Large training and inference workloads can also demand much more power, heat removal, data movement and storage throughput than a conventional facility was designed to deliver. The right answer is not always a new building: an existing site may support selected AI workloads if its electrical, cooling and network capacity—and its room to expand—match the job.
Why can’t a data center just add AI accelerators?
Accelerators do the computation, but they cannot perform well in isolation. They need dependable power, a way to remove the resulting heat, fast connections to other accelerators and a steady supply of data. If any of those supporting systems becomes a bottleneck, adding more compute does not solve the underlying constraint.

This is why AI infrastructure is a systems-design problem. The compute choice affects power demand and heat; the cooling approach affects facility design; the workload’s communication pattern affects networking and storage; and all of those choices shape how easily the site can grow. A facility with spare floor space but insufficient utility power or heat-rejection capacity may be a worse fit than a smaller site with more suitable infrastructure.

Training: keep accelerators exchanging data
Large training workloads distribute computation across many accelerators. Those devices must exchange data, so the network connecting them—the east-west traffic within the facility—can be as important as the computing hardware. Network bandwidth and latency, plus the throughput of the storage feeding the job, help determine whether accelerators can stay productively supplied with data.

Inference: consider response time and user location
Inference runs a trained model to produce an output. Depending on the service, the priority may be delivering a response quickly and placing capacity close to the people or systems making requests. That can make latency and site location especially important. A design optimized for a large, tightly connected training cluster is not automatically the best design for a geographically distributed inference service.
Why do AI data centers need different power and cooling?
Dense accelerator deployments concentrate electrical demand and heat in racks. McKinsey & Company reported in an October 2024 analysis that average data-center rack power density had more than doubled over the preceding two years, from 8 kW to 17 kW, and projected it could reach 30 kW by 2027 as AI workloads increased. Those figures describe the analysis and its projection, not a current measurement of every data center.

- Hassle-free Installation: Fully adjustable square-hole mounting rails of the wall mount server cabinet facilitate device installation. Wiring holes on the top, bottom, and rear panels provide you with easy cable routing.
Power delivery and heat removal have to be planned together. A cooling system’s capacity is relevant only if the facility can deliver the required power and reject the heat it removes; likewise, available electrical capacity is not useful for a dense deployment if the cooling system cannot handle its thermal load. McKinsey describes several cooling approaches and the rack-density ranges associated with them in its 2024 analysis:
Recommended Free Tools
| Cooling approach | Density discussed by McKinsey | What to keep in mind |
|---|---|---|
| Rear-door heat exchangers | 40–60 kW per rack | McKinsey’s stated range; capability depends on implementation. |
| Direct-to-chip cooling | 60–120 kW per rack | Described as commonly deployed in McKinsey’s account; actual capability depends on implementation. |
| Immersion cooling | Around 100 kW per rack; above 150 kW for dual-phase use | Ranges described by McKinsey; actual capability depends on implementation. |
These are not universal limits or guarantees for a particular installation. The workable choice depends on the equipment, facility design and deployment conditions. Liquid cooling is therefore not a single solution that every AI site must adopt; it is a family of approaches to evaluate against the heat load and the rest of the facility.

Can a traditional data center be retrofitted for AI?
Sometimes. A retrofit can make sense for a selective workload when the building has enough power, cooling, network and storage headroom, or when those systems can be upgraded on a practical schedule. Floor space alone does not establish suitability. The important question is whether the facility can support the expected workload at the required density and continue to do so as it expands.
Peter Panfil, Vertiv distinguished engineer and vice president of technical business development, told Mouser Electronics in a July 24, 2026 article that “many existing facilities can be upgraded to support selective AI workloads, but purpose-built designs are usually better suited.” This is an attributed industry perspective, not a universal engineering standard; the facility and workload determine the answer.

Use the workload and site together to assess fit
| Decision area | Questions to answer |
|---|---|
| Workload | Is the site intended for training, inference or both? What communication and response-time requirements follow from that choice? |
| Rack density | What power density will the planned equipment require, and can the cooling design support it? |
| Power | Can utility service and backup power support the deployment and its planned growth? |
| Heat rejection | Can the facility remove the heat at the intended density using a cooling method suited to the site? |
| Networking and storage | Can the network provide the bandwidth and latency the workload needs, and can storage deliver data quickly enough? |
| Schedule and expansion | Can required upgrades be completed in time, and is there a credible path to add capacity later? |
If one or more critical systems cannot meet the workload’s needs, the choice is not simply “retrofit” or “new build.” The operator may be able to change the scale or type of workload, upgrade the constrained system, or choose a site designed for the target capacity. The trade-off is between making use of existing infrastructure and the coordination, time and cost of bringing every necessary system into alignment.

NVIDIA’s May 20, 2025 developer blog describes a proposed 800 VDC power architecture aimed at future megawatt-scale racks. NVIDIA says the design could transmit 85% more power through the same conductor size, reduce copper requirements by 45% compared with 415 VAC distribution, and improve end-to-end efficiency by up to 5%. These are vendor-stated benefits for a proposed architecture, not independently validated results or evidence of broad deployment.
NVIDIA said full-scale production was expected to coincide with its Kyber rack-scale systems in 2027. As of October 2026, that is a future roadmap milestone. The company’s account also identifies safety, standards and workforce challenges. A higher-voltage architecture is not simply a drop-in upgrade: facilities would need to address those practical requirements as part of any deployment decision.
What makes a data center AI-ready?
AI readiness is not a label that follows from installing accelerators. It means that the facility’s compute, electrical supply, cooling, network, storage and operational plans can support a defined workload at its intended scale. Some existing sites may satisfy that test for selected deployments; denser or larger clusters may make purpose-built infrastructure a better fit.
