    A typical question that arise with data centers is the need to cool down the overheating servers they contain. The more they will compute, the more they’ll heat, consume energy, but also will therefore be in need to be cooled down, so to stay in operation (wide range of operation would be between 10°C – 30°C). While the optimal server room temperature seem to be around 20-21°C, ~27°C for recent and professional machines (Google recommends 26.7°C).

    The exact temperature of function is subject to discussion and depends on the hardware.

    Yet, in every data center comes the question of air conditioning and air flow. In this case, it always revolves around the upper drawing (variations around this organization): 1° cold air aisles, floors or areas need to be created or maintained, where the servers will take their refreshing fluid and 2° hot air aisles, ceilings or areas need to be managed where the heated air will need to be released and extracted.

    Second drawing shows that humidity is important as well depending on heat.

     

    As hot air, inflated and lighter, naturally moves up while cold air goes down, many interesting and possibly natural air streams could be imagined around this air configuration …

     

  • OpenCloud (Academic Research) Mesh

    Note: When we had to pick an open source cloud computing platform at the start of our research, we dug for some time to pick the one that would better match with our planned activities. We chose ownCloud and explained our choice in a previous post, so as some identified limitations linked to it. Early this year came this announcement by ownCloud that it will initiate “Global Interconnected Private Clouds for Universities and Researchers” (with early participants such has the CERN, ETHZ, SWITCH, TU-Berlin, University of Florida, University of Vienna, etc.) So it looks like we’ve picked the right open platform! Especially also because they are announcing a mesh layer on top of different clouds to provide common access across globally interconnected organizations.

    This comforts us in our initial choice and the need to bridge it with the design community, especially as this new “mesh layer” is added to ownCloud, which was something missing when we started this project (from ownCloud version 7.0, this scalability became available though). It now certainly allows what we were looking for: a network of small and personal data centers. Now the question comes back to design: if personal data centers are not big undisclosed or distant facilities anymore, how could they look like? For what type of uses? If the personal applications are not “file sharing only” oriented, what could they become? For what kind of scenarios?

  • World Brain: a journey through data centers

    World Brain” by Stéphane Degoutin and Gwenola Wagon (2015)

     

    wherewelive

    World Brain proposes a stroll through motley folkloric tales : data centers, animal magnetism, the Internet as a myth, the inner lives of rats, how to gather a network of researchers in the forest, how to survive in the wild using Wikipedia, how to connect cats and stones…
    The world we live in often resembles a Borgesian story. Indeed, if one wanted to write a sequel to Borges’ Fictions, he could do it simply by putting together press articles.
    The World Brain is made out mostly of found materials : videos downloaded on Youtube, images, scientific or pseudo scientific reports, news feeds… [...] World Brain takes the viewer through a journey inside the physical places by which the Internet transits: submarine cables, data centers, satellites. The film adopts the point of view of the data. The audience view the world as if they were information, crossing the planet in an instant, copied in an infinite number of instances or, at the contrary, stored in secret places.

  • Cloud Computing design exhibit in Saint Etienne

    The Cité du Design in Saint Etienne (France) had an exhibit about cloud computing few months ago. It was part of an initiative by Orange, the French telco, that asked design students to speculate about “the personal digital space of tomorrow.” The question they addressed are the following:

    What new uses? How to organize this space for storing personal data? How to avoid being overwhelmed by all the content that we unwinttingly store in it on a daily basis? How to make the memories that we capture on video and in photos more accessible? How can we easily send all or part of this special prvate space to the people we love? Can we find a new material or emotional value for this data?

  • (The reasons why an I&IC’s) OwnCloud Core Processing Library

    Beside the reflection produced by the overall Inhabiting & Interfacing the Cloud(s) project and the related necessity to provide “access to tools” to a larger community (largely described in the founding document of the project and in a former post about the setting up of this library), new paradigms may arise in the global organization of servers farms. These new paradigms may in return generate new ways to organize files on cloud servers (by a different control of the redundancy principle for example, or a different use of file’s duplication, etc.), allowing for new projects.

