[FAQ]
Frequently asked questions
- What is AI colocation?
- AI colocation means renting cabinet, rack, or hall space inside a third-party datacenter to deploy your own GPU servers. The provider supplies power, cooling, physical security, and network cross-connects.
- How is AI colocation different from a GPU cloud?
- Colocation = you buy and own the GPU servers, the colo supplies the building. GPU clouds rent you the GPUs by the hour. Colo wins on $/GPU-hour at 3-year amortization but requires capex and ops.
- What rack density do AI workloads need?
- Dense H100/H200 nodes draw 40–100 kW/rack; GB200 NVL72 racks draw ~120 kW. Choose colos offering direct-to-chip liquid cooling and 100kW+/rack provisioning.
- Which colos host the largest AI tenancy?
- Equinix, Digital Realty, QTS, Vantage, and STACK host the largest AI tenants — including hyperscalers, neoclouds, and frontier-model labs. See our Top 100 AI Datacenters list for site-level detail.
