Jaguar Network launches the construction of a 3ᵉ DC in Lyon

After acquiring DCforData and its datacenter in Limonest in 2018, Jaguar Network inaugurated its second datacenter called "Rock" a year later in the 8ᵉ district of Lyon. The operator and host, a B2B subsidiary of the Iliad Group, is today launching the construction of a third site.

 

This new facility will meet the exponential demand for data hosting in the Auvergne-Rhône-Alpes region, and thus preserve this sovereignty in the immediate vicinity. The aim is to immediately offer new, complementary services for pioneering sectors such as Industry 4.0 and e-Health.

 

The hosting architectures now spread over three active sites will make it possible to address requests from all over the Lyon metropolitan area and its region, while guaranteeing the diversification and security of the power supply.

Interconnected with leading international operators as well as national and regional operators, this new very high-speed communication node will support new uses and the city's transformation by optimizing connectivity.

Specializing in smartcity and the challenges of AI and big data, this new datacenter will be designed to create new partnerships with the ecosystem and open up new opportunities for a rapidly changing employment pool.

 

An announcement confirming the Iliad Group's investment in fiber optics as it aims to connect 100% of the companies in the AuRA region by 2024.

For Jaguar Network, this is the affirmation of its installation in France's second-largest economic region in connection with its historical market of SMEs, ETIs and large accounts. This prefigures the forthcoming arrival of the Iliad Group in the corporate market.

Digital Transition: Developing Local DCs

on Thursday, 07 May 2020 Posted in Archives Rezopole

Digital Transition: Developing Local DCs

The Urban School of Lyon continues its conferences entitled "The Wednesdays of the Anthropocene". This week's theme: the impact of digital technology on regional planning with Cécile Diguet, urban planner, director of the Urban Planning and Territories Department of the Paris Region Institute and Jean-Vincent Bayarri, architect of Information Systems at the Metropolis of Lyon.

As a partner, Rue89Lyon publishes a podcast of these forums. Jean-Vincent Bayarri, also wrote the text below.

 

The intelligent city relies on important digital infrastructures, especially data centers. How are these infrastructures deployed on the territory? What issues are raised by their spatial integration? Constraints or opportunities for an ecological factory of the city? Are digital actors the new protagonists of the urban project?

 

Initially, containment...

Videoconferencing, streaming, telecommuting, e-commerce, online gaming are in this period of confinement even more widely consumed than usual by the French.

Many articles in the press explain how consumption induced on "networks" alone can be problematic, at the risk of "slowing down" or even "paralysing" the Internet.

 

"The networks"

Above all, the Internet is a set of interconnected machines, i.e. multiple routes, managed by a multitude of actors: operators, public or private structures, associations, large companies. The term "network" is actually vague since it is a multitude of interconnected networks. At the end of the chain is a server infrastructure that must meet the high demand observed in this period of containment.

 

While it is true that some networks can sometimes be scarce resources, particularly mobile networks, most are well sized in France to carry the traffic.

So when the website of a hypermarket brand, overwhelmed by the requests of confined consumers, displays a message asking to wait, is it the fault of the "network"? Certainly not.

The problem can often come from the last link in the chain, the "server" carrying the resource and the content consumed. How do you know when and where to align sufficient resources to meet demand?

 

Datacenters

This is the importance of data centers, since they allow multiple servers to be quickly assigned to specific tasks.

And this capability also applies to the datacenters themselves! Just as the Internet is meshed and decentralized, the strategy adopted by companies like Netflix is a very wide distribution of data centers: on several continents, in several cities, and even as close as possible to the user, partly at the ISPs themselves. It is also a common practice in most companies to distribute resources across multiple data centers for reasons of security, redundancy and high availability.

 

Proximity, a technical, economic and strategic asset

Some cities have a considerable asset: a GIX (Global Internet eXchange point), i.e. a local Internet exchange point. In Lyon, this is LyonIX, which is managed by Rezopole. Companies or administrations that wish to do so can connect locally to this GIX and exchange via the Internet "locally".

Thus in the Lyon metropolitan area, a very significant part of Internet traffic is consumed by Google services (Maps in particular). Since Google is present on LyonIX, access is not only instantaneous (very low latency) but also free of charge. The rest of the Internet traffic is sold through the (paying) pipes of a forwarding agent.

 

Beyond purely telecom costs, the logic of economic development is clear: the more Internet infrastructure is present locally, the more investors are attracted to build local datacenters. This rhymes with more jobs, more value created, and an easier digital transition.

The interest is also strategic, since putting your data in the "cloud" means putting it in someone else's datacenters. A varied and local offer of datacenters therefore makes it possible to keep company data on national soil, in better security conditions (RGPD for example), which represents a certain digital sovereignty.

 

Digital transition, ecological?