    In order to answer the stakes of the I&IC design research and to prepare such output/proposals, we have developed the OwnCloud Core Processing Library that will allow to setup a software layer on top of the hardware layer.

     

    To download and learn how to use the OwnCloud Core Processing Library, we’ve prepared a post in the Cook Books section of this site.

  • Cookbook > How to set up Processing to use the OwnCloud Core Processing Library

    We will describe how to use the OwnCloud Core Processing Library within the Processing framework, starting from a blank sketch. Library’s functions will be refined and new ones may be developped, some additional libraries will be added as well in order to propose high level functions deeper linked to the IICloud(s) project.

  • I&IC Workshop #4 with ALICE at EPFL-ECAL Lab: output > Distributed Data Territories

    Note: the post I&IC Workshop #4 with ALICE at EPFL-ECAL Lab, brief: “Inhabiting the Cloud(s)” presents the objectives and brief for this workshop.

     

    The week of workshop with ALICE finished with very interesting results and we took the opportunity to “beam” the students presentation to LIFT15, where Patrick Keller and Nicolas Nova were presenting the research project at the same time. The EPFL architecture laboratory already published a post about the workshop on their blog. The final proposals of the intense week of work were centered around the question of territoriality, and how to spread and distribute cloud/fog infrastructures. You can check out the original brief here and a previous post documenting the work in progress there.

    Visibility?

    Proposing to make these infrastructures visible raised a flood of questions concerning their social and architectural status. Similarly, it questions several fields about the presence of private data in the public space. How do we represent the data center as a public utility? What types of narratives/usage scenarios emerge from such a proposition? By focusing on different but correlated territorial scales, participants were able to produce scenarios for each case.

    Swiss territoriality and scale(s)?

    The three distinct territorial scales chosen were the following: the national/regional scale, the village/town or city, and the personal/common habitat scale. The proposals were established on the basis of an analysis of the locality where the workshop was held: the small city of Renens and its proximities. The research process focused on preexisting infrastructures which responded to several criteria necessary to implement server rack structures: access to regular and alternative power sources, access to cooling sources (water and air), preexisting cabled networks and/or main and stable access routes (in the mindset that the telegraph/telephone lines were setup along the train lines), and finally seismic stability as well as a certain security from other natural disasters.

    Doing so, it also speculates about the fact that data centers could (should?) partly become public utilities.

     

    Water, water mills?

    The first proposition was to rehabilitate old water mills along existing rivers on the countryside leading to cities and villages in the role of “data sorting centers” or “data stream buffers” facilities. As there is no cabling this proposition may seem odd, however especially concerning Switzerland’s topography, the idea is interesting as it investigates several culturally rich aspects, not to mention the abundance of water. The analogy between water streams and network flows seems obvious, but water is also a necessary cooling source for data infrastructures. It could also be considered as a potential energy source. One could even go further and speculate on the potential interactions between the building and wildlife, as in the image used to cover this article published by Icon magazine just a few days ago.

    Disused post offices?

    On the scale of the city, the preexisting infrastructure chosen was the Post Office. Postal services are still functioning, but the buildings are deserted of much of their social interaction with the public since the coming of age of internet access. The buildings are also identically structured on a national scale, which could facilitate implementation. They are strategically positioned and already well equipped with network standards. Moreover, it could revive the social role of the village square, or redefine the city as a radial organization around data (versus spirituality). Amongst the implementations discussed were the ability to use the excess heat to create a micro-climate over the square and the possibility of redefining the public space inside the post office as a Hackerspace and Makers Lab, a bit in the same way libraries function.

     

    17_IMG_5461_web 18_IMG_5465_WEB

    The “front” and “back ends” of most villages’ disused post offices offer quite interesting and appropriate spatial organization, if not metaphors.

     

    Neighborhoods’ nuclear shelters (from the cold war period)?

