Chiplets aren't just a trend anymore, they're becoming the default architecture for the AI era. But as the industry stacks more dies into a single package to keep up with AI and HPC demands, it's inheriting a reliability problem nobody has fully solved: when four, eight, or more dies from different processes (and sometimes different vendors) share one package, a single weak link can disqualify the entire stack — and the cost of that failure is enormous.

In this episode, OCP's Rob Coyle sits down with Evelyn Landman, co-founder and CTO of proteanTecs, to unpack why "known-good-die" testing is no longer enough and what it actually takes to reach "known-good-stack" confidence. They get into the hidden risks of multi-die packaging — thermal coupling, voltage droop, mechanical stress from through-silicon vias, and interface faults that traditional pass/fail testing simply can't catch — and how embedded telemetry is giving engineers real visibility inside the package, from bring-up and debug all the way through in-field operation.

What if the biggest constraint on the AI era isn't compute power, software, or even money, it's how we cool the hardware that runs it all? In this episode, Rob Coyle sits down with Jean-Marc Denis, Chief Product Officer at Submer, to explore why immersion cooling has gone from an exotic idea in a Barcelona garage eleven years ago to what many believe will be the dominant cooling paradigm for AI infrastructure. 

Jean-Marc brings nearly 40 years of high-performance computing experience — from designing supercomputers to founding the European Processor Initiative — to a sweeping conversation about intelligence per watt, the power and water constraints reshaping data center strategy, and why the real money in AI is not in training mega-models but in inference at the edge.

This episode covers both the technical and business dimensions of the AI infrastructure buildout, including why the six-month land-to-first-token expectation is forcing a co-design revolution, and how immersion cooling's simplicity — not its complexity — may be its most underrated advantage.

Every AI server rack deployed in a data center must pass electromagnetic compliance (EMC) testing before it can go live - it is a legal, regulatory requirement enforced by the FCC. But as AI hardware scales to megawatt-class racks with disaggregated compute, power, and liquid cooling systems, the test labs responsible for certifying that hardware are falling dangerously behind. There are only one or two labs in the world currently capable of handling the size, weight, and power demands of today's AI rack configurations - and the gap is widening with every new product generation.

In this episode, Jaswanth Vutukury - Lead EMC AI Hardware Infrastructure Engineer at Meta - joins host Rob Coyle to break down exactly why this bottleneck exists, what it means for hyperscalers and ODMs trying to bring next-gen AI infrastructure online, and why he is using the OCP podcast as a call to action: for test labs to join the OCP ecosystem, for hyperscalers to begin collaborating on the problem, and for the industry to explore alternatives to traditional testing before this becomes a hard stop on AI deployment.

In this second installment of the Women in OCP series, host Rob Coyle goes deeper with Shruti Sethi, Sr. Product Manager on Azure Storage at Microsoft, OCP Sustainability Steering Committee rep, and Women in OCP Co-Lead. 

Where Part 1 covered the founding and structure of the group, this conversation digs into the harder questions: the real challenges the initiative faces, how it measures progress, what it will take to scale, and, critically, why male allies and non-women supporters are not just welcome, but essential. Shruti's perspective bridges her sustainability work with Microsoft Azure and her leadership at Women in OCP, making this a rich and candid conversation about what meaningful inclusion actually looks like in the data center industry.

In this episode, host Rob Coyle sits down with Sung Kim, Global Head of Technology for Data Center Liquid Solutions at bp Castrol and Co-Lead of Women in OCP, to discuss how a simple observation at an OCP summit sparked a thriving initiative that is reshaping how women are represented across the data center industry.

From founding the Women in OCP group to hosting its first Women and AI luncheon co-sponsored by Nvidia and Lenovo, Sung shares the journey, the challenges, and the collective energy that is driving real change at the industry level.

Rob Coyle sits down with David Hirst, CEO of Macquarie Data Centres, for a deep look at the rapid changes shaping data centers in the age of AI. David shares why Australia’s sovereign approach matters, how AI workloads are shifting design from “real estate” to “chip-out thinking,” and why early collaboration across hyperscalers, government, and the supply chain is becoming essential.

They explore the unique nature of the Australian market, the rise of liquid cooling and megawatt-per-rack designs, what it takes to build IC3 Super West, and how culture, regulation, and geopolitics all influence where and how AI infrastructure gets built.

A thoughtful conversation for anyone working in AI infrastructure, colocation, hyperscale strategy, or global data centre planning.

Texas Instruments is known for semiconductors, calculators, and decades of design expertise. In this episode, Chris Suchoski shows how TI is becoming a full grid-to-chip partner for the next wave of data center growth. Rob and Chris break down what it takes to power AI, how architectures are shifting, and why TI’s deep experience outside the four walls of the data center matters now more than ever.

Chris outlines the pressure facing the industry. AI workloads are growing at a rate the traditional design cycle cannot match. Time-to-market has gone from years to months, yet the expectations for density, power, sustainability, and reliability continue to climb. TI’s response is to support the entire power path from the grid to the GPU. Their goal is to help customers move faster and build systems that can take on the new wave of compute demand.

They discuss the shift from conventional rack design to high-voltage architectures like 800V, the rise of megawatt-class racks, and what happens when unpredictable AI workloads collide with an aging set of power assumptions. Chris explains why this shift impacts every part of the ecosystem, from AC distribution to cooling to storage systems. He also talks through how TI’s decades of work in automotive, industrial, and grid power translate directly into the needs of hyperscale and AI operators.

The conversation also highlights how collaboration through OCP speeds progress. Standards development, shared learning, and early visibility into architectural trends help companies build aligned solutions. Chris explains why TI participates heavily in OCP working groups and why he sees it as one of the best ways for operators and engineers to keep up with rapid change.

AI clusters are exploding in size and pushing the limits of today’s data center power and network designs. In this episode, host Rob Coyle sits down with JP Buzzell, VP and Data Center Chief Architect at Eaton, to break down why power architecture has become the next big bottleneck and how the industry can respond.

JP explains how data center design has hit a turning point. Density jumped from a few kilowatts a rack to more than 100 kW almost overnight. The move from many small, varied workloads to massive, synchronized GPU clusters has changed everything from physical layouts to network physics. Packet loss now dictates rack layout. Space inside the rack has run out. Cooling had to evolve not just for efficiency, but simply to fit the gear. And power distribution needs a complete rethink.

The conversation covers the shift toward direct current power, why AC inside the rack cannot scale to the clusters coming next, and the role OCP is playing in driving standards, regulation, and cross-industry cooperation. JP also shares the human motivation behind this work, from medical breakthroughs to a cleaner, safer grid.

This is a clear and practical explanation of a topic that will shape the future of data centers for years to come.

Nabeel Mahmood returns to the OCP Global Summit — and the OCP Podcast — with momentum, mission, and a message. In this follow-up conversation with host Rob Coyle, Nabeel shares the growth of Nomad Futurist’s education efforts, bringing students and new voices to the forefront of the data center ecosystem.

The episode dives deep into why building the future of infrastructure starts with people, access, and understanding. From debunking misconceptions about data centers to spotlighting programs supporting students in underserved regions, Rob and Nabeel explore the true meaning of open innovation and industry responsibility.

In this special episode of the Open Compute Project Podcast, host Rob Coyle sits down with Bill Carter, Fellow Emeritus and former CTO of the OCP Foundation, for a deep and personal conversation spanning the entire history of OCP - from its scrappy beginnings to its position today as a force in global infrastructure innovation.
