NEC Express5800/320Lc
Fault Tolerant Server

• Up to 99.999% continuous uptime

• Rapid processing and improved application availability

• Streamlined installation and management

• High-performance solution for better ROI

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
