Episode 105 - Using AI to build AI, with James Stirrat-Ellis of Build

Data center site selection is a crucial step in the construction process, and picking the right piece of land can be the difference between a project succeeding and failing. For AI data center developers with money burning a hole in their corporate back pockets, separating the promising propositions from duds is a time-consuming business. Build thinks it can help with an AI-powered system that it says can help sift through potential sites to identify the best parcels of land. In this podcast, CEO James Stirrat-Ellis explains how his company's system combines artificial and human intelligence to speed up projects, and how it has worked with the UK government on its much-vaunted AI Growth Zones.

Episode 104 - Re-introducing SDx, with senior editor Ben Wodecki

In April 2025, DCD acquired networking publication SDx, and with it now having been part of the InfraX family for a year, we thought it was about time we sat down with senior editor Ben Wodecki to give the publication a proper introduction. Tune into the episode to meet Ben and hear about what SDx covers, as well as a bit of a discussion on the key upcoming topics you can expect to see on the website.

Episode 103 - Networking at hyperscale with Pradeep Vincent, Oracle Cloud Infrastructure

It can seem like GPUs get all the headlines when it comes to AI workloads, but there are a lot more challenges when it comes to handling massive training jobs. We talk to Pradeep Vincent, Oracle’s Executive Vice President & Chief Technical Architect of OCI, about the importance of power and the oft-overlooked networking in large-scale AI clusters, particularly as we approach multibuilding scale, and potentially multi-campus.

Episode 98 - Insuring uptime with Jonathon Hatzor, Parametrix

That data centers need insurance goes without saying. Any commercial building will typically be insured against standard damages and risks, but data centers are far more complicated than an average warehouse or office. One area that has emerged of late is the idea of “SLA” insurance, or Service Level Agreement insurance. Parametrix is one of the pioneering companies in this realm, and we discuss where the idea came from and why it is growing drastically in popularity.

Bonus episode - Dangerous liaisons with Tommy Schuch, Climber Protection Group

Mobile devices require networks to make them function, and these networks are often deployed in places most people wouldn’t dare to visit, such as telecom towers. Some can be found thousands of miles high, but for tower contractors, it’s their everyday job, and across all sorts of weather conditions. Tommy Schuch, a former tower contractor and now documentary maker and founder of Climber Protection Group, explains the risks of the job to DCD, and why the sector needs a shake-up to protect those risking their lives. Is this the most dangerous job in the world?

Episode 96 - Reinventing the rack, with Iggy Kogan of Air2O

Anyone who has entered a data center will be familiar with the upright rack design that has become standard in data halls around the world. But while piling up the “pizza boxes” has served the industry well for decades, the advent of liquid cooling systems, developed to meet the thermal needs of advanced chips, means a new approach may be needed. Cooling firm Air2O is thinking outside the (pizza) box, and has come up with a modular, stackable design for data center racks, which it says can improve cooling efficiency. On this episode, DCD speaks to Air2O’s Iggy Kogan about the new design, dubbed the High Thermal Density Air-Cooled Rack Assembly.
