Colocation · Your hardware in our rack
Your own hardware in our cage at ConnectaPark Düsseldorf. 16 racks, clear prices from €19.90 (€16.72 net) per rack unit, power metered to the watt.
You own hardware that should run reliably — and you have no interest in running it under the desk at home. We operate our own cage with 16 19-inch racks at ConnectaPark Düsseldorf and rent you the space — one to five rack units, whatever you need. Clear prices, power metered to the watt, GPU servers welcome.
What is this?
With colocation you bring your own hardware (or have it delivered) and we provide rack space, power and network connectivity. You keep full control over configuration and software; we take care of the physical infrastructure — cold aisle containment, redundant cooling, UPS- and diesel-backed power, on-site remote hands when needed.
It makes sense when you have specific hardware requirements a standard cloud can't cover: GPU servers, high disk density, exotic operating systems, your own hardware security modules. Or when compliance demands physical control over your hardware. Or simply pragmatic: because you already own hardware and don't want it sitting in the office.
Not a good fit if you really just need a server and don't want to look after an operating system — then Plesk vServer is the better route. Or if you want bare metal without buying hardware yourself — then take a Dedicated Server from us. Colocation is explicitly for people who know what they're doing (or know who to ask).
Location
Our cage sits in a data center at ConnectaPark in the south of Düsseldorf — a carrier-neutral fiber campus right by the A46 and A59 motorways, in the middle of the Rhine-Ruhr economic region, with short paths towards DE-CIX and the Benelux. You reach the location easily by car; your pallets reach it easily by freight.
Cage means: an enclosed, separately secured area with 16 of our own 19-inch racks — entered only by us and by customers we accompany. The building infrastructure (power, cooling, security) is provided by the data-center operator, certified to ISO 9001 and ISO 27001.
Redundant UPS systems buffer every fluctuation; a diesel generator takes over up to 100% of the load on outage — spinning up in around 30 seconds, with monthly function tests and refueling possible during operation. The data center runs on 100% green power from hydro.
Air conditioning via raised floor with redundant precision cooling units (around 50 kW of cooling capacity each), constant supply air at 24 °C ± 2 °C. Our racks additionally sit in cold aisle containment — even temperature across the full rack height.
Entry only via RFID card plus biometric hand scanner, 24/7 video surveillance with long-term archive, alarm system wired to a security service. Solid construction, self-closing doors — and our cage as an additional locked layer behind all of it.
Early fire detection above and below the raised floor — smoldering fires are caught before open flames develop. The antistatic raised floor carries 600 mm panels and keeps cooling and cabling cleanly separated.
Multiply redundant carrier connectivity over diverse fiber routes to the handover points of the major carriers, with redundant, separate building entries. ConnectaPark has grown as a carrier-neutral location — short paths to many networks.
The data-center operation is certified to ISO 9001 and ISO 27001. Located in Germany: your data and hardware sit under German and European law, and you get a data processing agreement per Art. 28 GDPR on request.

All prices include 19% German VAT, net prices shown in small print. Monthly billing, 3-month minimum term for all services (rack plan, service add-ons, IPMI VPN, 24/7 on-call), cancel monthly afterwards (30 days' notice to the end of the month). Power and traffic: see below — this product is additionally governed by our Colocation service agreement.
The hardware you bring in must be 19-inch format (standard servers, switches, rack-mount UPS units). The reason: you share the cabinet with other customers, and deviating form factors break the occupancy logic and the cold aisle containment.
Rack specifications
16 identical 19-inch racks in our cage. These are the specs you plan with:
| Form factor | 19-inch racks, 60 cm wide, lockable |
|---|---|
| Containment | Cold aisle containment — cold supply air at the front, controlled exhaust at the rear |
| Cooling | Redundant precision cooling via raised floor, supply air 24 °C ± 2 °C |
| Power feeds | 4 × 3.6 kW per rack (16 A each) — all four backed by UPS and diesel generator |
| Feed usage | Usable as A+B redundancy or as individual feeds — depending on your setup |
| Maximum power | Up to 14.4 kW per rack if you skip feed redundancy — the cooling for it is there |
| Network | 1 Gbit RJ45 port included per plan · second port or SFP+ uplinks up to 10 Gbit on request |
| Power metering | Every outlet metered electronically 24/7, billed to the watt |
Cost calculator
Pick a size, enter your planned average power draw and bandwidth — you see immediately what you pay per month, with and without VAT.
