Why build a micro-module data center? How does it differ from a conventional data center?

1. Introduction

As a critical internal domain, the security and performance of a data center’s server room must be rigorously safeguarded. Micro-modular data centers represent a forward-looking evolution in data center design. In a modular data center, a large-scale facility is divided into several independent zones—each functioning as a self-contained module—where construction scale, power capacity, resource allocation, and other parameters are all designed and implemented according to unified standards. As IT equipment demands continue to grow, additional independent modules can be added incrementally on an as-needed basis, enabling rapid deployment and easy replication of existing data center infrastructure.

In light of the trade-off between demand and the need for low investment with high returns, it is essential to meet the future requirements of cloud computing, virtualization, and blade servers. Server To meet the demands for high density, low power consumption, rapid deployment, and flexible scalability—thereby effectively enhancing data center operational efficiency, controlling capital expenditures, and supporting the fast deployment of data halls under 300 square meters—we have introduced modular data center facilities. A modular data center is a comprehensive data center solution that integrates cabinet systems, power distribution, cooling, monitoring, structured cabling, fire protection, and other subsystems into a single, cohesive platform, achieving seamless integration of power supply, cooling, and management components. This enables modular data centers to operate intelligently and efficiently, allowing customers to maximize returns with minimal investment and thereby reduce operating costs.

Modular data centers can be deployed in small to medium-sized data center rooms ranging from 50 m² to 100 m², supporting both concrete-floor and raised-floor installations. These modular solutions enable rapid and flexible deployment on demand, reducing construction timelines by up to 50% compared with traditional data center facilities. They are primarily suited for high-density, localized deployments within conventional data center spaces and for the fast-track construction of small to medium-sized data centers.

1. What are the differences between a micro-module data center and a traditional data center?

Compared with traditional construction approaches, the modular data center construction model offers numerous advantages: it not only meets customers’ business needs but also delivers greater value, making it the new standard and guiding direction for future data center development. Below, we will outline the key differences between modular and traditional data center construction for your reference.

Challenges facing traditional data centers:

1. Long construction period

Depending on the specific circumstances of each project, the construction cycle for a traditional data center is typically divided into four phases: the decision-making phase, the implementation preparation phase, the implementation phase, and the commissioning and completion phase, with the entire cycle lasting approximately 400 days.

2. Poor scalability

Scalability is critical for adaptability: system capacity should be planned based on an analysis of future business needs and worst-case scenarios. However, organizations often lack the ability to foresee conditions three to four years down the line, leading to over-provisioning.

3. High energy consumption

Massive Power Losses: The operation of data centers requires substantial amounts of electricity. Traditional construction practices, however, have not adequately addressed issues related to power consumption, cooling, and airflow management, resulting in high data center energy efficiency ratios (PUE). While conventional, seemingly highly reliable environmental and power systems are often deployed, these systems tend to be inefficient, driving PUE values above 2.0—often much higher. This means that roughly half of the energy consumed by a data center is used to power IT equipment, while the other half is consumed by critical physical infrastructure, including power distribution equipment, cooling systems, and lighting.

4. Computer Room Operations and Maintenance High difficulty

IT operations and maintenance is grappling with numerous challenges and is mired in poor service quality: operations are conducted in a loosely structured, ad-hoc manner, resulting in unclear asset inventories; frequent staff turnover further exacerbates the problem, as new team members often lack comprehensive knowledge of all IT resources, making effective management virtually impossible; the absence of a unified service contact point leads to disorganization in incident response and fault-resolution tracking; and optimizing system operations requires IT personnel to accumulate vast amounts of data and generate detailed reports to draw actionable insights—yet routine IT operations management struggles to efficiently collect and analyze such data.

1. Advantages of Micro-Modular Data Centers

1. Rapid deployment and shortened construction timeline

Modular data centers accelerate planning and design, enabling system architectures to be configured in a rational manner aligned with design objectives. Mass production of modular units ensures ready-to-ship availability, thereby speeding up delivery; standardized connectivity reduces on-site configuration and cabling efforts, further accelerating installation; and the overall construction timeline for modular data centers is significantly shortened—while traditional data center projects typically require 7–8 months from concept to deployment, modular construction can reduce this to just 2–3 months.

