Tier III/IV Design Standards
Redundant, sovereign-grade infrastructure built to Uptime Tier III and Tier IV standards for continuous AI operations.
Nexus Core Systems designs its facilities with multi-layered redundancy, fault tolerance, and zero single points of failure. All sites follow Tier III/IV-aligned standards — with N+1 and 2N electrical configurations, dual-path cooling, and integrated fire, access, and monitoring systems.
Our multi-layered redundancy includes N+1 and 2N configurations, dual power feeds, advanced cooling loops, and geographically redundant power substations. These design choices aren't theoretical: they're already being implemented across our data center network, which is strategically engineered to support continuous AI workloads with no single point of failure.
Tier III Standards
Concurrent Maintainability
All Nexus facilities are engineered for modular growth and serviceability, allowing components to be repaired or replaced without shutting down live environments.
Planned maintenance with no IT disruption
Our architecture supports continuous operations during scheduled interventions — ensuring no downtime for AI workloads or GPU clients during maintenance windows.
N+1 cooling and UPS
Every Nexus site is built with N+1 redundancy for both cooling and uninterruptible power systems, guaranteeing uptime even during equipment failure or load transitions.
Tier IV Standards
Fault Tolerance
Nexus facilities are designed to withstand unplanned faults without impacting live operations, ensuring infrastructure continuity even during critical system failure scenarios.
Simultaneous component and path redundancy
Tier IV configurations include fully independent, physically isolated distribution paths for power and cooling — allowing concurrent delivery from two active systems.
2N Power Architecture
All power systems supporting Tier IV zones follow a 2N design, providing dual, fully redundant electrical feeds to every rack for maximum uptime assurance.
Technical Deployment
These Tier III/IV design standards are embedded into the Nexus infrastructure blueprint and are currently being implemented across our sovereign AI campuses in Morocco and North Carolina. The architecture is engineered for uninterrupted inference, LLM training, and high-availability GPU cloud environments.
20MW AI Campus Layout Phase-based design including dual AI halls, staging and office zones — optimized for Tier III/IV alignment and sovereign AI deployment.
