Your servers do not belong in the utility room next to the office kitchen. Move your hardware into a professional data centre - with redundant power, DE-CIX connectivity and our engineers in the same building. From €49.90 per rack unit per month.
colocation
Colocation means you keep your own servers and we provide the environment. Instead of a utility room in your office, your hardware sits in an ISO 27001 certified data centre in Düsseldorf - with redundant power, professional cooling and network connectivity you could never achieve on your own premises.
who it suits
Four typical situations - and what colocation solves in each of them.
No more utility room, no air conditioning that gives up in summer, no UPS that nobody ever tests. Your hardware sits in an environment built exactly for it.
Space for customer systems, growing with you from a single rack unit to your own rack. Remote hands takes over whenever you would rather not travel yourself.
When the monthly cloud bill has long overtaken the depreciation on your own hardware, owning it pays off again. We provide the environment for it.
You know at all times where your data sits - and you can go and look at it. ISO 27001, located in Germany, data processing agreement under GDPR.
space required
You only pay for what you actually need - and you can grow at any time. We calculate the exact price based on space, power and connectivity.
Your own enclosed section for smaller setups.
The step up to your own rack section.
Enough space for virtualisation, storage and backup.
The complete rack, exclusively yours - or several if you need them.
All racks are 600 mm wide, with your own lock and access around the clock. Price guaranteed for 12 months from a single rack unit, and for 24 months on shared and full racks. Larger setups - several racks or your own cage - are planned individually.

engineers on site
At the large data centre operators every single task is a ticket with a minimum charge. Not with us: oneCorp keeps its own office right inside the Düsseldorf data centre.
As a colocation customer, 15 minutes of basic remote hands per month are included in your contract - reboots, status checks, re-plugging cables. No extra charge. If you need more, such as hardware replacement, installation or cabling, our remote hands team takes over at fixed hourly rates.
15 minutes of basic remote hands per month: reboot, status check, re-plug cables, visual inspection.
Hardware replacement, installing new systems, cabling, media conversion - at fixed hourly rates.
We keep power supplies, drives and memory in stock on site. On request we store dedicated spare parts directly in your rack.
You will find more on services, rates and response times on our Remote Hands page.
how it works
From the first enquiry to live operation - in five steps, with no surprises.
How many rack units, how much power, which connectivity? We go through your setup together.
Optional but recommended: come and see beforehand where your hardware will be standing.
You receive a fixed quote. Once accepted, we reserve your space in the data centre
You deliver and install yourself - or our team handles transport, installation and cabling.
Access around the clock, remote hands when needed, a named contact with a direct line.
From the first conversation to a live rack usually takes two to four weeks - depending on how quickly your hardware is ready.
comparison
What changes when your hardware moves out of your own utility room and into a professional data centre.
And the cloud? Public cloud pays off when load fluctuates heavily and you do not want to own hardware. As soon as utilisation becomes predictable, your own hardware in a data centre is usually considerably cheaper - with full data sovereignty. We are happy to work through both options with you.
