we'll see water usage coming more into play," he said, adding that it now costs data centers as much to cool a server as to power it. IBM rival Hewlett-PackardÂ introduced a water-based cooling systemÂ for its high-density servers in January. Also in January, blade server maker Egenera introduced a product called CoolFrame that integrates Liebert's X-Treme Density cooling technology into a blade architecture. Liebert is a division of Ohio-based Emerson Electric.

How's about 32 DIMMs? Sun Microsystems today announced a pair of new four-core Xeon-based boxes that give customers just about the most performance and choice out of any low-end servers from a Tier 1 vendor. The fresh X4450, for example, packs four of Intel's 7300 series Xeon chips into a 2U system. All of the other major vendors require at least 4U for their four-socket units. The system also has a mouth-watering 32 DIMM slots with support for up to 128GB of memory. That should be enough to run your virtualization software.â¦

(InfoWorld) - Engineers at NEC and Hitachi are taking water cooling beyond the processor with a new PC designed to fit into the living room. The Valuestar W went on sale this week in Japan and packs a digital TV tuner along with a drive that can read and write Blu-ray Disc and read HD DVD. It's intended to take the place of a TV so it has to be quiet. Noise from the PC could ruin a good movie, so NEC turned to water cooling to keep the noise low. In most desktop PCs, a large heatsink is bolted to the top of the processor to dissipate heat, and a fan blows the heat outside of the case. A water cooling system pumps water through a heatsink on the chip to more efficiently get rid of heat. It's a more complex and costly arrangement, but a slower and quieter fan can be used. NEC has alreadyÂ used water cooling in several PCsÂ to reduce fan noise so the PC can't easily be heard. With the fan noise all but gone the company has now turned its attention to the next noisiest component: the hard-disk drive. "It's difficult to make a hard-disk drive quieter so we decided to dampen the noise," said Hiroshi Sakai, manager of NEC Personal Products' common engineering department. NEC wrapped the drive in noise-dampening foam, but that means the device gets much hotter, so the processor water cooling system has been extended. In the new PC water flows past both the processor and CPU to keep them. The system was developed with Hitachi, which has built up years of water cooling knowledge through its mainframe systems business. Hitachi showed its first water-cooled PC prototype in 2002 and has worked with vendors including Hewlett-PackardÂ on water-cooled systems. The Valuestar W is the fourth generation of water-cooled PC from NEC and the heatsink has been substantially redesigned since the first PC went on sale in 2003. Back then it was nothing more than a copper pipe snaked over the heatsink plate, but the latest model, developed with Hitachi, pushes water through channels that are less than a tenth of a millimeter wide. Hitachi licenses its water-cooling system to other vendors to help bring the price down. Hitachi itself has a small share of the PC market so it's unable to realize economies of scale through its own products, said Hideaki Gemma, general manager of Hitachi's IT thermal solution group. In addition to NEC the system has been licensed to some Taiwanese PC makers and some television makers, he said. The fourth generation system adds about Â¥10,000 ($86.43) to the cost of the Valuestar W, which is a lot in the competitive PC market place. But NEC hopes consumers will pay the extra money for reduced noise. A version based on an Intel Core 2 Duo processor with nVidia GeForce 8400 graphics, the Blu-ray Disc/HD DVD drive, 2GB of memory, a 750GB hard-disk drive, and 22-inch monitor costs about Â¥355,000.
