Highest Levels of Availability
NEC Fault Tolerant (FT) servers provide an innovative solution to address planned and unplanned downtime for your most important applications.
The Express5800/R320e servers deliver continuous availability for 99.999% system uptime (5 minutes of downtime per year) through its fully redundant modular hardware featuring 12-Core Intel® Xeon® processors that support lockstep operation.
Perfect For Virtualization
The NEC FT servers can deliver continuous availability for Hyper-V by using internal storage and standard management software.
Advantages of virtualization with the NEC FT server include proven scalable vCPU performance, integrated high availability storage for CapEX savings, and simplified virtualization deployment for CapEX and OpEx savings.
Simplified Manageability
The Dual Modular Redundant (DMR) design allows easy replacement of major subsystems without shutting down the system, by supporting hot plug of modules.
The Customer Replaceable Unit (CRU) is easily replaceable without any special skills.
Also, integrated EXPRESSSCOPE Engine 3 technology provides extensive remote management capabilities regardless of the status of the server’s power or operating system.
GeminiEngine™ — the Heart of Lockstep Processing
The heart of the dual-modular redundancy architecture for the FT server is its GeminiEngine™ chipset, a feature specially engineered to synchronize redundant components and prevent CPU performance degradation due to hardware redundancy control.
The GeminiEngine feature enables “lockstep” processing, allowing the redundant components to process the same instructions simultaneously, and thereby eliminating potential failure points for continuous processing.
Rapid Disk Resync (RDR)
The Rapid Disk Resync (RDR) is a disk synchronization technology that enables the disks to be resynchronized in a short period of time when their mirror has been broken due to a system failure or system maintenance.
The RDR resumes disk mirroring by performing quick copies of only data changes, rather than entire disk data, thereby minimizing the time that the system runs with non-redundant disk system.
* The RDR is available on the Windows models only.
