High-density data centers in Finland: 5 sites compared

Compare 31 operational Finland data centers across 17 provider. Coloprice separates published cabinet-density and cooling evidence from broad “high-density” marketing claims, so buyers can see what still needs verification before an RFP.

How to shortlist a high-density data center in Finland

All 31 Finland facilities in the current catalog are operational, but disclosed high-density evidence is limited. Equinix HE4 publishes the highest minimum cabinet density in the tracked set at 10 kVA; the other four sites disclose a 3–5 kVA minimum range. That makes HE4 the clearest starting point in this dataset, not proof that a specific hall can support an AI rack.

The current facility records describe air cooling and do not substantiate liquid-cooling availability or an AI-ready designation. Buyers should therefore request hall-level maximum kW per rack, sustained cooling capacity, CDU and water-loop support, power redundancy, available IT load and the commissioning date for any retrofit. Compare responses against one workload profile rather than relying on a provider-wide claim.

Ask for supported kW per rack at both normal and redundant operating conditions.
Confirm whether the quoted density is a minimum cabinet allocation, a design maximum or sustained live capacity.
Verify direct-to-chip or immersion support, CDU ownership, water temperatures and leak-detection responsibility.
Request available IT load and delivery timing for the exact hall; published site MW is not available for the tracked Finland facilities.
Price power, cabinets, cross-connects, setup fees and escalation on the same RFP assumptions.

Finland high-density data center FAQ

Which Finland data center has the highest disclosed cabinet density?

In the current Coloprice dataset, Equinix HE4 has the highest published minimum cabinet density at 10 kVA. The other tracked Finland sites disclose minimum ranges of 3–5 kVA. Buyers still need a hall-level confirmation for their target rack density.

Do Finland data centers support liquid-cooled AI racks?

The current records do not substantiate liquid-cooling support or an AI-ready designation for the five tracked facilities. Ask the operator to confirm the exact hall, maximum sustained kW per rack, CDU arrangement, water loop and deployment date.

How should I compare high-density colocation proposals in Finland?

Send every operator the same rack count, peak and sustained kW, cooling interface, redundancy, connectivity and start-date requirements. Compare available IT load and total contract cost, not only the stated design density.

How we ranked them

Coloprice Score is a 0–100 total of five axes: resilience (tier level weighted by the class of evidence, up to 35), compliance (independent audits, up to 20), transparency (how many of seven key fields are published, up to 20), scale (published MW on a log scale plus liquid cooling and AI readiness, up to 15) and maturity (status and age, up to 10). Every input is a field on the facility card, and every card cites its sources.

Nothing here is opinion or paid placement: an operator can only move up by publishing more data or citing more certificates. A dashed class means the operator disclosed too little for a class to be assigned honestly — the score is still computed.
