NEC Fault Tolerant Servers

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 servers provide continuous availability through hardware redundancy in all components: Processors, memory, motherboards, I/O, hard disk drives, and cooling fans.

NEC’s fault tolerant servers are designed with innovative technology that enables continuous availability for a solution with up to 99.999% system uptime while providing data integrity and exceptional performance.

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)

Disk-based backup products aim to achieve both the high-speed processing capability of disk and the cost advantage of tape-based backup systems. They are suitable for backing up data that can be highly compressed or data that requires generation management, as well as for storing data for a long period of time. By replicating the compressed data to a remote location, effective measures against disasters can be accomplished while keeping network costs low.

NEC Storage HS grid architecture, which incorporates multiple nodes into a mesh, allows you to add nodes without the need for system downtime and freely scale up processing capability as well as storage capacity. Additionally, with the “automatic optimal configuration” feature, data migration, when adding and removing nodes, is automatically processed. These technologies enable system upgrades that require fewer man-hours compared to that required when implementing an entire new solution.
