Events such as the floods in the Valencian Community in October 2024 have brought to the forefront the need to have an external backup copy outside of our own facilities.
Growing concerns about information security and its value have led to projected investment of around €6 billion in private data centers in Spain over the next three years. Leading analysts anticipate that total capacity will grow by approximately 25% between 2025 and 2030.
The main operating cost of a data center is that of maintaining the temperature below critical levels. Therefore, when discussing the dimensions of a data center, we typically only need to specify the installed electrical power, which fully determines the facility's size.

Data center electricity consumption in Europe already accounts for more than 3% of total consumption, and optimizing consumption and ensuring the sustainability of these centers is a priority for European Union administrations. To this end, full transparency and public disclosure are required for all data center projects larger than 2,000 m².

Optimizing Data Center Management:
There are different data center designs, but the one that prevails in small to medium-sized centers is the so-called "cold aisle" design. This creates a closed, cold zone, and exhausted air is vented to a warm zone (the rest of the room) and then to the outside. It is possible to recover this heat to produce energy.

A cold aisle is a modular enclosure based on two rows of racks with a central aisle enclosed by automatic or manual doors on the sides and from the top. In our cubes, the top has an automated opening compatible with automatic fire suppression systems.

This closed “cube” design forces the cool air drawn in from the floor of the central aisle to be expelled outside, passing through the rack cabinets where the active equipment is located. Therefore, better heat dissipation is achieved (around 60%), resulting in energy savings of approximately 40%.
Scalability must be a priority in the design of the passive equipment that makes up the data center. The data center should not be oversized, due to the unnecessary cooling costs this would entail, but at the same time, it must be scalable enough to meet the user's future needs.
Our range of data center equipment is fully modular, thus guaranteeing scalability at all times.

Maximizing Capacity.
In any case, the inherent maintenance costs, primarily refrigeration, can be allocated by volume, while data centers typically bill by units or by footprint. In other words, we find costs in three dimensions linked to revenue (return on investment) in two dimensions.
This leads us to try, by all means, to maximize the capacity of the racks housed in the cold aisles. Ultimately, a rack is a finite structure, 19 inches wide and 42 or 47 U high. Now it's a matter of fitting the maximum number of devices, connections, etc., into a limited space. Above all, to maximize the profitability of the refrigerated space.
At KEYNET, we manufacture cold aisle racks with a static load capacity of up to 1,500 kg. Our catalog lists no fewer than 18 different sizes, allowing us to adapt the system to the available space in the most efficient way.

Equipping the racks.
High-capacity connection systems are experiencing a significant boom in parallel with data centers. Until a few years ago, we could accommodate a maximum of 48 optical fibers in a 1U tray. Today, a standard ODF tray contains at least 96 connections. That more than doubles the number of connections in 1U.
ODF systems allow for different configurations. They can be presented in full front panels or divided into cassettes. New systems make it perfectly possible to accommodate 144 or 288 connections in a single U.

The introduction of MPO and MTP connectors allows us to connect up to 12 or 24 different fibers to a single connector. This type of connectorization eliminates the need for splicing. It is always preferable to use factory-terminated, tested, and traceable patch cords.

Its small size helps to reduce the size of the trays. Eliminating fusion significantly improves losses and attenuation.

At KEYNET, we produce high-capacity fiber optic systems for all fiber types (single-mode, OM3, OM4, OM5) and all types of connectors (conventional, MTP, and MPO in all versions).
The final factor to consider is the routing of incoming and outgoing cables. Depending on the density and size of the corridor, as well as the room's structure, routing is designed using floor, ceiling, or trays supported by the racks themselves, separating power cables from data cables.
KEYNET manufactures PVC and ABS cable trays to house cables conveniently and securely. We also supply zinc-plated steel hardware to support the trays from the ceiling or mounted on the racks. A wide range of accessories (brackets, bends, covers, etc.) allows us to meet any requirement.
