NEC Enterprise Server NEC Express5800/1000 Series NEC Express5800/1000 Technology Guide Vol.
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 per formance and better reliability is growing exponentially in enterprise IT platforms.

Supercomputer-class Performance Features for performance improvement ual-Core Intel ® Itanium ® processor and high-speed D inter/intra Cell cache-to-cache data transfer At the heart of the Express5800/1000 series server is the 64-bit Dual-Core Intel ® Itanium ® processor, redesigned for Increased Memory Bandwidth even faster processing of larger data sets.
VLC Architecture High-speed / low latency Intra-Cell cache-to-cache data transfer The Express5800/1000 series server implements the VLC architecture, which Very Large Cache (VLC) Architecture allows for low latency cache-to-cache CPU CPU CPU CPU Cache Memory Cache Memory Cache Memory Cache Memory data transfer between multiple CPUs within a cell. In a split BUS architecture, for a cacheto-cache data transfer to take place, the Memory chipset FSB data must be passed through a chipset.
Mainframe-class RAS Features RAS Design Philosophy Realization of a mainframe-class continuous operation through the pursuit of reliability and availability in a single server construct Generally, in order to achieve reliability and availability on an Continuous operations throughout failures; minimize the open server, clustering would be implemented. However, spread of failures; and smooth recovery after failures were clustering comes with a price tag.
Memory Mirroring Continuous operation even in the event of a non-correctable memory error The Express5800/1000 series server supports high-level memory RAS features to ensure that the server can rapidly detect memory CPU errors, reduce multi-bit errors and continually operate even in CPU CPU CPU the event of memory chip or memory controller failures. Memory Memory I/F Memory Controller Memory I/F Memory Controller Data 2 Cell Controller examples of those features.
Mainframe-class RAS Features Highly Available Center Plane System restoration after the replacement of a failed crossbar card no longer requires a planned system downtime The Express5800/1000 series server has separated and Crossbar Controller Mudularization Only the node that is linked directly to the failed crossbar will be temporarily shutdown modularized the crossbar controller which ordinarily would reside on the system center plane.
Modularization, redundancy and domain segmentation of the system clock Minimizes downtime, and avoids multi-partition shutdown due to clock failure Through modularization and redundancy, system downtime, due to the oscillator, but also in the clock distribution mechanisms so that clock failures, have been minimized. The Express5800/1000 series system downtime can be minimized. server has taken it one step further.
Mainframe-class RAS Features Enhanced error detection of the high-speed interconnect Intricate error handling through multi-bit error detection and resending of errored data Since higher speed interconnects are implemented to increase Without Check Features system performance, there are higher probabilities that interference noise will cause errors occurring along these Logic Circuits chipset Data interconnects.
Flexibility and Operability Pursuit of flexibility and operability in a system — Flexible resource virtualization using floating I/O for improved operability Investment Protection Smooth migration to future processors The Express5800/1000 series servers now support the Dual-Core � Intel® Itanium® Processor Family Roadmap Intel ® Itanium ® processors with two complete 64-bit cores on 2002 2003 2004 each processor.
