Why CWCS
Secure high-density rack space in Nottingham for AI, GPU, HPC and cloud repatriation workloads. Resilient power, specialist cooling and 24/7 on-site support.
High-density colocation is designed for businesses that own power-intensive hardware and need more power and cooling than a standard rack can provide.
Bring stable workloads back from AWS or Azure for greater control, predictable monthly costs and freedom from unexpected egress charges.
Support research computing, engineering simulations and render farms that need reliable high power over long periods.
Place more compute into fewer racks to reduce occupied space, simplify management and make better use of your power allocation.
Build dense private cloud platforms on hardware you own, with Data Centre power, connectivity and physical security around it.
Move beyond the limits of office power and cooling without giving up control of your equipment or future expansion plans.
Run training, inference and GPU servers in racks designed to support the sustained power and cooling demands of accelerated computing.

Our Beeston facility supports high-density racks with resilient power, carrier-neutral connectivity, controlled access and 24/7 on-site engineers.
Your hardware needs more than rack space. CWCS provides the power, cooling, connectivity, security and experienced UK support needed around demanding infrastructure.
We make colocation simple with a straightforward four step process, from planning your requirements to getting your hardware live.
Tell us your rack size, power, connectivity and preferred UK Data Centre. CWCS will review your requirements and come back with a practical quote.
CWCS colocation security combines ISO certified UK facilities, controlled physical access and named UK Data Centre locations for businesses with compliance and resilience requirements.
Controlled access, CCTV monitoring, access logging and 24/7 on-site procedures protect hardware inside secure colocation facilities.
Your hardware is housed in Nottingham, Manchester or London, giving compliance teams clear UK location evidence for audit reviews.
ISO27001 and ISO 9001 certifications help evidence supplier due diligence, information security controls and quality management standards.
Both services keep your hardware in a secure Data Centre. High-density colocation provides greater rack power and cooling for more demanding equipment.

High-density colocation is data centre rack space for equipment that uses more power and produces more heat than a standard rack. CWCS provides high-density rack colocation with up to 22 kW per 42U rack, supported by resilient power, data centre cooling, connectivity and physical security.
AI colocation gives training and inference systems the rack power, cooling and network connectivity they need while you retain ownership of the hardware. CWCS can house customer-owned AI servers and GPU infrastructure in a secure UK data centre with 24/7 on-site engineering support.
High-density colocation is suitable for AI training and inference, GPU servers, high performance computing, rendering, engineering simulations, dense private cloud and stable workloads moved back from public cloud platforms. We review the equipment and expected server rack power before confirming the design.
HPC colocation provides the power, cooling and connectivity required by high performance computing hardware in a professional data centre. It is commonly used for research computing, engineering simulations, scientific modelling and rendering workloads that need sustained performance from densely configured servers.
CWCS high-density colocation supports up to 22 kW per 42U server rack. The final power allocation and rack design depend on the equipment, expected peak draw and future requirements. We review the server rack power profile before agreeing the deployment.
Our Nottingham data centre uses N+1 chilled-water cooling systems with hot aisle containment. This data centre cooling design removes heat from densely configured racks while maintaining resilience. We review the equipment layout and expected heat output as part of each high-density deployment.
Yes. GPU colocation allows you to place customer-owned GPU servers in a high-density rack for AI, inference, rendering and other accelerated computing workloads. If you would rather rent the hardware, CWCS also provides GPU dedicated servers.
CWCS provides carrier-neutral connectivity with fibre to the rack, access to more than 400 carriers, LINX membership, integrated DDoS protection and connectivity up to 10 Gbps. We agree the network design and any cross-connect requirements before deployment.
You own and manage the colocated hardware, operating systems and software. CWCS provides the rack space, power, cooling, connectivity, DDoS protection and physical data centre security. Our remote hands service can check status lights, power-cycle equipment and connect KVM access for diagnostics.