"To save the planet, print this message only if necessary". This maxim could almost sum up the digital transition issue by itself.

Videoconferencing, the development of mobile digital counter applications, these are just a few examples of very concrete applications - made possible by the presence of these infrastructures, these networks, these data centres in the city - which also facilitate the ecological transition.The data centres themselves are working on this with the reduction of the energy efficiency factor or the reuse of heat produced by the district heating of the surrounding area, or even a 100% operation on renewable energies.

 

The digital revolution has given data centers a now multiple importance (economic, social, ecological) in the city as well as other essential structures. A central link in regional planning and the digital and ecological transitions, which are far from being in opposition, are perfectly complementary.

Heat wave: why French DCs are holding up

on Thursday, 01 August 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Heat wave: why French DCs are holding up

Heat episodes are not taken lightly by data center operators. In France, "we have gone from 40 degrees to 46 degrees in a few years. We have met the specifications of Spain," says Marie Chabanon, Technical Director of DATA4 Group.

 

In order to counter any heat stroke, the datacenters' resistance to temperatures has increased " The great fear is the domino effect [...] If all or part of the cold infrastructure has problems, it affects the rest of the equipment. And if the refrigeration unit stops, it's the worst thing that can happen to us with the complete power outage," added Fabrice Coquio, Interxion's Managing Director. A risk also linked to the quality of RTE or Enedis' electricity distribution. "We must anticipate a risk of electrical loss or incident," explains Marie Chabanon.

 

But data center operators have a secret boot to fight this domino effect. "Data center electrical systems are built to be 100% operational. However, this is never the case. The consequence is that in the event of a load, such as a higher cold demand, we have unallocated power that we can use," explains Fabien Gautier of Equinix. This is called capacity redundancy.

 

Especially since the densification of computing power per unit of space in recent years, with the democratization of virtualization, has led to more consumption and more heat. "With 14 or 15 kvA berries, we cause hot spots, which are more sensitive to heat waves," explains Fabien Gautier. The work of urbanizing the IT architecture deployed in the rooms is therefore essential. "Our work is therefore the urbanization of the rooms. If they were completed on the fly, that can be a problem," he adds.

This involves, among other things, load balancing. "Our data centers are designated with redundancies and a 50% load rate. The backup machines will be used to provide additional power" in the event of a heat wave, says Marie Chabanon. Nevertheless, it must be anticipated. "We must ensure that backup systems are ready to be operational, through maintenance and control actions on backup equipment."

 

The protection of data centers against heat also requires the installation of curative systems. "We installed water spray systems to water the roof equipment with water that is not too cold," says Fabrice Coquio.

And to be prepared for any eventuality in the early evening, the schedule of the technicians present on site has been modified. It is also necessary to warn customers so that they are careful.

 

Recent advances in hardware strength and data center design have made it possible to increase the temperatures in server storage rooms. "The idea is that the lower the PUE (Power Usage Effectiveness), the better it performs. Ten years ago, we used to make datacenters where it was difficult to achieve a PUE of 1.6. Today we are at 1.2 and we are getting closer to 1, which represents 20% savings by playing on the temperature and energy performance of the new equipment," says Marie Chabanon. As a result, the cooling system now focuses on machines with forced air. There is no longer any need to refrigerate entire rooms.

"We are seeing an evolution in the design of indoor temperature according to the recommendations of the Ashrae (American Society of Heating and Ventilating Engineers). The idea is to work well with much higher temperature ranges. We have gone from 20 to 22 degrees to 18 to 27 degrees," she adds. Since 2011, these standards have been raised: they recommend blowing at 26 degrees on the front panel on indoor equipment. "The humidity level was also modified [...] In 2008, it was between 40 and 60%. It is now 70%," says Fabrice Coquio.

 

This will limit cooling costs without affecting the resistance of the installations. A critical point in hot weather.

DC faiilures : caused by the network ?

DC faiilures : caused by the network ?

While power outages are a frequent cause of data center outages, they are no longer the only ones. Indeed, IT system failures and network errors are causing more and more failures. That's why the Uptime Institute looked at known outages to find out what caused unplanned service interruptions. To do this, the company has analyzed 162 service interruptions reported in traditional and social media over the past three years.

27 outages were reported in the media in 2016, 57 in 2017 and 78 in 2018. "Service outages are increasingly making headlines in the media," said Andy Lawrence, the Institute's Executive Director of Research. This does not necessarily mean that the number of failures is skyrocketing, but rather that downtime is attracting more and more attention. "It is clear that for users, the impact of outages is certainly more damaging today," he adds.

The study revealed that in global outages, network and IT system problems are more often blamed than those related to power supply. This is explained by the fact that power supply systems are more reliable than in the past and that there are fewer power outages in data centers.

