 Just just there you go. So I had the pleasure in early September of going to Helsinki and hosting an open shift commons gathering there And there I saw one of the most exciting things. I know it's kind of geeky but one of the most exciting things I've seen anybody do with open shift and I'm gonna let max Schultz from that and fall go into it, but if this doesn't Make you excited about the potential for doing good with open shift Nothing will so without further ado max. Thank you for coming all the way from Berlin Actually from Amsterdam. Yeah from Amsterdam this time. All right take it and I also want to say thank you Diane for bringing me here I first thought that I will be the last person that fits into this community But now that's actually Chris and and razor. I think what's the name? Yeah They used the word commodity then I feel right at home. Yeah, this is this is exactly what we are all about And I'm sure most of you have no idea what one first. So I will give you a very very brief introduction But infest one of the largest Utilities in Europe is 100% owned by the Swedish state And it's actually one of the biggest providers of renewable energy worldwide. So top 20 Provider and we have of course our largest fleet in Sweden, which is mostly hydropower and nuclear in Germany, we also have coal in the Netherlands gas and We are the biggest builder in Europe right now of new wind assets So we're all about renewable energy and a couple years ago. We changed our purpose To becoming fossil-free in one generation and usually here in the US and also in a lot of European companies This is most of time marketing or strategy people that come up with these sentences in this case is a bit different because this is a Specific order by the Swedish state to completely decarbonize First of all what infights own production portfolio But also all of its customers and all of its customers is quite significant Because in the Nordics alone 90% of all industrial customers are what infile customers And we are for example doing a project with the steel industry to get rid of gas and coal out of steel manufacturing Processes and making them completely free of fossil fuels And When you look at Sweden actually one of the biggest industries and then now we can talk a little bit about more of tech And is the data center industry because Sweden is very cold You have availability of renewable energy and then there's lots of space We actually see almost every single hyperscaler AWS Microsoft Google Facebook they are all coming to Sweden and they're all building data centers of sizes that I don't think even you guys have seen It starts it doesn't end at 300 megawatt size it starts at 300 megawatt size That's about 14 soccer fields of dimensions and they all coming to the Nordics and When they came we started looking a bit more at data centers But before I talk about this I have to bore you a bit because in order for my whole presentation to make sense I have to explain you two things about the energy industry that is important And I try to keep it really short The first trend that you see in the in the energy industry is renewable energy assets So wind solar hydro has been around for quite some time But wind and solar are quite new and they introduce something to the energy system that the energy system is not designed to do Which is volatility all of a sudden I cannot predict and I cannot control the production of energy Which is really really difficult The second trend and we can do a little experiment is decentralization decentralization Decentralization means that all of a sudden your house has a solar panel on its roof And or a battery in the basement or a heat pump or something like this How many of you have an energy system maybe on their house or in their house? Not that many okay, so if you do this in Norway or in Sweden I think like about 80% of the hands go up and This introduces another big challenge because we used to be able to really forecast How you consume power actually if you have a two-family home to two kids at home and a wife I can really forecast your your consumption curve really easily But all of a sudden if you produce your own energy and you produce energy that is again volatile So solar you use your heat pump you maybe you charge your electric car at home you're introducing even more Unpredictability into the energy system and this is important because the energy system and I got the feedback in Finland and in Norway that people didn't actually know this Needs to be 100% stabilized so supply needs to be always exactly matching demand And this is expressed in the energy system with a frequency that is 50 Hertz And this frequency is quite important because if we go one Hertz off all your microwave clocks every clock You have in your house will go about 10 to 15 minutes per day off track Yeah, so a lot of these electrical devices depend on the grid frequency In order to to stabilize this frequency and to make supply meet demand in a world of volatility and renewables We can do two things we can learn how to store energy Which is what you hear Elon alien Musk say a lot that he builds gigantic lithium iron blocks If I show you the cost of these lithium iron blocks and actually how unsustainable these things are You will also say yeah, maybe we should do something else to give you an example when you buy a Tesla You need to drive it for eight years and power it entirely with renewable energy to make the car co2 neutral Yeah, because when you produce the end of the battery you need so much co2 and you you're using so much Minerals that you actually make it at worse So it's a nice story, but it doesn't really work and the other side is we can change how you consume power And now you will think are I already have energy saving light bulbs at home That's not really what I mean, but what I mean is for example, you're washing machine consumes a lot of power What if I can send you a text message and say hey Could you wait an hour until you wash your your load or two hours because then we'll have wind and solar available And that's what we're talking about. This is demand side flexibility or demand response And we actually believe that that will be one of the most important parts of the energy system Now data centers Data centers you can we can have a very long argument here of how much they will grow But I think we can all agree that their growth is needed So we need more digital infrastructure in the future to run your applications to run Whatever deep learning machine learning you want to do and this by the way is without crypto mining before people ask And data centers, they don't just consume any type of power They come to us as a as a utility and they say ideally I would like 100% reliable Uninterrupted power supply and that's great Then we usually agree on five nines or six nines or four nines Yeah, but if you listen to what I just said if we want the world to run on renewables It will be very hard to give you this number Right, it will be almost impossible for me to say I can give you always up power I can do this of course you argue with nuclear sure that works But do we want more nuclear assets around the world probably not I can also do it with hydro in Sweden But in the US there's some hydro assets, but it is very difficult to do this with wind and solar power