Fewer than 15% of traditional colocation facilities in the U.S. can currently support the power density requirements of modern GPU clusters — a gap that catches many AI teams off guard after they’ve already signed a contract. Knowing how to evaluate a colocation provider for AI server deployments before committing is one of the most consequential decisions a compute team will make in 2026.
This guide walks through the specific criteria that distinguish a capable AI colocation partner from a facility that was built for a different era of computing.
Key Takeaways
- AI server deployments require power densities of 20–80+ kW per rack — far beyond the 5–10 kW typical of legacy colocation facilities.
- Cooling infrastructure (liquid vs. air) is a hard technical constraint, not a preference — verify it before signing.
- Network carrier diversity and low-latency interconnects matter significantly for inference workloads.
- SLA terms for AI deployments should address power, cooling, and connectivity separately — not just uptime.
- Scalability path and expansion rights in your contract protect future growth without forced re-migration.
- Physical security, compliance posture, and remote hands capabilities vary widely between providers.
- Working with a vendor-neutral advisor helps avoid being steered toward a facility that doesn’t fit your technical requirements.
What Makes Colocation Evaluation Different for AI Workloads?
Standard colocation evaluation criteria — uptime, physical security, pricing per U — were designed for web servers and storage arrays. AI server deployments, particularly those running NVIDIA H100s, AMD MI300Xs, or similar GPU hardware, operate under fundamentally different constraints.
The core difference is thermal and electrical density. A single 8-GPU server can draw 10–15 kW on its own. A full rack of GPU nodes can exceed 40–80 kW, compared to the 5–10 kW that most legacy colo facilities were engineered to support. When evaluating a colocation provider for AI server deployments, power density per cabinet is the first filter — not the last.
Beyond raw power, GPU workloads generate heat at rates that overwhelm traditional air-cooling architectures. Facilities that haven’t invested in rear-door heat exchangers, in-row cooling, or direct liquid cooling (DLC) loops will either throttle your hardware or force derating that reduces performance. These aren’t edge cases — they’re the primary reason AI teams experience unexpected performance degradation after deployment.
How Do You Assess Power Density and Electrical Infrastructure?
Power availability is the single most constrained resource in U.S. data center markets right now, and it deserves a dedicated line of inquiry with any prospective colocation provider.
When evaluating a facility, ask for the committed kW per cabinet — not the theoretical maximum. Providers will often quote a building’s total capacity, which is meaningless if your specific cage or suite allocation is on a shared power circuit with limited headroom. Key questions to ask include:
- What is the committed power density per rack (in kW)? Get this in writing.
- Is power metered separately, and how is oversubscription managed?
- What is the facility’s available utility capacity, and is there a substation upgrade in progress?
- Are redundant power feeds (A+B) standard, or an add-on?
- What is the generator backup capacity and transfer time?
For teams planning GPU clusters in Texas markets, CoreGrid’s GPU colocation sourcing in Dallas service helps clients verify actual available power allocations — not just what’s listed in a sales deck.
What Cooling Infrastructure Should You Require for GPU Servers?
Cooling is where many AI deployments encounter their first serious operational problem, and it’s the criterion most often glossed over during a standard facility tour.
Air cooling at scale becomes physically inadequate above roughly 20–25 kW per rack. At higher densities, you need one of the following: rear-door heat exchangers (RDHx), in-row cooling units positioned adjacent to high-density racks, or direct liquid cooling (DLC) loops that carry heat away from the chip level. Not every facility offers all three, and some offer none.
When evaluating a colocation provider for AI server deployments, ask specifically:
- Does the facility support rear-door heat exchangers, and are they customer-supplied or facility-provided?
- Is chilled water infrastructure available at the rack level, or only at the room level?
- What is the facility’s Power Usage Effectiveness (PUE) rating, and how is it measured?
- Has the facility previously hosted GPU clusters at comparable density? Can they provide references?
CoreGrid’s liquid-cooling readiness assessments in Dallas-Fort Worth are specifically designed to answer these questions before a client commits to a facility — not after hardware is already racked.
How Should You Compare Colocation Providers on Network Connectivity?
For inference workloads and real-time AI applications, network latency and carrier diversity are operational requirements, not optional upgrades. A facility’s network posture should be evaluated with the same rigor as its power and cooling specs.
| Connectivity Factor | What to Look For |
|---|---|
| Carrier diversity | Minimum 2–3 Tier 1 carriers on-net |
| Cross-connect options | Direct fiber to major cloud on-ramps (AWS, Azure, GCP) |
| Latency to end users | Proximity to major metro population centers |
| BGP routing | Provider-managed or customer-controlled? |
| Dark fiber availability | For private interconnects between sites |
Dallas, as a major internet exchange hub, offers strong carrier diversity — one reason it has become a preferred market for AI inference infrastructure. For a detailed market comparison, the Dallas vs Phoenix for AI Data Center Deployment 2026 guide covers connectivity benchmarks side by side.
