The Decision: Traditional Build vs. Micro Module Data Center
You're responsible for delivering 50 kW of IT load at a remote site. The building has no raised floor, no dedicated cooling, and the power feed is barely adequate. A traditional центр обработки данных build would take 9-12 months and require structural modifications. A центр обработки данных на базе микромодулей can be on-site and operational in 8-12 weeks. That gap is the core of the decision.
A центр обработки данных на базе микромодулей is a factory-integrated enclosure that contains racks, power distribution, cooling, fire suppression, and monitoring. It arrives as a single skid or container, is connected to external power and network, and starts working. The trade-off is density and scalability versus speed and simplicity.
What a Micro Module Actually Contains
Think of it as a data center in a box. A typical 42U enclosure can house up to 10-15 kW per rack, with a total capacity of 30-100 kW. The cooling is usually direct-expansion (DX) or chilled water, sized to match the IT load. UPS modules provide N+1 redundancy, and a local controller manages temperature, humidity, and access.
The enclosure itself is insulated, weatherproof, and rated for outdoor use. You can place it on a concrete pad, near a factory floor, or on a rooftop. The internal layout is pre-designed, so cable management and airflow are optimized from day one.
When a Micro Module Data Center Makes Sense
Not every IT project needs a micro module. But there are clear scenarios where it's the best option.
- Edge computing: You need compute close to users or IoT devices, with low latency and minimal space.
- Temporary or pop-up capacity: A 3-month event, a construction site, or a disaster recovery drill.
- Remote or harsh environments: Oil rigs, mining sites, or military outposts where building a permanent structure is impractical.
- Rapid expansion: Your company acquires a new facility and needs IT running within weeks, not months.
- Colocation avoidance: You want to keep data on-premises for compliance or security, but lack a dedicated server room.
In these cases, the micro module's speed and self-containment outweigh the higher per-kW cost compared to a well-planned traditional data center.
Comparing Options: Traditional, Containerized, and Micro Module
To choose, you need to compare on cost, speed, and flexibility. The table below summarizes typical characteristics for a 50 kW deployment.
| Параметр | Traditional Build | Containerized Data Center | Центры обработки данных с микромодулями |
|---|---|---|---|
| Время развертывания | 9-12 months | 6-9 months | 8-12 weeks |
| Initial cost (per kW) | $8,000-$12,000 | $6,000-$9,000 | $7,000-$10,000 |
| Space required | Dedicated room, raised floor | Outdoor pad, 20-40 ft container | Single 19-42U enclosure |
| Масштабируемость | High, but requires construction | Moderate, add containers | Low to moderate, add modules |
| Cooling efficiency (PUE) | 1.2-1.5 | 1.3-1.6 | 1.3-1.5 |
| Mobility | Fixed | Relocatable with crane | Can be forklifted |
| Идеально подходит для | Large, permanent facilities | Modular expansion | Edge, temporary, or constrained sites |
Note that PUE values depend heavily on the local climate and cooling technology. In a temperate region, a micro module with free cooling can achieve a PUE of 1.3 or lower. In a hot desert, it might climb to 1.6.
Key Engineering Considerations
Before you order a micro module, you need to answer a few technical questions.
Power and Redundancy
What is your actual IT load? Not the nameplate rating, but the measured draw. A micro module's UPS is sized to support the load, plus a safety margin. For N+1 redundancy, you need at least two UPS modules. If your load is 30 kW, a 40 kVA UPS with N+1 gives you 30 kW of protected capacity. Verify the input voltage and frequency—most modules accept 208V or 480V, 50 or 60 Hz.
Cooling and Heat Rejection
The cooling system must handle the heat load, which is roughly equal to the IT power consumption. A 50 kW IT load generates о 170,000 BTU/hr. The module's холодопроизводительность is rated in kW or tons. In a hot climate, you might need a larger condenser or an economizer. Check the operating temperature range—most modules work from -20°C to 45°C ambient. Above that, you'll need a derating or an auxiliary cooling unit.
Physical Installation
The module's footprint is small, but you need clearance for airflow and maintenance. Place it on a level surface that can support the weight—a 42U enclosure with UPS and cooling can weigh 2-3 tons. For outdoor installation, add a lightning rod and ensure proper grounding. For indoor use, check fire codes and ventilation.
Step-by-Step Checklist for Deployment
Follow this sequence to avoid surprises.
- Define your IT load in kW and the required redundancy level (N, N+1, 2N).
- Choose a module size that can accommodate future growth—at least 20% headroom.
- Verify the site's power supply: voltage, phase, and available amperage.
- Plan the network connection: fiber or copper, and the required latency.
- Check environmental limits: temperature, humidity, and altitude.
- Arrange for a crane or forklift if the module is delivered on a skid.
- Schedule a factory acceptance test (FAT) before shipment.
- On delivery, inspect for damage and verify all connections.
- Commission the module with a load bank test to confirm performance.
- Train your staff on the monitoring interface and alarm procedures.
Common Objections and Answers
Часто задаваемые вопросы
Is a micro module data center more expensive than a traditional build?
On a per-kW basis, the initial cost is often higher. But you save on construction, labor, and downtime. For a 50 kW edge site, the total cost of ownership over 5 years can be lower because you avoid building modifications and can relocate the module if needed.
Can a micro module achieve a low PUE?
Yes, if you choose the right cooling option. In mild climates, free cooling or economizers can bring PUE down to 1.2-1.3. In hot climates, you'll need a more energy-intensive cooling system, but modern inverter-based compressors can still keep PUE below 1.5.
How reliable is a micro module compared to a traditional data center?
Reliability depends on the components and redundancy. A micro module with N+1 UPS and redundant cooling can achieve 99.99% availability, similar to a well-designed traditional facility. The factory integration often improves quality control.
What happens when I need to expand capacity?
You can add another micro module alongside the first. Some vendors offer modules that can be networked together. However, if you anticipate rapid scaling beyond 200 kW, a containerized or traditional build might be more cost-effective.
Can I install a micro module myself?
You can do the site prep, but the electrical and cooling connections should be done by certified technicians. Most vendors, including VERHI, offer installation and commissioning services to ensure warranty compliance.
