Context
A national public-sector organization required a high-availability data center that could be built faster than a stationary facility while meeting strict reliability and energy-efficiency standards. The site had limited construction options and a fixed power envelope. The customer needed a turnkey, factory-tested solution that could be transported, assembled, and fully commissioned outdoors under all-weather conditions.
At a glance
Customer
Government agency (anonymized, Ukraine)
Use case
Secure on-prem compute and storage with high availability, fast delivery, and low OPEX
Outcome
Two-module MDC with hybrid free-cooling system, redundant UPS, fire suppression, and early-smoke detection
Transport & siting
Modular footprint, outdoor installation, relocatable
Time‑to‑deploy
Factory build and site commissioning within months
IT capacity
Up to 16 racks / 120 kW IT load
Challenges
— Time-to-value
Deliver Tier III-equivalent resilience within months, not years
— Energy efficiency
Integrate direct free-cooling to reduce operating costs
— Environmental limits
Outdoor installation, minimal site works
— Operational continuity
Maintain redundancy across cooling, power, and safety systems
— Mobility
Design the complex to be disassembled and re-assembled if needed
Solution
A two-module 40-ft ISO-based MDC complex joined along its long side, creating unified IT and MEP zones. The system combines direct free-cooling with precision air-conditioning and intelligent humidity control.
Each module was factory-built and fully tested (FAT), then shipped and installed at the customer site for SAT and commissioning. The MDC operates as a stationary facility but remains relocatable for future moves.