2. Convenient for expansion and phased construction

By adopting a micro-modular architecture, data centers can be expanded incrementally, allowing for phased construction—from a single micro-module to dozens of micro-modules—based on evolving business needs. This approach ensures optimal configuration of IT spaces of any size within large data centers. Furthermore, the micro-modular data center solution significantly reduces total cost of ownership over the facility’s lifecycle.

3. Standard modules, stable and reliable

Micro-module data centers employ modular, standardized, and highly integrated design, ensuring exceptional system stability. Moreover, these data centers can be configured to meet specific customer requirements, offering power redundancy options such as N, N+1, and 2N, thereby achieving the highest TIA-942 Tier 4 certification level.

4. Green and energy-efficient

Throughout its operational lifespan, electricity costs represent the largest component of a data center’s total cost of ownership (TCO). Compared with traditional server rooms, micro-module data centers achieve more than a 12% improvement in cooling efficiency. By integrating liquid-cooling systems and natural cooling strategies, micro-module data centers can reduce their PUE to below 1.5.

5. Intelligent Management, Efficient Operations

An intelligent management system can help customers reduce energy consumption and resource usage, enabling multi-level, granular energy consumption management in data centers and accurately identifying sources of excess energy loss through a variety of reports. Based on Big Data Conduct analysis and develop energy-saving optimization solutions to build a green data center. Optimal asset management involves managing the entire network’s assets throughout their lifecycle, achieving closed-loop asset information management to ensure timely data updates and efficient administration. At the same time, it helps users formulate asset maintenance plans, enables proactive alerts within these plans, and allows for dynamic adjustments based on current conditions to deliver optimized solutions, thereby establishing a comprehensive optimal asset management capability.

1. Differences Between Micro-Modular Data Center Construction and Traditional Construction

During the construction of data centers, modular data center construction differs from traditional construction models in the following key aspects:

1. Integrated distributed deployment: batch replication and on-demand scaling—three separate systems consolidated into one.

By consolidating the UPS and battery room, the air-conditioning room, and the IT server room into a single IT server room, we have achieved unified and clearly defined building requirements and standardized interfaces. Modular construction is now implemented on an as-needed basis, shifting from a one-time, full-scale build of a single server room to phased deployment of individual micro-modules. Twenty modules were ordered and delivered in just 13 weeks, demonstrating rapid IDC deployment capabilities that can flexibly adapt to rapidly evolving business needs.

2. Decoupling of modules from civil engineering: one-time planning, phased investment, and rapid deployment

Civil construction and IT infrastructure are decoupled: the building’s main structure and its foundation, along with utilities, are constructed in a single phase, while data center modules can be deployed flexibly on an as-needed basis. All components of the data center modules are standardized products with pre-configured interfaces, enabling rapid manufacturing and shipment as well as swift on-site assembly, thereby effectively improving ROI and reducing Capex by 10%.

3. Decoupling of internal module components from channel structural components: enabling flexible adaptation to future changes

Server lifecycles typically range from 3 to 5 years, while data center equipment can last 10 to 15 years. When future server configuration changes occur, micro-modules can flexibly adjust the internal power distribution and cooling ratios to accommodate these changes, significantly enhancing their long-term availability.

4. Sealed aisle + in-row chilled-water precision air conditioning reduces PUE to 1.5: The sealed-aisle design isolates cold and hot airflows, while in-row precision air conditioners provide localized cooling and heat removal, eliminating hotspots and significantly improving cooling efficiency. On-site testing has demonstrated a PUE as low as 1.5, with OPEX reductions of 35%–40%.

5. Intelligent Management Architecture: Single-Module Monitoring and Cluster Monitoring Enhance Operations and Maintenance Efficiency

Each micro-module is equipped with a touch screen (featuring an independent intelligent management system) that connects to the switch and handles monitoring and management for that specific module. In addition, a northbound SNMP interface is provided to support cluster management at the micro-module level, with a clear and intuitive user interface that significantly enhances operations and maintenance efficiency.

1. Summary

As clearly demonstrated by the foregoing analysis, the modular construction approach offers significant advantages over traditional methods, delivering greater value while fully meeting customers’ business needs and thereby emerging as the new standard and guiding direction for future data center development.