At the same time, the increasing complexity of IT environments is causing a growing number of IT and network problems. "Data is now dispersed in multiple locations, with critical dependencies on the network, on how applications are architected and on how databases replicate each other. It is a very complex system, and it now takes fewer events to disrupt its operation," said Todd Trader, Vice President of Optimization and IT Strategy at the Uptime Institute.

This trend is all the more pronounced when comparing causes from one year to the next. 28% of outages were due to power supply problems in 2017 compared to 11% the following year. IT system failures remained relatively constant: 32% in 2017 and 35% in 2018. Outages due to network problems have increased significantly, from 19% in 2017 to 32% in 2018. "Things are linked not to one or two sites but to three or four or more sites, or even more, The network plays an increasingly important role in computer resilience," says Todd Traver.

In order to be able to distinguish an interruption that can threaten the activity of a company from a just disturbing failure, the Uptime Institute has developed an evaluation grid with a scale of 5 levels:

  • Level 1: refers to a negligible stop. The failure is recordable but there is little or no obvious impact on services and no service interruption.
  • Level 2: refers to a minimal interruption of service. Services are disrupted, but the effect on users, customers or reputation is minimal.
  • Level 3: refers to a service interruption that is significant to the company. These are interruptions in customer or user service, most often of limited scope, duration or impact. The financial impact is minimal or non-existent but there is some impact on reputation or compliance.
  • Level 4: concerns a serious operational or service failure leading to service disruption and/or operations involving financial loss, non-compliance, reputation damage and possibly even security issues with possible loss of customers.
  • Level 5: Describes a critical failure for the company or mission, resulting in a major and damaging interruption of services and/or operations, involving significant financial loss, security issues, non-compliance, customer losses and reputation damage.

 

This analysis was further developed by researchers who specifically identified the origin of data center failures.

The most common reasons for failures when the network is down:

  • fiber cuts outside the datacenter and insufficient number of routing alternatives
  • intermittent failure of the main switches and absence of secondary routers
  • major switch failure without backup
  • incorrect traffic configuration during maintenance
  • incorrect configuration of routers and networks defined by softwar
  • failure to power individual unsaved components such as switches and routers


For IT, the most common causes are:

  • poorly managed upgrade
  • failure and subsequent data corruption of a large number of disks or SAN storage systems
  • synchronization failure or programming errors in the load balancing or traffic management system
  • poorly programmed failure / synchronization or disaster recovery system
  • power loss to unsaved individual components


When the power supply fails, the reasons for the failures are:

  • lightning causes overvoltages and power outages
  • intermittent failures with transfer switches and inability to start generators or transfer to a second datacenter
  • inverter failures and lack of transfer to secondary systems
  • the supplier is unable to deliver the necessary power with subsequent failure of the generator or inverter
  • damage to computer equipment caused by overvoltages

 

"In general, companies should pay more attention to the resilience of data centers. They need to know their architectures, to understand all the interdependencies, to identify the reasons for failures, to plan solutions in case of failure. However, this last aspect is often neglected," adds Todd Traver.

Designing DCs for tomorrow today

on Wednesday, 27 February 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Designing DCs for tomorrow today

How can we succeed in building IT infrastructures in a sustainable and perennial way for the next 20 years? What are the important elements to consider during the design phase?

Although it may seem easy to build data centers, it is a rapidly evolving industry. Indeed, today's rooms are becoming denser, servers consume more and more energy and are heavier. Modularity concepts are shaking up the market every month, the ranges are evolving rapidly to better meet users' needs....

This is why adaptability and modularity must be part of the solutions to these problems from the design phases. For example, choose modular cooling and electrical solutions, increase power and load during maintenance, design large equipment by oversizing it.
It can also be very useful to implement new Agile working methods. It is therefore essential to be flexible and adapt to these changes that can affect the project in a sustainable way.
Modularity is also an essential point during the design phase, especially if you choose an atypical location to set up your data center. However, legal or regulatory aspects may run counter to this modularity. It is therefore necessary to address these problems as soon as possible, as they often have incompressible deadlines...

Development of French DCs

on Wednesday, 20 February 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

Development of French DCs

Interviewed by LeMagIT, Olivier Micheli notes that French data centers are finally attracting international cloud players and that they are expanding geographically in order to reduce latency.

Olivier Micheli, who is both CEO of Data4 Group and President of the France Datacenter Association, estimates that there are 200 large datacenters in France covering up to 10,000 m². The capital with the largest number of people because Paris is a European interconnection node.
There are between 3000 and 5000 private computer rooms of varying size and power across the country.
Beyond the desire of companies to control their equipment, the importance of ever lower latency is increasingly important in local economic activities and the development of smart cities.
According to Olivier Micheli, the market is moving towards data centres whose size is proportional to the size of the economic activity nearby.

