The Express5800 offers Active Upgrade,™ a feature that eliminates
the need to disrupt server operations to conduct essential software
maintenance on the Windows
®
Server platform. Active Upgrade
enables non-stop server operation while performing software
maintenance that often removes other servers from operation for
several hours.
Since the FT system involves continuous checking of all instructions
and I/O operations in lockstep, the system provides an unsurpassed
level of system integrity. Transient hardware errors that would be
normally passed to the operating system and application layer are
isolated proactively and transparently to improve the operational
stability and system integrity. The result is that there is no loss of
memory state or corruption of data in the event of a system error.
With the support of leading operating system and virtualization
providers, the 320Fc FT implements redundancy at the hardware
level, reducing failures to notications and indicator light status.
This approach signicantly reduces the complexity associated
with other forms of high availability such as clustering systems,
and has the added benet of simplifying system management and
recovery operations, since administration and conguration is
performed as a single-system view.
Simplied deployment and operation, remote monitoring, standard
application support and software license savings, Active Upgrade
technology and continued operation in the event of hardware
failure, all make the NEC Express5800/320Fc FT deliver the utmost
in operational savings. NEC’s FT server provides uncompromised
operational savings.

Equipped with fully redundant and hot-swappable components
including redundant memory, processors and I/O subsystems—
the Express5800/320Fc achieves up to 99.999% continuous
availability. The complete line of NEC Express5800 series of
servers delivers the highest performance available with Intel
Quad-Core and Dual-Core Xeon processors. Unlike conventional
Intel-based server solutions that are not fully redundant, NEC’s FT
redundant server architecture eliminates single points of failure
and isolates hardware failures immediately. This process saves
signicant troubleshooting time and helps to preserve memory
and processor status.
