Increased CPU performance in an affordable fault tolerant solution
Next in NEC’s family of Intel® XeonTM processor-based fault tolerant servers, the 
Express5800/320Lc delivers higher performance and added protection against 
downtime at the application level. Now enterprises running mission-critical 
Microsoft® Windows® applications can benefit from greater processing speeds 
without breaking the budget, and still achieve up to 99.999% continuous avail
ability. NEC’s Fault Tolerant servers deliver maximum uptime and ample storage 
capacity to meet the most demanding enterprise server requirements. 
ENHANCED PERFORMANCE FOR FASTER PROCESSING
NEC has expanded its line of fault-tolerant (FT) servers to 
include a high-performance, mid-range option for demanding, 
mission-critical environments. The Express5800/320Lc pro
vides faster processing speeds and higher availability with dual 
2.8GHz CPUs and NEC ExpressCluster Self Recovery Edition 
(SRE). Designed with Dual Modular Redundancy (DMR), the NEC 
Express5800/320Lc FT servers feature redundant CPU modules 
with Hyper-Threading enabled Intel Xeon processors. This 
configuration means data instructions are handled in parallel, 
instead of individually, to accommodate heavier workloads and 
produce faster response times for better overall performance.

server if applications fail to restart after a customer-set number 
of retries. SRE even monitors Windows OS resources and driv
ers and reboots the server should one of these components fail. 
With ExpressCluster SRE as a standard feature of the 320Lc, 
customers benefit from automated application restart and added 
OS protection—features that result in greater uptime and peace 
of mind that mission-critical applications will be available. Given 
that software failures account for almost 20 percent of all server 
failures, this added layer of protection at the application level 
significantly reduces downtime, creating a more reliable, highly 
available software environment.

NEXT-GENERATION FT TECHNOLOGY DELIVERS HIGH 
AVAILABILITY 
The Express5800/320Lc achieves up to 99.999% continuous 
uptime. Innovative lockstep technology employs duplicate 
fault-tolerant hardware components, so that the active spare 
components continue normal operation, even if a hardware 
component fails. All components are hot-swappable for rapid 
replacement, without interrupting operations. Because there 
is no single point of failure, downtime is nearly eliminated and 
data remains secure. 
IMPROVED UPTIME FOR APPLICATIONS
Now included with all NEC FT server models, ExpressCluster 
SRE monitors the performance of most application processes 
and restarts applications if failures occur. It can also reboot the 
 NEC Express5800/320Lc-R 4U rack-mount version

INNOVATIVE MANAGEMENT SOFTWARE ADDS VALUE
NEC’s FT servers include innovative software that increases 
the platform’s availability. Hardened drivers detect and prevent

writing beyond physical memory allocation. These drivers pro
vide diagnostic capabilities, as well as support for duplex and 
hot-swap operations. They are also certified for compliance and 
digitally signed for authenticity using Microsoft procedures and 
tools. NEC’s Express5800/320Lc includes NEC ESMPRO
Management Suite, which allows remote monitoring, analysis 
and management of all connected NEC servers in a lights-out 
environment. Also included is NEC EXPRESSBUILDER 
installation software for easy setup and system management. 
AMPLE STORAGE CAPACITY WITH NEC EXTERNAL  
SUPPORT
The Express5800/320Lc supports flexible storage options from 
leading storage providers, as well as NEC’s own RAID fibre 
channel disk arrays. The NEC S2800, for example, delivers high-
end class performance and functionality at an affordable price 
with 8 host ports (standard) and the ability to scale up to 27TB of 
storage capacity and 16GB cache (8GBytes per controller). With 
RAID6 double-parity technology, the S2800 achieves total 
redundancy, even when two disk drives fail, providing greater 
reliability and performance.
Key Features
• Dual Modular Redundancy (DMR) design 
featuring redundant, hot-swappable CPU and I/O 
modules for full hardware redundancy
• Automatic software restart for added protection 
at the application level
COMPACT DESIGN SAVES SPACE AND SIMPLIFIES  
MANAGEMENT
With an all-hardware, single-server server solution with automatic 
software restart and full fault tolerance, the Express5800/320Lc 
maintains affordability and a compact footprint. With a total 
chassis height of 7 inches and standard 
19-in rack width, the rack-mountable 4U platform easily 
accommodates space constraints without compromising 
performance. An all-in-one solution complete with management 
and installation software, the Express5800/320Lc reduces 
support and maintenance costs typically associated with 
multiple-server solutions and cluster configurations.