After a slow period between 2012 and 2015, the French data center market has caught up. France is now in fourth place in Europe, tied with Ireland. There are several reasons for this: the opportunity for international companies to reach 67 million people from locally hosted IT resources, the geostrategic importance of Marseille and also the government's efforts to create favourable conditions for the development of these datacenters.
This finally allows France to align itself with the United Kingdom, Germany and the Netherlands.

The customers of these data centers are 70% of public cloud players such as Amazon, AWS but also publishers such as Salesforce. User companies want a lot of support.

The first issue for datacenters is, according to Olivier Micheli, connectivity. Indeed, companies now want to benefit from an offshore computer room in order to redistribute this data to users and Internet actors.
The second challenge is that of intelligent buildings and to achieve 100% renewable energy by using, for example, Free Cooling.

The largest datacenter in Lyon

on Thursday, 24 January 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

The largest datacenter in Lyon

Inaugurated on January 15 by the national operator Jaguar Network, the last datacenter of the Lyon metropolitan area was built within the Biopark of the 8th arrondissement. Known as "Rock", this datacenter is also the largest in Lyon with more than 4,000 m² and 800 computer bays.
This project, supported by the Auvergne-Rhône-Alpes region, now hosts IT projects in the health and industry 4.0 sectors after only twelve months of construction.

However, the building has a particular feature for a datacenter: "The aesthetics of the building has been a constraint imposed by the French building architects: Rock is located within the perimeter of the Édouard Herriot Hospital, built a century ago by the architect Tony Garnier and listed as a historic monument. Thus, to comply with the specifications imposed by the French administration, it was mandatory to equip the building with windows, walled by breeze blocks since they were totally useless for computer rooms...!" notes Pierre Col in an article in ZDNet.

The operation of the infrastructures of this new datacenter has been maximized by using, for example, artificial intelligence. "An application developed by Jaguar Network teams proactively manages the installations in order to perform preventive maintenance to maximize availability. This is how technologies based on Big Data and Machine Learning are integrated into the spectrum boxes whose mission is to predictively detect any incident," says Jaguar Network.
In addition, a team is permanently present on the site "This guarantees local support to customers for the simplified operation of their IT equipment. A technician can work on any server hosted in the heart of the building in less than 10 minutes," explains the operator and cloud host.

To demonstrate its commitment to investing in digital transformation, the company has also created a network of more than 80 km of dark fibre network. This allows any company in Lyon's metropolitan area to be connected directly by dedicated and secure cables. "A dedicated 100 Gbps network will be available from February 2019 to provide the highest connection speeds available in France for businesses," says Jaguar Network.

How does Internet work ?

How does Internet work ?

[French article]

 

Contrairement à ce que beaucoup imaginent, Internet ne flotte pas dans l‘air. Il existe grâce à des câbles, datacenters et IXP contrôlés par des entreprises. Francesca Musiani, chargée de recherches au CNRS, explique pourquoi il est nécessaire de comprendre ces rouages afin d’être un internaute avisé.

 

La spécialiste des architectures de l’Internet nous présente dans une vidéo diffusée par Treize Minutes les dessous d’un monde encore trop méconnu. Les infrastructures réseaux font en sorte que leur fonctionnement reste discret, si bien que l’on ne prend conscience de leur existence qu’au moment où Internet atteint ses limites, qui sont bel et bien matérielles. Pourtant, il est primordial de mieux conceptualiser cet outil du quotidien, qui est bien plus tentaculaire qu’il n’y paraît.

 

 

Voir la vidéo

 

 

En effet, elle soulève le fait que les diverses infrastructures Internet sont sous le contrôle d’entreprises qui poursuivent leur intérêt propre. Un fait qu’il faut bien comprendre, notamment en cette période où la protection des données personnelles et la manipulation de l’information sont au cœur de tous les débats.

 

Dans un article de Libération rédigé par Amaelle Guiton, Francesca aborde le sujet du projet de loi sur la lutte contre les « fake news ». Pour elle, l’essentiel du problème ne réside pas dans l’émetteur de ces fausses informations, mais dans le fonctionnement-même des grandes plateformes sur lesquelles elles sont diffusées.

 

Leur modèle économique leur permet de propager des informations plus rapidement que tous les autres supports, qu’elles soient réelles ou infondées. Ainsi, une solution serait de rendre plus transparente l’activité de ces émetteurs de contenu. Par l’intervention d’entités tierces ciblant l’origine systémique du problème, Francesca espère pouvoir le résoudre sans bouleverser tout le fonctionnement des grandes plateformes. De plus, elle estime que le monopole de l’information en ligne par certaines entreprises est aussi une des sources du problème, qui pourrait être palliée par l’émergence de nouveaux acteurs. Des pistes de solutions intéressantes à découvrir dans cet article.
