Unprecedented fault tolerance

Achieving near-zero downtime is for mission-critical businesses that cannot afford a single moment of failure. NEC Fault Tolerant (FT) servers provide an innovative solution to address planned and unplanned downtime for your most important applications. The FT servers deliver exceptional uptime through dual modular hardware redundancy and help maximize your business outcomes.

The NEC Express5800/ft series servers provide continuous availability through hardware redundancy in all components: CPU, memory, I/O, hard disk drives, and cooling fans.

High-availability Technology

The NEC FT servers provide an innovative solution to address planned and unplanned downtime for your most important applications. The FT servers deliver continuous availability for 99.999% system uptime (5 minutes of downtime per year) through its fully redundant modular hardware featuring Intel® Xeon® processors.

GeminiEngine™ The Heart of Lockstep Processing

The heart of the dual modular architecture is the GeminiEngine™ chipset specially engineered to synchronize redundant components and prevent CPU performance degradation due to hardware redundancy control. GeminiEngine enables "lockstep" processing, which allows the redundant components to process the same instructions simultaneously, eliminating potential failure points for continuous processing.

Active Upgrade™

Active Upgrade™ is a combination of system architecture and software that allows the administrator to perform routine software maintenance with minimal interruption.* The Active Upgrade technology addresses planned server downtime necessary to install upgrades and enhancements to operating systems, service packs, applications, and system software. The updating process has much less impact to business operations with Active Upgrade by splitting the fully redundant system into two independently running servers and enabling online upgrades. As an innovative approach to address a top concern of IT departments on dealing with the monthly patches issued by Microsoft, Active Upgrade ensures the availability of the Windows operating system.

* Active Upgrade™ is available on the Windows models only.

Rapid Disk Resync (RDR)

The RDR resumes disk mirroring by performing quick copies of only data changes, rather than entire disk data, helping reduce the resynchronization time and improving disk reliability and availability.

* The RDR is available on the Windows models only. 

Virtualization

Server consolidation with virtualization can significantly lower the TCO by reducing distributed servers and much of the maintenance related workloads and costs. By supporting VMware® vSphere and Microsoft® Windows Server® 2008 R2 Enterprise Hyper-V™ 2.0, NEC Express5800/ft series servers provide a virtualization platform of utmost reliability and availability.

In a virtualized environment, multiple virtual servers reside on a single physical server and its downtime can cause unprecedented damage. NEC FT servers reduce these costly risks by its fully redundant hardware and ensure continuous operation of your virtualized setting.

Fast Processing Performance

The Express5800/R320 server features latest Multi-Core Intel Xeon processors, achieving the same performance as conventional 5000 series Intel two-socket servers.

The FT Server can deliver a lower total cost of ownership compared to traditional high availability and traditional server solutions in the following areas:

• While physically two servers, the FT server presents only one logical server, requiring only a single operating system / hypervisor instance (Software Licensing Considerations)
• Since the FT Server is a single system, it can be installed seamlessly and without complex configuration and infrastructure
• Maintenance is also considerably less for the FT Server approach when compared to complex configurations and infrastructure
• The cost of application down time - which is amplified through virtualization

99,999% system Availability

Total element redundancy

Easy maintenance

Modular concept: each module can be identified, and easily extracted without calling upon particular expertise and requiring use of specific tools.

Standard components and software

The components (Processors, memory, hard disks, expander cards) used are the same ones as those found in a standard Intel server. Because of this, NEC is now able to offer fault tolerant solutions at reasonable price.

The Windows applications (Exchange, SQL server, SharePoint, etc...) used are identical to those installed on a standard server, therefore there is no need to modify them.

This also applies to the Windows 2003 R2 (1)

(1) Security patches and Service packs are subject to a preliminary validation before being applied.

Economic solution

Less expensive than a “cluster” based server. As there is only one copy of applications, there is no need for the server to be “cluster-aware”.
