Reliability & Affordability

The high availability and continuous processing capabilities of NEC's Express5800 Fault Tolerant (FT) servers make it a dependable platform for mission critical applications.

Modular hardware redundancy provides up to 99.999% uptime for affordable high availability in business critical environments.

NEC's FT Server Assurances


Fully redundant components - CPU, memory, motherboards, I/O, hard disk drives and cooling fans - and modular architecture run in lockstep as one logical server.


Transparent features eliminate the need to modify middleware or applications to achieve fault tolerant functionality.

High performance & scalability

Dual-socket fault tolerant server with the latest Intel® Xeon® processors deliver optimal performance.


Centralized remote management of hardware and power supply is performed on a single-server view.


Two servers integrated into one logical server means one operating system or software license, reduced power consumption and less management time.

What Makes NEC's FT Servers The Right Choice?

Explore how the simplicity, features and cost effectiveness of NEC's
'hyper converged' FT servers delivers 2 servers in 1 while requiring only a single license.

Protective Measures

The hardware components of NEC's Express5800 fault tolerant servers are replicated and modularized for full hardware redundancy.

GeminiEngine™ a chipset specially engineered for transparent failover and system integrity, supports lockstep processing. One module continues to process without interruption or loss of data should a potential fault in the other module occur. Hot-swappable modules automatically synchronize and resume normal operations once the issue is resolved ensuring availability of mission-critical applications and environments.

Simply Affordable 99.999% Availability

Take a closer look on how NEC Express 5800/R320 FT servers with CPU lockstep technology for failover and server virtualization protection can reduce downtime to less than 6 minutes a year with 50% lower TCO than a high availability cluster with VMware fault-tolerance software.
