A good DCIM, the all-seeing eye of LCL

header-DCIM-2

LCL has relatively large data centers at 3 locations. For data centers of this scale, good management of the infrastructure is crucial for reliable, smooth and organized operation. We use sophisticated software for DCIM, developed specifically for LCL. This includes our exact floor plans and the electrical diagrams for each data room. We work together with Perf-IT for this. Their application brings all our hardware together in one DCIM system. For example, cooling systems from different brands can be seamlessly integrated into the system.

What is mainly being watched at DCIM? It is about checking all important parameters in a data center: the temperature, power consumption, capacity and efficiency. At LCL, one system controls all these factors. In this way, employees can monitor their proper functioning day and night at a glance. This central, comprehensive approach makes the information much clearer than when you have to consult different systems. In the event of a warning or problem, the application also immediately gives an indication of the cause. The seriousness of the report becomes immediately apparent, even remotely.

Regarding temperature for example, we see the values ​​in the various halls and the impact thereof for each customer at a glance. In addition, the redundancy is closely monitored. Everything must be able to work redundantly in terms of temperature, but also in terms of electricity. Capacity management is also much simpler, both for the data center in general and for the customers individually. For example, when a customer consumes 80% of his available capacity, a warning may appear.

Thanks to our DCIM system, our customers enjoy extensive and clear reporting. This way they are informed in detail about the status of their servers. Thanks to our extensive analyzes, we can also inform them well in advance of evolutions that are best addressed. A too high power consumption can, for example, cause the redundancy to be too small. In that case we contact our customers preventively and indicate what the possible solutions for this are.

A good DCIM system bears fruit not only for our customers, but also for LCL. The “Power Usage Efficiency” (PUE) is closely monitored: after all, the ratio between customer power usage and infrastructure load should be as close as possible to one. This way we avoid unnecessary costs. On the other hand, it helps us to work more efficiently and sustainably. For example, the cooling has already been fine-tuned. Our energy consumption decreased significantly by changing the temperature control in the server rooms and by adjusting the rotation speed of the fans of the air-conditioning outdoor units.The DCIM application is also linked to invoicing, which means that the consumption per customer is thoroughly documented and calculations are made automatically.


After almost 2 years, the DCIM project at LCL has almost been finalised. The project took a lot of time because it was tackled one site at a time. Moreover, many analyzes preceded: for example, every power board and every flow meter was checked. The customized user interface required a large investment, but we think it is more than worth it. In the future we will also have a mobile DCIM app, so that employees can consult all the information via their mobile phone. That is something to look forward to!

Driving down energy consumption

driving-down-energy-consumption

With a wave of climate related protests sweeping Belgium and several other European countries, it is clear that climate change has taken hold of the public’s attention. At LCL we are well aware of our position in this problem. Data centers consume a lot of energy. The ICT-sector is responsible for 2 percent of worldwide CO2-emissions, according to the United Nations. With the advent of further digitalisation and cloud computing, that figure is set to climb even higher in the future.

This gives us a responsibility to act on and save energy wherever we can.

Fortunately, at LCL, we have the right men and women for the job. Over the last few months we have been optimizing our cooling regulation and equipment to decrease our energy consumption without any impact on our customers. This has allowed us to cut energy consumption in the testing part of our data center by no less than 65 percent. Needless to say this makes a huge impact on the effect our data centers have on the environment.
How did we achieve this? Until now we have had a certain way to keep the temperature low in our data centers. As our customers’ equipment creates a lot of heat and is sensitive to high temperatures, this is crucial to our operations. As is common practice in data centers, our server rooms have a ‘cold corridor’.  At LCL, these corridors have been around for year. Where we have been innovating during the past 6 months, is in temperature management. Our engineers have been experimenting with our temperature settings.

