Data Center Infrastructure as One Ecosystem from Grey Space to White Space
Data centers have become a critical part of digital infrastructure. They power everything from cloud services and financial systems to AI and mission-critical societal functions. The demands for uptime, capacity, and energy efficiency are higher than ever—and the consequences of downtime are correspondingly greater.
However, the risk rarely lies in what is visible, but in the underlying foundation. This is where the data center’s grey space and white space play a crucial role. Grey space includes the technical areas for power supply, transformation, and cabling, the infrastructure that keeps the entire system running. White space, on the other hand, refers to the areas where servers and equipment are housed, the space that can be expanded with capacity needs.
For data centers to operate optimally, grey space and white space must function as a whole. Data centers do not fail gradually—they stop. Therefore, it is essential to consider the data center as an integrated ecosystem, where all parts of the infrastructure work together to ensure stable operations.
SF6-free solutions and future-proof switching technology
At Følsgaard, we work with the entire chain—from energy supply to the internal structure of the data center—as one cohesive solution. At the same time, there is an increasing focus on environmentally responsible technology choices, including the use of SF6-free systems that reduce environmental impact without compromising operational reliability.
Alternatives such as air-insulated MILE and SmartCell systems from TE Energy are not pressurized, meaning their functionality does not depend on gas tightness. This eliminates the risk of gas leaks and reduces the need for continuous leak testing, while maintaining a high level of operational reliability.
The core building blocks of the infrastructure
A modern data center consists of a number of closely interconnected components, including:
- CSS stations (Compact Secondary Substations): Receive power from the grid and deliver a complete, ready-to-use supply unit with transformer and switchgear
- Transformers: Adjust voltage levels so energy can be used safely and efficiently in the data center
- Switchgear: Distributes power and protects installations from faults and overload
- Medium- and high-voltage cables: Transport energy reliably between stations and distribution points
- PDUs (Power Distribution Units): Distribute power to the active equipment in the racks
- Racks and cabinets: House servers and network equipment with focus on structure, cooling, and scalability
- Fiber and data cables: Ensure fast and stable internal data transmission
- Cable Management, labeling, and measurement equipment: Support installation, operation, and documentation
Value is created when these components are correctly dimensioned and integrated.
When the whole is overlooked
Challenges rarely arise in individual components, but in their interaction:
- Infrastructure that cannot scale
- Lack of redundancy leading to downtime, data loss, and significant financial consequences
- Multiple suppliers without overall responsibility increase the risk of legal complications
One system – one approach
When the entire infrastructure is treated as a single ecosystem, higher uptime, simpler implementation, and better scalability are achieved. With a unified approach—where cables, components, and systems are designed to work together—the infrastructure becomes a strength rather than a bottleneck.
A data center is not a collection of products. It is a system where each component plays plays its part and where the whole determines whether it works.
At Følsgaard, delivery of critical components is combined with technical advisory and system understanding. This means customers receive not only the right products, but also a Technical Partner who can help design and ensure a coherent, scalable, and reliable infrastructure.