So we started really looking into data centers and and what what is exciting for us And the first thing we saw when we looked at the power consumption was can we make it more flexible? can we make a data center actually consume power in a more flexible manner and the second thing we Saw and that's actually as an energy utility got us very excited You should have seen our colleagues in the heat department and when they found out that silicon chips Produced 100% co2 free heat So literally a silicon chip content takes power as an input 1 megawatt and makes about 0.99 megawatt in heat. That's if you if you talk to the heat guys This is awesome because it's a very efficient power to heat system and they don't they didn't think about cooling They thought about how can we use this heat? How can we get it out? And the data center operators were very confused. I can tell you that and So in order to to test this we decided that we're going to build a an actual test bed and Now reted will be very happy about what I'm going to say because we first went to them Because we said maybe we can solve this purely on a software side at least the flexibility Topic and they were immediately jumping on board on this not because necessarily they saw an opportunity to make money But because they could really align with our vision to to build a sustainable digital infrastructure Especially in the Nordics where we are all a bit more about sustainability. I would say And they said yes, of course you can do this a bit with open shift You can start moving Kubernetes containers around and we can figure out a way how to make it flexible And we also found some other partners clone heat that does the heat extraction for us. I explain how this works Helio helps us look at compute as a more of a commodity And of course NVIDIA got also very excited because for them cooling these GPUs is actually a big problem So it became they were excited to get rid of the heat And we also defined. Okay. What's the KPI? How do we define a sustainable digital infrastructure and for us it means we reuse 80% of the heat that's a pretty high number and I explained to you how difficult this is and We want power consumption to be flexible So but in order to do this like I said we built two test sites now And we also have a lot of confusion here because I always talk about containers But I mean physical containers because we're building containerized data centers But there's some challenges because when you talk to data center people you're here a lot. They will say, yeah, of course We can give you the heat. It's no problem. We will we will deliver the heat out of the air We extract it and we'll give it to you But they can give it to us at a temperature about 100 degrees Fahrenheit or 40 degrees Celsius, which is useless heat You can just throw it away right away. It doesn't make any sense because you can't transport heat at a temperature So what we need is 60 degrees Celsius or 140 degrees Fahrenheit And in order to get this We have to do two things The first thing is we use water, of course We use liquid cooling technology to get the heat out But we cool the chips not with cold water, but with hot water and we flow the water at such an incredible speed through the data center so that basically The inflow temperature of the data center is 55 degrees Celsius So about 120 degrees Fahrenheit and the outflow is 140 degrees Fahrenheit So you can imagine how fast the water has to run to only heat up by by five Kelvin That's the data that we need And the other thing though if you look at the load curve of a data center And you know that the chip only gets hot when it does something right so you need workloads So a data center doesn't have a flat workload line It is not running at 100 percent capacity all the time if you're lucky it runs at 40 percent So we had to and right now we do this with OpenSec We had to manipulate Actually the workload so so sometimes when we have heat demand in winter where we really need a continuous flow of 60 degrees Celsius We actually ramp up artificial workloads So so we cycle we basically run the CPU on 100% so to make heat and ideally we want to solve this problem by Concentrating workloads on certain machines where we where we can generate the heat And the second problem when it comes to energy flexibility in order to actually make a data center energy flexible You need to physically shut down servers So we because you cannot preserve energy just by shifting the workload You actually need to physically shut down machines and systems so what we started first was to use OpenShift to actually We are telling OpenShift a part of the cluster will go down and then it automatically starts moving containers But then we also integrate really deeply with the UPS systems to actually Remotely turn off the servers Which is a bit trickier But all of this it's it's working now But it's there's there's one last change it works for for artificial workloads So for for HPC or simulations that just need the CPU But the moment so far when we throw a data in and we have some projects internally where we use really large Datasets to forecast certain weather phenomenon for example We're talking about about a petabyte of data that we need to shift around So if I want to do this in a data center, I either need a very big fiber connection or I need to figure out a way how to just Move subsets of data around which is something to be honest that we haven't solved yet And I actually hope that maybe some of you have some input on this and how to solve it because we would love to do it And So when we solve all these challenges what's next for us. It's not a commercial project at all actually for us it's all about Showing the companies that are coming to the Nordics and showing maybe around the world that fossil-free Digital infrastructure as possible that doesn't depend on baseload assets or coal gas nuclear And that the power consumption of a data center can be flexible And when I look at the talk that I this morning about OpenShift version 4 I think A lot of what you're looking at with multi-cloud setups and shifting workloads from different cloud providers Is what we are looking at from an energy perspective in order to basically make the data center more Interactive with the over energy system and make workloads more energy flexible And I think if we can find a way to bring energy utilities I'm a software engineer for me is more logical to bring utilities together with the data center industry and the software people and and really Have them talk to each other I think there's a lot of great things we can do in terms of sustainability I think for utility I can tell you from my own experience now we've been working on this for one and a half years is That they stop thinking about a data center when the cable arrives at the transformer at the power station Yeah, they have no idea what's going on in the data center and they don't care But all of you know that none none of any data center none of the servers are running at 100% capacity You can always shut down a certain part of it But the data center people will say ah, it's too risky Huh, we don't we rather let everything run So there is a mismatch right now and I think we can we can solve this by bringing people together and have them talk to each other Huh? That's it
