IBM has introduced five new servers based on Intel's new 64-bit Xeon DP processor, the just announced chip codenamed Irwindale.

IBM's xSeries and BladeCenter systems include mainframe-inspired technologies such as calibrated vectored cooling. The servers use dual 64-bit Intel Xeon processors that boast a larger integrated 2MB L2 cache, providing up to an 18 percent performance boost based on informal Intel benchmarks.

"These new innovations from IBM and Intel offer clients more control over their processing power than ever before," commented Alex Yost, director of IBM eServer xSeries products. "As the need for smarter power use increases, customers need solutions that will help them manage their options and secure their systems against the threat of intrusion and instability."

New power efficiency and security functions
IBM said the chips' demand-based switching (DBS) better manages processing power in order to reduce cooling costs in data centres. For example, if a company's e-mail application required less power at night, DBS would automatically lower the power consumption of the application by up to 24 per cent, lowering overall power consumption and helping reduce cooling costs.

DBS fits with IBM's calibrated vectored cooling which, said IBM, is based on decades of IBM systems engineering. It optimises the path of cooled air flow through the system, allowing IBM to use fewer fans while maximising system density. The company said that, by layering DBS on top of its calibrated vectored cooling, it will provide the most efficient Intel-based servers on the market.

IBM will also use DBS in its forthcoming Power Executive solution to provide advanced power management at the solution and rack level for xSeries and BladeCenter servers.

In addition to DBS, IBM will support the new Intel XD - execute disable bit - feature across its entire xSeries line to provide customers with additional security that offers virus protection from buffer overflow.

The new 64-bit Intel Xeon processors will be available on the IBM eServer xSeries 226, 236, 336 and 346, as well as the IBM eServer BladeCenter HS20, by the end of February.
