This also includes electrical switching; uninterruptable power supplies; backup generators; ventilation and data center cooling systems, such as in-row cooling configurations and computer room air conditioners; and adequate provisioning for network carrier (telco) connectivity. It also facilitates performing routine maintenance on either physical or virtual systems all while minimizing interruption. Niles, Susan. All of the actions network, storage and server virtualization accomplish can be implemented through software, giving traction to the term software-defined data center. Colocation -- The organization pays a vendor to house their hardware in a facility. Great piece! Old large computer rooms that housed machines like the U.S. Army's ENIAC, which were developed pre-1960 (1945), were now referred to as "data centers". Tier 1 is the simplest infrastructure, while Tier 4 is the most complex and has the most redundant components. It comprises components that include switches, storage systems, servers, routers, and security devices. [42][43], The first purpose of the raised floor was to allow access for wiring. Small businesses may operate successfully with several servers and storage arrays networked within a convenient closet or small room, while major computing organizations, such as Facebook, Amazon or Google, may fill an enormous warehouse space with data center equipment and infrastructure. Getting started with Windows containers requires an understanding of basic concepts and how to work with Docker Engine. Learn more. Today, the green data center , which is designed for minimum environmental impact through the use of low-emission building materials, catalytic converters and alternative energy technologies, is growing in popularity. A Cloud Data Center is just like a traditional data center except that the cloud services provider is an expert vendor who is providing all the needed services and support. These standards will protect most companies. Multiple log entries can occur at the main entrance, entrances to internal rooms, and at equipment cabinets. Terminologie data center. Datacenter definition, a facility equipped with or connected to one or more computers, used for processing or transmitting data. Communications in data centers today are most often based on networks running the IP protocol suite. Alternatively, a range of underfloor panels can create efficient cold air pathways directed to the raised floor vented tiles. It became possible to store all of a company's necessary servers in a room within the company. Data center services encompass all of the services and facility-related components or activities that support the implementation, maintenance, operation, and enhancement of a data center, which is an environment that provides processing, storage, networking, management and the distribution of data within an enterprise. Telcordia GR-3160, NEBS Requirements for Telecommunications Data Center Equipment and Spaces,[20] provides guidelines for data center spaces within telecommunications networks, and environmental requirements for the equipment intended for installation in those spaces. European Union also has a similar initiative: EU Code of Conduct for Data Centres. A data center (American English)[1] or data centre (British English)[2][note 1] is a building, dedicated space within a building, or a group of buildings[3] used to house computer systems and associated components, such as telecommunications and storage systems. The growth of virtualization has added another important dimension to data center infrastructure management. On the other end of the spectrum is a tier 4 data center. Metrics such as PUE are no longer central to energy efficiency goals, but organizations may still gauge PUE and employ comprehensive power and cooling analyses to better understand and manage energy efficiency. Everyone should be on the same page when discussing data center modernization or any other IT/data center initiative under consideration. Renewable electricity sources are another plus. By not buying commercial off-the-shelf servers, energy consumption due to unnecessary expansion slots on the motherboard and unneeded components, such as a graphics card, was also saved. Il peut être représenté comme une usine hébergeant un énorme disque dur. For example, critical servers might be placed in a cool zone that is serviced by redundant AC units. [64], Another alternative is fitting cabinets with vertical exhaust ducts (chimney)[65] Hot exhaust exits can direct the air into a plenum above a drop ceiling and back to the cooling units or to outside vents. Le data center (centre de traitement des données en français) est l’un des éléments nécessaires au traitement et stockage des données numériques. Data centers use a lot of power, consumed by two main usages: the power required to run the actual equipment and then the power required to cool the equipment. [57] Components of the data center can be prefabricated and standardized which facilitates moving if needed.[58]. [73] Global data centers used roughly 416 TWh in 2016, nearly 40% more than the entire United Kingdom; USA DC consumption was 90 billion kWh. No water - some of the benefits of using chemical suppression (clean agent. The topology proposed in this document is intended to be applicable to any size data center.