    On the scale of the office or housing building, the nuclear shelter was immediately proposed. In Switzerland, every home is to have a nuclear bomb shelter. This situation is unique in the world, and most obviously, better serves local metal groups and wine cellar enthusiasts then security. Nevertheless, however awkward this may seem, these shelters are almost a blueprint for a personal data center. Every one of them is equipped with high-end air filtering systems, generators for use in case of power outings, and solidity and stability standards set to resist a nuclear attack. This couldn’t become a model for the other countries though…

     

    22_IMG_5514_web 23_IMG_5517_web

     

    The building would therefore embed the capacity to develop it’s own thermal ecosystem alongside the usage of private, communal and public dataspaces.

     

    26_IMG_5478_web 27_IMG_5470_web 29_IMG_5468_web

     

    This last proposition is finally interesting as it would redefine the organization of the habitat as a radial one, a bit like the students-researchers suggested earlier above for the city. The building could therefore become a transition space in itself between public space, community space and private space. Different directions were also explored with a particular interest on the vernacular “chalet” as a possible candidate for an alpine “meshed data harvesting facilities” scenario.

    For now, we’ll stick to the dream that one day, every family in Switzerland will be able to send their kids play in the data center downstairs. But remember: No Ovomaltine on the ethernet hub!

    As the week unrolls the workshop is starting to produce scenarios. Wednesday (yesterday) we had a quick presentation of the work in progress, which is documented briefly in the current post. Students Delphine Passaquay, Tanguy Dyer, Francesco Battaini & Anne-Charlotte Astrup working on Inhabiting the Cloud(s) as a team developed a global perspective on the subject. Their approach is focusing on four distinct territorial scales in order to question the centralized data center model. While the proposal doesn’t have a name yet, it however clearly speculates about a distributed isotrope network. The student architects focused on the preexisting urban infrastructure in order to establish their proposal.

    Note: we mentioned this “bookazine”, Clog, in our bibliography (Clog, (2012). Data Space, Clog online), at the very early stages of our design-research project. It is undoubtedly one of the key references for this project, mostly related to thinking, territory, space and therefore rather oriented toward the architecture field. It will certainly serve in the context of our workshop with the architects (in collaboration with ALICE) next week, but not only, as it states some important stakes related to data in general. This very good and inspiring magazine is driven by a pool of editors that are Kyle May (editor in chief, we invited him as a jury member when we –fabric | ch with Tsinghua University– organized a call during 2013 Lisbon Architecture Triennale, curtated by Beatrice Galilee), Julia van den Hout, Jacob Reidel, Archie Lee Coates, Jeff Franklin.

    The edition is unfortunately sold out. Reason why I assembled several images from the bookazine (for the research sake) in a pdf that can be downloaded here (60mb).

    SANTA CLARA, Calif. — Jeff Rothschild’s machines at Facebook had a problem he knew he had to solve immediately. They were about to melt.

     

    The company had been packing a 40-by-60-foot rental space here with racks of computer servers that were needed to store and process information from members’ accounts. The electricity pouring into the computers was overheating Ethernet sockets and other crucial components.

    Thinking fast, Mr. Rothschild, the company’s engineering chief, took some employees on an expedition to buy every fan they could find — “We cleaned out all of the Walgreens in the area,” he said — to blast cool air at the equipment and prevent the Web site from going down.

    That was in early 2006, when Facebook had a quaint 10 million or so users and the one main server site. Today, the information generated by nearly one billion people requires outsize versions of these facilities, called data centers, with rows and rows of servers spread over hundreds of thousands of square feet, and all with industrial cooling systems.

    Note: Off the Network, a book by Ulises Ali Mejias that is interesting to read when it comes to objectify and question the network paradigm. Beyond the praise about participation and inclusiveness that was widely used by network advocates and now also by marketing companies, Off the Network brings a critical voice and addresses the centralization, or in some other cases the “nodocentrism” that is at work through many global online services, so as the commodification of many aspects of our lives that comes with them.

    While we are looking for alternative “architectures” for cloud infrastructure, nodes and services, this is a “dissonant” point of view to take into account and a book that we are integrating into the I&IC bibliography.
