Physical Security

• Ring the perimeter with anti-climb fence
• Stop vehicles with barriers and bollards
• Funnel entry through guarded man-traps
• Watch with CCTV, IR, and motion sensors

Power Infrastructure

• Pull dual feeds from separate substations
• Step voltage down through transformers
• Back up with N+1 or 2N generators
• Bridge outages with UPS battery banks

Cooling Systems

• Reject heat through outdoor cooling towers
• Chill coolant down to the facility loop
• Cool the data hall with CRAH units
• Add liquid cooling for extreme heat loads

Compute Clusters

• Drive training with GPU and TPU servers
• Link nodes via NVLink and InfiniBand
• Feed clusters from high-speed storage
• Concentrate value in the data hall

Network Fabric

• Connect clusters with spine-leaf architecture
• Route core traffic through network rooms
• Terminate optics on patch panels
• Bridge internal and external networks

Data and Storage

• Hold training fuel in parallel file systems
• Stage assets in object storage
• Move data over RDMA fabric
• Protect the storage racks as crown jewels

Facility Zones

• Perimeter: fencing, cameras, IR sensors
• Power yard: feeds and transformers
• Network rooms: switches and optical panels
• Data hall: clusters, storage, RDMA fabric

Dependencies

• Map single points across power and cooling
• Identify ingress and egress chokepoints
• Trace generator and UPS bridge paths
• Flag where one failure cascades widely