[19]. This product overview outlines the HP FlexFabric 12500 series, Learn more about the Juniper EX9200 data center-class switches. [81] The Energy Efficiency Improvement Act of 2015 (United States) requires federal facilities — including data centers — to operate more efficiently. Also a term used to describe ERP (Enterprise Resource Planning) systems for data centers. Platforms such as Microsoft Azure emphasize the hybrid use of local data centers with Azure or other public cloud resources. [72] Greenpeace estimated worldwide data center power consumption for 2012 as about 382 billion kWh. Learn more. Likewise called mechanized focus. A data center provider called Switch defined its own Tier 5 level in 2017. Dynamic infrastructure[105] provides the ability to intelligently, automatically and securely move workloads within a data center[106] anytime, anywhere, for migrations, provisioning,[107] to enhance performance, or building co-location facilities. Virtual Data Center Definition & Meaning Data centers are physical or virtual infrastructure used by enterprises to house computer, server and networking systems and components for the company's information technology (IT) needs, which typically involve storing, processing and serving large amounts of mission-critical data to clients in a client/server architecture . Data center outsourcing (DCO) is a multiyear, annuity contract or relationship involving the day-to-day management responsibility for operating server or host platforms, including distributed servers and storage. First, a definition. Air flow management addresses the need to improve data center computer cooling efficiency by preventing the recirculation of hot air exhausted from IT equipment and reducing bypass airflow. [79] Google publishes quarterly efficiency from data centers in operation.[80]. Raised floor cabling, for security reasons and to avoid the addition of cooling systems above the racks. Static transfer switches are sometimes used to ensure instantaneous switchover from one supply to the other in the event of a power failure. These early machines were complex to maintain and operate and had a slew of cables connecting all the necessary components. "In year four, our cost per kilowatt a month is about a third of what it would have been." "HP Shows Companies How to Integrate Energy Management and Carbon Reduction," TriplePundit, April 5, 2011". [88] Cooling it at or below 70 °F (21 °C) wastes money and energy. Data center designs must also implement sound safety and security practices. A data center stores and shares applications and data. The advent of Unix from the early 1970s led to the subsequent proliferation of freely available Linux-compatible PC operating-systems during the 1990s. Temperature[note 10] and humidity are controlled via: Backup power consists of one or more uninterruptible power supplies, battery banks, and/or diesel / gas turbine generators.[61]. Different liquid technologies are categorized in 3 main groups, Indirect liquid cooling (water cooled racks), Direct liquid cooling (direct-to-chip cooling) and Total liquid cooling (complete immersion in liquid, see Server immersion cooling). "Impact of Virtualization on Data Center Physical Infrastructure," The Green grid, 2010", "HP Thermal Zone Mapping plots data center hot spots", "Fjord-cooled DC in Norway claims to be greenest", Canada Called Prime Real Estate for Massive Data Computers - Globe & Mail. A simple data center may need only a few kilowatts of energy, but an enterprise-scale data center installation can demand tens of megawatts or more. Swiss Carbon-Neutral Servers Hit the Cloud. A data center is a physical facility that enterprises use to house their business-critical applications and information. [12], Modernization and data center transformation enhances performance and energy efficiency.[13]. Beyond the basic issues of cost and taxes, sites are selected based on a multitude of criteria, such as geographic location, seismic and meteorological stability, access to roads and airports, availability of energy and telecommunications and even the prevailing political environment. A data center is a facility that centralizes an organization’s shared IT operations and equipment for the purposes of storing, processing, and disseminating data and applications. Software including data center infrastructure management tools allow remote IT administrators to oversee the facility and equipment, measure performance, detect failures and implement a wide array of corrective actions without ever physically entering the data center room. The Telecommunications Industry Association's TIA-942 standard for data centers, published in 2005 and updated four times since, defined four infrastructure levels.[47]. [74], In 2007 the entire information and communication technologies or ICT sector was estimated to be responsible for roughly 2% of global carbon emissions with data centers accounting for 14% of the ICT footprint. Securing: Protection of virtual systems is integrated with existing security of physical infrastructures. There are a couple ways to connect the disparate pieces of a multi-cloud architecture. [21] The typical projects within a data center transformation initiative include standardization/consolidation, virtualization, automation and security. It is the most advanced type of data center tier, where redundancy is applied across the entire data center computing and non-computing infrastructure. Un datacenter ou un centre de données sont des serveurs informatiques pour la mise en ligne du site internet ou pour le stockage des données informatiques. Data centers are not a single thing, but rather, a conglomeration of elements. Access control at cabinets can be integrated with intelligent power distribution units, so that locks are networked through the same appliance. [39], Although the first raised floor computer room was made by IBM in 1956,[40] and they've "been around since the 1960s",[41] it was the 1970s that made it more common for computer centers to thereby allow cool air to circulate more efficiently. Data centers are increasingly implementing private cloud software, which builds on virtualization to add a level of automation, user self-service and billing/chargeback to data center administration. distributor/service company, Eight vendors' temperature recommendations can be found, instead of chillers/air conditioners, resulting in energy savings, (In this arena, only six companies were noted by Thomas, a financial data publisher), Clark, Jeffrey. Data centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center. Découvrez tout ce que vous devez savoir sur les DCIM : définition, fonctionnalités et meilleures solutions disponibles sur le marché. "Method for Dynamic Information Technology Infrastructure Provisioning", "Computation on Demand: The Promise of Dynamic Provisioning", "Just What the