GB200 compute tray cooling
Rack integration enquiryScope cooling integration for an OEM GB200 Grace Blackwell compute tray and its rack. The selected rack architecture determines the tray connections, manifold and facility requirements.
Fit and compatibility
- Identify the OEM rack and tray revisions and whether the design is NVL36×2 or NVL72. The NVIDIA reference configurations differ in compute tray and switch tray layouts.
- Check the specified manifold position, blind-mate or other connection arrangement, service clearance and OEM installation responsibilities.
Scope of supply
- Establish the boundary between the OEM cooling assembly, rack manifolds and the facility or CDU contractor. Specify the required interfaces, leak detection zones and telemetry handoff.
- Agree the scope for isolation, filtration, loop filling, service access and supporting site documentation before ordering rack-side hardware.
Operating conditions
- GB200 reference racks use hybrid cooling. Take the liquid and remaining air loads from the exact tray and switch configuration when sizing the secondary loop and room HVAC.
- Check the approved coolant chemistry, minimum flow, operating pressure, facility supply temperatures and agreed redundancy. Use the specified CDU duty and a rack hydraulic model.
Acceptance checks
- Record coolant condition and verified flow at the rack and critical branches. Check tray service access and verify leak monitoring end to end.
- Stage the workload ramp under OEM procedures. Confirm temperature and flow margins, alarm escalation and the response to a pump or facility-water failure within the contracted scope.
