P27 / PHYSICAL SYSTEMS
SOURCE THE WHOLE PHYSICAL STACK.
Power, cooling, water, racks, cabling, robotics, monitoring, and safety. Coordinated around the operating brief.
01 / AI INFRASTRUCTURE STACK
Where P27 operates.
P27 focuses on energy and physical infrastructure beneath and around compute.
LAYER 05 / OUTSIDE P27 SCOPE
Applications
Software applications use AI compute. P27 does not supply the application layer.
LAYER 04 / OUTSIDE P27 SCOPE
Models
AI models run on compute platforms. P27 does not supply models or model services.
LAYER 03 / PHYSICAL P27 SCOPE
Infrastructure
Systems that house, power, cool, connect, move, monitor, and protect compute.
LAYER 02 / OUTSIDE P27 SCOPE
Chips
Compute silicon and accelerators sit inside the equipment layer. P27 does not supply chips.
LAYER 01 / PHYSICAL P27 SCOPE
Energy
Grid interface, generation, storage, conversion, and distribution connect available energy to the rack.
