# Delta AI CDC Container Delta's AI CDC (Containerized Data Center) is a bolt-on high-density compute module designed for inference workloads at 30-40kW per rack. It sits alongside the standard MDC rather than replacing it. **Physical specs:** - Self-contained container with 3-4 racks - Rear door heat exchangers for cooling (water-side economiser loop) - Designed to bolt onto existing MDC deployments without modifying the base cooling architecture **Where it fits:** The standard Delta MDC handles up to 20kW/rack with DX cooling. When you need to run inference workloads that push 30-40kW per rack, you don't retrofit the MDC — you add an AI CDC container next to it. The cooling systems are independent. This is not for training workloads. Nvidia's GB300 at ~160kW/rack requires a fundamentally different approach (liquid cooling, different rack geometry). The AI CDC targets the middle tier — heavier than colo, lighter than full training. **Practical advantage:** You can deploy a standard MDC for general workloads and add AI CDC containers incrementally as inference demand grows. No rip-and-replace, no cooling redesign. --- Source: Delta Meeting 2 (Apr 3, 2025) See also: [[Density Tiering Principle]] | [[Rear Door Heat Exchangers]] | [[Modular Data Centers MoC]]
