GPU racks draw power at a rate that simply was not on the roadmap for most facilities built even five years ago, which is why power delivery — not floor space — is now the binding constraint.
Ask ten infrastructure leaders how they choose a data center and you will get ten different answers. Yet beneath the variety, the same handful of questions tend to decide the outcome.
Why it matters now
Power has overtaken floor space as the binding constraint in most primary markets. Vacancy rates have fallen to record lows, and the practical effect is that capacity — particularly high-density capacity — increasingly needs to be reserved well ahead of when you actually need it.
The market has split in two. Standard enterprise workloads still run comfortably at three to five kilowatts a rack, while accelerated-compute deployments are pushing twenty, fifty, even a hundred kilowatts. Those two worlds are priced and provisioned very differently, and conflating them is a common and expensive mistake.
The factors that actually move the needle
Connectivity richness is frequently underweighted. A carrier-neutral facility with a dense ecosystem of networks and direct cloud on-ramps can save more over a contract term than a modest difference in the rack rate ever will.
Tier classification tells you what a facility was designed to do, not how well it is run. A well-operated Tier III site routinely outperforms a poorly managed Tier IV one on the metric that matters: real-world availability.
Planning for what comes next
Term length is a lever worth pulling thoughtfully. Longer commitments unlock materially better rates and, increasingly, priority access to scarce capacity — but only commit ahead if you are confident in the trajectory.
Whatever you commit to today, leave yourself room to grow. The right partner offers a clear path from a single rack to a private suite, and from standard density to liquid-cooled high-density halls, without forcing a migration.
What good looks like in practice
Good facilities make the boring things boring: predictable billing, clear escalation paths, and remote-hands requests that get done on the timeline promised, not the timeline hoped for.
The best partnerships look less like a vendor relationship and more like a shared roadmap — regular capacity reviews, early visibility into expansion options, and a provider that flags risk before it becomes your problem.
A short checklist before you sign
- Ask for real uptime history, not just the design tier
- Total the full cost of ownership, including the fees that hide in the small print
- Leave headroom for growth, including higher-density racks down the line
- Confirm the certifications your industry and customers actually require
- Clarify remote-hands response times and what is included versus billed separately
The bottom line
There is no shortcut that replaces doing the homework, but there is a real payoff for doing it well: fewer surprises, better terms, and a partner that fits for the long run.
