Cheap Servers Get Data Center Creds: Page 2 of 3

Gross says the next version of this software stems from the nuclear industry and the space shuttle, and is called multivariant state estimation technique (MSET). "We use this as an operator decision aid. We want the human to make the decision, but the human can't watch 1,000 signals, 24 hours a day."

The trend toward smaller-is-better is also being backed up by Intel. Included in today's announcement about the Intel "Nocona" processor -- a Xeon model with 64-bit extensions -- there are new features for mediating electrical current across the chip, called demand-based switching. The vendor estimates that this could save up to 30 percent in power consumption.

IBM, which today announced servers based on the new Intel processor, has introduced new features for maintenance and cooling control. The servers have eight memory slots that hold up to 16 GBytes, and they'll come equipped with cooling features such as liquid barriers between chips, according to IBM. The machines also offer directional heat removal pipes, and counter-rotating fans to create turbulence inside the server and cool them. The models include two-way rack servers called the xSeries 336 and 346; towers called the 226 and 236; the HSC20 BladeCenter; and the single-processor model 206 tower and 306 rack servers, all shipping in the next 30 days, officials say.

IBM also announced other new technology last week, called eFuse. The software uses "microscopic electrical fuses" to reroute a chip's logic configuration based on system performance. So far, that technology has been the domain of IBM servers running the high-end Power 5 processors, but by next year it could even appear in products like cell phones -- so low/mid-range servers shouldn't be far behind, officials said.

Meanwhile, Dell and HP also unveiled new servers today, each touting improvements based on Nocona. Dell's servers use a standard called the Intelligent Platform Management Interface 1.5 to remotely administer and boot, for diagnostic purposes, when used with Dell's new OpenManage 4.0 software, officials say. In about a year, Dell promises support for the next version of the standard, IPMI 2.0, which adds security features.
