In today’s fast-paced business environment, all enterprises, from the world’s largest companies to the smallest depend on IT. Enterprise resource planning (ERP), customer relationship management (CRM), and business intelligence (BI ) all require that transactions are quickly processed and that the resulting data is reliable as to meet the requirements of the rapidly changing business environment. The need for higher performance and better reliability is growing exponentially in enterprise IT platforms.

People no longer consider mainframe systems and vector supercomputers as open enterprise IT platforms. However if one were able to have supercomputer performance and mainframe reliability for the cost of an open server in a datacenter, many may reconsider.

Next generation enterprise IT platform

NEC Enterprise Server Express5800/1000 series

Leveraging NEC’s vector supercomputer and mainframe technology, Express5800/1000 series is designed to meet the requirement of today’s mission critical enterprises.

With the new Dual-Core Intel® Itanium® processor 9000 series and the NEC designed third generation chipset “A3 ”, from chipset, board to system-level design, NEC has never compromised to realize mainframe-class reliability and supercomputer-class performance.

Express5800/1000 series is the perfect IT platform for the most demanding mission critical enterprises.

Supercomputer-class Performance

•High processing power by the Dual-Core Intel® Itanium® processor:

Dual-Core, massive L3 cache and EPIC (Explicitly Parallel Instruction Computing) architecture

•Very Large Cache (VLC) Architecture:

High-speed / low latency Intra-Cell cache-to-cache data transfer

•Dedicated Cache Coherency Interface (CCI):

High-speed / low latency Inter-Cell cache-to-cache data transfer

•Crossbar-less configuration (Available only on 1080Rf):

Improved data transfer latency through direct attached Cell configuration

Flexibility and Operability

•Resource virtualization through Floating IO:

Flexible resource management allows for robust server virtualization

•Multi-OS Support / Rich application lineup: Supports Windows® and Linux operating systems

•Superior standard chassis configuration: Small footprint and highly scalable IO
