CDU Selection & Deployment Guide

Compare in-row, in-rack, sidecar, L2L vs L2A and 2-phase CDUs with verified vendor specs and manual links, the flow/ΔT sizing math, installation requirements, a documentation hub, and an FAQ.

CDU Mini-BMS

An interactive cockpit per CDU type: datahall installation layout, a full ISA P&ID schematic, and live simulated parameters with sparkline trends — inject a fault (leak, pump-fail, clog…) and watch the controls respond.

Deep Comparison — All Aspects

Source-tagged comparison across worldwide common field issues, control systems & BMS/DCIM integration, after-sales & warranty per vendor, and TCO & maintenance burden by type — plus a 10-vendor capability matrix.

What is a CDU? A Coolant Distribution Unit hydraulically decouples the facility water loop from the chip-side technology cooling loop and regulates flow, temperature and pressure to direct-to-chip cold plates. This toolkit is an independent, educational reference built from published vendor datasheets and standards (ASHRAE TC 9.9, OCP, DMTF Redfish) — every figure is source-tagged, and links are validated. Not procurement, safety, or engineering advice.
