NEC Server Express320F User Manual

Express5800/320F  
Next-GeNeratioN Fault toleraNt Server  
Key Benefits  
» Continuous availability for 99.999% system uptime  
» Affordable fault tolerance using Intel Xeon based technology  
» Hardware redundancy of all components  
Enhanced Processing Performance  
The Express5800/320F FT server features Quad-Core Intel Xeon  
processors, achieving a 20% performance gain over existing fault  
tolerant servers.  
Virtualization Operating System Support  
Virtualization software support allows for multiple guest operating  
systems to run in a single physical server, simplifying server  
consolidation and migration. Application failure risk may increase  
in virtual environments if the server hardware fails, because all of  
the applications in the virtual environment will be affected. With  
Fault Tolerant servers and their redundant modular architecture,  
the risk of these applications going down is eliminated due to the  
server’s continuous computing capability.  
Servers for Mission Critical Applications  
NEC Fault Tolerant (FT) servers provide an innovative solution  
to address planned and unplanned downtime for mission-critical  
IT infrastructure worldwide. The Express5800/320F server  
delivers exceptional uptime through dual modular hardware  
redundancy featuring Quad-Core Intel® Xeon® processors. These  
servers provide high availability through hardware redundancy  
in all components: CPU, memory, I/O, hard disk drives, and  
cooling fans.  
Reduction in Maintenance Time  
The optional Active Upgradesplits the FT server into two  
independently running systems and allows one of the systems  
to run critical applications without interruption while Windows  
security patches and program updates are being installed on the  
other system.  
The heart of this dual modular architecture is the GeminiEngine™  
chipset, which is designed to enable “lockstep” processing.  
Lockstep enables the processing of the operating system  
and application software on both modules concurrently,  
eliminating potential downtime if a hardware component fails on  
either module.