What SLA Terms Actually Matter for AI Server Deployments?
Most colocation SLAs were written for traditional IT workloads and default to a single uptime percentage — typically 99.9% or 99.99%. For AI deployments, that number alone is insufficient.
A meaningful SLA for GPU colocation should address:
- Power SLA: Guaranteed power delivery at the committed kW level, with remedies for brownouts or capacity reductions.
- Cooling SLA: Temperature and humidity thresholds within the cage or suite, with defined response times for excursions.
- Network SLA: Packet loss, latency, and availability commitments per carrier, not just “best effort.”
- Remote hands SLA: Response time for on-site technical assistance — critical when your team isn’t local.
- Escalation procedures: Who do you call at 2 a.m. when a PDU trips?
Read the force majeure clauses carefully. Some providers exclude power grid events from SLA remedies entirely — which is a meaningful risk in markets with grid constraints.
How Do You Evaluate Scalability and Contract Flexibility?
AI infrastructure requirements change faster than most other IT workloads. A colocation agreement that locks you into a fixed footprint for three to five years without expansion rights can become a serious operational constraint within 18 months.
When reviewing contract terms, look for:
- Right of first refusal on adjacent cage or suite space.
- Defined expansion pricing — ideally locked to an index rather than market rate at time of expansion.
- Power upgrade path — can you increase your committed kW allocation without re-negotiating the entire agreement?
- Early termination provisions — what are the penalties, and are they proportional?
Teams planning multi-site deployments should also consider how a provider’s footprint maps to their geographic strategy. CoreGrid’s AI data center site selection in Dallas and AI data center site selection in Austin services help clients think through multi-city footprints before signing any single-market agreement.

What Physical Security and Compliance Requirements Apply?
Physical security requirements vary significantly by workload type. Financial services, healthcare, and government-adjacent AI applications often carry compliance obligations — SOC 2 Type II, HIPAA, FedRAMP — that not every colocation facility is equipped to support.
At minimum, evaluate:
- Access control: Biometric + badge + man-trap entry is standard for serious facilities.
- CCTV coverage: 24/7 recording with defined retention periods.
- Audit logging: Who accessed your cage, and when.
- Compliance certifications: SOC 2 Type II is the baseline; ask which auditor conducted it and when it was last renewed.
- Staff vetting: Background check policies for facility technicians with access to your equipment.
If your AI workload handles sensitive data, compliance posture should be a hard filter — not a negotiation point.

Frequently Asked Questions
What power density should I require for a GPU colocation deployment?
Plan for a minimum of 20–40 kW per rack for mixed GPU workloads, and 40–80 kW per rack for dense configurations using current-generation accelerators. Confirm committed power allocation in writing — not theoretical building capacity.
Is liquid cooling required for AI server colocation?
Not always, but it becomes necessary above roughly 20–25 kW per rack. Rear-door heat exchangers or in-row cooling can extend air-cooled viability to moderate densities. For high-density GPU clusters, direct liquid cooling is increasingly standard.
How long does it typically take to evaluate and select a colocation provider?
A thorough evaluation — including site visits, contract review, and technical due diligence — typically takes 6–12 weeks. Rushing this process is one of the most common sources of expensive post-deployment problems.
What is the difference between a Tier III and Tier IV data center for AI workloads?
Tier III facilities offer N+1 redundancy with concurrent maintainability — meaning maintenance can occur without taking systems offline. Tier IV adds fault tolerance, allowing any single failure without impacting operations. Most AI deployments are adequately served by Tier III, though specific workloads may warrant Tier IV.
Should I use a vendor-neutral advisor when evaluating colocation providers?
Yes — colocation providers have strong incentives to present their facilities favorably. A vendor-neutral advisor evaluates options against your specific technical requirements without a financial stake in which provider you choose.
How does Dallas compare to other markets for AI colocation?
Dallas offers strong power availability relative to constrained markets like Northern Virginia, competitive pricing, carrier-neutral interconnection options, and proximity to major enterprise and energy sector clients. It ranks among the top U.S. markets for new AI infrastructure deployments in 2026.
What should I look for in a remote hands agreement?
Look for defined response times (15–30 minutes for critical issues is reasonable), clear scope of what technicians are authorized to do, and escalation procedures for situations that exceed standard remote hands scope. Verify that staff are trained on GPU hardware, not just general IT equipment.
