NEC’s Fault Tolerant (FT) Technology

NEC has pioneered high availability systems for more than a decade with the GeminiEngine™ a chipset specially engineered for transparent failover and system integrity, supports lockstep processing. One module continues to process without interruption or loss of data should a potential fault in the other module occur. Hot-swappable modules automatically synchronize and resume normal operations once the issue is resolved ensuring availability of mission-critical applications and environments.

The high availability and continuous processing capabilities of NEC’s Express5800 Fault Tolerant (FT) servers make it a dependable platform for mission critical applications. Modular hardware redundancy provides up to 99.999% uptime for affordable high availability in business critical environments. he hardware components of NEC’s Express5800 fault tolerant servers are replicated and modularized for full hardware redundancy.

Perfect For Virtualization

The NEC FT servers can deliver continuous availability for VMware and 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.Technical Specifications
