B200 SXM cold plate
Configuration reviewEngineer a coolant loop around the approved HGX B200 SXM6 tray. Start with the chassis and cooling variant to match the assembly and rack interfaces.
Fit and compatibility
- Verify the exact B200 board and chassis. Lenovo documents the SR780a V3 with liquid-cooled HGX B200 and the SR680a V3 with air-cooled HGX B200.
- Check the approved SXM6 contact and retention drawings and tray manifold interfaces. A GB200 Grace Blackwell compute tray follows its own rack cooling design.
Scope of supply
- Define the OEM-supported cooling assembly and its mounting stack, tray manifold, isolation and mating connectors.
- Specify whether the work includes CPU cooling, rack-side connections, leak detection and CDU selection, with separate boundaries for the facility loop.
Operating conditions
- Lenovo documents a 1,000 W B200 SXM6 accelerator configuration. Eight GPUs at that device rating represent 8 kW before other server loads. Use the selected tray’s actual liquid and air heat split to size heat rejection.
- Use the assembly flow and pressure curves at the site coolant conditions. Verify the least-favored branch, rack pump duty and residual tray airflow.
Acceptance checks
- Check mating and service access on the selected tray and log branch flow and pressure at the approved operating point.
- Run the agreed eight-GPU workload and log thermal and throttle indicators. Exercise low-flow and leak alarms and confirm the planned response to cooling failure.
