Techzine TV podcast
In the Techzine TV podcast we analyze B2B IT solutions, strategies, and trends. IT companies are happy to invite us to talk about what they are working on and what they are going to bring to market. We visit them all around the world, and in some cases, they visit us in our office.
We have a good understanding of how technologies work, or how they should work. We also hear a lot from the market about what companies need or where things go wrong. This gives us the ability to have really in-depth conversations on technology, strategies, and products, but we always try to keep it practical and easy to understand.
We explain innovations, interpret new IT concepts, and use practical examples to make complex technology understandable for everyone. Where necessary, we bring in experts to clarify matters further. The goal is to help IT professionals, decision makers, and other listeners better understand IT developments, but also to help them in their search for new solutions for their business and not get stuck on buzzwords and one-liners.
The Techzine TV podcast is an evolution of the previous Techzine Talks on Tour series. We still bring a lot of conversations and interviews from events to this series. We record so many video interviews nowadays, so we can select the best ones for this podcast series.
The topics still vary greatly, as Coen and Sander attend a total of 50 to 60 events each year, ranging from open-source events like KubeCon to events hosted by Cisco, IBM, Salesforce and ServiceNow, to name only a few. With a lot of experience in many walks of IT life, Coen and Sander always manage to produce an engaging, in-depth discussion on general trends, but also on technology itself.
So follow the Techzine TV podcast and stay in the know. We might just tell you a thing or two you didn't know yet, but which might be very important for your next project or for your organization in general. Stay tuned and follow Techzine TV.

800V DC will power future AI data center infrastructure
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Rob Bunger, Global Director of Data Center Solution Architecture at Schneider Electric, sits down with us to talk about why the industry is moving from traditional 48V AC to 800V DC power distribution for next-generation AI workloads. As AI racks scale from 150kW to potentially 1MW per rack, the current power architecture simply cannot deliver the required density without consuming all available rack space with cabling and power supplies.
The solution involves leveraging 800V DC technology (partly coming from the EV charging industry), deploying power through sidecar systems, and eventually centralized DC distribution. This shift addresses critical challenges including space constraints, safety requirements, and the need for live-swap capabilities in high-density environments. Bunger discusses real-world deployment timelines, with pilot projects expected in 2024, and explains how this represents a fundamental shift in data center power architecture.
Key takeaways:
• Why 48V AC power distribution cannot scale beyond current AI rack densities
• How 800V DC reduces cabling complexity and saves rack space
• The role of sidecar systems in transitioning to DC power
• Safety testing and breaker technology for high-voltage DC systems
• Timeline for commercial deployment of 800V DC infrastructure
