Liquid-Cooled Compact Data Center Solution (CDCS)

Overview

With the rise of AI, the demand for high-density GPU compute is pushing traditional data center infrastructure to its limits. While cloud solutions offer flexibility, they come with high operational costs, security risks, and unpredictable expenses. AMAX addresses these challenges with the Compact Data Center Solution (CDCS), a fully integrated, on-premises solution that combines high-density computing, advanced liquid cooling, and intelligent cluster management into a unified, scalable infrastructure. The CDCS is ideal for small and medium-scale on-prem deployments, offering a balance of performance, efficiency, and cost control.

Benefits of On-Prem Computing with the CDCS

Organizations are reevaluating cloud spending as data generation increases and AI workloads scale. While the cloud offers flexibility, it comes with significant costs and security risks. Shifting to an on-prem data center with AMAX’s CDCS provides cost efficiency, security, and control. Customers making this shift have seen benefits such as lower operational costs, improved energy efficiency, and enhanced data security compared to cloud-based solutions.

Cost Efficiency & Predictable Expenses

Cloud costs are unpredictable due to variable pricing, network fees, and data transfers. AMAX CDCS provides a lower total long-term cost of ownership (TCO) with controlled operational expenses. By eliminating ongoing cloud rental fees and reducing power consumption through efficient liquid cooling, organizations achieve long-term savings and superior return on investment (ROI).

Enhanced Security & Compliance

Data privacy is critical for enterprises handling sensitive or regulated information. Cloud storage exposes data to breaches and compliance risks. With AMAX CDCS, data remains in-house, fully under your control, ensuring compliance with GDPR, HIPAA, and other industry regulations while reducing risks associated with third-party cloud storage.

Key Features of the AMAX CDCS

The CDCS features a closed-circuit cooling system, ensuring that the process fluid remains clean and contaminant-free while effectively dissipating heat through isolated circuits. This design minimizes maintenance needs and maximizes cooling efficiency.

Advanced Closed-Circuit Liquid Cooling

At the core of the solution is a closed-circuit cooling tower system. This setup utilizes a two-stage fluid circuit:

1. External Circuit: A cooling medium circulates over the coil, interacting with outside air to facilitate heat dissipation.
2. Internal Circuit: The process fluid circulates within the coil, transferring heat to the external medium, which is then dissipated into the atmosphere. This closed-loop system ensures that the internal circuit is isolated from contaminants, maintaining the integrity of the cooling process.

High-Performance Cooling for Servers

Our solution includes robust cooling systems designed to support high-performance servers:

• Leakage Detection: Integrated sensors monitor the system for leaks, ensuring operational safety.
• Noise Control: The system operates quietly, with noise levels kept under 70dB.
• Coolant Specifications: The cooling system operates with a specialized coolant mixture, maintaining temperatures up to 40°C with a specified flow rate, and achieving a coolant temperature delta of 10°C.

Manifold and Cold Plate Design

The CDCS employs custom-designed manifolds and cold plates to ensure efficient cooling distribution across servers:

• Manifold Design: The manifold is designed to achieve uniform cooling distribution, supporting both CPU and GPU cooling with precise flow rates.
• Cold Plate Design: The cold plates are tailored to the thermal needs of high-performance components, ensuring effective cooling across various server configurations. The design supports a maximum surface temperature of 62.8°C, with a cooling capacity sufficient to handle high thermal loads.

AMAX Patented Intelligent Liquid-Cooling Module

The intelligent liquid-cooling module is a key component of the Compact Data Center Solution, offering hybrid cooling modes that adapt to varying environmental conditions:

• Cooling Modes: The module supports multiple cooling modes, including energy-saving and high-performance modes, as well as a hybrid mode that combines both for optimal efficiency.
• Cooling Capacity: supporting power densities of up to 63 kW per rack while delivering remarkably low Power Usage Effectiveness  (PUE).

Smart Liquid Cooling Central Management

The CDCS includes a central management dashboard that provides real-time insights into the system’s performance:

• Key Metrics: The dashboard tracks real-time PUE, environmental health, power consumption, and cooling unit status, along with system alerts.
• Multi-Rack Support: The management system is scalable, supporting multiple racks for comprehensive data center monitoring.

CDCS vs. Traditional Air-Cooled Data Centers

Traditional air-cooled data centers have higher energy consumption, require more space, and incur greater operational costs. As AI workloads scale, these inefficiencies become more significant. Liquid cooling solutions like the CDCS improve cooling efficiency, reduce power costs, and enable higher compute density.

The table below highlights key differences between traditional air-cooled and liquid-cooled data centers.

Compared to traditional air-cooled data centers, the CDCS reduces annual operational costs by up to 46.7%. The shift to high-density liquid cooling optimizes energy use and maximizes available floor space while cutting power expenditures.

The Future of AI Infrastructure is On-Prem

The AMAX Compact Data Center Solution is designed for organizations looking to break free from cloud constraints and take control of their AI compute infrastructure. By integrating state-of-the-art liquid cooling with an intelligent management system, CDCS maximizes performance, reduces operational costs, and enhances security—all within a cost-effective, scalable, on-prem environment.
