DCIM - Data Center Infrastructure Management The name of the game. Some of the considerations in the design of data centers are: Various metrics exist for measuring the data-availability that results from data-center availability beyond 95% uptime, with the top of the scale counting how many "nines" can be placed after "99%". Qu'est ce qu'un SLA? At a minimum, data centers serve as the principal repositories for all manner of IT equipment, including servers, storage subsystems, networking switches, routers and firewalls, as well as the cabling and physical racks used to organize and interconnect the IT equipment. [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. 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. overview of the Brocade VDX 8770 data center-class switch, Dell's OpenManage software as a service products, Dell E-series of data center-class switches, Cisco Nexus 9500 series of data center switches, Juniper EX9200 data center-class switches, Learn how to incorporate essential components within your edge architecture, Discover the nuances of data center commissioning to get your facilities online, 3 steps to help with data center efficiency, Data center admins now require a broader skill set, Understand data center planning and design with help from this guide, Heat and Vibration: Two Factors that Can Kill Your Data, Cloud-Based Solutions are the Future of the Digital Workforce, E-Guide: Expert Tips for Building a Flexible Data Center, Learn how to start using Docker on Windows Server 2019, Boost Windows Server performance with these 10 tips, Explore the benefits of Azure AD vs. on-prem AD, VMware NSX vs. Microsoft Hyper-V network virtualization, Use virtual clusters to avoid container sprawl, Software-defined power offers benefits, but lacks popular interest, AWS re:Invent 2020 underscores push toward cloud in pandemic, Multi-cloud networking -- how to choose the right path. In the days of large, centralized IT operations, this department and all the systems resided in one physical place, hence the name data center. Bullock, Michael. 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). These were called "servers", as timesharing operating systems such as Unix rely heavily on the client–server model to facilitate sharing unique resources between multiple users.

Koomey, C. Belady, M. Patterson, A. Santos, K.D. Securing: Protection of virtual systems is integrated with existing security of physical infrastructures. 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. A tier 1 data center can be little more than a powered warehouse. Power cooling density is a measure of how much square footage the center can cool at maximum capacity. No problem! Methods used for transporting data are:[112]. 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. Arctic locations can use outside air, which provides cooling, are getting more popular.[97]. Thus, these critical data center facilities usually require a significant investment of supporting systems, including air conditioning/climate control systems, fire suppression/smoke detection, secure entry and identification and raised floors for easy cabling and water damage prevention. Data center tiers. 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. Google détient plusieurs dizaines de datacenters localisés dans le monde entier. For example, critical servers might be placed in a cool zone that is serviced by redundant AC units. See more. Smoke detectors are usually installed to provide early warning of a fire at its incipient stage. Do Not Sell My Personal Info. A raised floor standards guide named GR-2930 was developed by Telcordia Technologies, a subsidiary of Ericsson. [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. For this reason, data center infrastructures are more often equipped with heat pumps. Review your networking options and choose ... All Rights Reserved, Les Data Center Infrastructure Management (DCIM) ou gestionnaires d’infrastructure de centre de données sont des outils permettant de gérer et de surveiller l’utilisation des Data Centers et leur consommation de ressources et d’énergie. 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. [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. Stay on top of the latest news, analysis and expert advice from this year's re:Invent conference. Data center architectures and requirements can differ significantly. These specialized computer rooms were dubbed data centers within the companies, and the term gained traction. 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. This configuration of the air conditioning equipment is known as in-row cooling. The result is alternating hot and cold aisles, with the exhausts creating a hot aisle and the intakes creating a cold aisle. 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. 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]. Data center operators can also pay a fee to rent server space in a colocation facility. Colocation is an appealing option for organizations that want to avoid the large capital expenditures associated with building and maintaining their own data centers. 'Mass' data centers like Google or Facebook don't need to be near population centers. The growth of virtualization has added another important dimension to data center infrastructure management. [21] The typical projects within a data center transformation initiative include standardization/consolidation, virtualization, automation and security. Learn more. 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. [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. At its most basic, it is a physical place that houses a computer network's most critical systems, including backup power supplies, air conditioning, and security applications.We're talking a large amount of data here, stored in a large number of computers. Access control at cabinets can be integrated with intelligent power distribution units, so that locks are networked through the same appliance. Curtailed and clipped energy can be used to secure transactions on the Bitcoin blockchain providing another revenue stream to renewable energy producers.