RackRenew Turns Decommissioned OCP Hardware into Ready Capacity

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.

Why Remanufacturing is Having a Moment

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.

Standards are the Scaffolding

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.

Trust is the Currency

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.

Where the Demand Shows Up First

Two near-term landing zones stood out in our conversation:

• Fast-growing operators: Clouds, co-locators, and service providers that need to stand up capacity quickly—full racks, network fabrics, and power shelves—without long lead times or greenfield budgets.

• GPU inference and bare-metal providers: Standing up GPU clusters isn’t just GPUs; it’s the rack, the fabric, the power path. Dropping in certified OCP rack-level assemblies lets teams scale faster while keeping performance envelopes predictable.

If we get the ecosystem right, customers get predictable outcomes. And predictable outcomes are the only way circularity shows up in the production SOW.

Circularity With a P&L

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.

The Collaboration Blueprint

Jelle’s outline for how this scales:

• Co-develop take-back protocols with OEMs and hyperscalers.

• Align on software tools, test plans, and recertification criteria.

• Ship with a joint label and warranty that enterprise buyers trust.

• Route eligible material into remanufacturing streams and place it directly into new, standards-compliant builds.

Do that across storage, compute, networking, and power, and the “hundreds of millions” TAM looks conservative.

Quality and Reliability

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.

TechArena Take

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.
