DCD Zero Downtime: The Bi-Weekly Data Center Show

Data center markets vary wildly by location, and in this episode we head "down under" to the wonderful land of Australia. With the AI boom in full across the globe, Australia is no different and experiencing increased demand.   We talk to David Hirst, who heads up Australia's Macquarie Data Centers, about the trends he is seeing in the country, how Macquarie is approaching AI, and th...

During a natural disaster, networks often go down. This can massively impact rescue missions in some cases. The importance of network operators and the role they play in responding to unpredictable moments is something that should be highlighted. We spoke to Verizon to see how it prepares its response to hurricanes and tornados, and find out the level of training required to support its efforts.

With the cloud market already over-saturated, it is hard to imagine how a new company can make its mark. NexGen Cloud is seeking to do just that, with plans to build a sustainable cloud specializing in HPC and GPU infrastructure called "super cloud." We talk about how NexGen is going to achieve this, the steps taken thus far and why the company thinks it is a solid competitor for some of...

Sourcing adequate amounts of power to run new facilities is a problem that keeps even the most seasoned data center operators awake at night.  Many are looking at new technologies such as battery storage to help meet their power demands, but ensuring these assets operate efficiently can be a challenge. Dublin-based GridBeyond thinks it can help by providing grid-connected battery technologies and...

With AI dramatically driving up density, data center cooling is getting much more interesting.  Iceotope is one of the companies exploring the most efficient and sustainable way to cool down data centers - and their solution is precision cooling. On the face of it, precision cooling resembles immersion cooling - viscous liquid? Check. Bathtub-like container? Check. But as CEO David Craig explains,...

Mushrooms can be used to build more than just toad-stools. In this episode, Joanne Rodriguez, CEO at Mycocycle, talks about using mycelium to break down data center construction waste and make new construction materials. Listen in to this fung-guide to the future of waste management.

Nuclear power may have its detractors, but amid a growing capacity crunch data center operators are becoming increasingly interested in whether atoms can provide the electrons needed to power tomorrow's high-density facilities. In this episode, Chris Lohse of the Idaho National Laboratory, talks about the recent innovations around nuclear power, the highs and lows of recent years, and what the...

Sustainability needs to be applied at all levels of the data center industry, and we are not doing enough, says John Booth of Carbon3IT.  In this episode of Zero Downtime, we sit down with sustainability consultant John Booth to talk about how he got where he is in his career, and the fundamental sustainability issues that he is seeing in the data center industry.  We also talk about a past trip t...

Bringing the L to FLAP-D, the UK has a prominent data center market. But like all other tier-one markets, London is struggling with space and power capacity. Because of this, the UK's data center industry will have to diversify, all while meeting increasingly regimented regulations. In this episode, we talk to trade association TechUK's Luisa Cardani about what the UK's data center ind...

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 cloud is that it takes that integration away,...

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 better on every axis including price, capacity, si...

In this episode of Zero Downtime, we break down the fundamentals of quantum computing - the different approaches out there, the challenges to bringing it into a widespread commercial reality, and the potential use cases that quantum may help with. To help divulge this, we speak to QuEra's Yuval Boger who shares a little about the company's experience with the technology, including how we c...

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 of unrelated websites all went out of action at...

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 in to regulate data centers. Sometimes they want th...

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. He's got 1MW of capacity fed by hydrogen in Mountain View California, and he's telling potential customers he can build the same thing anywhere you can get hydrogen shipped by pipe or tanker.  He's keen...

Ever wonder what it would be like to be a CEO at a telecom company in a country that is at war? That’s been the reality on a couple of occasions for Ineke Botter, who has headed telecom companies in Kosovo and Lebanon.  Her career has taken across Europe and beyond, spanning more than 30 years. She’s even worked in the data center industry too.  Listen to find out more about Ineke’s incredible jou...

The European data center market has a forecasted take-up of 440MW for 2023. But within the context of erratic power availability, moratoriums, and the need to move to renewable energy, the FLAP-D markets are facing several challenges. In this episode we talk to Neal Kalita about the obstacles facing those looking to build in Europe, and what the future holds for the region. Tune in for the convers...

Data centers need to be more sustainable, but finding consistent and powerful energy resources can be a challenge. Increasingly, we are seeing nuclear entering the conversation, in the form of Small Modular Reactors (SMRs). But these aren't without their own controversies. In this episode, we talk with Compass Datacenters' Tony Grayson to discuss the future of SMRs, the challenges and oppo...

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 comparable with that of regular data centers. B...

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 projects. In others (like Denmark and Ireland) they use...

Ever wondered about the practical challenges of connecting our continents? In this podcast episode, we talk with Exa Infrastructure's Elena Badiola about the process of getting subsea cables underwater: from environmental surveys to climate change, to funding challenges. Elena also shares her experience of living on a cable ship for five weeks after an earthquake caused an outage - and how a m...

In 2022, Mark Monroe's podcast about hydrogen was one of our most popular podcasts ever. At Microsoft, Mark had just made a prototype hydrogen fuel cell UPS system that could potentially replace diesel generators to provide low-carbon backup power at data centers. One year on, he's back for some more detail. A hydrogen economy will need a distribution system - but will that look like a pow...

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 say is vague, then your ef...

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 it would destroy your company.   As a leader in th...
