Enhanced Processing Performance
The Express5800/320F FT server features Quad-Core Intel Xeon 
processors, achieving a 20% performance gain over existing fault 
tolerant servers.
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
servers provide high availability through hardware redundancy 
in all components: CPU, memory, I/O, hard disk drives, and 
cooling fans. 
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.

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. 
Reduction in Maintenance Time
™
The optional Active Upgrade™ splits 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.
