The Express5800 offers Active Upgrade,™ a feature that eliminatesthe need to disrupt server operations to conduct essential softwaremaintenance on the Windows® Server platform. Active Upgradeenables non-stop server operation while performing softwaremaintenance that often removes other servers from operation forseveral hours.system integritySince the FT system involves continuous checking of all instructionsand I/O operations in lockstep, the system provides an unsurpassedlevel of system integrity. Transient hardware errors that would benormally passed to the operating system and application layer areisolated proactively and transparently to improve the operationalstability and system integrity. The result is that there is no loss ofmemory state or corruption of data in the event of a system error.operational simplicityWith the support of leading operating system and virtualizationproviders, the 320Fc FT implements redundancy at the hardwarelevel, reducing failures to notifications and indicator light status.This approach significantly reduces the complexity associatedwith other forms of high availability such as clustering systems,and has the added benefit of simplifying system management andrecovery operations, since administration and configuration isperformed as a single-system view.Simplified deployment and operation, remote monitoring, standardapplication support and software license savings, Active Upgradetechnology and continued operation in the event of hardwarefailure, all make the NEC Express5800/320Fc FT deliver the utmostin operational savings. NEC’s FT server provides uncompromisedoperational savings.nec’s fourth-generation express5800/320fcfault tolerant (ft) server is the first in theindustry to deliver lockstep support for thelatest intel® cpu technology–supporting lowvoltage operation of dual-core andQuad-core “top bin” performance of theXeon® 5300 series processor.with fully redundant modules running inlockstep, the 320fc ft series delivers theutmost in high availability through protectionof memory and processing state. this allowsorganizations of any size to realize the highestlevels of availability and system integrity, withthe added benefit of operational simplicity.continuous availability—up to 99.999% uptimeEquipped with fully redundant and hot-swappable componentsincluding redundant memory, processors and I/O subsystems—the Express5800/320Fc achieves up to 99.999% continuousavailability. The complete line of NEC Express5800 series ofservers delivers the highest performance available with IntelQuad-Core and Dual-Core Xeon processors. Unlike conventionalIntel-based server solutions that are not fully redundant, NEC’s FTredundant server architecture eliminates single points of failureand isolates hardware failures immediately. This process savessignificant troubleshooting time and helps to preserve memoryand processor status.availability Total accumulatedoutage per/yr. # of 9’s90% More than 1 month 199% Just under 4 days 299.9% Just under 9 hours 399.99% Just under 1 hour 499.999% A little over 5 minutes 5Express5800/320Fc Serverenhanced features:» Increased logical memory capacity to 24 GB for applicationsand virtualization» Front side bus (FSB) speed enhancement (1333 MHz)» PCI-X and PCI Express I/O expansion» Choice of SAS or SATA internal disk support, as wellas certified support for NEC and third-party externalstorage subsystems