Heck Is Composable Infrastructure, Anyway? Sur le papier, l'idée est séduisante. Ce terme s'utilise dans le cas de l'hébergement d'un site web, car c'est généralement l'endroit où sont placées les serveurs. California's title 24 (2014) of the California Code of Regulations mandates that every newly constructed data center must have some form of airflow containment in place to optimize energy efficiency. Chaque niveau inclut les composants requis à tous les niveaux inférieurs. There is no requirement for a single data center, and modern businesses may use two or more data center installations across multiple locations for greater resilience and better application performance, which lowers latency by locating workloads closer to users. [11] Data centers typically cost a lot to build and to maintain. During the boom of the microcomputer industry, and especially during the 1980s, users started to deploy computers everywhere, in many cases with little or no care about operating requirements. Managed services -- The organization pays a vendor to. Privacy Policy A single mainframe required a great deal of power and had to be cooled to avoid overheating. Either the cold aisle or the hot aisle can be contained. A data center is the department in an enterprise that houses and maintains back-end IT systems and data stores — its mainframes, servers and databases. To qualify for the ecolabel, a data center must be within the top quartile of energy efficiency of all reported facilities. Data centers feature fire protection systems, including passive and Active Design elements, as well as implementation of fire prevention programs in operations. Because many providers today offer managed services along with their colocation facilities, the definition of managed services becomes blurry, as all vendors market the term in a slightly different way. Rows of cabinets are paired to face each other so that cool air can reach equipment air intakes and warm air can be returned to the chillers without mixing. "Standardization and Modularity in Data Center Physical Infrastructure," 2011, Schneider Electric, page 4. The U.S. Environmental Protection Agency has an Energy Star rating for standalone or large data centers. Conversely, a business with multiple data centers may opt to consolidate data centers, reducing the number of locations in order to minimize the costs of IT operations. Le « data center » (centre de données) de Facebook, installé à la sortie de la ville, est peint en couleurs neutres et ne porte aucune enseigne. Local building codes may govern the minimum ceiling heights and other parameters. In 2005, the American National Standards Institute (ANSI) and the Telecommunications Industry Association (TIA) published standard ANSI/TIA-942, "Telecommunications Infrastructure Standard for Data Centers," which defined four tiers of data center design and implementation guidelines. Tier 4 Data Center: A Tier 4 data center is an enterprise class data center tier with redundant and dual-powered instances of servers, storage, network links and power cooling equipment. "The Price of Data Center Availability—How much availability do you need? Data center operators can also pay a fee to rent server space in a colocation facility. Market intelligence firm International Data Corporation generally defines a data center as “hyperscale” when it exceeds 5,000 servers and 10,000 square feet. Many companies started building very large facilities, called Internet data centers (IDCs),[10] which provide enhanced capabilities, such as crossover backup: "If a Bell Atlantic line is cut, we can transfer them to ... to minimize the time of outage. [9][note 6] Increasingly, the division of these terms has almost disappeared and they are being integrated into the term "data center". Data center infrastructure is typically housed in secure facilities organized by halls, rows and racks, and supported by power and cooling systems, backup generators, and cabling plants. A raised floor standards guide named GR-2930 was developed by Telcordia Technologies, a subsidiary of Ericsson. Modern data centers make extensive use of monitoring and management software. Also common are monitoring systems for the network and some of the applications. Pour éviter les incendies, ils ont principalement des climatisations, système contre incendie...Il faut aussi une énergie en électricité vraiment importante et il faut qu'il n'est pas de coupure de courant. The data centers of some large companies are spaced all over the planet to serve the constant need for access to massive amounts of information. Un data center ayant le niveau Tier 1 ne possède qu’un seul circuit électrique ainsi qu’un circuit de distribution de refroidissement et il n’a pas de composants redondants. [87] In 2017 sales for data center hardware built to OCP designs topped $1.2 billion and are expected to reach $6 billion by 2021. Often available power is hardest to change. It was at this point that data centers became popular and began to resemble the ones described above. [91] The cooling of data centers is the second largest power consumer after servers. directly transferring the data to another site during the backup, using appropriate links, This page was last edited on 30 November 2020, at 06:51. The exhausts are pointed toward the air conditioning equipment. Class 2 single path with redundancy solution, Class 3 multiple paths providing a concurrent repair/operate solution, Class 4 multiple paths providing a fault tolerant solution (except during maintenance). "Three Signs it's time to transform your data center," August 3, 2010, Data Center Knowledge", "the Era of Great Data Center Consolidation", "This Wave of Data Center Consolidation is Different from the First One", "Top reasons to upgrade vintage data centers", "Complexity: Growing Data Center Challenge", "Carousel's Expert Walks Through Major Benefits of Virtualization", "The New urgency for Server Virtualization", "Gartner: Virtualization Disrupts Server Vendors", "Ritter, Ted. This differs from a traditional method of data center upgrades that takes a serial and siloed