In the past we would maintain a constant temperature inside our server rooms themselves, extracting the air as it heats up and injecting cooler air. However, maintaining a constant temperature inside the cold corridor turns out to be a more efficient way of cooling, thus saving a lot of energy. The servers pull up the air from underneath the raised floor, into the cold corridor. The temperature is allowed to rise inside the room, without any effect on our equipment inside the cold corridor. This way there is less cooling to be done, hence less energy that needs to be used.

Another breakthrough was realised by modifying the speed of the fans of the cooling system outside our building. Before these would be either off or running at full speed, with no setting in between. By making the speed of the fans variable, these do not have to work at full capacity all the time, thus saving extra energy.
By using these techniques we are implementing a key part of the ‘European Code of Conduct for Energy Efficiency in Data Centers’. We are the first endorser of this code in Belgium and believe very strongly in its goals. Implementing this new cooling solution has been a challenge, especially in a live environment. Realising this project gives a great deal of satisfaction. We will now work towards expanding our test area and implementing this solution in all of our data centers.

Data centers and the ICT-sector in general inherently use a lot of power. They are also indispensable to our modern world and economy. All that does not mean that we must not strive to cut that power consumption as much as possible. At LCL, we are showing that we are more than ready to take on that responsibility.

Your apps are like icebergs

your-apps-are-like-ice-bergs-headerIn just ten years, your smartphone has become the central technological device in your life. But do you really know how it works? See, your smartphone is like an iceberg. What you can see above the water is in fact just a tiny part of the whole structure. Every app and service requires a huge operating infrastructure that you’re probably not even aware of. Data centers like LCL play a crucial role in keeping your smartphone running.

When mobile phones broke through in the late ‘90s and early ‘00s, they had three main functions: make calls, send text messages and play snake. That has changed profoundly. Our mobile phone became smart. Now we are so used to its functionality and user-friendliness that we don’t have a clue what it takes to make the phone smart.

There’s a massive infrastructure behind the operating system and behind every app you install on your phone. The main features of a smartphone are the connectivity and the ability to exchange data that’s on your phone with data that’s stored on other locations.

One small example: adding an event to your calendar. The data of your appointment needs to be stored, obviously. But your phone also needs to communicate with other synced devices like a laptop or tablet. And this data always needs to be shared, whether you are at home or on holiday in New Zealand.

Another example is Netflix. When you watch a movie on Netflix is that you get access to files and you stream them to your device. Obviously this requires constant data traffic. Furthermore, this isn’t a one-way trip. Netflix also needs to handle the feedback you give via your account. All this data trafic requires fast and powerful connections, trustworthy operators and, of course, data centers that assure data storage and communications.

Another factor that needs to be taken into account is all the energy this requires. Sending a signal halfway around the globe requires a lot of power. All of the infrastructure that is needed to power the apps on your smartphone uses energy and resources. In this day and age, with growing concerns about climate change and emissions, this will become an issue. Just like cheap flights and car emissions, the energy consumption by our digital infrastructure will be under the spotlight. That’s why at LCL, we are committed to ‘going green’ and conducting our operations as efficiently as possible.

Will there be sufficient people to run our digital lives?

blog januari

We’re evolving towards a digital world. Erm, no. Let me start over. We live in a digital world. And things around us will only become more digital. Our smartphones are more and more becoming the center of our lives. We make phone calls, send txt messages, FB, watch movies, buy stuff, book holidays, taxi rides and hotel rooms. We manage our finances, track and share our sports activities, we navigate to any location, we leave a trail of where we were … all with one device.

Whether we realise it or not, this device that fits nicely in our hands is backed by an immense, ever-expanding network of applications, servers, connections and infrastructure. Things that need to be continuously developed and maintained. To do that, requires people. And that’s where we have a problem in Belgium. Our workforce isn’t growing fast enough and isn’t retrained fast enough. We still have people sitting in un employment. Unless we take action now and activate our workforce at an increased rate, we won’t be able to keep up with the digital pace. I guess however, Belgium’s not the only country struggling to fill all job openings.

