More Efficiency and Sustainability Together

Efficient airflow is becoming increasingly important in modern datacenters. It directly influences system stability, cooling performance, and the overall sustainability of a datacenter.

Over the past year, we have approached several customers about “unfortunate” hardware installations — open rack units, incorrect airflow, or warm air being pushed into the cold aisle. Many responded quickly and made improvements, while some notices were ignored.
To keep our datacenter operations reliable, efficient, and technically up to date, we are now introducing a mandatory climate concept for all racks.

Why this matters

Correct airflow management provides immediate and measurable benefits:

• significantly more efficient cooling

• more stable and longer-lasting systems

• fewer hotspots

• a decreasing PUE

What’s changing

To ensure these benefits for all customers, the following standards will become mandatory:

• Blanking panels for all unused rack units

• Front-to-Back airflow only

• No warm air in the cold aisle

• Clear rules for GPU, storage, and other special hardware

• Transparent guidelines for power feeds and thermal loads

We are of course happy to support you with implementation — including consulting and technical assistance directly inside the datacenter.
If you require airflow adapters or deflection panels: just let us know.

The new climate concept is an important step toward using energy more intelligently and improving the long-term sustainability of our datacenter operations. This is not about creating limitations — it is about using resources responsibly and improving the stability of all customer systems.

We look forward to taking this next step together with you.