approach. Google détient plusieurs dizaines de datacenters localisés dans le monde entier. Data center architectures and requirements can differ significantly. The important distinction to make is this: Data centers are not defined by their physical size or style. [56], A modular data center may consist of data center equipment contained within shipping containers or similar portable containers. This tier gives its clients a guarantee of uptime and 2N (two times the amount required for operation) cooling and redundant power and infrastructure. ", Oct. 12, 2011, The Data Center Journal. The most commonly used energy efficiency metric of data center energy efficiency is power usage effectiveness (PUE), calculated as the ratio of total power entering the data center divided by the power used by IT equipment. a 65-story data center has already been proposed, the number of data centers as of 2016 had grown beyond 3 million USA-wide, and more than triple that number worldwide, size - one room of a building, one or more floors, or an entire building, and can hold 1,000 or more servers. [86], Power is the largest recurring cost to the user of a data center. The origins of the first data centers can be traced back to the 1940s and the existence of early computer systems like the Electronic Numerical Integrator and Computer (ENIAC). Non-mutually exclusive options for data backup are: Onsite is traditional,[111] and one major advantage is immediate availability. All of this demands a physical facility with physical security and sufficient square footage to house the entire collection of infrastructure and equipment. Le géant américain vient de mettre en service son deuxième data center européen, à Clonee en Irlande. Four Tiers are defined by the Uptime Institute standard: The field of data center design has been growing for decades in various directions, including new construction big and small along with the creative re-use of existing facilities, like abandoned retail space, old salt mines and war-era bunkers. "Next-Generation Data Centers," Forbes, March 15. data center chiller - A data center chiller is a cooling system used in a data center to remove heat from one element and deposit it into another element. The energy demand for information storage systems was also rising. Thermal zone mapping uses sensors and computer modeling to create a three-dimensional image of the hot and cool zones in a data center.[96]. Once a site is secured, the data center architecture can be designed with attention to the mechanical and electrical infrastructure, as well as the composition and layout of the IT equipment. [13] Gartner, another research company, says data centers older than seven years are obsolete. Although almost any suitable space could conceivably serve as a "data center," the deliberate design and implementation of a data center requires careful consideration. space, power, cooling, and costs in the data center. Récupérer la chaleur d'un data center pour se chauffer. A data center stores and shares applications and data. Please check the box if you want to proceed. Commentary on introduction of Energy Star for Data Centers, What IBM calls "PTAM: Pickup Truck Access Method. A related concept is Composable infrastructure, which allows for the dynamic reconfiguration of the available resources to suit needs, only when needed.[108]. In May 2011, data center research organization Uptime Institute reported that 36 percent of the large companies it surveyed expect to exhaust IT capacity within the next 18 months. For example, safety is often reflected in the layout of doorways and access corridors, which must accommodate the movement of large, unwieldy IT equipment, as well as permit employees to access and repair the infrastructure. [4][5], Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g. [94] By predicting the effects of these environmental conditions, CFD analysis in the data center can be used to predict the impact of high-density racks mixed with low-density racks[95] and the onward impact on cooling resources, poor infrastructure management practices and AC failure or AC shutdown for scheduled maintenance. [70] For higher power density facilities, electricity costs are a dominant operating expense and account for over 10% of the total cost of ownership (TCO) of a data center. La gestion de l'infrastructure d'un centre de données (anglais : Data Center Infrastructure Management, DCIM) est réalisée au moyen d'un ensemble d'outils, de procédures et de méthodes.. Dans le langage courant, l'acronyme DCIM est utilisé principalement pour désigner le système informatique de supervision de ces infrastructures. It comprises components that include switches, storage systems, servers, routers, and security devices. A simple data center may need only a few kilowatts of energy, but an enterprise-scale data center installation can demand tens of megawatts or more. Data center infrastructure is typically housed in secure facilities organized by halls, rows and racks, and supported by power and cooling systems, backup generators, and cabling plants. [82], The focus of measuring and analyzing energy use goes beyond what's used by IT equipment; facility support hardware such as chillers and fans also use energy. Vous souhaitez étudier les normes, les réglementations ainsi que les habitudes des usages. The goal is to allow individual users to provision workloads and other computing resources on demand without IT administrative intervention. Il comprend divers composants, notamment des commutateurs, des systèmes de stockage, des serveurs, des routeurs et des périphériques de sécurité. A data center must also contain an adequate infrastructure, such as power distribution and supplemental power subsystems. Vous souhaitez rationnaliser les ressources, stocker et sécuriser les données de l’entreprise, renforcer la sécurité et la disponibilité des applications et simplifier l’exploitation de vos Data Centers. Case studies have shown that by addressing energy efficiency holistically in a data center, major efficiencies can be achieved that are not possible otherwise.[93].
