Capacity

Describe the workload. We match it to a site and to infrastructure.

A drawn-out server tray, GPU accelerators and direct-to-chip liquid cooling, cabling gathered in gold-ringed bundles — CONCEPT · one row, closed containment, nobody on the floor

This is a scale of physical deployment, not of client maturity. A research group can take a data hall; a corporation can start with a rack.

Five ways to take capacity.

Format	Scale	Site	Hardware	Cooling
Rack / colocation	1 – 20 racks	Quedlinburg	Yours	Air with containment · liquid as a retrofit pathway
Regional AI compute	Up to a data floor	Quedlinburg	Yours or ours	Direct-to-chip
Dedicated AI capacity	Zone to data hall	Campus	Yours	Direct-to-chip
Private enterprise AI	Zone upwards	Either	Yours or ours	Direct-to-chip
Build-to-suit	Building or campus	Campus	Yours	To specification

Future service layer

AI inference

A managed layer for model-token processing, once the underlying capacity is commissioned and the commercial model is settled.

Listed apart on purpose, not as a sixth format. A managed service is a step UP the stack, and what this company engineers are the layers beneath it.

Jurisdiction is fixed when the site is chosen.

Dedicated infrastructure can be configured for data residency within the selected jurisdiction. Where the machines stand, which law reaches them and who may enter the room are design inputs, settled at the same stage as the cooling.
