NEC Express 320Lc - Manual (Page 2)

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.
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
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.
Increased CPU performance in an affordable fault tolerant solution
Next in NEC’s family of Intel ® Xeon TM 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.
