Together, all their elements create a structure designed to house and process large amounts of data, which can be consulted from anywhere with an Internet connection.<\/p>\n\n\n\n<p>In order for these infrastructures to operate securely and effectively, they must have a whole series of key components, ranging from servers to management elements. However, there are many other technical terminologies more unfamiliar to the general public that provide insight into how these large data centers operate.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"key-elements-and-descriptions-of-a-data-center\">Key elements and descriptions of a Data Center<\/h2>\n\n\n\n<p>Next, we will review a glossary with key words and terminologies within the usual jargon when we talk about a Data Center:<\/p>\n\n\n\n<p>Sustainability is one of the main guidelines in the data center industry and, therefore, the first terms will be related to it:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"terms-related-to-efficiency-and-sustainability\">Terms related to Efficiency and Sustainability:<\/h3>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>PUE (Power Usage Effectiveness):<\/strong> An energy efficiency indicator that measures the total amount of energy used by a data center, divided by the energy consumed by the IT equipment. A PUE of 1.0 would be fully efficient, indicating that all energy is used for computing.<\/li><li><strong>WUE (Water Usage Effectiveness):<\/strong> Similar to PUE, but focuses on the efficiency of water usage in a data center. It measures the amount of water used by the data center, including cooling and other operations, in relation to the energy consumed.<\/li><li><strong>DCiE (Data Center Infrastructure Efficiency):<\/strong> This is the inverse of PUE and expresses the efficiency of the data center infrastructure. It is calculated by dividing the IT (information technology) load by the total load of the data center.<\/li><li><strong>Renewable Energy Credits (RECs):<\/strong> Certificates that represent the generation of a certain amount of renewable energy. Data centers often seek to use RECs as part of their efforts to reduce their carbon footprint.<\/li><\/ol>\n\n\n\n<p>On the other hand, a data center contains a large amount of equipment dedicated to data processing, as well as cooling and electrical back-up technology, to ensure 24x7x365 operation:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"terms-related-to-technology-and-equipment\">Terms related to Technology and Equipment:<\/h3>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Climatization:<\/strong> Cooling systems that control the temperature and humidity in the data center to maintain equipment in optimal operating conditions.<\/li><li><strong>Chiller:<\/strong> Device used in the air conditioning system to cool the water that is then used to control the temperature inside the IT rooms of the data center.<\/li><li><strong>CRAC (Computer Room Air Conditioner) \/ CRAH (Computer Room Air Handler): <\/strong>Air conditioning units specifically designed to cool the environment in an IT room in a data center.<\/li><li><strong>AHU (Air Handling Unit):<\/strong> Units that deliver pre-treated outside air at an optimum temperature to the interior of an IT room.<\/li><li><strong>Rack:<\/strong> A cabinet or structure that houses various servers, storage devices and network equipment in an organized manner. Racks facilitate space management and cable management.<\/li><li><strong>Hot Aisle\/Cold Aisle:<\/strong> A strategy for arranging racks in a data center to improve cooling efficiency. Racks are oriented so that the hot sides of the equipment (where hot air is expelled) face each other (hot aisle), or the cold sides face each other (cold aisle). In recent years, techniques such as aisle enclosures have begun to be used to better confine the temperature and increase energy efficiency.<\/li><li><strong>Inrack Cooling:<\/strong> Cooling systems integrated directly into server racks to dissipate heat more directly.<\/li><li><strong>Generator (GenSet)<\/strong>: A device that produces electrical power autonomously, usually using fossil fuels, to back up the power supply in the event of an extended power outage.<\/li><li><strong>UPS (Uninterruptible Power Supply):<\/strong> A device that provides continuous electrical power to connected equipment in the event of power outages. It helps prevent data loss and ensures operational continuity between the time the power grid goes down and the generators come on line.<\/li><li><strong>Fiber Optic Network:<\/strong> A data transmission system that uses glass or plastic wires to transmit information in the form of light pulses.<\/li><li><strong>Server:<\/strong> A device or program that provides services to other computers (called clients) on a network. In a data center, servers can run applications, store data, or perform various tasks.<\/li><li><strong>Switch:<\/strong> A network device that connects various devices within the data center and facilitates communication between them.<\/li><li><strong>Firewall:<\/strong> Device or software that controls network traffic according to predefined rules, in order to protect the network against external threats and attacks.<\/li><li><strong>Router:<\/strong> Device that directs data traffic between different networks. In a data center, it can manage the connection between the internal and external network.<\/li><li><strong>Virtualization:<\/strong> Technology that allows running multiple operating systems or applications on a single physical server, maximizing efficiency and resource utilization.<\/li><\/ol>\n\n\n\n<p>Finally, to ensure the constant operation and physical integrity of the data, it is essential to have high levels of security and fire protection:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"terms-related-to-safety-and-fire-protection\">Terms related to safety and fire protection:<\/h3>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>BMS (Building Management System):<\/strong> It is the data center supervision system: through this software, all the parameters of a data center are monitored and trends can be generated to optimize its operation.<\/li><li><strong>Monitoring and Management:<\/strong> Tools and systems to monitor performance, security and other aspects of the data center, facilitating management and informed decision making.<\/li><li><strong>Water Suppression Systems:<\/strong> Systems that release water through sprinklers. This can be water mist, to ensure that IT room equipment is not damaged.<\/li><li><strong>Sprinklers (Automatic Sprinkler System)<\/strong>: Piping network with sprinklers installed in the ceiling that are automatically activated when they detect heat and\/or smoke. They help control or extinguish fire.<\/li><li><strong>Gas Extinguishing Systems<\/strong>: Systems that release gaseous extinguishing agents to extinguish fire without damaging electronic equipment.<\/li><li><strong>Oxygen Suppression Systems:<\/strong> Control the level of oxygen in a room to reduce the possibility of a fire spreading, since fires require oxygen to sustain themselves.<\/li><\/ol>\n\n\n\n<p>These terms provide an overview of the key components, as well as the most commonly used terminologies when talking about data centers. It is through the complex optimization and management of all these elements and nomenclatures that the data-based services we perceive from the outside operate smoothly and without interruption.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Data Centers are complex infrastructures, containing all kinds of equipment, components and management elements.