According to Agoria (the umbrella organisation of all Belgian technology-based companies), more jobs are appearing than disappearing (+0,9% per year) while the workforce is growing only slowly (+0,3% per year). On top of this, digitalisation is changing the content of every job; for some limited, for others quite radical. Unless we take action, digitalisation and economic dynamics will result in more than half a million unfilled posts by 2030, in Belgium alone.

Expert jobs require expert people. Keep people within their focus, they’ll perform better and will be more engaged. People sometimes assume that data center housing is an IT job. It’s not, it’s an engineer’s. Data center construction and maintenance require expert knowledge on electrical power and circuitry, engines/generators, cooling and heating, architecture, security, energy efficiency… So why would you want to train an IT person to do an engineer’s job? It’s a completely different skill set. Anyway, you could use that IT person to focus on IT projects. That’s what you hired her/him for in the first place.

And why would you want to do it yourself inhouse. Besides the skill set, a data center that has an uptime of over 99,9%, requires a state-of-the-art infrastructure which by itself is a huge investment. We already made that investment, so why not outsource yours and benefit from the economies of scale? That way, you can also save on office space, which you will need for your future staff.

Be The Change – Shaping the Future of Work is a campaign by Agoria. Would you like to find out how our workforce – and you – will be impacted by the digitalisation of our lives; will you be the change? Then visit the Be The Change landing page.

Your privacy in times of data breaches

 

In this blog I want to discuss a remarkable video that I recently watched on LinkedIn (‘Amazing mind reader reveals his ‘gift’’). It’s a video from Febelfin, the Belgian federation of the financial sector, to promote safe internet banking. We see a mind reader who traces back all sorts of personal information of random people just by reading their minds: tattoos, the colour of their house, medical information, details of their love life… He even ‘reads’ their bank account number and how much they spent on clothes over the last month! Of course all these people are genuinely surprised. At the end of the video one discovers how exactly he knew these personal details about the participants… I suggest you go and discover it yourself first.

I thought this video was quite shocking. You as well? Without knowing it, people are throwing away all kinds of private information about themselves online. Hackers can uncover your private life and can even trace your bank account number. Most people however do not seem to lose sleep over what happens with their online data. We share details about our life without thinking about the consequences, or where all this data is stored or what it is used for. People are kind of naive when it comes to online privacy. A few multinationals, like Facebook and Google, are using our online traces for their own good. In addition, news about data breaches is everywhere. The most recent incidents reported are from Dell and Marriott, in the latter case over 0.5 billion people are impacted. Their private information has gone public. The list of data breaches is endless.

Jaak Geens, founder of the NPO Geens.com, and his team developed a platform to let users take back control (individuals, governments or businesses) over their data. The purpose of this platform is to secure privacy and personal data online. The technology is based on encryption and blockchain, making your personal data private and allowing you to share it only with the ones you want to share it with. It’s basically a vault. Because you know, the cloud (where all our social media information for example is going to), is not a synonym for private. Geens not only covers the individual. Privacy by design is their credo for businesses. When organisations develop new software, it’s good to already keep the privacy aspect in mind from the initial development.

The analogy between this ‘geens’-vault for your data and our data centers as a vault for your servers is an obvious one. In times of cybercrime and data breaches, not only your data should be stored safely, your servers containing the data should be placed somewhere safe and secured as well. While our world is becoming more and more digital, more and more data will be shared and transferred, digital infrastructures will only expand. Yours too. Think through thoroughly where you want to place your digital infrastructure and processes. You do want to keep full control, don’t you?

So it’s good to be thoughtful about your data and to keep everything under your own control. Losing data or the connection to it, imposes a high financial and competitive risk. Data protection in these times of data breaches is the best investment you can make.

