Data Center Colocation
Colocate OCP hardware in our partner data center to maximize performance, efficiency, and availability.
Many organizations need maximum power and efficiency without the cost and complexity of building and maintaining a data center.
Based at maincubes Amsterdam, the only OCP Ready™ data center in Europe, colocation provides all the benefits of hyperscale hardware with none of the complexity. We’ll design your infrastructure from the ground up so it supports your most demanding workloads while reducing costs.
Need to connect with other data centers and existing platforms? No problem. We provide a full range of connectivity options, including 1-100GbE network connections, data center interconnect, cloud on-ramps, and dark fiber.

Circle B Helps Your Enterprise…
Boost Performance
Power your most demanding workloads with hardware designed by (and for) hyperscale companies like Facebook and Google.
Not sure what to expect? See your workloads in action before you buy at our OCP Experience Center, based at maincubes Amsterdam. Remote and in-person demonstrations available.
Reduce TCO
Our hardware uses 21” OCP racks, which are more energy efficient than standard 19” racks. This produces less heat, lengthens hardware lifespan, and reduces ongoing costs.
The modular design of our OCP solutions also dramatically simplifies maintenance, enabling one technician to manage far more servers than with 19” racks.
Control Security & Compliance
Standard servers typically come with black box firmware, locking you into using specific brands for memory and other components. Even worse, this firmware prevents you from having total control of your servers.
Our servers are 100% free from black box firmware, giving you full control of infrastructure at every level and enabling your security team to protect system integrity and data privacy.
Minimize Downtime
High availability is critical to modern organizations, particularly those that rely on digital infrastructure for revenue.
Our solutions combine hyperscale hardware with rack and white space design that reduces heat and wear on components. This minimizes the risk of hardware failure, protecting against costly downtime incidents.
Scale Rapidly to Meet Business Needs
Our modular OCP solutions make scaling your infrastructure the easiest it has ever been.
Add or replace servers and components, rebuild racks, and expand as needed—and requisition anything you need on-demand through Circle B.
Minimize Your Carbon Footprint
For many enterprises, sustainability has become a critical business need.
Our solutions are designed for maximum energy efficiency and heat reduction, helping you minimize your carbon footprint and hit sustainability targets.
Why Do We Use OCP Hardware?
Way back in 2009, Facebook realized there was a better way to design data centers. Everything from servers and components to racks and white space was made more efficient, scalable, and cheaper to run. By 2011, other hyperscalers like Google and Intel were already onboard.
All our colocation solutions are based on OCP hardware for the simple reason that it’s head and shoulders above everything else on the market. Our partner data center is the only one in Europe to be certified OCP™ Ready, so we can exclusively offer enterprise-ready colocation solutions that rival those used by the tech giants.
