Procurement and Cooling Vendor Implications
Evidence
The primary vendor implication of the updated cooling architecture and doubled power density relates to CDUs and the rack-to-CDU ratio. Today, a CDU can support around 10 GB200 racks. With a rack generating about 2x the heat, that ratio would need to decline unless CDU capacity increases, implying either more CDUs or higher-capacity CDUs. We believe most major operators expect to maintain a ratio of around 10 racks per CDU. As rack power density rises, this points to larger CDUs. Today, in-row CDUs offer cooling capacities up to roughly 2 MW, but we expect future facility CDUs to reach 3-6 MW. Delta currently leads in the CDU specialist segment, alongside Schneider Electric, Vertiv, and nVent. Foxconn and Quanta dominate the system integrator category.