Data center vs. Cloud – The best of both worlds

Gartner, world’s leading research and advisory company, predicts that 80% of enterprises will have shut down their traditional on-premise data center by 2025. Companies’ IT requirements are evolving, because business and customer needs are changing. New technologies like the Internet of Things or edge services are pushing companies away from their data center. Furthermore, businesses are developing IT strategies that focus on their application portfolio, rather than on their physical infrastructure. Also, the customer experience is getting more attention. All this makes organizations reconsider where their applications and equipment should be housed, based on network latency, customer population clusters and geopolitical limitations.

You will probably think that this prediction is music to our ears. Partly it is of course, because when enterprises close down their own data center, they usually choose one of two options: migrating their data into the cloud or moving their servers to a professional data center. However, these days there is a ‘cloud first’-hype. Some companies decide to go with one of the large cloud players like Microsoft, Amazon, Google or Oracle. But at LCL, you can get the best of both worlds as we provide easy access to multiple cloud providers. Our cloud neutrality allows you to connect directly to one of our partners. By which we mean Belgian cloud providers who house their clouds at our data centers like for example Arcadiz, Arxus (Cronos Group), Cheops, Combell, Fujitsu, Nucleus, Proact, RealDolmen, Savaco or Sentia.

Another option is of course to skip the cloud and to store your data directly at the servers in a professional data center. Your own data center requires a lot of maintenance, but this service is included at external data centers like LCL. Our trained staff has the right skills and knowledge to take care of all our critical infrastructure 24/7, making sure your equipment keeps running without interruption. Power cuts, lightning strikes, fires, insufficient cooling, security breaches, … these are the things you don’t need to worry about. We take care of that, while you can focus on your core business. And let’s not forget the other services which are included at LCL: redundancy and security. Also, our carrier neutrality gives you the flexibility to easily switch between different operators.

IT infrastructure is getting more complex every day, so companies are looking for external service partners to help. Maybe you are as well? We offer you business continuity, crucial in today’s business world. And on top of that you can replicate all your critical data to one of our other data centers. If I were you, I would rethink my IT strategy sometime soon…

Data centers trying to beat the heat

After six weeks of sunshine and high temperatures, I reflected on how well the cooling installations in our data centers were performing and the fact that so far we hadn’t encountered any problem this summer. The very next day, however, one of our air conditioning units indicated it suffered badly under the extreme conditions of the persisting heat. Fortunately, we designed our systems to be fully redundant, and our team, which was on the scene immediately, kept their cool and did an excellent job in resolving the incident.

In the past, things were different. When we first opened our data center, over 15 years ago, we faced problems as soon as the weather turned hot. This was often the result of inadequate maintenance, such as when the cooling generators on the roof became clogged up with pollen. Since that incident, we have carried out additional maintenance work every spring to remove the pollen. On very hot days we had to contend with failing systems, and this was particularly problematic when a second site was affected too. While this was very frustrating, it taught us that we needed to address the issue of cooling differently.

Practice makes perfect, so when we made new investments we took into account the fact that roofs become particularly hot in the summer, for example – thus generating more heat inside of the data centers. Our new data centers were therefore designed with extra large cooling generators on their roofs to ensure they can deal with high temperatures.

Given the heatwave currently hitting our country – the second already this summer –, we are very glad that we took those decisions. We will have to take even higher temperatures into consideration if global warming continues. If climate change creates additional problems in the future, the design of data centers will have to be fully adapted to cope with that phenomenon.

In Uptime Institute’s annual global data center survey (2018) of almost 900 data center operators and IT practitioners, 46% of respondents said that their organizations were not addressing potential climate change disruption to their data centers. The advice is to conduct disaster and emergency planning in the context of a broader emergency and business continuity plan. At LCL, we take the Tier design criteria into account in order to increase operational efficiency and improve the reliability of our business critical infrastructure. We also test our backup systems once a month by simulating a power outage. Floods may not occur often in Belgium, but (heat) thunderstorms do take place once in a while… We at LCL, are prepared for the rapidly changing climate conditions.
