NEC Fault Tolerant (FT) servers provide an innovative solution
to address planned and unplanned downtime for your most
important applications. The Express5800/300 series servers deliver
continuous uptime through its fully redundant modular hardware
featuring Quad-Core Intel® Xeon® processors. These servers
provide continuous availability through hardware redundancy
in all components: CPU, memory, motherboards, 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 for
both its server modules. 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.
Key Features and Benefits
Fast Processing Performance
The Express5800/R320a server features Quad-Core Intel Xeon
processors, achieving the same performance as conventional
two-socket rack servers.
Lower Total Cost of Ownership
The FT Server can deliver a lower total cost of ownership over
the life of a server as compared to alternative high availability
solutions, such as software clusters. To run in redundant mode,
the FT server only requires one copy of the operating system and
application software license, no professional services to setup or
configure the server, and no cost or services are required to replace
a broken server module under NEC's warranty program. It's simple
to setup, simple to use, and simple to maintain.

Operational Simplicity
With the support of leading operating systems providers, FT
servers implement redundancy at the hardware level, reducing
failures to notifications and indicator light status. This approach
significantly reduces the complexity associated with other forms of
high availability such as clustering systems. It also simplifies system
management and recovery operations, since administration and
configurations are performed as a single system view.