[103]. 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. Mechanical engineering infrastructure - heating, ventilation and air conditioning (. Additional off site monitoring systems are also typical, in case of a failure of communications inside the data center. Building or room used to house computer servers and related equipment, International standards EN50600 and ISO22237 Information technology — Data centre facilities and infrastructures, Uptime Institute – Data center Tier Classification Standard, Computational fluid dynamics (CFD) analysis. [85], In 2011 Facebook, Rackspace and others founded the Open Compute Project (OCP) to develop and publish open standards for greener data center computing technologies. "[17], The Telecommunications Industry Association's Telecommunications Infrastructure Standard for Data Centers[18] specifies the minimum requirements for telecommunications infrastructure of data centers and computer rooms including single tenant enterprise data centers and multi-tenant Internet hosting data centers. Virtualization now supports the abstraction of servers, networks and storage, allowing every computing resource to be organized into pools without regard to their physical location. [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. These early machines were complex to maintain and operate and had a slew of cables connecting all the necessary components. Each subsequent tier is intended to provide more resilience, security and reliability than the previous tier. 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. Redundancy of the Internet connection is often provided by using two or more upstream service providers (see Multihoming). This information can help to identify optimal positioning of data center equipment. 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. A data center provider called Switch defined its own Tier 5 level in 2017. [13] Gartner, another research company, says data centers older than seven years are obsolete. 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". Level 4 - designed to host the most mission critical computer systems, with fully redundant subsystems, the ability to continuously operate for an indefinite period of time during primary power outages. Making servers taller left space for more effective heat sinks and enabled the use of fans that moved more air with less energy. Virtualization: Lowers capital and operational expenses. They may be applied to data center spaces housing data processing or Information Technology (IT) equipment. Data center designs must also implement sound safety and security practices.

This arrangement is often made to achieve N+1 redundancy in the systems. Administrators can then provision workloads, storage instances and even network configuration from those common resource pools. air conditioning, fire suppression) and various security devices. Until the early 1960s, it was primarily the government that used computers, which were large mainframes housed in rooms that today we call data centers. 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 . It measures the percentage of power used by overhead (cooling, lighting, etc.). Sa disponibilité est de 99,67 % et ses clients doivent prendre en compte une interruption annuelle de 28 heures et huit dixièmes. Energy use is a central issue for data centers. All of the devices are accessed and managed by remote systems, with automation programs used to perform unattended operations. A single mainframe required a great deal of power and had to be cooled to avoid overheating. "In year four, our cost per kilowatt a month is about a third of what it would have been." 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. 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. It also facilitates performing routine maintenance on either physical or virtual systems all while minimizing interruption. [90] A power and cooling analysis can help to identify hot spots, over-cooled areas that can handle greater power use density, the breakpoint of equipment loading, the effectiveness of a raised-floor strategy, and optimal equipment positioning (such as AC units) to balance temperatures across the data center. 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. Consolidation typically occurs during mergers and acquisitions when the majority business doesn't need the data centers owned by the subordinate business. 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. Please check the box if you want to proceed. Raised floor cabling, for security reasons and to avoid the addition of cooling systems above the racks. [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. 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. Il s’agit d’un référentiel centralisé destiné à différents stockages et à la gestion de données informatiques. The two organizations in the United States that publish data center standards are the Telecommunications Industry Association (TIA) and the Uptime Institute. Vous souhaitez étudier les normes, les réglementations ainsi que les habitudes des usages. A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations. [42][43], The first purpose of the raised floor was to allow access for wiring. These standards will protect most companies. It was at this point that data centers became popular and began to resemble the ones described above. 