During #OCPSummit25, Jeniece Wnorowski of Solidigm and I caught up with Jelle Slenters of RackRenew on how the firm converts retired OCP-compliant racks, servers, switches, power shelves and more into validated rack-level systems, complete with provenance, burn-in, and a joint certification label.
The cloud era taught us to think in fleets. The AI era is forcing us to think in megawatts. In between those realities sits an enormous pool of high-quality, standards-based gear that ages out of hyperscale production far faster than it ages out of usefulness. RackRenew’s thesis is simple: if we standardize the processes for take-back, test, refurbish, and certify—at scale—we can turn retired systems into ready-to-run capacity for the next wave of adopters.
That’s not a niche. As Jelle put it, the total addressable opportunity is in the “hundreds of millions,” and if we truly nail the collaboration across the industry, the upside is “beyond calculation.” The value comes from process: documented, repeatable, and reliable.
OCP is the right place to be talking about this because standards reduce entropy. Common form factors, power and management specs, and known failure modes mean you can design remanufacturing flows that aren’t bespoke for every asset. When you remove variance, you remove cost and time. When you add shared protocols, you add trust.
Enter the OEMs and platform providers. The opportunity is to co-design take-back and recert flows for entire OCP building blocks—racks, servers, switches, power shelves, and harnessing—not just components. That means shared diagnostics, firmware baselines, power/thermal tests, and a joint certification label that signals: remanufactured, validated, and backed by a warranty. That’s what moves circular gear from “nice idea” to procurement-approved infrastructure.
Two near-term landing zones stood out in our conversation:
If we get the ecosystem right, customers get predictable outcomes. And predictable outcomes are the only way circularity shows up in the production SOW.
I love a good sustainability story, but the reason this matters goes beyond sustainability into economics. In an era of equipment scarcity and grid constraints, circular supply unlocks capacity faster and cheaper. That means shorter time to deploy, lower embodied carbon, and better capex efficiency. And because OCP standards reduce integration costs, the savings aren’t swamped by engineering overhead.
Jelle’s outline for how this scales:
Do that across storage, compute, networking, and power, and the “hundreds of millions” TAM looks conservative.
Reliability comes from grading and process: rack-level power and thermal validation, network link integrity checks, server health screening, and repeatable test plans. The result is predictable service-level objectives and clear workload matching—without over-indexing on any single subsystem.
Circularity wins when it delivers new-grade outcomes. The end user shouldn’t have to adjust workloads or expectations because a rack is remanufactured. OCP standards make that possible at scale. The next step is trust infrastructure—joint labels, shared test artifacts, and warranties. RackRenew’s rack-level, certified approach makes circular capacity a practical default for new deployments, unlocking savings, faster turn-ups, and lower embodied carbon.
