В чём разница между традиционным и модульным дата-центром?

Quick Answer: A модульный центр обработки данных is a scalable, factory-integrated, prefabricated solution that can be rapidly deployed by assembling standardised modules. In contrast, a traditional data centre is typically constructed on-site through a lengthy process involving separate infrastructure, power, cooling and IT installations. According to the Uptime Institute and the Telecommunications Infrastructure Standard (TIA-942), modular data centres significantly reduce deployment time, improve scalability and enhance energy efficiency compared to conventional facilities.

Research from the International Data Corporation (IDC) and the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) also suggests that модульное здание can reduce the risk of capital expenditure while enabling a quicker transition to cloud computing, edge computing, and AI workloads.

Введение

The rapid growth of artificial intelligence, cloud computing, hyperscale infrastructure, edge computing and digital transformation has led to a dramatic increase in the demand for data centre capacity worldwide.

When expanding IT infrastructure, organisations today face a critical decision:

Should they build a traditional data centre or adopt a modular data centre solution?

This decision affects:

• Capital investment
• Deployment speed
• Energy efficiency
• Масштабируемость
• Operational flexibility
• Long-term business strategy

For decades, traditional data centres dominated enterprise IT environments. However, modern digital infrastructure increasingly favours modular data centre designs due to their faster deployment cycles and predictable performance.

Data centre operators, cloud providers, telecoms companies, government agencies and enterprise IT managers need to understand the differences between these two approaches.

What Is a Traditional Data Center?

A traditional data centre is a permanent facility that is constructed at a specific location using conventional building methods.

The project usually includes the following stages:

• Site acquisition
• Civil engineering
• Building construction
• Electrical systems installation
• Mechanical systems installation
• Cooling infrastructure deployment
• IT equipment installation
• Testing and commissioning

The entire process can take months or even years, depending on the complexity of the project.

Traditional facilities are often designed as large, centralised infrastructures intended to support long-term operational requirements.

Characteristics of traditional data centres:

• Fixed building structures
• Large-scale mechanical rooms
• Dedicated electrical substations
• Centralised cooling plants
• Permanent expansion layouts
• Long design and construction cycles

These facilities are commonly used by:

• Fixed building structures
• Large-scale mechanical rooms
• Dedicated electrical substations
• Centralised cooling plants
• Permanent expansion layouts
• Long design and construction cycles

These facilities are commonly used by:

• Banks
• Government institutions
• Telecommunications operators
• Large enterprises
• Hyperscale cloud providers

What Is a Modular Data Center?

A modular data centre is a prefabricated facility in which critical infrastructure components are manufactured, integrated and tested in a factory before being delivered to the deployment site.

Rather than constructing every component on-site, modular solutions combine the following:

IT modules, power modules, cooling modules, battery systems, monitoring systems and fire protection systems into standardised units.

These units can be transported and rapidly assembled on location.

Many modern modular solutions offered by industry suppliers such as CIMC TLC, RYC and XLC utilise containerised or prefabricated designs that significantly reduce deployment timescales while maintaining enterprise-grade reliability.

Traditional Data Center vs Modular Data Center: Quick Comparison

Architecture Differences

Traditional architecture

Traditional facilities usually have a centralised design.

Infrastructure components are built separately.

• Building shell
• Cooling plant
• UPS rooms
• Generator rooms
• Data halls

Each subsystem is engineered and installed individually.

While this provides flexibility for customisation, it often increases project complexity.

Challenges include:

• Construction delays
• Coordination issues
• Cost overruns
• Longer commissioning periods

Modular architecture

Modular data centres use standardised building blocks.

Each module may contain:

• Server racks
• UPS systems
• Precision cooling
• Monitoring systems
• Системы пожаротушения

Because the modules are factory-integrated, most of the engineering and testing occurs before shipment.

This approach dramatically reduces on-site installation work.

The result is a more predictable deployment process.

Deployment Speed Comparison

One of the most important advantages of modular infrastructure is speed.

Traditional Data Center Timeline

Typical timeline:

Total: 12–36 Months

Modular Data Center Timeline

Typical timeline:

Total: 3–9 Months

This speed advantage is particularly valuable for:

• AI infrastructure deployment
• Edge computing expansion
• Telecom network rollouts
• Disaster recovery facilities

Scalability and Future Expansion

Modular infrastructure often outperforms traditional facilities in terms of scalability.

Traditional expansion challenges

Expanding a conventional facility may require:

• Additional construction permits;
• Structural modifications;
• Cooling redesign;
• Electrical upgrades.

These projects can be expensive and disruptive.

Modular expansion advantages

Modular facilities can be scaled up incrementally.

Organisations can deploy:

• One module today;
• Additional modules next year;
• Additional capacity as demand grows.
• This ‘pay-as-you-grow’ strategy improves capital efficiency.

Energy Efficiency Comparison

Energy efficiency has become a critical KPI for data centre operators.

Traditional facilities

Older traditional facilities often experience:

• Higher cooling losses
• Lower rack density optimisation
• Inefficient airflow management

Resulting PUE values frequently range between:

1.5–2.0.

Modular facilities

Modern modular data centres are designed with:

• Hot aisle containment
• Intelligent cooling
• Integrated airflow design
• High-efficiency UPS systems

Typical PUE ranges:

1.15–1.4

This translates into significant energy savings over the facility’s lifetime.

Cost Analysis

Capital expenditure (CAPEX)

Traditional facilities require a significant initial investment because they are often designed to accommodate future growth.

Modular systems, however, allow for phased deployment, reducing initial spending.

Operational expenditure (OPEX)

Modular facilities typically benefit from lower energy consumption, reduced maintenance requirements, faster troubleshooting and standardised spare parts, which can significantly reduce operating costs over time.

Reliability and Availability

In mission-critical infrastructure, reliability and availability are among the most important performance metrics when comparing traditional and modular data center architectures. Organizations operating in sectors such as finance, healthcare, telecommunications, and cloud computing require continuous uptime and minimal service disruption.

Availability Standards

Both traditional data centers and modular data centers can be designed to meet industry-recognized availability levels established by Uptime Institute.

Tier III Facilities

Characteristics:

Concurrently maintainable infrastructure

Strengths

• Fully customized infrastructure
• Proven long-term operational performance
• Extensive redundancy options

Challenges

• Complex on-site construction process
• Greater variability in installation quality
• Longer commissioning periods
• Increased risk of integration issues between multiple vendors

Reliability in modular data centres

Modular data centres are engineered using standardised, pre-integrated systems.

One of the most significant benefits of factory-built systems is that components are tested before deployment.

Components commonly tested include:

• Power distribution systems
• UPS infrastructure
• Системы охлаждения
• Monitoring and control platforms
• Network integration

Benefits of factory validation:

• Reduced installation errors
• Lower commissioning risk
• Faster deployment schedules
• More predictable operational performance

Because major subsystems are assembled and verified in a controlled manufacturing environment, potential defects can often be identified and corrected before shipment.

Reduced commissioning risk

A common challenge in traditional projects is that system integration largely occurs on-site.

Modular facilities reduce this risk through:

• Pre-engineered designs
• Factory acceptance testing (FAT)
• Standardised manufacturing procedures
• Repeatable deployment models

As a result, organisations often experience:

• Faster start-up times
• Fewer commissioning issues
• Improved early-life reliability
