HPC Colocation

Sustained rack densities from 4kW air-cooled through to 120kW liquid-cooled, with capacity to deploy immersion zones beyond that range for specific GPU configurations. Each deployment is assessed against the thermal design power of your hardware before contract, so the cooling architecture matches the workload rather than being averaged across the hall.

Not necessarily. Mid-density CPU compute clusters can run on advanced air cooling up to around 20kW to 30kW per rack. Liquid cooling becomes the practical answer above that, and the only realistic answer above 50kW per rack. We run both within the same facility, so HPC deployments can mix cooling tiers based on the hardware mix rather than committing to a single approach.

Both direct-to-chip and full immersion cooling. Direct-to-chip suits deployments that need liquid efficiency at the silicon without changing the form factor of standard rack-mount servers. Immersion suits sustained ultra-high-density workloads above 100kW. Our engineering team reviews your hardware specification and operational requirements before recommending which to use.

Standard GPU-cluster deployments are typically operational within two to six weeks of agreement signature, depending on the cooling tier and the volume of hardware being installed. We hold pre-configured capacity at all UK sites, which removes the lead time associated with greenfield facility builds.

For most organisations, yes. A purpose-built HPC facility involves significant capital expenditure on cooling plant, power infrastructure, and physical security, alongside ongoing operational staff. Our amortises those costs across multiple tenants, charging on a power-based model that lets HPC users pay for the kilowatts they actually consume. Private builds tend to make commercial sense only at hyperscale.
