Options for AI & HPC

From companies like Speechmatics leading the field in speech recognition, Instadeep pioneering decision making systems, or our fintech clients undertaking quant research - Kao Data is the perfect home for all manner of AI and HPC workloads:

Technology Suites

Data Centre Racks


Our AI and HPC Technology Suites, all NVIDIA DGX-Ready certified, are designed to support intensive, high density loads of 1100kW or 2200kW. Each format is deployed across either 4,500 or 9,000 sq ft of OCP-Ready, column free, slab-floored technical space. Whether it's racks of up to 40kW air-cooled, or liquid-cooled cabinets supporting Generative AI workloads, we are specialists at industrial scale AI.

  • Concurrently maintainable, Tier 3 equivalent, PUE 1.2
  • Air-cooled or liquid cooled installations
  • ISO certified, NVIDIA DGX-Ready, OCP-Ready
  • All deployments compute modelled using CFD analysis.

Private Cages

Build to suit cage


For rapid growth AI startups, our private cages are perfect for mid-sized (approx 34+ rack) deployments. These can be provided with extra security such as biometric verification locks and CCTV and can be customised with a mix of hardware, densities and cooling methods. All private cages benefit from the same IT environments and associated efficiencies as offered within our Technology Suites.

  • Tier 3 equivalent, concurrently maintainable AI and HPC
  • Dedicated, secure, caged environments
  • ISO certified, OCP-Ready, NVIDIA DGX-Ready
  • Specialist AI and HPC in-house customer implementation.

Individual Racks

Working with our in-house retail colocation partner (ServerChoice) we provide hosting for individual racks, and at varying densities. Unless requested, these are housed at our award-winning KLON-01 data centre on our Harlow campus. Racks are housed within hot-aisle containment formats ensuring efficient cooling, keeping the data hall PUE at 1.2.

  • Quarter, half and full racks - whatever you need
  • Varying power densities, from 1-20 kW
  • Tier 3 equivalent, concurrently maintainable colocation
  • Free hardware relocation and flexible commercial terms.
