HARDWARE OF OUR DATA MANUFACTORY

Since December 2017, we have been operating our IT platform at the Telehouse data center in Frankfurt am Main (Kleyerstrasse 75, Gallusviertel).

We do not hand over any of our data. That's why we work exclusively on our own hardware and manage all systems ourselves. The sky above our cloud-free zone is blue...

Resources grow with requirements. Most recently, two new servers moved into our colocation facility in december 2025:

• energy distribution and two firewalls are located at the top
• six servers for workstations, applications, and backup share the center with a router
• three drawers at the bottom house materials and tools

The cable clutter on the back may look chaotic, but follows a well-thought-out plan.

Here is the inside of a server: you see the copper heat pipes, which transfer the heat from the processors - up to 360 watts - to the air flow. Are you thinking of a toy steam engine now, too?

IT and sustainability

are not necessarily contradictory: preserving value and avoiding waste go hand in hand for us. This works because we have invested in high-quality, durable, powerful, and expandable components from the outset, which remain technically sound and economically viable even after a long period of use. In order to reduce power consumption while maintaining the same functionality, we replaced a device for the first time in July 2025.

In addition, Moore's law has lost its magic on closer inspection: It is true that the density of integrated circuits in commercially available chips continues to double every 18-24 months. But because conventional manufacturing techniques have long since approached physical limits, density and computing speed are no longer in constant proportion. Today, performance enhancement in hardware is mainly achieved by parallelization rather than by increasing speed. To oversimplify, it's like adding a second or third engine under the hood to increase the top speed of a car.

We are therefore following the research results on quantum computers with great interest ;-)

Energy consumption

All of this is powered by renewable electricity. Currently (12/2025), our machines consume between 1.4 and 2.0 kW (peak load) of electrical power. This corresponds to around one megawatt hour (1,000 kWh) of electricity per month. However, a modern wind turbine (onshore) produces this amount of energy in less than 10 minutes.

In addition, there are costs for the redundant power supply as well as the removal of the resulting heat. All in all, this adds up to a considerable sum. We are all the more pleased that our data center operator (Telehouse) is pursuing innovative concepts for waste heat utilization together with Mainova AG.
