Several Quagga contributors, including Cumulus Networks , 6WIND , and BigSwitch Networks, citing frustration about the pace of development, decided to fork the software and form their own community. This free and open-source software article

80-423: A Bell Atlantic line is cut, we can transfer them to ... to minimize the time of outage." The term cloud data centers (CDCs) has been used. Data centers typically cost a lot to build and maintain. Increasingly, the division of these terms has almost disappeared and they are being integrated into the term data center . The global data center market saw steady growth in the 2010s, with a notable acceleration in

120-782: A ONIE install environment gives data centers the choice of network operating system, disaggregating the networking hardware from the operating system. The Cumulus Linux operating system can be installed on all ONIE compliant switches. Data centers A data center is a building , a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems . 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., air conditioning , fire suppression), and various security devices. A large data center

160-520: A data center may reach as high as 92-96 dB(A). Residents living near data centers have described the sound as "a high-pitched whirring noise 24/7", saying “It’s like being on a tarmac with an airplane engine running constantly ... Except that the airplane keeps idling and never leaves.” External sources of noise include HVAC equipment and energy generators. The field of data center design has been growing for decades in various directions, including new construction big and small along with

200-454: A data center to grow and change over time. Data center modules are pre-engineered, standardized building blocks that can be easily configured and moved as needed. A modular data center may consist of data center equipment contained within shipping containers or similar portable containers. Components of the data center can be prefabricated and standardized which facilitates moving if needed. Temperature and humidity are controlled via: It

240-493: A data center. In 2020, data centers (excluding cryptocurrency mining) and data transmission each used about 1% of world electricity. Although some of this electricity was low carbon, the IEA called for more "government and industry efforts on energy efficiency, renewables procurement and RD&D", as some data centers still use electricity generated by fossil fuels. They also said that lifecycle emissions should be considered, that

280-459: A range of underfloor panels can create efficient cold air pathways directed to the raised-floor vented tiles. Either the cold aisle or the hot aisle can be contained. Another option is fitting cabinets with vertical exhaust duct chimneys . Hot exhaust pipes/vents/ducts can direct the air into a Plenum space above a Dropped ceiling and back to the cooling units or to outside vents. With this configuration, traditional hot/cold aisle configuration

320-407: A traditional method of data center upgrades that takes a serial and siloed approach. The typical projects within a data center transformation initiative include standardization/consolidation, virtualization , automation and security. A raised floor standards guide named GR-2930 was developed by Telcordia Technologies , a subsidiary of Ericsson . Although the first raised floor computer room

The company designed and sold a Linux operating system for industry standard network switches , along with management software, for large datacenter , cloud computing , and enterprise environments. In May 2020, American semiconductor manufacturer Nvidia announced it

400-531: Is also a concern, and for this reason, a data center has to offer a secure environment that minimizes the chances of a security breach. A data center must, therefore, keep high standards for assuring the integrity and functionality of its hosted computer environment. Industry research company International Data Corporation (IDC) puts the average age of a data center at nine years old. Gartner , another research company, says data centers older than seven years are obsolete. The growth in data (163 zettabytes by 2025 )

440-946: Is an industrial-scale operation using as much electricity as a medium town. Estimated global data center electricity consumption in 2022 was 240–340  TWh , or roughly 1–1.3% of global electricity demand. This excludes energy used for cryptocurrency mining, which was estimated to be around 110 TWh in 2022, or another 0.4% of global electricity demand. The IEA projects that data center electric use could double between 2022 and 2026. High demand for electricity from data centers, including by cryptomining and artificial intelligence , has also increased strain on local electric grids and increased electricity prices in some markets. Data centers can vary widely in terms of size, power requirements, redundancy, and overall structure. Four common categories used to segment types of data centers are onsite data centers, colocation facilities, hyperscale data centers, and edge data centers. Data centers have their roots in

480-559: Is important that computers do not get humid or overheat, as high humidity can lead to dust clogging the fans, which leads to overheat, or can cause components to malfunction, ruining the board and running a fire hazard. Overheat can cause components, usually the silicon or copper of the wires or circuits to melt, causing connections to loosen, causing fire hazards. Backup power consists of one or more uninterruptible power supplies , battery banks, and/or diesel / gas turbine generators. To prevent single points of failure , all elements of

520-451: Is including embodied emissions, such as in buildings. Data centers are estimated to have been responsible for 0.5% of US greenhouse gas emissions in 2018. Some Chinese companies, such as Tencent , have pledged to be carbon neutral by 2030, while others such as Alibaba have been criticized by Greenpeace for not committing to become carbon neutral. Google and Microsoft now each consume more power than some fairly big countries, surpassing

560-458: Is not a requirement. Data centers feature fire protection systems, including passive and Active Design elements, as well as implementation of fire prevention programs in operations. Smoke detectors are usually installed to provide early warning of a fire at its incipient stage. Although the main room usually does not allow Wet Pipe-based Systems due to the fragile nature of Circuit-boards , there still exist systems that can be used in

600-495: Is one factor driving the need for data centers to modernize. Focus on modernization is not new: concern about obsolete equipment was decried in 2007, and in 2011 Uptime Institute was concerned about the age of the equipment therein. By 2018 concern had shifted once again, this time to the age of the staff: "data center staff are aging faster than the equipment." The Telecommunications Industry Association 's Telecommunications Infrastructure Standard for Data Centers specifies

640-418: Is similar to how large-scale food companies refrigerate and store their products. Computer cabinets/ Server farms are often organized for containment of hot/cold aisles. Proper air duct placement prevents the cold and hot air from mixing. Rows of cabinets are paired to face each other so that the cool and hot air intakes and exhausts don't mix air, which would severely reduce cooling efficiency. Alternatively,

680-457: The dot-com bubble of 1997–2000. Companies needed fast Internet connectivity and non-stop operation to deploy systems and to establish a presence on the Internet. Installing such equipment was not viable for many smaller companies.

880-489: The data center is large or contains sensitive information. Fingerprint recognition mantraps are starting to be commonplace. Logging access is required by some data protection regulations; some organizations tightly link this to access control systems. Multiple log entries can occur at the main entrance, entrances to internal rooms, and at equipment cabinets. Access control at cabinets can be integrated with intelligent power distribution units , so that locks are networked through

920-494: The electrical systems, including backup systems, are typically given redundant copies , and critical servers are connected to both the A-side and B-side power feeds. This arrangement is often made to achieve N+1 redundancy in the systems. Static transfer switches are sometimes used to ensure instantaneous switchover from one supply to the other in the event of a power failure. Options include: Air flow management addresses

960-593: The elevated floor). A single mainframe required a great deal of power and had to be cooled to avoid overheating. Security became important – computers were expensive, and were often used for military purposes. Basic design guidelines for controlling access to the computer room were therefore devised. During the microcomputer industry boom of the 1980s, users started to deploy computers everywhere, in many cases with little or no care about operating requirements. However, as information technology (IT) operations started to grow in complexity, organizations grew aware of
