NEC Successfully Demonstrates Dynamic Partitioning (Hot-Replace) of CPU and Memory Resources at iExpo2006

TOKYO—(BUSINESS WIRE)—December 6, 2006— NEC Corporation today announced it has demonstrated the world's first dynamic partitioning of CPU and memory resources on the Beta 2 version of Microsoft(R) Windows(R) Server, code-named "Longhorn," using NEC's enterprise server Express5800/1320Xf. Express5800/1320Xf is a large-scale, high-reliability server that can run up to 32 Intel(R) 64-bit Dual-Core Itanium(R) 2 processors. The demonstration was conducted during the iExpo2006 exhibition held on December 6-8 in Tokyo, Japan.

Dynamic partitioning allows the replacement of failed modules, as well as the replacement of hardware that show signs of impending failure, on mission critical systems while still in operation.

The NEC Express5800/1320Xf contains up to eight modules with CPU and memory resources. Each of these modules supports "hot-swap" and "hot plug" technology. By duplicating the system clock and cross-bar switch, the server also enables power and fan redundancy as well as replacement of each module without halting the system. Thus the CPU and memory modules have dynamic reconfiguration functions. This implementation confirms dynamic partitioning of the CPU and memory as a complete system using Windows Server "Longhorn."

"As a result of our close relationship with Microsoft, as well as the convergence between NEC's hardware/middleware technology and Microsoft's operating system technology, we were able to make this breakthrough possible," said Takayuki Noguchi, general manager, Computers Division at NEC Corporation.

"The dynamic partitioning capabilities of the NEC Express 5800/1320Xf enterprise servers will deliver a compelling solution for Windows Server "Longhorn" customers running scale-up databases, custom applications and line-of-business applications," said Bill Laing, general manager, Windows Server Division at Microsoft Corp.

Windows Server "Longhorn" is Microsoft's next-generation server operating system that is designed to provide more flexibility, greater control and increased protection. Windows Server "Longhorn," currently in Beta 2 and scheduled to be released in the second half of 2007, enables IT professionals to spend less time on everyday tasks and more time on high-value work that benefits their organizations.

Since NEC developed the world's first server (code name "AzusA") with 16 Intel Itanium processors in 1999, the company has continued to develop large-scale, high-reliability platforms utilizing the Itanium processor family. NEC will continue to develop and enhance mission critical enterprise servers such as the Express5800/1000 series, provide hardware- and software- based on the advanced platform technology VALUMO, and develop Itanium2-based business solutions.