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. This product overview outlines the HP FlexFabric 12500 series, Learn more about the Juniper EX9200 data center-class switches. "Bouley, Dennis (editor). However, the subsequent rise of virtualization has allowed for much more productive use of IT equipment, resulting in much higher efficiency, lower energy use and energy cost mitigation. While there isn’t a single, comprehensive definition for HDCs, we understand that, at their most basic, HDCs are significantly larger facility than a typical enterprise data centers. A data center stores and shares applications and data. 2010", "Data centers are aging, unsuited for new technologies", "Data center staff are aging faster than the equipment", "TIA-942 Certified Data Centers - Consultants - Auditors - TIA-942.org", "Telecommunications Standards Development", "GR-3160 - Telecommunications Data Center - Telcordia", "Tang, Helen. 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. 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. data center resiliency: Resiliency is the ability of a server , network, storage system, or an entire data center , to recover quickly and continue operating even when there has been an equipment failure, power outage or other disruption. Le SLA, ou Service Level Agrement est l'engagement que le data center prend envers le client pour lui assurer un service, une qualité et une disponibilité de 99,95 %. The wholesale data center model "was the cheapest way to buy a long-term position in kilowatts," Parris said. Data center designs also recognize the importance of energy efficiency. [8][note 4], The boom of data centers came during the dot-com bubble of 1997–2000. This design had long been part of Google data centers. 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 micro-data center is a relatively small, modular system that serves smaller businesses or provides additional resources for an enterprise. Data center modules are pre-engineered, standardized building blocks that can be easily configured and moved as needed. 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. Définitions de Datacenter, synonymes, antonymes, dérivés de Datacenter, dictionnaire analogique de Datacenter (français) The term "Machine Room" is at times used to refer to the large room within a Data Center where the actual Central Processing Unit is located; this may be separate from where high-speed printers are located. [56], A modular data center may consist of data center equipment contained within shipping containers or similar portable containers. Hot spot A club or restaurant that is difficult to get into. [57] Components of the data center can be prefabricated and standardized which facilitates moving if needed.[58]. Market intelligence firm International Data Corporation generally defines a data center as “hyperscale” when it exceeds 5,000 servers and 10,000 square feet. How would you describe your organization's data center infrastructure? We'll send you an email containing your password. The topology proposed in this document is intended to be applicable to any size data center.[19]. Submit your e-mail address below. 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. A data center must, therefore, keep high standards for assuring the integrity and functionality of its hosted computer environment. The Cisco Nexus 7700 data center switch series is designed for enterprises and highly virtualized environments. There are a couple ways to connect the disparate pieces of a multi-cloud architecture. 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. Fingerprint recognition mantraps is starting to be commonplace. [11] Data centers typically cost a lot to build and to maintain. 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. Computer cabinets are often organized for containment of hot/cold aisles.

There are reportedly more than 3 million data centers of various shapes and sizes in the world today [source: Glanz]. Over the history of computing, as computers become smaller and networks become bigger, the data center has evolved and shifted to accommodate the necessary technology of the day. These types of data centers require very high connectivity and are mainly responsible for driving content delivery, mobile services, and cloud services. Tier 1 is the simplest infrastructure, while Tier 4 is the most complex and has the most redundant components. However, it wasn't until the 1990s, when IT operations started to gain complexity and inexpensive networking equipment became available, that the term data center first came into use. An energy efficiency analysis measures the energy use of data center IT and facilities equipment. Instead, data centers often use environmentally friendly chemical fire suppression systems, which effectively starve a fire of oxygen while mitigating collateral damage to the equipment. À titre de comparaison, un micro-datacenter regrouperait moins de 10 serveurs et moins de 100 machines virtuelles dans une caisse de 50 cm seulement. An overview of the Brocade VDX 8770 data center-class switch family, Learn how Dell's OpenManage software as a service products can ease the various challenges that come with managing a data center. Focus on modernization is not new: concern about obsolete equipment was decried in 2007,[16] and in 2011 Uptime Institute was concerned about the age of the equipment therein. "Stockholm sets sights on data center customers", In a world of rapidly increasing carbon emissions from the ICT industry, Norway offers a sustainable solution. Thank you Margaret. All of these issues are guided by the availability and efficiency goals of the desired data center tier. State-of-the-art is estimated to be roughly 1.2. [55], Modularity and flexibility are key elements in allowing for a data center to grow and change over time. 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. Non-mutually exclusive options for data backup are: Onsite is traditional,[111] and one major advantage is immediate availability. 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. Un data center est organisé en baies, armoires pouvant accueillir des éléments en rack dans des emplacements de taille normalisée d'une largeur de 19 pouces (48.26 cm). [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.
