What Is Coolant Hose Routing?_
Coolant hose routing refers to how the supply and return hoses are laid out from the coolant distribution unit (CDU) to each server node's cold plates. Proper routing avoids kinks, sharp bends, and contact with hot components to maintain flow and prevent leaks. It also ensures serviceability by allowing hoses to be disconnected or replaced without disturbing adjacent hardware.
Technical Details
Hoses are typically routed along dedicated cable management arms or vertical raceways to keep them separate from power and data cables. The bend radius must stay within the manufacturer's minimum to avoid flow restriction or hose fatigue. Quick-disconnect fittings are used at the server interface, and hoses are often color-coded (e.g., red for supply, blue for return) to prevent cross-connection. In dense racks, hose routing is planned per chassis position to avoid interference with GPU NVLink cables.
How Leviathan Systems Works with Coolant Hose Routing
The customer and OEM appoint qualified parties for the applicable cooling-system work and its acceptance. Leviathan does not install, connect, test, commission or maintain liquid systems. Any separately agreed physical IT installation or cabling work retains its own authorized scope and handoff.