Quick picks for common hardware:
Billed 95/5: spikes are dropped, what counts is the sustained load. A quiet web server often sits at 5–15 Mbit/s, a well-visited portal at 25–50 Mbit/s.
Includes 19% German VAT. Service add-ons not included. Power and traffic vary with your usage — the customer center shows both curves day by day.

Power billing
We don't bill power as a flat rate per outlet (that would overcharge you at low draw) and not per kWh either (legally that would be electricity trading and require a utility license we don't have — and that isn't worth the paperwork to us). Instead: every one of your outlets is metered electronically around the clock. From these 24/7 readings we compute the monthly average — and that's the basis we bill on.
per watt of average monthly draw (includes 19% German VAT, €0.3277 net) · equals €390/kW (€327.73 net)
Example calculation for Düsseldorf (€0.39/W, includes 19% German VAT). Net values in parentheses.
| Hardware | W avg. | per month |
|---|---|---|
| 1U server, frugal (Intel Atom class) | 75 W | €29.25 €24.58 net |
| 1U server, standard (Intel Xeon) | 200 W | €78 €65.55 net |
| 2U server with a few HDDs | 350 W | €136.50 €114.71 net |
| GPU server (2 × GPU, AI/rendering) | 800 W | €312 €262.18 net |
| Fully populated rack (assumption) | 1500 W | €585 €491.60 net |
Example calculations, rounded. Your draw is visible day by day in the customer center — so you can check at any time what efficiency tweaks (CPU frequency, disk spindown, fan curves) actually do to your power bill.
Network & traffic
Every plan comes with one 1 Gbit RJ45 port included. A second port or SFP+ uplinks (fiber) with up to 10 Gbit are available on request — open a ticket and we'll sort it out.
We bill traffic using the industry-standard 95/5 method (also known as 95th percentile billing): we measure your bandwidth usage continuously in 5-minute intervals — inbound and outbound. At the end of the month the top 5% of all readings are discarded, so short load spikes cost you nothing. The highest remaining value is your billed bandwidth in Mbit/s.
Example: your server serves calm web traffic all month, the 95th percentile lands at 25 Mbit/s → 25 × €2.38 = €59.50 (€50.00 net) for the month.

What's in the plan
60 cm standard cabinets in a closed cold-aisle architecture — cold supply air flows directly to the hardware front, exhaust at the rear is removed in a controlled way. Even temperatures for every rack unit, in each of the 16 racks.
Four independent 16 A feeds per rack, each fully backed by UPS and diesel generator. Usable as A+B redundancy or as individual feeds. Skip the redundancy and you can draw up to 14.4 kW per rack — GPU setups included.
Every outlet is recorded electronically around the clock. From the 24/7 readings we compute the monthly average in watts and pass the energy cost on proportionally — plus a small metering surcharge. Six months of minute-level history in the customer center.
Our 16 racks sit in an enclosed, separately secured cage area. Access happens accompanied by a xaweho team member, by prior appointment — typically within 24 hours.
We usually handle remote-hands tickets within a few hours during business hours. Outside of them with the booked 24/7 on-call service — nights, weekends and public holidays included.
We filter volumetric attacks away at the network level. Filtered attack traffic doesn't count toward your 95/5 readings. For specific application-layer attacks, talk to us.
You control the PTR records of your IPs yourself via the customer center. Important for mail servers, clean for any application with outbound connections.
The location is in Düsseldorf. That puts your data under German and European law. Data processing agreement on request, no subprocessor acrobatics.
