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, it is actually a far more efficient solution. Beyond the world of liquid cooling, we talk about political optimism and how the next generation will hopefully help us all towards a greener world.

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, and gives users an easily consumed set of virtual servers and elastic infrastructure. But it costs, and it has pushed users to renting something they would be better off owning. That's why we heard of the "cloud diaspora" - organizations people bringing their IT back from the cloud.
But what people need, Cantrill says, is an elastic infrastructure for the on-premise facility. In this podcast, you can hear him explaining why his team found they had to rebuild almost everything to deliver it.

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, size, and performance. But solid-state providers say it's time they moved over to make way for modern storage. Hard drives have been in a slump, but a new technique promises to double their capacity.
Seagate is the first to bring heat-assisted magnetic recording (HAMR) to the market, so we invited chief commercial officer B S Teh to tell us why it is such a big deal, why it's taken so long - and how it could change what you do in your data center.

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 the same time. It turned out that these sites had all come to rely on the same CDNs, effectively installing a single point of failure for large sections of the Internet.
Since then, large service providers have worked out how to avoid this problem - and one CDN provider told us in a podcast what to do when it does happen.
Major CDN players have extended into a distributed cloud role, running applications at the edge, and Cloudflare, for one, believes CDNs have a huge opportunity in "inference" - when AI pre-trained systems are deployed for actual applications.
2021 also saw the formation of the CDN Alliance, an industry body that aims to be a voice and forum for CDN players, along with the ecosystem that has grown up around them.
Mark de Jong, founder and chair of the CDN Alliance, tells us why CDNs need a voice, and what they need to be saying.

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 them to be greener, sometimes they want them to be quieter, and sometimes they just want them somewhere else. But any data center operator now has to be prepared to meet new reporting requirements and talk to the local authorities about their business.
This is not a bad thing, says Venessa Moffat, head of channel partner manager EMEA Europe for EkkoSense. It's about time those discussions happened.
People who run cities need to understand the businesses that are located there - and from those discussions, new partnerships can emerge.

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 on the benefits. No long waits for power distribution, no struggles getting permits for diesel. And the building is quick and cheap too. He can make them with a 3D concrete printer - which incidentally is environmentally better than tilt-up building, he says.
He picked up the Environmental Impact prize at this year's DCD Awards, and joined the podcast to give us some more details on what he has done.... and what's coming next

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. But the similarities end there, says de Vries, who provided the reliable tracking data for the growth of Bitcoin, and is ready to do the same for AI.
A year ago, he talked us through his methodology for analyzing Bitcoin energy usage. Now he's back, explaining how we can estimate the consumption of AI systems, This time round, it's all about tracking how many GPUs Nvidia can make, and seeing where they are likely to end up.
The actual figure depends on a lot of things, and could be higher if more GPUs emerge, or if they are deployed differently. There are questions around the depreciation of the hardware, and how and where AI inference is delivered.
Listen in to find out how AI's thirst for power is going to affect the world.

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 renewable energy and jeopardize local decarbonization targets.
It's not easy to know the net benefits brought by a data center, because much of what it does is in the virtual world, and is delivered to people far away.
Max Schulze has some thoughts on how to start working out the real benefits of a data center - and we hope for more input from DCD readers and listeners.

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 power network, a gas grid, or a system of trucks?
Data centers won't be the first big users of hydrogen: Mark tells us where it will take off.
This year, we've heard stories of natural hydrogen mined from underground. Mark assesses that prospect, along with the other sources of hydrogen, and suggests that the new energy source could rewrite the world's map of energy providers.
Listen to our talk with Mark to find out where and when you will start using hydrogen.

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 efforts to be sustainable can get misdirected, or diverted into greenwash, or simply end up (like the words) meaningless.
Hunter Vaughan of the University of Cambridge and Nicole Starosielski of the University of California, Berkeley are part of the Sustainable Subsea Network. They are also co-authors of a paper called ICT Environmentalism and the Sustainability Game, which looks at how players like Greenpeace used language to build pressure for green infrastructure.
They spoke to DCD about both: how we communicate about sustainability, and how sustainable our communications systems are.
