Oxide Computer has been rebuilding the rack. In this podcast, CTO Bryan Cantrill tells us why. The data center industry has been building its own infrastructure for years, with the wrong components. Servers weren't designed to be operated in data centers, and the 1U rack unit is the wrong size, because of simple science. Part of the success of the …

Think hard drives have hit their storage limits, and should be replaced by solid-state units? You could be wrong. Hard drives have been holding our data for nearly 70 years since IBM created the 350, which stored something like 4 Mbyte on dozens of spinning disks in a unit the size of a washing machine. Today's devices are orders of magnitude bette…

25 years ago, the first content delivery networks (CDNs) emerged, to solve a specific problem - how to make web pages load faster. More than two decades later, 72 percent of Internet content is delivered through CDNs. But the companies involved are still almost invisible - until something goes wrong. In 2021, in a series of outages, large numbers o…

Europe has an Energy Efficiency Directive, Germany has an Energy Efficiency Act, and operators there can be fined for inefficiency. Meanwhile, Amsterdam has declared war on sleeping servers, and set limits on where facilities can be built. Across Europe, in response to congested electric grids and shortages of land, local governments are stepping i…

At the start of 2023, Yuval Bachar told us about his latest project - to build off-grid, hydrogen-powered data centers. As 2023 came to an end, he was back to tell us he'd done it.

Artificial intelligence could grow from almost nothing to using half a percent of the world's electrical power within five years, according to Alex de Vries of Digiconomist. That's a crazy rate of growth, but it's not unprecedented. Bitcoin followed almost exactly the same trajectory, expanding from nothing to a sector whose energy use is comparabl…

We talk to Bill Kleyman, now at machine learning company Neu.ro, about his lengthy data center career. How did he get into the sector, what did he learn at Switch, and how does he balance life and travel? Tune in to find out.

Data centers have outgrown their anonymity. They are large enough consumers of energy and space, that they have to enter the political landscape and justify their existence. But how do we know if a data really brings benefits to its location? In some places (like London), it appears that they soak up grid connection capacity and block housing proje…

Ever wondered about the practical challenges of connecting our continents?

If you want to make infrastructure sustainable, you need to be very careful what words you use. That's what Hunter Vaughan and Nicole Starosielski found, through their involvement in a project to make subsea cables sustainable. Words like "sustainability" and "climate neutral" can mean different things, depending on who is talking. And if what you …

If you think transitioning the tech sector to net zero is all about renewable energy and heat reuse, think again. Small changes in software could make entire data centers redundant - for a much bigger saving for the planet. Green Software is not just about more efficient code, says Anne Currie. Rewriting everything in C might cut energy use - but i…
