GPU Rack Assembly & Integration_

Complete rack-to-production deployment for NVIDIA DGX, HGX, GB200 NVL72, and GB300 NVL72 platforms. From rail installation through POST verification.

The Problem_

GPU infrastructure is not traditional IT. A single GB300 NVL72 rack weighs over 1,360 kg, draws 120 kW, and requires mandatory liquid cooling. Incorrect assembly leads to thermal throttling, interconnect failures, and costly redeployment.

General data center contractors are trained for 5–15 kW server racks. GPU racks at 40–120+ kW demand specialized knowledge of high-density power distribution, NVLink domain topology, and precision cable routing.

Poor cable management in GPU racks directly impacts airflow and cooling performance. In liquid-cooled systems, improper hose routing can create kinks that restrict coolant flow, causing localized hotspots and GPU throttling.