Services & add-ons
The rack space itself we pass on at a slim margin — good prices come from efficient purchasing and long-term planning of rack occupancy. Service work you book as needed, at clear prices.
per 15 minutes · Mon–Fri 9:00–18:00
Hardware reboot, status check, cable inspection, small interventions. Request by ticket, usually handled within a few hours.
per 15 minutes · evenings, nights, weekends, public holidays
Same work as during business hours, at a higher rate for the on-call overhead. Requires the 24/7 emergency on-call service (see below).
one-time
You ship the hardware to our location — we unpack, rack it cleanly, cable it, power it on, assign IPs and let you know as soon as your system is online. Saves you the trip.
monthly · plus separately metered power
One power circuit is standard. With A+B redundancy your hardware hangs on two independent feeds, each UPS- and diesel-backed (one PSU per feed in the server). If one source fails: no reboot.
monthly
We put your IPMI/iDRAC/iLO interface into a dedicated management network with an internal IP. You reach it remotely via VPN without having to expose the management interface publicly.
monthly · required for remote hands out of hours
Reachable via emergency line outside business hours. Without this booking, remote hands run Mon–Fri 9:00–18:00 only. The actual interventions are billed on top by effort.
monthly · plus one-time setup
Single IPs or whole subnets from /29 to /24, bookable anytime — prices in the table in the network section. Availability depends on RIPE; for larger needs, talk to us first.
individual
We keep a spare part of yours on site so it can be swapped immediately on failure. You save the trip, we save you the downtime.
Who uses this
You've hosted things yourself so far (an office rack or an aging colo contract) and want out of the hosting stress. Your hardware is solid — only the location should get better. We take it in, and you skip buying new gear.
You run GPU servers for training, inference or rendering — and at home or in the office, power and cooling don't cut it. With us: up to 14.4 kW per rack, cold aisle containment, power billed to the watt. And you save yourself the cloud GPU rent.
You look after customers whose hardware sits at your place or in their office. We house it for you at a professional location, and you stay the point of contact for your customers — resell the service with a markup.
For audit or insurance reasons you need physical control over specific hardware (an HSM, your own backup storage). Cloud is off the table. We give you a lockable rack with an access log — in an ISO 27001-certified data center.
You run game server clusters and need to add hardware as demand grows. With a rack you have room to grow without ordering every new system individually. CPU and SSD entirely your choice.
Your setup at home has grown and it shows: fan noise, heat in the living room, the power bill, security questions. A few rack units with us solve all of that at once — and depending on your power draw, cost less than the socket at home.
What sets us apart
We operate our own enclosed cage area with 16 racks — so we plan occupancy, power and network ourselves and give you prices that are remarkably low for this industry. From €19.90 (€16.72 net) per rack unit, no asterisk games.
Flat-rate outlet models are unfair to efficient hardware: you pay what a maximum-draw machine would cost. With us: metered usage, passed on with a small metering surcharge. Frugal hardware actually saves you money — and the readings are visible six months back.
No traffic packages, no throttling: we bill by the 95th percentile, the same way carriers and data centers settle among themselves. Load spikes drop out, and you pay for the bandwidth you actually use — €2.38 per Mbit/s (€2.00 net).
We have a dedicated service agreement (SVB) for colocation that states concretely what we deliver and what you deliver as the customer. No clauses hidden in the small print.
When you request remote hands, someone from the team answers who knows what they're doing. Three people, long experience with rack setups, cabling and network debugging. No escalation loop.
Dell, HPE, Supermicro, Lenovo, Synology, GPU servers, your own home-built gear — no vendor lock-in. As long as it fits the 19-inch format and is electrically sound, it's welcome.
Setup
Open a ticket with your requirements: desired rack size, planned power draw (a rough estimate is fine), special needs (A+B redundancy, SFP+, IPMI VPN, 24/7 on-call, GPU setup). We come back with an availability check and a quote.
After confirmation you receive the contract documents, SVB references and credentials for the customer center. We reserve the rack position, assign IPv4 and IPv6 and prepare the power circuit.
Three ways: (a) You come by at an agreed time and a xaweho team member accompanies you during installation (the standard). (b) You send the hardware by freight, we receive it and confirm arrival. (c) Book the onboarding service — we unpack, rack, cable, power on and report your system online. That last one is the fast lane.
You get the network details from us (IPv4, IPv6, gateway, netmask) and configure your hardware with them in advance — then it's reachable right after being plugged in.
As soon as you're powered on, you see your average power draw in the customer center — with six months of history. The usage trend helps with capacity planning and hardware efficiency tuning.
You manage your hardware as usual. For physical work you book an accompanied visit or remote hands. For network topics you open a ticket. Power and traffic usage stay transparently visible at all times.
