Foundational

🖧 Hardware & Cluster Build-Out

SXM, PCIe and Rack-Scale Form FactorsGPU form factors determine how accelerators connect, receive power and get serviced. Compare PCIe cards, SXM modules and rack-scale systems against the workload and the facility.

Foundational

🖧 Hardware & Cluster Build-Out

Direct-to-Chip Liquid Cooling and CDUsDirect-to-chip cooling carries heat from cold plates to a coolant distribution unit. Flow, temperature, pressure and coolant quality all matter to the design.

Foundational

🖧 Hardware & Cluster Build-Out

Cables, Transceivers and the Optics Power BudgetCable selection depends on distance, port compatibility and power. Count both ends of optical links and check the exact part numbers before ordering.

🖧 Hardware & Cluster Build-Out

Accelerator Selection: H100 to B300 and RTX PRO 6000Choose an accelerator by checking memory capacity, memory bandwidth and compute throughput separately. Each limits a different part of the workload.

FEDITOR'S NOTE

Separate management reachability from host power state. Count affected work without double counting and coordinate electrical or cooling actions with authorized operators.
