Case Study Vattenfall Sustainable Data Centers, OpenShift on OpenStack

[Music] you justest there we 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 infall 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 for MEMS to them they're from Amsterdam this time all right ticket and I also want to say Thank You Diane for bringing me here I first thought that I would be the last person that fits into this community but now that actually Chris and and Raisa I think what's the name yeah they used to what 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 1/5 so I will give you a very very brief introduction button first one of the largest utilities in Europe missed one one percent 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 called 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 a small time marketing or strategy people that come up with these sentences in this case it's a bit different because this is a specific order by the Swedish state to completely decarbonize first of all button-fly its own production put for you 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 one fire customers and we 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 it's the data center industry because Sweden is very cold you have availability of renewable energy then there's lots of space we actually see almost every single hyperscale 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 actually under mega websites that's about 14 soccer fields of dimensions and they're 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 boy 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'll try to keep it really short the first trend that you see in live in 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 its decentralization decentralization means that all of a sudden your house has a solar panel on its roof and were 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 ok 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 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 your charge your electric car at home 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 no way that people didn't actually know this needs to be 100% stabilized so supplier 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 1 Hertz off or your microwave clocks every clock you have in your house will go about 10 to 15 minutes per day off track so a lot of these electrical devices depend on the grid frequency in order 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 in an alien mask 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 well 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 now because when you produce the end of the battery you need so much co2 and 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 think I already have energy-saving lightbulbs at home that's not really what I mean but what I mean is for example your washing machine consumes a lot of power what if I can send you text message and say hey could you wait an hour until you wash 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 there 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 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 in data centers they don't just consume any type of power they come to us as a utility and they say ideally I would like 100% reliable uninterrupted power supply 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 yeah 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 we saw and this actually as an energy utility gathers very excited you should have seen our colleagues in the heat Department and when they found out that silicon chips produce 100 percent co2 free heat so literally a silicon chip takes power as an input one 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 they doesn't operators were very confused I can tell you that and so in order to test this we decided that we're going to build a an actual test bed and now Retta 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 but we are all a bit more about sustainability I would say and I said yes of course you can do this a bit with openshift you can start moving kubernetes continuous around and we can figure out a way how to make a flexible and we also found some other partners Clos and heat that does the heat extraction first explain how this works Helio helps us look at compute as more of a commodity and of course Nvidia could 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 now that's a pretty high number and explain to you how difficult it is and we want power consumption to be flexible so but in order to do this like I said we built to test sides 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 container eyes data centers but there are some challenges because when you talk to data center people you were here a lot they will say yeah of course we can give you the heat it's no problem we were 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's basically the inflow temperature of datacenters 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 5 Kelvin that's the Delta 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 datacenter doesn't have a flat work load line and it's not running at 100% capacity all the time if you're lucky it runs at 40% so we had 2 right now we do this with all the sec we we had to manipulate actually the workload so sometimes when we have heat demand in winter where we really need a continuous flow of six degrees Celsius we actually ramp up artificial workloads so so we recycle 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 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 open shift to actually we we are telling open shift 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 now which is a bit trickier but all of this it's it's working now but it's there's one last challenge it works for for artificial workloads so for form for HPC or simulations that just need two CPU at the moment so far when we throw a data in and we have some projects internally where we use really large data sets to forecast 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 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 for so free 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 this morning about open shift 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 it's 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 stopped 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 nan none of in the 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'd 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 oh that's it [Applause]
